SECTION III: INSTALLATION INSTRUCTIONS  
WARNING  
INSTALLATION OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT TO THAT OF A  
LICENSED PLUMBER. Plumbing, air supply, venting, gas supply and electrical work are required.  
DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT CERTAIN OF THE  
FOLLOWING:  
Liquefied petroleum gases/propane gas and natural gas have an odorant added by the gas  
supplier that aids in detection of the gas.  
Most people recognize this odor as a “sulfur” or “rotten egg” smell.  
Other conditions, such as “odorant fade” can cause the odorant to diminish in intensity, or  
“fade,” and not be as readily detectable.  
If you have a diminished sense of smell, or are in any way unsure of the presence of gas,  
immediately contact your gas supplier from a telephone in another building.  
Gas detectors are available. Contact your gas supplier or plumbing professional for more  
information.  
Liquefied petroleum gases/propane gas is heavier than air and will remain at floor level if there is a  
leak. Basements, crawl spaces, closets and areas below ground level will serve as pockets for  
accumulation of leaking gas. Before lighting, smell all around the appliance area for gas. Be sure  
to smell next to the floor.  
IF YOU SMELL GAS:  
Do not try to light any appliance.  
Do not touch any electric switch; do not use any telephone in your building.  
Immediately call your gas supplier from a telephone in another building. Follow the gas  
supplier’s instructions.  
If you cannot reach your gas supplier, call the fire department.  
DO NOT OPERATE THE APPLIANCE UNTIL THE LEAKAGE IS CORRECTED!  
WARNING  
This water heater must be located in an area where leakage of the heat exchanger coil, water line  
connections, or the pressure relief valve will not result in damage to the area adjacent to the water  
heater or to lower floors of the structure. When such locations cannot be avoided, a suitable drain  
pan must be installed under the water heater. The drain pan depth must be suitable for draining and  
collecting water, and have a minimum length and width of at least four (4) inches (10.2 cm)  
measured from the jacket of the water heater. The drain pan, as described above, can be  
purchased from your plumbing professional. The drain pan must be piped to an adequate drain.  
The piping must be at least ¾ inch (1.9 cm) in diameter and pitched for proper drainage.  
CAUTION  
If building cold water supply has a back-flow preventer, check valve or water meter with check valve,  
provisions for thermal expansion of water in the hot water system must be provided.  
WARNING  
Pressure relief valve discharge piping must be piped near floor to eliminate potential of severe  
burns. Do not pipe in any area where freezing could occur. Do not install any shut-off valves, plugs  
or caps to the temperature and pressure relief valve or piping.

1. All equipment is carefully manufactured, inspected and packed.  
2. Any claims for damage or shortage in shipment must be filed immediately with Bradford White  
Corporation and noted on the Bill of Lading.  
WATER HEATER LOCATION  
1. The TGHE series water heaters may be vented either horizontally through an outside wall or  
vertically through the roof using the venting components designed for this water heater. Contact  
your Bradford White supplier or those suggested in this manual to order the required venting  
components. The venting system should be as short as possible. Refer to the Venting System  
Installation section of this Installation and Operation Manual for the vent terminal location  
restrictions before choosing a final location for the water heater.  
2. The water heater must be installed on a wall capable of supporting up to 71 pounds (32 kg),  
depending on the model. Locate the water heater at a height convenient for servicing and above  
the reach of small children.  
3. Refer to Table 3 for minimum clearances to combustibles.  
4. If the water heater is installed in a confined space, such as a closet, ventilation air must be  
provided to prevent increased room temperature. Excessive ambient temperatures surrounding

MOUNT WATER HEATER ON THE WALL  
Determine the proper height and location for the water heater to be installed. Consider the venting  
system, as well as the water and gas connections. Allow enough room for servicing the water heater and  
maintain the clearances from combustible materials. The water heater is supported on the wall by means  
of a top and bottom slotted angle bracket. For convenience, the center hole of the bracket is slotted so  
that a center screw may be first installed in the wall for hanging the water heater on the wall. Two more  
screws are then added on the ends of the bracket to secure the water heater. Wall anchors should be  
used for the bracket holes unless the bracket lines up with a stud. As an alternative, a suitable piece of  
plywood may be cut to span the wall studs and the brackets fastened to the plywood. Make sure the  
anchors are rated to support up to the 71 lbs. (32 kg) weight of the water heater.

SECTION IV: WATER CONNECTIONS  
WARNING  
Failure to install and maintain a new, listed pressure relief valve will release the manufacturer from  
any claim, which might result from excessive temperature and pressures.  
Keep clear of the pressure relief valve discharge line outlet. The discharge may be hot enough to  
cause scald injury. The water is under pressure and may splash.  
WARNING  
DO NOT reverse the inlet and outlet (cold and hot water) connections on the water heater. This may  
cause a hazardous operating condition or the water heater may be inoperable  
WATER QUALITY  
The EverHotwater heater must have the water quality within the following limits for long life and reliable  
operation. The water supply should be tested to make sure the quality is within the specified limits. If  
there is a problem with the water quality, contact your local water conditioning company for equipment to

NOTICE  
If the EverHot water heater is operated under hard water conditions without a water conditioner, the  
diagnostic code “LC” may flash on the water heater’s control. This code means the heat exchanger coil  
is beginning to accumulate mineral deposits and MUST be flushed (see Section IX, “Flushing Procedure  
for Mineral Scale Removal…”). Contact your installer for a qualified service technician to flush the heat  
exchanger. A water conditioner may be needed to prevent this condition from re-occurring.  
CAUTION  
Failure to flush the water heater when “LC” is flashing will cause damage to the heat exchanger.  
Damage caused by mineral scale build up is not covered by the water heater warranty.  
INSTRUCTIONS FOR CONNECTIONS  
1. BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY  
VALVE. After shutting off the main water supply, open a faucet to relieve the water line pressure  
to prevent any water from leaking out of the pipes while making the water connections to the  
water heater. The COLD water inlet and HOT water outlet are identified on the bottom casing of  
the water heater. Make the proper plumbing connections between the water heater and the  
plumbing system to the house. All soldering materials and piping must be compatible with  
13  
Download from Www.Somanuals.com. All Manuals Search And Download.  
potable water. Unions should be installed on both the hot and cold water lines for future servicing  
and disconnection of the water heater. Install a shut-off valve in the cold water supply line.  
2. In order to service the water heater in the event the heat exchanger needs to be flushed of  
mineral deposits, tee fittings with shut-off valves and service connections to hoses should be  
installed. Also, install a shut-off valve to the hot water supply to isolate the service tee fittings. A  
plumbing installation kit, which includes these fittings and a pressure relief valve, is available from  
your supplier. Refer to the piping diagrams in Section IV, “Water Connections.”  
3. Install a pressure relief valve on a tee connection from the hot water outlet piping from the water  
heater. Refer to the piping diagrams (Figure 4 and Figure 5) and pressure relief valve warning in  
Section IV, “Water Connections.”  
4. In cold climates, where piping can freeze during an extended power failure, drain solenoid valves  
should be installed on the cold and hot water supply lines to allow water to drain from the water  
heater when power is interrupted. Refer to the piping diagram (Figure 6) “Recommended Piping  
for Power Failure Freeze Protection” in Section IV, and contact your Bradford White dealer if  
assistance is needed.  
5. If this water heater is installed in a closed water supply system, such as the one having a back-  
flow preventer in the cold water supply, provisions must be made to control thermal expansion.  
DO NOT operate this water heater in a closed system without provisions for controlling thermal  
expansion. Warranties do not cover damages from thermal expansions, such as pressure bulges  
and/or deformities. Your water supplier or local plumbing inspector should be contacted on how  
to control this situation.  
6. Purge the cold water line prior to connecting to the water heater to remove debris. Debris will  
clog the mesh strainer on the inlet filter. The inlet strainer prevents debris from damaging the  
flow sensor or clogging the coil. It may need to be cleaned periodically and should be cleaned  
after the initial operation. DO NOT operate the water heater without the filter in place. In areas  
where sediment may be periodically present in the water supply, a Y-type strainer (#20 mesh) or  
cartridge filter should be installed on the cold water inlet to the water heater to prevent the water  
heater fine mesh strainer from getting plugged and restricting water flow.  
7. After installation of the water lines, open the main water supply valve and fill the water heater.  
While the water heater is filling, open several hot water faucets to allow air to escape from the  
water system. When a steady stream of water flows through the faucets, close them and check  
all water connections for possible leaks.  
8. This water heater may also be connected to a circulating pump or storage tank for increased flow  
capacity during high demand periods.  
9. Commercial installations may require more than one water heater piped together in a manifold to  
supply enough capacity for high temperature and high water flow applications. Special controls  
are available from your Bradford White supplier for operating more than one water heater  
together. These controls stage the operation of the water heaters for the flow rates and control  
the amount of flow through each water heater. Order p/n MSA-2M for the electronic manifold  
control for the first and second water heater and p/n MSA-2S for the wiring harness for each  
additional water heater to be controlled. A maximum of (5) water heaters can be connected  
together. Alternatively, to connect only (2) water heaters, an EZConnectTM harness, p/n

Recommended Piping for Power Failure Freeze Protection  
As long as electrical power and gas are supplied to the EverHotwater heater, freeze protection is  
provided to the heat exchanger and piping inside the water heater with ambient temperatures as cold as  
-22F (-30C), when protected from direct wind exposure. In the event of a power failure with ambient  
temperatures below freezing, the water heater must be drained of all water to prevent freeze damage.  
The water heater may be drained manually, or automatically, through the installation of the optional  
solenoid valves, as shown in the following illustration. The drain solenoids are recommended for very  
cold climates to prevent water heater freeze damage where power failures from ice and windstorms  
occur.  
The electrical connections for the two solenoids must be tied to the 120 volt main power supply (black  
and white wires). When the electrical power to the water heater fails, the ¾” solenoid on the cold water  
inlet pipe closes, stopping water flow into the water heater. The drain solenoid opens, allowing the water  
heater and connected piping to drain. Make sure the piping from the drain solenoid is run to a suitable  
drain or outside the building to prevent water damage.  
Figure 6. Recommended Piping for Freeze Protection.  
CAUTION  
Heat trace all water pipe and fittings located outside the home (attic, crawl space) or building  
structure. All pipe and fittings shown below dashed line (see Figure 6) should be located inside  
home or building structure. The vacuum breaker line should be located inside the building structure.

PRESSURE RELIEF VALVE  
WARNING  
Keep clear of the pressure relief valve discharge line outlet. The discharge may be hot  
enough to cause scald injury. The water is under pressure and may splash.  
For protection against excessive pressure, install pressure protective equipment required by  
local codes, but not less than a pressure relief valve certified by a nationally recognized  
testing laboratory that maintains periodic inspection of production of listed equipment or  
materials as meeting the requirements of the Standard for Relief Valves and Automatic Gas  
Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 and the Standard CAN1-4.4  
Temperature, Pressure, Temperature and Pressure Relief Valves and Vacuum Relief Valves.  
The pressure relief valve must be marked with a maximum set pressure not to exceed the  
maximum working pressure of the water heater. The pressure relief valve rating must not be  
less than the hourly rating of the water heater.  
Install the pressure relief valve into a tee connection from the hot water outlet of the water  
heater.  
Note: Some models may already be equipped or supplied with an installed pressure relief  
valve. Verify that the pressure relief valve complies with local codes. If the pressure relief  
valve does not comply with local codes, replace it with one that does. Follow the installation  
instructions in the following paragraph.  
Install a discharge line so that water discharged from the pressure relief valve will exit within  
six (6) inches (15.2 cm) above, or any distance below the structural floor and cannot contact  
any live electrical part. The discharge line is to be installed to allow for complete drainage of  
both the combination temperature and pressure relief valve and the discharge line. The  
discharge opening must not be subjected to blockage or freezing. DO NOT thread, plug or  
cap the discharge line. It is recommended that a minimum clearance of four (4) inches (10.2  
cm) be provided on the side of the water heater for servicing and maintenance of the  
pressure relief valve.  
DO NOT place a valve between the pressure relief valve and the hot water outlet!

SECTION V: VENTING  
WARNING  
The venting system must be properly installed. Failure to properly install the vent system could  
result in property damage, personal injury, or death.  
Do not install damaged venting system components. If damage is evident, please contact the  
supplier where the water heater was purchased or the venting manufacturer for replacement parts.  
Use only the vent terminals and vent/air intake pipe components listed in this manual. Do not use  
other vent/air intake components not certified for the water heater.  
The water heater requires its own separate venting system. Do not connect the exhaust vent into an  
existing vent pipe or chimney.  
Make sure all pipe connections are firmly pressed together so that the gaskets make a tight seal.  
All of the exhaust venting connections must be leak checked with a soap solution upon initial start up  
of the water heater. Any leaks must be repaired before continuing operation of the water heater.  
Do not terminate the venting where noise from the exhaust or intake will be objectionable. This  
includes locations close to or across from windows and doors. Avoid anchoring the vent and intake  
pipes directly to framed walls, floors, or ceilings unless rubber isolation pipe hangers are used. This  
prevents any vibrations from being transmitted into the living spaces.  
Do not exceed the venting distances or the number of elbows listed in this manual. Exceeding the  
maximum venting distances may cause the water heater to malfunction or cause an unsafe  
condition.  
CAUTION  
The vent must terminate a minimum of 12 inches above expected snowfall level to prevent blockage  
of the vent termination.  
NOTICE  
Before beginning installation of any vent pipe components, read the vent pipe manufacturer’s  
installation instructions.  
The water heater must be protected from freezing downdrafts or drained during shutdown periods.  
Provide protection for the building materials from degradation caused by flue gases from the exhaust  
vent terminal.  
22  
Download from Www.Somanuals.com. All Manuals Search And Download.  
VENTING  
The venting instructions must be followed to avoid restricted combustion or recirculation of flue gases.  
Such conditions cause sooting or risks of fire and asphyxiation.  
Models TGHE-160I-N(X) and TGHE-199I-N(X) are a direct vent design with a single coaxial vent tube in  
which the flue products are discharged to the outdoors through the center flue tube and combustion air  
from outdoors is taken through the outside intake air pipe surrounding the center flue exhaust pipe.  
All venting components must be ordered separately from the supplier of this water heater or through the  
suppliers listed in this manual. These water heaters must use the venting components designed for  
EverHotTGHE series water heaters. The standard horizontal vent kit available for this water heater  
consists of one 90horizontal discharge adapter and one horizontal vent termination kit. These  
components are suitable for mounting the water heater on an outside wall. If longer venting distances are  
required, additional venting components are available from the supplier of the suppliers listed in this  
manual.

Each 90º elbow is equivalent to 6 ft (1.8 m) in straight vent pipe length. Each 45 degree elbow is  
equivalent to 3 ft (0.9 m) in straight pipe length. The total maximum equivalent vent pipe distance  
cannot exceed 41 feet (12.5 m).  
VENTING SYSTEM LAYOUT  
Refer to the preceding illustration and location requirements for location of the vent terminal and also  
local and state codes. In the absence of local codes, refer to the latest edition of the National Fuel Gas  
Code ANSI Z223.1/NFPA 54 (latest edition) or Canadian Installation Codes CAN/CGA-B149 (latest  
edition). Keep the venting system as short as possible and keep the number of elbows used to a  
minimum. The water heater may be vented directly through the wall (horizontally) or vertically through the  
roof. In all cases, the maximum equivalent length of vent pipe allowed is 41 feet (12.5 m). To calculate  
the total equivalent feet of vent pipe use the following formula:  
D = L + (EL90 x 6) + (EL 45 x 3)  
D = L + (EL90 x 1.8) + (EL45 x 0.9)  
For Length in Feet  
For Length in Meters  
D = Total Equivalent Length of Venting System  
L = Length of Straight Section of Vent / Air Intake Pipe (in feet)  
EL90 = Number of 90º Elbows.  
EL45 = Number of 45º Elbows  
The venting table above provides examples of maximum venting distances with various elbow  
combinations.  
The Bradford White EverHotTGHE model series has dedicated venting system components, which  
must be ordered separately. Review the “Venting System Installation Instructions” and the venting  
components later in this manual to determine the venting system layout and parts required. A Standard  
Vent Kit is available for outside through the wall venting installations. The Standard Vent Kit consists of:  
one 90discharge adapter and one horizontal vent termination kit. If this type of vent installation is not  
possible, contact a venting supplier listed in this manual for additional venting components illustrated at  
the back of this instruction manual.  
VENTING SYSTEM INSTALLATION  
Reference the preceding section and venting components illustrations at the end of this manual to  
determine the parts required for your particular venting system installation. The required venting  
component parts are available from the suppliers listed in this manual. Use the Venting System

Prior to the Installation of the EverHotDirect Vent System  
The EverHot TGHE series water heaters have two adjustable wall mounting support brackets fitted on the  
top and bottom of the water heater casing. When installing a “Standard Vent Discharge Kit” to vent  
directly out the wall to the back of the water heater, these brackets should be adjusted so that the water  
heater is moved out the maximum 2” (5.1 cm) away from the wall. Before cutting the vent terminal to the  
required length, ensure that the distance the water heater is away from the wall has been accounted for.  
Horizontal Direct Vent Installations  
Whenever possible, install the EverHot TGHE series water heater on or near an outside wall for the  
shortest vent with the least number of elbows. The standard vent kit available for this water heater  
consists of one 90vent discharge adapter and a horizontal vent termination kit. This kit is for venting  
directly through an outside wall.  
Figure 9. Standard Vent Kit – Horizontal Direct Vent Installations  
For installations on interior walls, venting components may be purchased from the venting suppliers listed  
in this manual to extend the venting distance using extension tubes and elbows. Use the formula and  
venting table shown previously in this manual to calculate the total equivalent distance of vent pipe. Do  
not exceed the maximum of 41 equivalent feet (12.5 m). Refer to the parts list at the end of this manual,  
as well as the Venting System Installation Instructions supplied with the venting for available venting  
components and detailed instructions on fitting the components together.

Combustion Blower Dip Switch Settings  
To assure optimum efficiency and reduced noise levels, the combustion blower switch has two dip switch  
settings. Dip switch number 1, the top dip switch, is shipped from the factory set to the ON position to  
compensate for the maximum vent/air intake length.  
Depending upon the vent/air intake length of the installation, dip switch number 1 may need to be  
adjusted to compensate for the venting system distance.  
When the equivalent length of vent pipe, D, is less than 21 feet (6.4 m), move dip switch number 1 to the  
OFF position.  
When the equivalent length of vent pipe, D, is 21 feet (6.4 m) or more, leave dip switch number 1 in the  
ON position.  
Dip switch number 1 is located in the top row of dip switches, 1 through 8 on the PC board. See the  
following diagram to identify the correct switch. If you do not understand the information concerning the  
dip switch settings or the location of the dip switch, contact Bradford White Sales (800-532-4020) or  
Technical Service (800-334-3393) for assistance. Use the following examples and the previous  
discussion on calculating the equivalent vent length to determine the correct setting for dip switch number  
1.  
Example #1:  
You have 6 feet (1.83 m) of vent pipe and one 90elbow.  
D = 6 + (1 x 6) + (0 x 3)  
D = 12 feet of equivalent vent pipe  
Dip switch number 1 should be moved to OFF position.  
Example #2:  
You have 15 feet (4.57 m) of vent pipe and two 90elbows.  
Figure 12. Dip Switch  
Settings.  
D = 15 + (2 x 6) + (0 x 3)  
D = 27 feet of equivalent vent pipe  
Leave dip switch number 1 in the ON position (default setting).  
WARNING  
Do not alter dip switch number 1 before using the formula and venting charts to determine the  
equivalent vent length. All other dip switches with the exception of dip switch number 1, shown in  
the illustration, MUST NOT be altered unless instructed to do so. Unauthorized adjustments can  
cause property damage, personal injury, scalding, or death.

Installation of Venting System Components  
WARNING  
When installing the EverHotTGHE model series direct vent water heaters, use only EverHot  
vent/air intake system kits and components approved for use with the water heater. Installation  
and service must be performed by a qualified installer, service agency, or the gas supplier.  
Installation must meet all state and local codes regarding installation and location of vent systems  
for direct vent appliances. In the absence of local codes, the National Fuel Gas Code, ANSI  
Z223.1/NFPA 54 (latest edition) and/or CSA B149.1 (latest edition), Natural Gas and Propane  
Installation Code must be followed. The maximum vent length, as stated in the in this manual,  
should never be exceeded. Follow the instructions below and all instructions located in this manual  
when installing a vent pipe system. Improper installation of vent piping, or failure to follow all  
installation instructions completely, can result in property damage, and/or death.  
WARNING  
Refer to the Bradford White EverHot TGHE series water heater Installation and Operation Instruction  
Manual for details concerning vent system termination positions/clearances, allowable vent pipe  
lengths, and in what position dip switch number 1 should be placed. If you do not understand how to  
configure your vent pipe system and/or which position dip switch number 1 should be placed in,  
please contact your Bradford White supplier for assistance.  
WARNING  
Make sure all the pipe connections are firmly pressed together so that the gaskets form a tight seal.  
NOTICE  
When mounting the water heater on an outside wall, be sure the vent/air intake pipe will exit  
between the wall studs. DO NOT cut through the wall studs for the vent/air intake pipe opening.  
WARNING  
Before installation inspect each vent component for damage and correct seal placement. Do not  
attempt to fix or install any damaged vent components.  
CAUTION  
Failure to properly support the vent piping with hangers and clamps may result in damage to the  
water heater or venting system.  
Vertical venting must be supported every 5 feet of vertical run and horizontal venting must be  
supported every 3 feet of horizontal run of vent pipe length.

Condensate  
The TGHE series water heaters are factory equipped with a condensate trap and drain line. All  
condensate must drain and be disposed of per local codes. Use only vent that is approved venting; do  
not use PVC, CPVC, ABS, or galvanized material to vent this appliance.  
If the condensate drain gets blocked, an error code will display on the controller. If this occurs, the  
condensate drain must be cleaned. The condensate trap will automatically prime during operation of the  
unit as condensate forms. Condensate draining from the unit indicates that the trap is full and that there  
is no blockage in the condensate drain.  
Use only PVC or CPVC pipe for the condensate drain line. The drain pipe, along its entire length, must  
be at least the same diameter as the drain line (1/2” NPT). The drain pipe must be as short as possible  
and have a downward pitch. The end of the drain pipe must be open to the atmosphere. The end must  
not be underwater or other substances. Do not connect the drain pipe directly to the rain sewer. Do not  
connect the condensate drain line with an air conditioning evaporator coil drain.  
To minimize freezing of the condensate, run the condensate drain line through an interior wall or between  
insulation and an interior wall.  
CAUTION  
Do not plug or cap the integrated condensate line. Without proper drainage or disposal, condensate  
will damage the water heater.  
Recommended Vent/Air Intake Terminal Position  
Terminals should be so positioned as to avoid products of combustion entering openings into buildings or  
other flues or vents.

Shortening of Vent Extensions  
Figure 16. Illustration Showing How to Shorten Vent Extensions.  
The polypropylene (PP) inside pipe should always extend 0.4 in. (10 mm) beyond the white plastic  
outside pipe on the male end of the vent extension. Always cut the male end of the vent pipe extension.  
Do not attempt to cut the female end.  
Figure 17. Illustration Showing How to Determine the Length to Cut Off.  
Pipes overlap by 2.5 in. (65 mm). Therefore, when cutting to size, add 2.5 in. (65 mm) to the extension  
pipe length (X) needed for installation. Deburr all sharp edges. Otherwise, the gaskets may get  
damaged, which can result in the vent system no longer being air tight.  
WARNING  
Improper installations of vent system and components, or failure to follow all installation instructions,  
can result in property damage or serious injury.

SECTION VI: GAS CONNECTIONS  
WARNING  
Connect this water heater only to the type of gas as shown on the rating plate. Use clean black iron  
pipe or equivalent material approved by local codes and ordinances. Dirt and scale from the pipe  
can enter the gas valve and cause it to malfunction. The inlet gas line must have at least a 3 in.  
(7.62 cm) drip leg (sediment trap) installed as close to the water heater’s gas valve as possible. A  
ground joint union must be installed in the gas supply line, as close to the water heater as possible,  
to permit servicing of the water heater. Compounds used on the threaded joints of the gas piping  
must be resistant to the action of liquefied petroleum gases/propane gas. DO NOT apply pipe dope  
to the gas valve inlet, and make certain that no pipe dope has become lodged in the inlet screen of  
the gas valve. Extreme care must be taken to ensure no pipe dope enters the gas valve and to  
avoid excessive torque when tightening the gas supply line to the gas valve. Excessive torque may  
result in cracking of the gas valve housing. The suggested maximum torque is 31.5 ft-lbs. (4.4 kg-  
m). The manufacturer of this water heater will not be liable for any damage or injury caused as a  
result of a cracked gas inlet as a result of excessive torque.  
This water heater and its gas connection must be leak tested before placing the water heater in  
operation. Check for gas leaks with a soap and water solution and a brush or a commercial leak  
detector fluid. NEVER USE A MATCH OR OPEN FLAME FOR TESTING!  
The water heater is not intended for operation at higher than 10.5 inches water column for natural  
gas or 13.5 inches water column for L.P. supply gas pressure. Higher gas supply pressures require  
supplemental reducing service regulation. Exposure to higher gas supply pressure may cause  
damage to the gas controls, which could result in fire or explosion. If overpressure has occurred,  
such as through improper testing of gas lines or emergency malfunction of the supply system, the  
gas valve must be checked for safe operation. Make sure that the outside vents on the supply  
regulators and the safety vent valves are protected against blockage. These are parts of the gas  
supply system, not the water heater.  
WARNING  
Conversion of this unit from natural gas to L.P. or L.P. to natural gas CANNOT be done in the field.  
If the gas supply does not match the type shown on the water heater rating plate, then contact your  
supplier for the proper water heater for the building gas supply.  
CAUTION  
The water heater and individual shut-off valve must be disconnected from the gas supply piping  
system during any pressure testing of the system at test pressures in excess of ½ psi (3.5 kPa).  
The water heater must be isolated from the gas supply piping system by closing its manual shutoff  
valve during any pressure testing of the gas supply system at test pressures equal to or less than ½  
psi (3.5 kPa). The supply line must be capped when not connected to the water heater.  
If copper supply lines are used, they must be internally tinned and certified for gas service.  
The gas supply lines must meet all requirements of the National Fuel Gas Code ANSI Z223.1-Latest  
Edition, or in Canada Natural Gas Installation Code CAN/CGA B149.1-Latest Edition or Propane  
Installation Code CAN/CGA B149.2-Latest Edition. The gas supply line may need to be larger for  
EverHotwater heaters than a storage water heater in the case of a replacement installation. Refer to  
the piping capacity tables at the end of Section VI, “Gas Connections” and in the codes referenced above.  
A 3 in. (7.6 cm) drip leg (sediment trap) is required ahead of the gas inlet connection to the water heater.  
Install a manual gas shut-off valve before the gas inlet connection to the water heater before connecting  
to the gas line. A union should be installed before the water heater gas connection for disconnection for  
servicing.  
43  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Check the type of gas and the gas inlet pressure before connecting the EverHot® water heater to the gas  
supply. If the gas supply type does not match the type shown on the water heater rating plate, then DO  
NOT connect the water heater. Contact your Bradford White supplier for the correct water heater.  
GAS METER SIZE – NATURAL GAS ONLY  
Be sure that the gas meter has sufficient capacity to supply the full rated gas input of the water heater, as  
well as the requirements of all other gas fired equipment supplied by the meter. If the gas meter is too  
small, ask the gas company to install a larger meter having adequate capacity.  
GAS PRESSURE REGULATION  
Minimum and maximum gas supply pressures are listed below: The minimum gas pressure specified  
below is required for the full input rating specified on the water heater rating plate.  
Natural Gas: Minimum: 5.0 in. w.c.  
L.P. Gas:  
Minimum: 8.0 in. w.c.  
Maximum: 13.5 in. w.c.  
Maximum: 10.5 in. w.c.  
Before placing the WATER heater in operation, check for gas leakage. Use soap and water solution or  
other material acceptable for the purpose of locating gas leaks.  
WARNING  
DO NOT use matches, candles, flame, or other sources of ignition for this purpose.

INITIAL OPERATION AND TESTING (INSTALLER ONLY)  
1. Open the gas and water supply valves to the water heater.  
2. Check for water and gas leaks. Use soap solution to check for gas leaks.  
3. To check inlet supply pressure, remove the 1/8” NPT plug on the gas inlet supply fitting just below  
the bottom casing and install a barb fitting for attaching a hose to a manometer. For checking the  
gas manifold pressure, the plug is located just below the gas manifold connection inside the  
control panel.  
4. Turn power on (after completing electrical connections – refer to Section VII, “Electrical  
Connections”) and fully open a hot water tap.  
5. Measure the gas pressures to see that these are within the specified limits below:  
Supply Pressure:  
Manifold Pressure:  
Nat. Gas: Min.: 5 in. w.c., Max.: 10.5 in. w.c.  
L.P. Gas: Min.: 8 in. w.c., Max: 13.5 in. w.c.  
Nat. Gas: 2.4-3.0 in. w.c. High Fire, 0.7-0.85 in. w.c. Low Fire  
L.P. Gas: 3.6-4.0 in. w.c. High Fire, 1.06-1.46 in. w.c. Low Fire  
(Manifold pressures vary depending on the water heater model)  
6. Turn off the hot water faucets. Disconnect the electrical power to the water heater. Remove the  
pressure gauges and replace the plugs. Check for gas leaks around the plugs.  
7. Replace the front control panel. Restore electrical power to the water heater  
NOTICE  
If the gas supply pressure is below the specified value, check the gas piping to ensure that it is the  
correct size for all the gas appliances on line. Check the supply pressure with all the gas appliances  
in operation. The manifold pressure will vary with the water flow rate. Several hot water faucets  
may need to be opened with the temperature control set on the highest setting in order to get  
maximum high fire manifold pressure. If the manifold pressure is below the specified value and  
there is sufficient water pressure and flow, be sure the inlet gas pressure is within the specified limits  
before attempting to adjust the manifold pressure.

SECTION VII: ELECTRICAL CONNECTIONS  
WARNING  
Turn off or disconnect the electrical power supply to the water heater before servicing. Label all  
wires prior to disconnection when servicing controls. Wiring errors can cause improper and  
dangerous operation. Verify proper operation after servicing.  
All electrical wiring must be installed and grounded in accordance with local codes, or in the  
absence of local codes, the National Electrical Code, ANSI/NFPA 70 (latest edition) and/or CSA  
C22.2 Electrical Code (latest edition).  
The water heater must be wired to a 120 VAC, 60 Hz, 15A power supply. The water heater should be  
connected to a GFI outlet and wired on a separate circuit and breaker. A strain relief will be required for  
the line cord. Do not plug the line cord into a receptacle that can have the power supply interrupted by a  
switch that is used to control lights or another appliance.  
If wiring in conduit is required, install an electrical conduit connector. A disconnect switch should be  
provided near the water heater for servicing. Connect the wires exactly as shown in the wiring diagram of  
this manual and on the inside cover panel. The black wire is the hot leg; the white wire is neutral. A  
green screw is provided in the junction box for the green wire ground connection.  
CAUTION  
Do not energize the electric circuit before the water heater tank is filled with water.

TEMPERATURE CONTROLS  
The front panel temperature control allows the end user to set the hot water supply temperature and will  
display certain diagnostic codes of the water heater if there is a malfunction. All models have the option  
of up to four controllers that can be used to conveniently control water temperatures for bath and shower  
fixtures.  
The main control is integrally mounted to project through the front panel of the water heater. The  
adjustment range is 98-120F. Additional remote controls can be purchased, p/n 239-48788-00, and  
these have the same available temperature range as the main control. If an optional commercial control,  
p/n 239-48789-00, is purchased, the allowable temperature can be up to 185ºF. If a commercial control is  
used, this reduces the warranty period of the water heater. Also, if a commercial control is used with a  
water heater, all of the remaining controls connected to the water heater can achieve the maximum  
temperature that the commercial control allows. See Table 13 for more details.

* Re-setting the Maximum Temperature  
These units have a default maximum temperature of 120º F (49º C) and an option to increase the maximum  
temperature to 140 ºF (60 ºC). Temperature settings from 125-140 ºF (52-60 ºC) are available by setting dip switch 6  
to ON in the SW1 bank of 8 dip switches.  
**239-48789-00, Commercial Control  
These settings require the 239-48789-00 controller. When the 239-48789-00 controller is connected, these higher  
temperatures are available on all controller models in the system. Use of a 239-48789-00 controller in a residential  
dwelling will reduce the warranty coverage to that of a commercial warranty application.  
DANGER  
Hotter water increases the risk of scald injury. Scalding may occur within 5 seconds at a  
temperature setting of 140F (60C). To protect against hot water injury, install a mixing valve in the  
water system. This valve will reduce point of discharge temperature by mixing cold and hot water in  
branch water lines. A licensed plumbing professional or local plumbing authority should be  
consulted.  
CAUTION  
This water heater, when set at a lower temperature setting is not capable of producing hot water of  
sufficient temperature for sanitizing purposes. Always check water temperature by hand before  
entering the shower or bath. The temperature may have been changed. Test the temperature of  
the water with your hand or elbow before placing a child in the bath or shower. Do not leave a child  
or an infirm person in the bath unsupervised.

WARNING  
Do not adjust this water heater in any residential application above 120ºF. If this water heater is  
used in a commercial application where temperatures in excess of 120ºF are required, use an ASSE  
approved mixing device.  
WARNING  
This water heater is equipped with an energy cut out device to prevent overheating. Should  
overheating occur or the gas supply fails to shut off, turn off the manual gas control valve to the  
water heater, and call a qualified service agency.  
NOTICE  
The lower the temperature setting, the greater the energy efficiency to heat the water. Lower water  
temperatures also extend the heat exchanger life. Remember, no water heating system will provide  
exact temperatures at all times. Allow a few days of operation at this setting to determine the correct  
temperature setting consistent with the requirements for the installation.  
When multiple controls are used, depressing the Priority Button will override the main control and display  
the setpoint of the remote control in use. Both the remote controls and the main control will display  
diagnostic codes in the event the water heater needs service.  
NOTICE  
No more than four temperature controls may be connected to the EverHot® water heater.  
NOTICE  
The default temperature setting that will appear when the water heater is first connected to the electrical  
supply is 104ºF. In the event of a power interruption, the unit will retain its set temperature for up to 6  
hours. If the power is interrupted for more than 6 hours, the unit will revert back to a temperature of  
104°F.  
Before installing optional remote controls, determine the most convenient locations(s). When deciding on  
the best location for the remote controls, please consider the following items:  
1. Place the controls out of reach of small children.  
2. Avoid locations where the control(s) will become hot, such as over a radiator, register, or other  
heat sources.  
3. Avoid direct sunlight. The digital readout can be difficult to read in direct sunlight.  
4. Avoid areas where the remote can be splashed with cooking water, oil, or sauce.  
5. The remote control operates with low voltage.

heater. If the water heater was installed with drain solenoid freeze protection, the water  
heater will drain automatically when power is disconnected.  
TEMPERATURE ADJUSTMENT  
DANGER  
Hotter water increases the risk of scald injury. Scalding may occur within 5 seconds at a  
temperature setting of 140F (60C). To protect against hot water injury, install a mixing valve in the  
water system. This valve will reduce point of discharge temperature by mixing cold and hot water in  
branch water lines. A licensed plumbing professional or local plumbing authority should be  
consulted.  
CAUTION  
This water heater, when set at a lower temperature setting is not capable of producing hot water of  
sufficient temperature for sanitizing purposes. Always check water temperature by hand before  
entering the shower or bath. The temperature may have been changed.  
NOTICE  
This water heater is equipped with an energy cut out device to prevent overheating. Should  
overheating occur or the gas supply fails to shut off, turn off the manual gas control valve to the  
water heater and call a qualified service agent.  
NOTICE  
The lower the temperature setting, the greater the energy efficiency to heat the water. Lower water  
temperatures also extend the heat exchanger life. Remember, no water heating system will provide  
exact temperatures at all times. Allow a few days of operation at this setting to determine the correct  
temperature setting consistent with the requirements for the installation.  
1. The outlet water temperature of the EverHot water heaters is adjusted using the main control  
located on the front panel of the water heater (or optional remote controls). When a remote  
temperature control is installed, the temperature can only be adjusted on the control that has  
the Priority Indicator Light glowing. The temperature displayed on the control in use will also  
be displayed on all the other remote controls.  
58

2. To set the desired temperature on the control, all hot water faucets must be closed. If there  
are remote controls installed, press the “Priority” button on the control you want to change the  
setting on and the “Priority” indicator light will glow.  
3. Press the Up or Down button until the required temperature is displayed on the digital  
monitor. The default available water temperature range for the main control is 98-120ºF.  
4. To operate the water heater, simply turn any hot water tap on. This will automatically light the  
burner and provide hot water at the preset temperature. If the optional remote controls have  
been installed, the “IN USE” indicator light will glow on all remote controls.  
5. The control(s) can also display diagnostic codes, water flow rate through the unit (in gallons  
per minute), and the outlet water temperature.  
6. Press and hold the “On/Off” button for 2 seconds. While holding the “On/Off” button, press  
the “Up” button to display a sequence of up to 9 diagnostic codes, if any, stored in memory  
that has been experienced. Any diagnostic codes will be displayed on the digital monitor in  
sequence starting with the most recent code. To exit this mode, press the “On/Off” button  
and “Up” button as before.

SCALDING  
Figure 41. Scalding Warning.  
This water heater can deliver scalding temperature water at any faucet in the system. Be careful  
whenever using hot water to avoid scalding injury. Certain appliances, such as dishwashers and  
automatic clothes washers may require increased water temperature. By setting the thermostat on this  
water heater to obtain the increased temperature water required by these appliances, you may create the  
potential for scald injury. To protect against injury, you should install a tempering valve in the water  
system. This valve will reduce point of discharge temperature by mixing cold and hot water in branch  
supply lines. Such valves are available from the local plumbing supplier.  
CAUTION  
Test the temperature of the water with your elbow before placing a child in the bath or shower. Do not  
leave a child or an infirm person in the bath unsupervised.  
The following chart details the relationship of water temperature and time with regard to scald injury and  
may be used as a guide in determining the safest water temperature for your applications.

SECTION IX: MAINTENANCE  
WARNING  
Always turn off the electrical power supply, the manual gas valve, and the manual water control  
valve whenever servicing this appliance.  
KEEP THE WATER HEATER AREA CLEAR AND FREE FROM COMBUSTIBLE MATERIALS,  
GASOLINE, AND OTHER FLAMMABLE VAPORS AND LIQUIDS.  
The EverHotwater heater should be checked annually by a qualified technician. Regular maintenance  
will keep the water heater operating efficiently and help to assure reliable operation and a long service  
life.  
1. Remove and clean the inlet water filter screen. If a Y-type strainer or cartridge filter is used on  
the cold water inlet to the water heater, inspect or clean as needed to assure full water flow to the  
water heater.  
2. Visually inspect the burner flames. The flame must burn with a clear blue, stable flame (possibly  
with orange tips). Refer to Figure 42 for satisfactory flame appearance. If the burner flame  
appearance is not satisfactory or debris is visible on the burners, remove and clean with a  
vacuum cleaner.  
Figure 42. Burner Flame Appearance.  
3. Inspect entire venting system and vent terminal. Make sure all the venting connections are tight  
and the gaskets are in good condition. Check the vent terminal openings for blockage and clean,  
if necessary. Keep shrubs and vegetation clear of the vent terminal.  
4. All electric motors are permanently lubricated and do not need oiling. Remove the combustion air  
blower and clean wheel and housing with soft brush or vacuum.  
5. If the “LC” code has been flashing on the display, the heat exchanger will need flushing to remove  
lime and scale deposits. Refer to the “Flushing Procedure for Lime Scale Removal…” in Section  
IX, “Maintenance.”  
6. Check operation of the pressure relief valve. To check the relief valve, lift the lever at the end of  
the valve several times. The valve should seat properly and operate freely. If water does not  
flow, remove and inspect for obstructions or corrosion. Replace with a new valve of the  
recommended size as necessary. A thorough inspection of the valve should be performed at  
least every three years by removing the pressure relief valve from the outlet piping. Do not  
attempt to repair the valve, as this could result in improper operation and explosion of the heat  
exchanger and piping. In areas with poor water conditions, it may be necessary to inspect the  
pressure relief valve more often than the recommended maintenance schedule.  
64  
Download from Www.Somanuals.com. All Manuals Search And Download.  
CAUTION  
Before manually operating the valve, make sure that a drain line has been attached to the valve to  
direct the discharge to an open drain. Failure to take this precaution could mean contact with  
extremely hot water passing out the valve during this checking operation.  
FLUSHING PROCEDURE FOR MINERAL SCALE REMOVAL FROM HEAT EXCHANGER  
The amount of calcium carbonate (minerals) released from water is in direct proportion to water  
temperature and usage. The higher the water temperature or water usage and the harder the water  
(more dissolved calcium carbonate), the more mineral deposits are dropped out of the water. This is the  
mineral scale that forms in pipes, water heaters, and on cooking utensils.  
Mineral accumulation reduces the efficiency and longevity of the heat exchanger coil and will cause the  
water heater to malfunction. The mineral scale may need to be periodically removed from the heat  
exchanger (indicated by the “LC” code on the remote display). The usage of water softening equipment  
greatly reduces the hardness of the water. However, this equipment does not always remove all of the  
hardness (minerals). The heat exchanger may occasionally need to be flushed to clear out the mineral  
deposits. Use the following procedure and Figure 43 to flush the heat exchanger and remove the mineral  
scale.  
1. Disconnect power to the water heater.  
2. Close the shut-off valves in the cold water inlet and outlet supply (V3 and V4).  
3. Connect pump outlet hose (H1) to the cold water line at valve (V2). Connect drain hose (H3) to  
valve (V1).  
4. Pour 4 gallons of virgin, food grade, white vinegar or citric acid into a 5 gallon bucket.  
5. Place the drain hose (H3) and the hose (H2) to the pump inlet into the cleaning solution.  
6. Open the both valves (V1 and V2) to the hot and cold water lines.  
7. Turn on power to the circulating pump and allow the vinegar to circulate through the heat  
exchanger coil for at least 45 minutes. Heat exchangers containing a considerable amount of  
minerals may require several hours.

Common Troubleshooting Comments on the Operation of the EverHot® Tankless Water Heater  
Comment: I don’t have any hot water when I open the tap!  
Make sure the gas and electricity is turned on to the water heater. The temperature display should have  
the green light lit when a hot water tap is open and the water heater is operating. Make sure there are no  
diagnostic codes flashing on the display.  
Comment: When I was using the hot water, the water got cold!  
If you reduced the hot water flow from the tap, you may have reduced the flow below the minimum flow to  
operate the water heater. If you mix the hot water with cold water at the tap in an attempt to get a  
temperature below the temperature being produced by the water heater, the hot water flow through the  
water heater may drop below the minimum flow required to operate the water heater. To remedy this  
situation, increase the total water flow from the tap or using the control decrease the setpoint temperature  
of the water heater to the temperature desired at the tap.  
Comment: White smoke comes out of the exhaust!  
During colder weather when the exhaust temperature is much hotter than the ambient air, the moist  
exhaust gases condense producing a white vapor cloud.  
Comment: When I open a hot water faucet I do not immediately get hot water!  
Hot water must travel through the plumbing piping to the faucet. This may take from 10 to 30 seconds  
depending upon the length of cold plumbing pipe the water must travel through.  
Comment: After I turn off the hot water tap, the fan on the water heater continues to run!  
The fan is designed to continue to run for a short time after the flow of water stops. This is to ensure  
constant water temperature during frequent short water draws (such as washing dishes), as well as  
exhausting residual heat and flue gases from the water heater and venting system.

SECTION XI: WARRANTY  
What does this Limited Warranty Cover?  
This limited warranty covers both the heat exchanger and component parts for leakage or other  
malfunction caused by defects in materials and/or workmanship. It applies to the original consumer  
purchaser and to any subsequent owner as long as the water heater remains installed at its original place  
of installation.  
What does this limited warranty not cover?  
This limited warranty does not cover leakage or other malfunction caused by:  
a) Defective installation, reinstallation at another location and specifically, any installation which is  
made in violation of applicable state or local plumbing, housing or building codes, or without a  
certified American Gas Association, ASME, or comparable combination temperature and  
pressure relief valve, or contrary to the written instructions furnished with the unit.  
b) Adverse local conditions, and specifically sediment or lime precipitate in the heat exchanger;  
corrosive elements in the atmosphere; or water quality contrary to the written requirements  
furnished with the unit.  
c) Misuse, and specifically operations and/or maintenance contrary to the written instructions  
furnished with the unit, removal of anode(s), disconnection, alteration or addition on non-  
approved components or apparatus, operation at settings other than those set forth on the rating  
plate, or accidental or other exterior damage.  
This warranty also does not cover:  
a) Production of noise, taste, odors, discoloration or rusty water.  
b) Incidental property damage, loss of use, inconvenience or other incidental or consequential costs.  
c) Costs associated with the replacement and/or repair of the unit, including any freight, shipping or  
delivery charges, any removal, installation or re-installation charges, any material, and/or permits  
required for installation, re-installation or repair, or charges to return the defective heater and/or  
component part to the manufacturer.  
What is the duration of the implied warranty?  
Any implied warranties, including the warranty of merchantability imposed on the sale of the water heater  
under the laws of the state of sale are limited in duration to one year from date of original installation.  
How does state law relate to the warranty?  
Some states do not allow:  
a) Limitations on how long an implied warranty lasts.  
b) Limitations on incidental or consequential damages.  
So the above limitations or exclusions may not apply to you.  
This warranty gives you specific legal rights, and you may also have other rights which vary from state to  
state.  
What is the period of coverage?  
This limited warranty runs from the date of installation (or without proof of installation, from three (3)  
months after the date of manufacture) for the period specified on the following chart.

Residential  
Applications  
Commercial and Radiant Heating  
Applications  
Heat Exchanger  
All other Parts and Components  
12-years*#  
5-years*#  
5-years*  
5-years*  
A warranty product or part is provided exclusive of labor, freight, and/or any installation costs. All  
replacement heaters and parts carry the balance of the original warranty, i.e. if an original twelve (12)  
year warranted heater develops a leak due to defects in materials/workmanship after only ten (10) years,  
the replacement unit is warranted for two (2) years in this example.  
*Note: Period of coverage is reduced to 3-years from date of purchase when used as a circulating water  
heater within a hot water circulation loop, where the water heater is in series with a circulation system and  
all circulating water flows through the water heater, and where an aquastat / thermostat, timer, or an on-  
76

demand recirculation is not incorporated. A system that incorporates a continuous recirculation due to  
timer settings, excessive heat loss of the loop or aquastat / thermostat setting will be treated as a  
continuous circulation system and have a reduced warranty of 3 years.  
On-demand recirculation is defined as a hot water re-circulating loop or system that utilizes existing hot  
and cold lines or a dedicated return line, and only activates when hot water is used. It can be activated  
by a push button, motion sensor, or voice activation but not by a temperature sensor. A timer added to a  
standard re-circulating pump is not considered as on-demand.  
# The warranty for a heat exchanger used in a circulation system which is controlled through an aquastat  
/ thermostat, or timer, or an on-demand system is 12 years for residential applications.  
Use of a Main Controller/Commercial control (p/n 239-48789-00) in a residential dwelling will reduce the  
warranty coverage to that of a commercial warranty application.  
What will we do to correct problems?  
If a defect occurs within the heat exchanger warranty period, we will:  
a) Provide a replacement water heater of our manufacture, (or at our option) repair any unit which  
develops a leak in the heat exchanger with the warranty period. To obtain a replacement water  
heater, you must forward both the rating plate from the defective unit to us and a copy of the  
original sales receipt. If government regulations require the replacement heater to have features  
not found in the defective heater, you will be required to pay the difference in price represented  
by those government required features.  
If a defect occurs within the parts warranty period, we will:  
a) Provide a replacement part (or at our option repair) any part which fails to function within the parts  
warranty period. To obtain a replacement, you must forward the defective part to us. If  
government regulations require the replacement part to have features not found in the defective  
part, you will be required to pay the difference in price represented by those government required  
features.  
What will we not do?  
We will not:  
a) Repair or replace any water heater, or part, subject to conditions outlined in “What does this  
limited warranty not cover?”  
b) Reimburse any costs associated with repair and/or replacement.  
c) Replace and/or repair any heater without complete model/serial number.  
d) Replace any water heater without prior receipt of actual rating plate from appliance and copy of  
original sales receipt.
