SECTION III: GENERAL INFORMATION  
FEATURES  
The Bradford White EVERHOT® IGE series tankless water heater is a high output, high efficiency  
appliance, which heats the water continuously as hot water is being drawn for use. Unlike tank type  
storage water heaters, this water heater does not store hot water. The burner operates whenever there is  
a demand for hot water and is off when the water flow stops. Hot water is continuously supplied for any  
length of time required, as long as the specified flow rates are not exceeded. There is no need to set the  
temperature higher than required for sufficient capacity. The EVERHOT water heater has sufficient  
capacity to supply several hot water faucets simultaneously. The hot water flow capability will be  
dependent upon the temperature of the outlet water selected. More detail can be found under the  
“Temperature Adjustment” section of this Installation and Operating Instruction Manual. Your plumbing  
professional should determine your hot water requirements before installing this water heater to be sure  
the capacity is sufficient for your application.  
The IGE series water heaters are designed to be installed outdoors on an outside wall. The  
water heater is compact (23 5/8” (60 cm) H x 13 3/4” (34.9 cm) W x 8 7/8” (22.6 cm) D) and  
mounts on an outside wall using the supplied wall bracket. No indoor space is needed and the  
water heater can be mounted at a height convenient for servicing.  
The weight is less than 50 pounds (23 kg) and can be installed by 1 person.  
The burners ignite within 3 seconds of water flow (1/2 gallon/minute (1.9 L/m) minimum) by direct  
spark ignition. There is no standing pilot.  
A variable speed combustion air blower forces the combustion air supply into the burner  
compartment.  
No venting system required. For outdoor installation only.  
An optional recess box is available which allows the water heater to be recessed into an outside  
wall and conceal the piping behind a cover for a more attractive installation. The box enclosure  
dimensions are: 40 ½” H x 14 ¾” W x 9 ½” D. Contact your Bradford White supplier to order this  
optional accessory.  
The burner flame is continuously monitored and modulated to match the heating requirements of  
the water flow. Temperature and flow sensors continually monitor the water flow and outlet water  
temperature and adjust the burner and combustion air blower to maintain temperature.  
The included, remote mount Main Control may be conveniently located near the point of use and  
is adjustable from 96-160°F for residential models (IGE-199R series), or 96-180°F for commercial  
models (IGE-199C series). In addition to the Main Control, up to two optional bathroom controls  
are available on the residential models for setting the temperature in the bathroom fixtures up to  
120°F.  
The Remote Main Control also displays fault codes if the water heater malfunctions to assist with  
servicing the water heater.  
The heat exchanger coil is provided with anti-freeze heaters for cold climate conditions for  
protection as low as -30°F (-34°C). Solenoids should be installed to drain the water heater in the  
event of a power failure.  
The water heater is very quiet in operation.

SECTION IV: 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 the outside building structure.

from the carton and remove all the contents.  
MOUNT WATER HEATER ON THE WALL  
The EVERHOT® IGE series water heater must be installed outdoors. Refer to Table 1  
clearances under overhangs, windows, doors, etc. Also avoid locations where there is heavy  
water runoff from roofs. Determine the proper height and location for the water heater to be  
installed. Consider the water and gas connections. Allow enough room for servicing the water  
heater and maintain the clearances from combustible materials previously stated. 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 or  
2x4 wooden support may be cut to span the wall studs and the brackets. Make sure the anchors  
are rated to support the 50 pound (23 kg) weight of the water heater.

Lime Condition Warning Signal:  
If the EVERHOT water heater is operated under hard water conditions without a water conditioner, the  
error code “LC” may flash on the remote temperature display. This code means the heat exchanger coil  
is beginning to accumulate scale deposits and MUST be flushed (see Section IX, “Flushing Procedure for  
Lime 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 reoccurring.  
NOTICE  
Failure to flush the appliance when “LC” is flashing will cause damage to the heat exchanger. Damage  
caused by lime or 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  
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.  
12  
Download from Www.Somanuals.com. All Manuals Search And Download.  
2. In order to service the water heater in the event the heat exchanger needs to be flushed from lime  
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 piping diagrams (fig. 2-5) at the end of Section V.  
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 (fig. 2-5) and the warning for the Pressure Relief Valve at  
the end of Section V on 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 “Recommended Piping for Power  
Failure Freeze Protection” (fig. 3) at the end of this Water Connections Section 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 of 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 installation. DO NOT operate the water heater without the filter in place.  
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. Refer to the suggested piping diagrams (fig. 4-5) at the  
end of Section V on Water Connections to be used as a guide.  
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 part# 239-44511-00 for the electronic  
manifold control for the first and second water heater and part# 239-44512-00 for the wiring  
harness for each additional water heater to be controlled. Instructions are included with these  
parts. Use the piping diagram in figure 5 in Section V as a guide.  
NOTICE  
Take care when using pipe dope or Teflon tape to avoid clogging the inlet screen and water flow  
sensor. Wipe off excess pipe dope from threads before connecting to the water heater.  
Commercial dishwashers will require either more than one water heater or a storage tank to supply a  
sufficient volume of hot water.

Recommended Piping for Power Failure Freeze Protection  
As long as electrical power and gas are supplied to the EVERHOT® water heater, freeze protection is  
provided to the heat exchanger and piping inside the water heater with ambient temperatures as cold as -  
30°F (-34°C), when protected from direct wind exposure. In the event of a power failure at 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 terminals  
provide on the PCB board. 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 ¼” 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.  
Drain Solenoid Piping (Fig. 3)  
CAUTION  
All piping located outside the building must be insulated and wrapped with heat tape to prevent freezing.

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 above on this page  
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 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 inch (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 foot 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,  
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 shutoff 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 CAN/CGA B149.1 Natural Gas Installation Code (Latest Edition) or CAN/CGA  
B149.2 Propane Installation Code (Latest Edition). The gas supply line may need to be larger for the  
EVERHOT® water heaters than a storage water heater in the case of a replacement installation. Refer to  
the gas piping capacity tables at the end of Section VI (Gas Connections) and in the codes referenced  
above.  
A 3” (7.6 cm) drip leg (sediment trap) is required ahead of the gas inlet connection to the water heater.  
See water heater installation illustration. Install a manual gas shutoff 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. Refer to the piping diagrams (Fig. 2-5) in  
Section V, “Water Connections”.  
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.

This water heater is equipped with an energy cut out device to prevent overheating. Should overheating  
occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance 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.  
Residential Models (see Figure 6):  
1. The outlet water temperature of the EVERHOT water heaters is adjusted using the Remote Main  
Control supplied in the water heater carton. When a Bath or Secondary Bath Control is installed,  
the temperature can only be adjusted on the remote 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.

SCALDING  
CAUTION  
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.  
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 temperature water. 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.  
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 APPLIANCE AREA CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE,  
AND OTHER FLAMMABLE VAPORS AND LIQUIDS  
Do not block the air inlet openings on the front panel or flue exhaust vent. These openings must be kept  
free of debris or obstructions for combustion air supply to the burners.  
The EVERHOT® water 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.  
2. Visually inspect the burner flames. The flame must burn with a clear blue, stable flame. Refer to  
Figure 10, “Burner Flame Appearance” 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.  
3. Check the front vent outlet for any obstructions.  
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 remote display, the heat exchanger will need flushing to  
remove lime and scale deposits. Refer to the “Flushing Procedure for Lime Scale Removal From  
Heat Exchanger” procedure in the Maintenance Section.  
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.

Burner Flame Appearance (Fig 10)  
WARNING  
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 LIME SCALE REMOVAL FROM HEAT EXCHANGER  
The amount of calcium carbonate (lime) 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 lime deposits are dropped out of the water. This is the lime scale that forms  
in pipes, water heaters and on cooking utensils.  
Lime accumulation reduces the efficiency and longevity of the heat exchanger coil and will cause the  
water heater to malfunction. The lime 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 (lime). The heat exchanger may occasionally need to be flushed to clear out the lime deposits.  
Use the following procedure and diagram (fig. 11) to flush the heat exchanger and remove the lime scale.  
1. Disconnect power to the water heater.  
2. Close valves in the cold water inlet and outlet supply.  
3. Connect PVC hoses (may use garden hose to the drain valve outlet fittings). Connect a circulator  
pump to the hose connected to the cold water inlet. See figure 11 for hose and circulator  
connections.  
4. Pour 4 gallons of fresh vinegar into a 5 gallon bucket.  
5. Place the ends of the hose into the bucket.  
6. Open the drain valves to the hose fittings.  
7. Turn on power to the circulating pump and allow the vinegar to circulate through the heat  
exchanger coil for at least 45 minutes. Heavily limed heat exchangers may require several hours.  
8. Turn off power to the circulating pump.  
9. Run hose from hot water outlet to a drain.

10. Close the drain valve on the cold water inlet. Leave hot water drain valve open. Open cold water  
inlet to flush with fresh water.  
11. Allow water to flow out of the hose for 5 minutes to flush vinegar from the water heater.  
12. Shut off cold water inlet valve. Remove filter screen and clean out any sediment. Reinstall.  
13. Close the hot water drain valve. Open the cold water inlet and hot water supply valves.  
14. Disconnect the hoses from the drain valve connections.  
15. Restore power to the water heater and check operation.

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 remote 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 error 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, either increase the total water flow from the tap or using the remote temperature controller,  
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 65 seconds 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.
