This appliance has been design certified as complying withAmerican
National Standard for water heaters and is considered suitable for:
HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated to a
temperature which will satisfy space heating, clothes washing, dish
washing, and other sanitizing needs can scald and permanently injure
you upon contact. Some people are more likely to be permanently
injured by hot water than others. These include the elderly, children,
the infirm, or physically/mentally handicapped. If anyone using hot
water in your home fits into one of these groups or if there is a local
code or state law requiring a certain temperature water at the hot
water tap, then you must take special precautions. In addition to
using the lowest possible temperature setting that satisfies your
hot water needs, a means such as a Mixing Valve should be used
at the hot water taps used by these people or at the water heater.
Mixing valves are available at plumbing supply or hardware stores.
Consult a Qualified Installer or Service Agency. Follow mixing valve
manufacturer’s instructions for installation of the valves. Before
changing the factory setting on the thermostat, read the “Temperature
Regulation” section in this manual, see Figure 21.

locatInG the new water heater
facts to consIder aBout the locatIon
Carefully choose an indoor location for the new water heater, because
the placement is a very important consideration for the safety of the
occupants in the building and for the most economical use of the
appliance. this water heater is not for use in manufactured
(mobile) homes or outdoor installation.
Whether replacing an old water heater or putting the water heater in
a new location, the following critical points must be observed:
1. Select a location indoors as close as practical to the vent terminal or
location to which the water heater vent piping is going to be connected,
and as centralized with the water piping system as possible.
2. Selected location must provide adequate clearances for servicing
and proper operation of the water heater.
Installation of the water heater must be accomplished in such a manner
that if the tank or any connections should leak, the flow will not cause
damage to the structure. For this reason, it is not advisable to install
the water heater in an attic or upper floor. When such locations cannot
be avoided, a suitable metal drain pan should be installed under the
water heater. Drain pans are available at your local hardware store.
Such a drain pan must have a clearance of at least 1.0” (2.5cm)
greater than any point on the water heater’s outer jacket and must
be piped to an adequate drain. The pan must not restrict combustion
air flow. For example, if a circular pan is used, it must be a minimum
of 27” (69cm) in diameter, see Figure 1.
Water heater life depends upon water quality, water pressure and
the environment in which the water heater is installed. Water heaters are
sometimes installed in locations where leakage may result in property
damage, even with the use of a drain pan piped to a drain. However,
unanticipated damage can be reduced or prevented by a leak detector or
water shut-off device used in conjunction with a piped drain pan. These
devices are available from some plumbing supply wholesalers and
retailers, and detect and react to leakage in various ways:
• Sensors mounted in the drain pan that trigger an alarm or turn off the
incoming water to the water heater when leakage is detected.
• Sensors mounted in the drain pan that turn off the water supply to
the entire home when water is detected in the drain pan.
• Water supply shut-off devices that activate based on the water
pressure differential between the cold water and hot water pipes
connected to the water heater.
• Devices that will turn off the gas supply to a gas water heater while
at the same time shutting off its water supply.
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS
(VAPORS) ARE LIKELY TO BE PRESENT OR STORED
(GARAGES, STORAGE AND UTILITY AREAS, ETC.): Flammable
liquids (such as gasoline, solvents, propane (LP or butane, etc.) and
other substances (such as adhesives, etc.) emit flammable vapors
which can be ignited by a gas water heater’s hot surface igniter or
main burner. The resulting flashback and fire can cause death or
serious burns to anyone in the area.
This water heater must not be installed directly on carpeting. Carpeting
must be protected by metal or wood panel beneath appliance extending
beyond full width and depth of appliance by at least 3” (7.6 cm) in any direction,
or if appliance is installed in an alcove or closet, entire floor must be covered
by the panel. Failure to heed this warning may result in a fire hazard.
Also, the water heater must be located and/or protected so it is not
subject to physical damage by a moving vehicle.

Propellants of aerosol sprays and volatile compounds (cleaners,
chlorine based chemicals, refrigerants, etc.), in addition to being highly
flammable in many cases, will also react to form corrosive hydrochloric
acid when exposed to the combustion products of the water heater.
The results can be hazardous, and can also cause product failure.
InsulatIon BlanKets
Insulation blankets are available to the general public for external use
on gas water heaters but are not necessary with these products. The
purpose of an insulation blanket is to reduce the standby heat loss
encountered with storage tank heaters. Your water heater meets or
exceeds the Energy Policy Act standards with respect to insulation and
standby loss requirements, making an insulation blanket unnecessary.
Minimum clearances between the water heater and combustible
construction are 0 inch at the sides and rear, 5.5” (14.0 cm) from the
front and 12” (30.5 cm) from the top (standard clearance). If clearances
stated on the heater differ from standard clearances, install water
heater according to clearances stated on the heater.
Should you choose to apply an insulation blanket to this heater, you
should follow these instructions (for identification of components
mentioned below, see Figure 1). Failure to follow these instructions
can restrict the air flow required for proper combustion, potentially
resulting in fire, asphyxiation, serious personal injury, or death.
Adequate clearance 24” (61.0 cm) for servicing this appliance should
be considered before installation, such as changing the anodes, etc.
A minimum clearance of 5.5” (14.0 cm) must be allowed for access to
replaceable parts such as the thermostats, drain valve and relief valve.
When installing the heater, consideration must be given to proper
location. Location selected should be as close to the wall as practicable
and as centralized with the water piping system as possible.
• Do not apply insulation to the top of the water heater, as this will
interfere with safe operation of the blower assembly.
• Do not cover outer door, thermostat or temperature & pressure relief valve.
• Do not allow insulation to come within 2” (5.1 cm) of the floor to
prevent blockage of combustion air flow to the burner.
• Do not cover the instruction manual. Keep it on the side of the
water heater or nearby for future reference.
• Do obtain new warning and instruction labels from the manufacturer
for placement on the blanket directly over the existing labels.
• Do inspect the insulation blanket frequently to make certain it
does not sag, thereby obstructing combustion air flow.
fIGure 3.
fIGure 4.
Agas water heater cannot operate properly without the correct amount
of air for combustion. Do not install in a confined area such as a closet,
unless you provide air as shown in the “Locating The New Water
Heater” section. Never obstruct the flow of ventilation air. If you have
any doubts or questions at all, call your gas supplier. Failure to provide
the proper amount of combustion air can result in a fire or explosion
and cause death, serious bodily injury, or property damage.
coMBustIon aIr and ventIlatIon for
applIances located In unconfIned spaces
unconfIned space is space whose volume is not less than
50 cubic feet per 1,000 Btu per hour (4.8 cubic meters per kW) of the aggregate
input rating of all appliances installed in that space. Rooms communicating
directly with the space in which the appliances are installed, through openings
not furnished with doors, are considered a part of the unconfined space.
In unconfined spaces in buildings, infiltration may be adequate to
provide air for combustion, ventilation and dilution of flue gases.
However, in buildings of tight construction (for example, weather
stripping, heavily insulated, caulked, vapor barrier, etc.), additional air
may need to be provided using the methods described in “Combustion
Air and Ventilation for Appliances Located in Confined Spaces.”
coMBustIon aIr and ventIlatIon for
applIances located In confIned spaces
confIned space is a space whose volume is less than 50 cubic
feet per 1,000 Btu per hour (4.8 cm per kW) of the aggregate input
rating of all appliances installed in that space.
When drawing combustion air from inside a conventionally
constructed building to a confined space, such a space should be
provided with two permanent openings. ONE WITHIN 12 INCHES
(30 cm) OF THE ENCLOSURE TOPAND ONE WITHIN 12 INCHES
(30 cm) OF THE ENCLOSURE BOTTOM. Each opening should have
a free area of one square inch per 1000 Btu/hr (22 cm2/kW) of the
total input of all appliances in the enclosure, but not less than 100
square inches (645 cm2). If the confined space is within a building of
tight construction, air for combustion and ventilation must be obtained
from outdoors. When directly communicating with the outdoors or
communicating through vertical ducts, two permanent openings,

5. Louvers and Grilles: In calculating free area, consideration should
be given to the blocking effect of louvers, grilles or screens protecting
openings. Screens used should not be smaller than 1/4 inch (6.4 mm)
mesh. If the free area through a design of louver or grille is known, it
should be used in calculating the size opening required to provide the
free area specified. If the design and free area is not known, it may be
assumed that wood louvers will be 20-25 percent free area and metal
louversandgrilleswillhave60-75percentfreearea. Louversandgrilles
should be fixed in the open position or interlocked with the equipment
so that they are opened automatically during equipment operation.

Water supply systems may, because of code requirements or such
conditions as high line pressure, among others, have installed devices
suchaspressurereducingvalves,checkvalves,andbackflowpreventers.
Devices such as these cause the water system to be a closed system.

CORROSION MAY RESULT IN FAILURE AND RISK OF ASPHYXIATION.
Spray can propellants, cleaning solvents, refrigerator and air
conditioning refrigerants, swimming pool chemicals, calcium and
sodium chloride (water softener salt), waxes, and process chemicals
are typical compounds which are potentially corrosive.
therMal eXpansIon
As water is heated, it expands (thermal expansion). In a closed system
the volume of water will grow when it is heated. As the volume of water
grows there will be a corresponding increase in water pressure due
to thermal expansion. Thermal expansion can cause premature tank
failure (leakage). This type of failure is not covered under the limited
warranty. Thermal expansion can also cause intermittent Temperature-
Pressure Relief Valve operation: water discharged from the valve due
to excessive pressure build up. This condition is not covered under the
limited warranty. The Temperature-Pressure Relief Valve is not intended
for the constant relief of thermal expansion.
Do not store products of this sort near the heater. Also, air which is
brought in contact with the heater should not contain any of these
chemicals. If necessary, uncontaminated air should be obtained from
remote or outside sources. The limited warranty is voided when failure
of water heater is due to a corrosive atmosphere (see limited warranty
for complete terms and conditions).
water pIpInG
A properly sized thermal expansion tank must be installed on all closed
systems to control the harmful effects of thermal expansion. Contact a
local plumbing service agency to have a thermal expansion tank installed.
note: to protect against untimely corrosion of hot and cold
water fittings, it is strongly recommended that di-electric
unions or couplings be installed on this water heater when
connected to copper pipe.
All gas piping must comply with local codes and ordinances or with the
National Fuel Gas Code (ANSI Z223.1/ NFPA-54). Copper and brass
tubing and fittings (except tin lined copper tubing) should not be used.

instructions for installation of the valves. Before changing the factory
setting on the thermostat, read the “Temperature Regulation” section
in this manual.
This water heater should not be connected to any heating systems or
component(s) used with a non-potable water heating appliance.
All piping components connected to this unit for space heating
applications should be suitable for use with potable water.
Toxic chemicals such as those used for boiler treatment, should not be
introduced into this system.
When the system requires water for space heating at temperatures higher
than required for domestic water purposes, a tempering valve must be
installed. Please refer to Figure 2 for suggested piping arrangement.

Install discharge piping so that any discharge will exit the pipe within
6 inches (15.2 cm) above an adequate floor drain, or external to the
building. In cold climates it is recommended that it be terminated at
an adequate drain inside the building. Be certain that no contact is
made with any live electrical part. The discharge opening must not
be blocked or reduced in size under any circumstances. Excessive

cause restriction and reduce the discharge capacity of the valve.
note: If using copper tubing, solder tubing to an adapter before
attaching the adapter to the water heater connections. do not
solder the water lines directly to the water heater connections.
It will harm the dip tube and damage the tank.
t & p valve and pipe Insulation (if supplied)
Remove insulation for T & P valve and pipe connections from carton.
No valve or other obstruction is to be placed between the Temperature-
Pressure Relief Valve and the tank. Do not connect discharge piping
directly to the drain unless a 6” (15.2 cm) air gap is provided. To prevent
bodily injury, hazard to life, or property damage, the relief valve must be
allowed to discharge water in adequate quantities should circumstances
demand. If the discharge pipe is not connected to a drain or other
suitable means, the water flow may cause property damage.
CAUTION
Temperature-Pressure Relief Valve discharge

The Temperature-Pressure Relief Valve must be manually operated
at least twice a year. Caution should be taken to ensure that (1) no
one is in front of or around the outlet of the Temperature-Pressure
Relief Valve discharge line, and (2) the water manually discharged
will not cause any bodily injury or property damage because the
water may be extremely hot. If after manually operating the valve, it
fails to completely reset and continues to release water, immediately
close the cold water inlet to the water heater, follow the draining
instructions in this manual, and replace the Temperature-Pressure
Relief Valve with a properly rated/sized new one.
If replaced, the new T&P valve must meet the requirements of local
codes, but not less than a combination Temperature-Pressure Relief
Valve rated/sized and certified as indicated in the above paragraph. The
new valve must be marked with a maximum set pressure not to exceed
the marked hydrostatic working pressure of the water heater (150 psi =
1,035 kPa) and a discharge capacity not less than the water heater Btu/
hr or kW input rate as shown on the water heater’s model rating label.
note: In addition to the factory installed Temperature-Pressure
Relief Valve on the water heater, each remote storage tank that may
be installed and piped to a water heating appliance must also have its
own properly sized, rated and approved Temperature-Pressure Relief
Valve installed. Call the toll free technical support phone number
listed on the back cover of this manual for technical assistance in
sizing a Temperature-Pressure Relief Valve for remote storage tanks.
note: The purpose of a Temperature-Pressure Relief Valve is to
prevent excessive temperatures and pressures in the storage tank.
The T&P valve is not intended for the constant relief of thermal
expansion. Aproperly sized thermal expansion tank must be installed
on all closed systems to control thermal expansion, see Closed
Water Systems and Thermal Expansion on page 12.
If you do not understand these instructions or have any questions

When installed at elevations above 7,700 feet (2,347 meters), input
rating should be reduced at the rate of 4 percent for each 1,000
feet (305 meters) above sea level which requires replacement
of the burner orifice in accordance with National Fuel Gas Code
(ANSI Z223.1/NFPA 54). Contact your local gas supplier for
further information.
Gas pIpInG
Failure to replace the standard orifice with a high altitude orifice
when installed could result in improper and inefficient operation of
the appliance, producing carbon monoxide gas in excess of safe
limits, which could result in serious injury or death. Contact your
gas supplier for any specific changes which may be required in
your area.
Make sure the gas supplied is the same type listed on the model rating
plate. The inlet gas pressure must not exceed 14 inch water column (3.5
kPa) for natural and propane gas (L.P.). The minimum inlet gas pressure
shown on the rating plate is that which will permit firing at rated input.
All gas piping must comply with local codes and ordinances or with the
National Fuel Gas Code (ANSI Z223.1/ NFPA-54). Copper or brass
tubing and fittings (except tin lined copper tubing) should not be
used.
Use pipe joint compound or teflon tape marked as being resistant
to the action of petroleum [Propane (L.P.)] gases.
If the gas control valve is subjected to pressures exceeding 1/2 psi
(3.5 kPa), the damage to the gas control valve could result in a fire
or explosion from leaking gas.
The appliance and its gas connection must be leak tested before
placing the appliance in operation.
If the main gas line shut-off serving all gas appliances is used,
also turn “off” the gas at each appliance. Leave all gas appliances
shut “off” until the water heater installation is complete.
The appliance and its individual shut-off valve should be disconnected
from the gas supply piping system during any pressure testing of
that system at test pressures in excess of 1/2 pound per square inch
(3.5 kPa). It should be isolated from the gas supply piping system
by closing its individual manual shut-off valve during any pressure
testing of the gas supply piping system at test pressures equal to
or less than 1/2 pound per square inch (3.5 kPa).
A gas line of sufficient size must be run to the water heater. Consult
the current edition of National Fuel Gas Code (ANSI Z223.1/NFPA
54) and your gas supplier concerning pipe size.
There must be:
Connectingthegaspipingtothegascontrolvalveofthewaterheatercanbe
accomplished by either of the two methods shown in Figures 12 and 13.
• A readily accessible manual shut off valve in the gas supply line
serving the water heater, and
• A sediment trap (drip leg) ahead of the gas control valve to help prevent
dirt and foreign materials from entering the gas control valve.
• A flexible gas connector or a ground joint union between the shut
off valve and control valve to permit servicing of the unit.
Be sure to check all the gas piping for leaks before lighting the water
heater. Use a soapy water solution, not a match or open flame.
Rinse off soapy solution and wipe dry.

Never use this water heater unless it is completely full of water.
To prevent damage to the tank, the tank must be filled with water.
Water must flow from the hot water faucet before turning “ON” gas
to the water heater.
sedIMent traps (drIp leGs)
To fill the water heater with water:
1. Close the water heater drain valve by turning the handle to the
right (clockwise). The drain valve is on the lower front of the
water heater.
2. Open the cold water supply valve to the water heater.
note: the cold water supply valve must be left open when
the water heater is in use.
3. To insure complete filling of the tank, allow air to exit by opening the
nearest hot water faucet. Allow water to run until a constant flow is
obtained. This will let air out of the water heater and the piping.
A sediment trap (drip leg) should be installed as close to the inlet of
the water heater as practical at the time of water heater installation.
The sediment trap should be either a tee fitting with a capped nipple in
the bottom outlet or other device recognized as an effective sediment
trap. If a tee fitting is used, it should be installed in conformance
with one of the methods of installation shown in Figures 12 and 13.
4. Check all water piping and connections for leaks. Repair as
needed.
ventInG
Contaminants in the gas lines may cause improper operation of the
gas control valve that may result in fire or explosion. Before attaching
the gas line be sure that all gas pipe is clean on the inside. To trap
any dirt or foreign material in the gas supply line, a sediment trap
(sometimes called a drip leg) must be incorporated in the piping.
The drip leg must be readily accessible. Install in accordance with
the “Gas Piping” section. Refer to the current edition of the National
Fuel Gas Code (ANSI Z223.1/NFPA 54).

avoid potential freeze-up from condensation.
note: The equivalent feet of pipe listed above are exclusive
of the “45° Elbow” termination. That is, the termination “45°
Elbow”, with installed screen, is assumed to be in the system
and the remainder of the system must not exceed the thirty (30)
equivalent feet of 3 inch pipe or one-hundred (100) equivalent
feet of 4 inch pipe.
Plan the vent system layout so that proper clearances are maintained
from plumbing and wiring.
3. The blower discharge adapter is made to accept only straight
sections of 3” pipe. To start a minimum of 2 inches of 3” pipe
must be attached to the blower discharge. See Figure 16.
Vent pipes serving power vented appliances are classified by
building codes as “vent connectors”. Required clearances from
combustible materials must be provided in accordance with

note: This unit can be vented using only the following
materials: PVC (Cellular Core; ASTM-F891), PVC (DWV;ASTM
D2665 or CSA B181.2), PVC (Sch 40, 80, 120; ASTM D1785 or
CSAB137.3), PVC (SDR Series; ASTM-D2241 or CSAB137.3),
CPVC (CPVC 41; ASTM-D2846 or CSA B137.6), CPVC
(Sch 40, 80; ASTM-F441 or CSA B137.6), CPVC (SDR Series;
ASTM-F442), ABS (Sch 40 DWV;ASTM D2661 or CSAB181.1),
ABS (Sch 40 DWV cellular core;ASTM-F628). The fittings, other
than the TERMINATION should be equivalent to PVC-DWV
fittings meeting ASTM D-2665 (Use CPVC fittings, ASTM F-438
for CPVC pipe and ABS fittings, ASTM D-2661/3311 for ABS
pipe). If CPVC or ABS pipe and fittings are used, then the proper
cement must be used for all joints, including joining the pipe to
the Termination (PVC Material). If local codes do not allow the
use of the PVC termination when a material other than PVC is
used for venting, then an equivalent fitting of that material may
be substituted if the screen in the PVC terminal is removed and
inserted into the new fitting.
PVC Materials should use ASTM D-2564 Grade Cement; CPVC
Materials should use ASTM F-493 Grade Cement and ABS
Materials should use ASTM D-2235 Grade Cement.
Blower asseMBlY InstallatIon
If the water heater is being installed as a replacement for an
existing power vented heater in pre-existing venting, a thorough
inspection of the existing venting system must be performed prior
to any installation work. Verify that the correct material as detailed
above has been used, and that the minimum or maximum vent
lengths and terminal location as detailed in this manual have been
met. Carefully inspect the entire venting system for any signs of
cracks or fractures, particularly at the joints between elbows and
other fittings and the straight runs of vent pipe. Check the system
for signs of sagging or other stresses in the joints as a result of
misalignment of any components in the system. If any of these
conditions are found, they must be corrected in accordance with
the venting instructions in this manual before completing the
installation and putting the water heater into service.
1. Check to make sure that the wire harness is attached to the gas
valve and blower control box.
note: a. For water heaters in locations with high ambient
temperatures (above 100°F) it is recommended that CPVC or
ABS pipe and fittings be used. B. A 22.5 degree elbow (2” vent
pipe) or a 45 degree elbow (3” and 4” vent pipe) with an installed
screen VENT TERMINAL must be used in all cases.
2. Make sure no material is still attached to the outside or inside
of blower assembly.
condensate
Condensate formation does not occur in all installations of power
vented water heaters, but should be protected against on installations
where it can form in the venting system. Condensation in the venting
system of power vented water heaters is dependent upon installation
conditions including, but not limited to ambient temperature and
humidity of installation location, ambient temperature and humidity
of venting space, vent discharge and slope, and product usage. In
certain conditions, installations in unconditioned space or having
long horizontal or vertical vent runs may accumulate condensate.
In these conditions, the vent pipe should be sloped downward
away from the blower assembly (not less than 1/8” (3.2 mm) nor
greater than 1/2” (12.7 mm) per foot maximum). If the vent piping
is vented level or sloped upwards away from the blower assembly,
then adequate means for draining and disposing of the condensate
needs to be made by the installer (if condensate is detected). If you
have condensate, then a 3/8” drain hose can be connected to the
built-in drain port of the rubber boot on the blower assembly. For
your convenience, the rubber boot is supplied with a removable cap
on the built-in drain port. Prior to operating the water heater, make
sure the removable cap is installed on the drain port (if a drain hose
is not needed).

vent pipe is installed up to the wall, with a coupling on the end against
the wall opening, the pipe with the vent terminal can be prepared
for gluing before inserting through the wall. Slide the pipe through
the wall and insert into the coupling on the other side of the wall,
making sure that the vent terminal ends up pointed in the correct
position, see Figure 17.
The water heater must be connected to a grounded metal,
permanent wiring system; or an equipment grounding

It is recommended that Tetrahydrofuran (THF) be used to
prepare the surfaces of pipe and fittings for solvent welding.
Do not use water, rags, gasoline or any other substitutes for
cleaning PVC or CPVC surfaces. A chemical cleaner such as
MEK may be used.
1. InItIal preparatIon
A. Make sure the solvent cement you are planning to use is
designed for the specific application you are attempting.
B. Know the physical and chemical characteristics and limitations of
the PVC and CPVC piping materials that you are about to use.
ceMent
C. Know the reputation of your manufacturer and their products.
Use ASTM D-2564 Grade PVC cement. Never use all-purpose
cements, commercial glues and adhesives or ABS cement to
join PVC or CPVC pipe and fittings.
D. Know your own qualifications or those of your contractor. The
solvent welding technique of joining PVC and CPVC pipe is a
specialized skill just as any other pipe fitting technique.
E. Closely supervise the installation and inspect the finished
job before start-up.
F. Contact the manufacturer, supplier, or competent consulting
agency if you have any questions about the application or
installation of PVC and CPVC pipe.
G. Take the time and effort to do a professional job. Shortcuts
will only cause you problems and delays in start-up. By far,
the majority of failures in PVC and CPVC systems are the
result of shortcuts and/or improper joining techniques.
applIcators
Select a suitable pure bristle type paint brush. Use a proper
width brush or roller to apply the primer and cement (see chart
below). Speedy application of cement is important due to its
fast drying characteristics. IMPORTANT NOTE: A dauber type
applicator should only be used on pipe sizes 2” and below. For
larger diameter pipe, a brush or roller must be used.

accomplished with a miter box saw or wheel type cutter.
Wheel type cutters are not generally recommended for larger
diameters since they tend to flare the corner of the pipe end.
If this type of cutter is used, the flare on the end must be
completely removed.
NOTE: Power saws should be specifically designed to cut plastic pipe.

B. deburring
Use a knife, plastic pipe deburring tool, or file to remove burrs from the
end of small diameter pipe. Be sure to remove all burrs from around the
inside as well as the outside of the pipe. A slight chamfer (bevel) of about
10°-15° should be added to the end to permit easier insertion of the pipe
into the end of the fitting. Failure to chamfer the edge of the pipe may
remove cement from the fitting socket, causing the joint to leak.
step e
f. joint assembly
Working quickly, insert the pipe into the fitting socket bottom and
give the pipe or fitting a 1/4 turn to evenly distribute the cement.
Do not continue to rotate the pipe after it has hit the bottom of the
fitting socket. A good joint will have sufficient cement to make a
bead all the way around the outside of the fitting hub. The fitting
will have a tendency to slide back while the cement is still wet
so hold the joint together for about 15 seconds.
step B
C. Test dry fit of the joint
Tapered fitting sockets are designed so that an interfaced fit should
occur when the pipe is inserted about 1/3 to 2/3 of the way into the
socket. Occasionally, when pipe fitting dimensions are at the tolerance
extremes, it will be possible to fully insert dry pipe to the bottom of
the fitting socket. When this happens, a sufficient quantity of cement
must be applied to the joint to fill the gap between the pipe and fitting.
The gap must be filled to obtain a strong, leak-free joint.
d. Inspection, cleaning, priming
Visually inspect the inside of the pipe and fitting sockets and remove
all dirt, grease or moisture with a clean dry rag. If wiping fails to clean
the surfaces, a chemical cleaner must be used. Check for possible
damage such as splits or cracks and replace if necessary.
depth-of-entry
Marking the depth of entry is a way to check if the pipe has
reached the bottom of the fitting socket in Step F. Measure the
fitting depth and mark this distance on the pipe O.D. You may want
to add several inches to the distance and make a second mark as
the primer and cement will most likely destroy your first one.
step f
G. cleanup and joint movement
Remove all excess cement from around the pipe and fitting with a
dry cotton rag. This must be done while the cement is still soft.
Apply primer to the surface of the pipe and fitting socket with
a natural bristle brush. This process softens and prepares the
PVC or CPVC for the solvent cementing step. Move quickly and
without hesitation to the cementing procedure while the surfaces
are still wet with primer.
The joint should not be disturbed immediately after the cementing
procedure, and sufficient time should be allowed for proper curing
of the joint. Exact drying time is difficult to predict because it
depends on variables such as temperature, humidity and cement
integrity. For more specific information, you should contact your
solvent cement manufacturer.
e. application of solvent cement
• Apply the solvent cement evenly and quickly around the outside of the
pipe at a width a little greater than the depth of the fitting socket.
• Apply a light coat of cement evenly around the inside of the
fitting socket. Avoid puddling.
• Apply a second coat of cement to the pipe end.

teMperature reGulatIon
Any water heater’s intended purpose is to heat water. Hot water is
The water temperature setting was factory set at the lowest temperature;
needed for cleansing, cleaning, and sanitizing (bodies, dishes, clothing).
Untempered hot water can present a scald hazard. Depending on the
time element, and the people involved (adults, children, elderly, infirm,
etc.) scalding may occur at different temperatures.
Pressing the “COOLER”
pressing the “HOTTER”
button decreases temperature and
button increases the temperature.
Setting the water heater temperature at 120°F (49°C) (Approx. “
” mark on temperature setting of gas valve) will reduce the
risks of scalds. Some states require settings at specific lower
temperatures.
It is recommended that lower water temperatures be used to avoid
the risk of scalding. It is further recommended, in all cases, that the
water temperature be set for the lowest temperature which satisfies
your hot water needs. This will also provide the most energy efficient
operation of the water heater.
To avoid any unintentional changes in water temperature settings, the
control has a tamper resistant feature for changing the temperature
setting. To change the temperature setting follow these instructions:
Figure 21shows the approximate water temperatures produced
at various thermostat settings. Short repeated heating cycles
caused by small hot water uses can cause temperatures at the
point of use to exceed the thermostat setting by up to 30°F (17°C).
If you experience this type of use you should consider using lower
temperature settings to reduce scald hazards.
1. “Wake Up” the temperature indicators by holding down both
“COOLER” and “HOTTER” temperature adjustment buttons at
the same time for one second, see Figure 21. One or two of the
temperature indicators will light up. These indicators will only
remain on for 30 seconds if no further buttons are pressed. After
30 seconds the control will go back to “Sleep” mode.
Valves for reducing the point-of-use temperature by mixing cold and
hot water are available, see Figure 2. Also available are inexpensive
devices that attach to faucets to limit hot water temperatures.
Contact a licensed plumber or the local plumbing authority.
2. Release both of the temperature adjustment buttons.
a. To decrease the temperature press and release the “COOLER”
button until the desired setting is reached.
b. To increase the temperature press and release the “HOTTER”
button until the desired setting is reached.
NOTE: Holding down the button will not continue to lower or raise
the temperature setting. The button must be pressed and released
for each temperature change desired.
Should overheating occur or the gas supply fail to shut off, turn off
the manual gas control valve to the appliance.
HOT WATER CAN SCALD: Water heaters are intended to produce
hot water. Water heated to a temperature which will satisfy space
heating, clothes washing, dish washing, and other sanitizing needs
can scald and permanently injure you upon contact. Some people
are more likely to be permanently injured by hot water than others.
These include the elderly, children, the infirm, or physically/mentally
handicapped. If anyone using hot water in your home fits into one of
these groups or if there is a local code or state law requiring a certain
temperature water at the hot water tap, then you must take special
precautions. In addition to using the lowest possible temperature
setting that satisfies your hot water needs, a means such as a mixing
valve should be used at the hot water taps used by these people or
at the water heater. Mixing valves are available at plumbing supply
or hardware stores, see Figure 2. Follow manufacturer’s instructions
for installation of the valves. Before changing the factory setting on
the thermostat, read the “Temperature Regulation” section in this
manual, see Figure 21.

start up condItIons
factors which must all be present for the odor to develop:
sMoKe/odor
a. A concentration of sulfate in the supply water.
b. Little or no dissolved oxygen in the water.
c. A sulfate reducing bacteria which has accumulated within the
water heater (this harmless bacteria is nontoxic to humans).
d. An excess of active hydrogen in the tank. This is caused by the
corrosion protective action of the anode.
It is not uncommon to experience a small amount of smoke and odor
during the initial start-up. This is due to burning off of oil from metal
parts, and will disappear in a short while.
therMal eXpansIon
Smelly water may be eliminated or reduced in some water heater models
by replacing the anode(s) with one of less active material, and then
chlorinating the water heater tank and all water lines. Contact the local
water heater supplier or service agency for further information concerning
an Anode Replacement Kit and this chlorination treatment.
If the smelly water persists after the anode replacement and chlorination
treatment, we can only suggest that chlorination or aeration of the water
supply be considered to eliminate the water problem.
do not remove the anode leaving the tank unprotected. By doing
As water is heated, it expands (thermal expansion). In a closed
system, the volume of water will grow. As the volume of water
grows, there will be a corresponding increase in water pressure
due to thermal expansion. Thermal expansion can cause
premature tank failure (leakage). This type of failure is not
covered under the limited warranty. Thermal expansion can also
cause intermittent temperature-pressure relief valve operation:
water discharged from the valve due to excessive pressure build
up. The temperature-pressure relief valve is not intended for the
constant relief of thermal expansion. This condition is not covered
under the limited warranty.
so, all warranty on the water heater tank is voided.
“aIr” In hot water faucets
A properly-sized thermal expansion tank should be installed
on all closed systems to control the harmful effects of thermal
expansion. Contact a local plumbing service agency to have a
thermal expansion tank installed.
HYDROGEN GAS: Hydrogen gas can be produced in a hot water
system that has not been used for a long period of time (generally
two weeks or more). Hydrogen gas is extremely flammable and
explosive. To prevent the possibility of injury under these conditions,
we recommend the hot water faucet, located farthest away, be
opened for several minutes before any electrical appliances
which are connected to the hot water system are used (such as a
dishwasher or washing machine). If hydrogen gas is present, there
will probably be an unusual sound similar to air escaping through the
pipe as the hot water faucet is opened. There must be no smoking
or open flame near the faucet at the time it is open.
stranGe sounds
Possible noises due to expansion and contraction of some metal
parts during periods of heat-up and cool-down do not necessarily
represent harmful or dangerous conditions.
Condensation causes sizzling and popping within the burner area
during heating and cooling periods and should be considered normal.
See “Condensate” in this section.

This water heater is equipped with an automatic gas shut-off system.
This system works when high water temperatures are present. Turn
“OFF” the entire gas supply to the water heater. The high temperature
shut-off is built into the gas control valve. It is non-resettable. If the
high temperature shut-off activates, the gas control valve must be
replaced. Contact your gas supplier or service agency.

22, make sure that the flow of combustion and ventilation air is not
blocked.
You should also check for sooting. Soot is not normal and will impair
proper combustion. A visual inspection of the main burner and HSI
igniter assembly should also be done at least once a year, see
Figure 22.
Soot build-up indicates a problem that requires correction before
further use. Turn “OFF” gas to water heater and leave off until
repairs are made, because failure to correct the cause of the
sooting can result in a fire causing death, serious injury, or
property damage.
At least once a year a visual inspection should be made of the venting
system. You should look for:
1. Obstructions which could cause improper venting. The
combustion and ventilation air flow must not be obstructed.
2. Damage or deterioration which could cause improper venting or
leakage of combustion products.
fIGure 22.
Be sure the vent piping is properly connected to prevent escape of
dangerous flue gasses which could cause deadly asphyxiation.
Burner cleanInG
Obstructions and deteriorated vent systems may present serious
health risk or asphyxiation.
In the event your burner or burner air openings require cleaning, turn
the blower switch to the “OFF” position and allow the burner to cool.
Call a service agency to remove and clean the burner and correct
the problem that required the burner to be cleaned.
Chemical vapor corrosion of the flue and vent system may occur
if air for combustion contains certain chemical vapors. Spray can
propellants, cleaning solvents, refrigerator and air conditioner
refrigerants, swimming pool chemicals, calcium and sodium chloride,
waxes, bleach and process chemicals are typical compounds which
are potentially corrosive.
houseKeepInG
Vacuum around base of water heater for dust, dirt, and lint on a
regular basis.
If after inspection of the vent system you found sooting or
deterioration, something is wrong. Call the local gas utility to
correct the problem and clean or replace the flue and venting before
resuming operation of the water heater.
Burner operatIon and InspectIon
Flood damage to a water heater may not be readily visible or
immediately detectable. However, over a period of time a flooded
water heater will create dangerous conditions which can cause
DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.
Contact a qualified installer or service agency to replace a
flooded water heater. Do not attempt to repair the unit! It must be
replaced!
At least once a year a visual inspection should be made of the
main burner and the hot surface igniter assembly for proper flame
characteristics and ignition sequences. This can be done by removing
the Outer Door and viewing the main burner operation through the
Viewport on the Inner Door, see Figure 1. The main burner should
provide complete combustion of gas, ignite rapidly, give reasonably
quiet operation, and cause no excessive flame lifting from the burner

INSTALLED IN SUITABLE AREA: To insure sufficient ventilation
and combustion air supply, proper clearances from the water heater
must be maintained. See “Locating the New Water Heater” section.
Combustible materials such as clothing, cleaning materials, or
flammable liquids, etc. must not be placed against or adjacent to
the water heater which can cause a fire.
teMperature-pressure relIef valve operatIon
anode rod InspectIon
The temperature-pressure relief valve must be manually operated
at least once a year.
Each water heater contains at least one anode rod, which will slowly
deplete (due to electrolysis) prolonging the life of the water heater by
protecting the glass-lined tank from corrosion. Adverse water quality,
hotter water temperatures, high hot water usage, and water softening
methods can increase the rate of anode rod depletion. Once the anode
rod is depleted, the tank will start to corrode, eventually developing a leak.
fIGure 23.
Whencheckingthetemperature-pressurereliefvalveoperation, makesure
that(1)nooneisinfrontoforaroundtheoutletofthetemperature-pressure
relief valve discharge line, and (2) that the water discharge will not cause
any property damage, as the water may be extremely hot, see Figure 23.
Certain water conditions will cause a reaction between the anode rod
and the water. The most common complaint associated with the anode
rod is a “rotten egg smell” produced from the presence of hydrogen
sulfide gas dissolved in the water. IMPORTANT: Do not remove this
rod permanently as it will void any warranties. The parts list includes a
special anode rod that can be ordered if water odor or discoloration occurs.
NOTE: This rod may reduce but not eliminate water odor problems. The
water supply system may require special filtration equipment from a water
conditioning company to successfully eliminate all water odor problems.
If after manually operating the valve, it fails to completely reset and
continues to release water, immediately close the cold water inlet
to the water heater, follow the draining instructions, and replace the
temperature-pressure relief valve with a new one.
If the temperature-pressure relief valve on the appliance weeps or
discharges periodically, this may be due to thermal expansion. You
may have a check valve installed in the water line or a water meter with
a check valve. Consult your local water supplier or service agency for
further information. Do not plug the temperature-pressure relief valve.
Artificially softened water is exceedingly corrosive because the
process substitutes sodium ions for magnesium and calcium ions. The
use of a water softener may decrease the life of the water heater tank.
The anode rod should be inspected after a maximum of three years
and annually thereafter until the condition of the anode rod dictates
its replacement. NOTE: artificially softened water requires the anode
rod to be inspected annually.
draInInG
The following are typical (but not all) signs of a depleted anode rod:
* The majority of the rods diameter is less than 3/8”.
* Significant sections of the support wire (approx. 1/3 or more of the
anode rod’s length) are visible.
If the anode rod show signs of either or both it should be replaced.
NOTE: Whether re-installing or replacing the anode rod, check for
any leaks and immediately correct if found.
In replacing the anode:
1. Turn off gas supply to the water heater.
The water heater should be drained if being shut down during
freezing temperatures. Also periodic draining and cleaning of
sediment from the tank may be necessary.
2. Shut off the water supply and open a nearby hot water faucet to
depressurize the water tank.
3. Drain approximately 5 gallons ofwater fromtank (Refer to “Draining
and Flushing” for proper procedures). Close drain valve.
1. Set the blower switch to the “OFF” position.
2. CLOSE the cold water inlet valve to the water heater.
4. Remove old anode rod.
3. OPEN a nearby hot water faucet and leave open to allow for
draining.
5. Use Teflon® tape or approved pipe sealant on threads and install
new anode rod.
4. Connect a hose to the drain valve and terminate to an adequate
drain.
6. Turn on water supply and open nearby hot water faucet to purge air
from water system. Check for any leaks and immediately correct
any if found.
5. OPEN the water heater drain valve to allow for tank draining.
Restart the water heater as directed under “Operating Your Water
Heater.” See the Repair Parts Illustration for anode rod location.
note: If the water heater is going to be shut down and
drained for an extended period, the drain valve should be
left open with hose connected allowing water to terminate
to an adequate drain.
6. CLOSE the drain valve.
