WATER PIPING - MIXING VALVE USAGE
*The side recirculation loop connections may not be used as the primary water inlet and outlet connections. For your convenience, plugs are installed
in these fittings at the factory. Remove these plugs if needed for your specific installation. Otherwise (as with all connections) check for leaks while
filling the tank with water and after completing the installation.
FIGURE 2.
This appliance has been design certified as complying with
American National Standard/CSA 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, and the physically or developmentally
disabled. If anyone using hot water from this heater 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, shall be used at the hot water taps used
by these people or at the water heater, see Figure 2. 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.
Water (Potable) Heating and Space Heating: All models are
considered suitable for water (potable) heating and space heating. 9
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 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 building 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 the
appliance extending beyond the full width and depth of the appliance
by at least 3” (7.6 cm) in any direction, or if the appliance is installed
Also, the water heater must be located and/or protected so it is not
subject to physical damage by a moving vehicle.

in an alcove or closet, the entire floor must be covered by the panel.
Failure to heed this warning may result in a fire hazard.
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.
COMBUSTION AIR AND VENTILATION
A gas 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 “Facts to Consider About
Location” 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.
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.
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.
FIGURE 4.
INSULATION BLANKETS
FIGURE 5.
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.
If this water heater will be used in beauty shops, barber shops, cleaning
establishments, or self-service laundries with dry cleaning equipment,
it is imperative that the water heater (s) be installed direct vent so that
all air for combustion and ventilation is taken from outdoors.
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 also cause product failure.
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.
Appliances 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 “Appliances
in Confined Space” that follows.”
Appliances in Confined Spaces
• 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 the 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
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 shall be provided with
two permanent openings. ONE WITHIN 12 INCHES (30 cm) OF
THE ENCLOSURE TOP AND ONE WITHIN 12 INCHES (30
cm) OF THE ENCLOSURE BOTTOM. Each opening shall have
11
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).
Btu per hour (11 cm2/kW)) of total input rating of all equipment in the
enclosure, see Figure 9.
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, located in the above manner,
shall be provided. Each opening shall have a free area of not less
than one square inch per 4000 Btu/hr (5.5 cm2/kW) of total input of all
appliances in the enclosure. If horizontal ducts are used, each opening
shall have a free area of not less than one square inch per 2000 Btu/
hr (11cm2/kW) of the total input of all appliances in the enclosure.
A. ALL AIR FROM INSIDE BUILDINGS: (See Figure 5 and 6)
The confined space shall be provided with two permanent openings
communicating directly with an additional room(s) of sufficient volume
so that the combined volume of all spaces meets the criteria for an
unconfined space. The total input of all gas utilization equipment installed
in the combined space shall be considered in making this determination. Each opening shall have a minimum free area of one square inch
per 1,000 Btu per hour (22 cm2/kW) of the total input rating of all gas
utilization equipment in the confined space, but not less than 100 square
inches (645 cm2). One opening shall commence within 12 inches
(30 cm) of the top and one commencing within 12 inches (30 cm) of the
bottom of the enclosures.
FIGURE 8.
4. When ducts are used, they shall be of the same cross-sectional area
as the free area of the openings to which they connect. The minimum
short side dimension of rectangular air ducts shall not be less than 3
inches (7.6 cm), see Figure 9.
FIGURE 9.
FIGURE 6.
5. Alternatively a single permanent opening may be used when
communicating directly with the outdoors, or with spaces that freely
communicate with the outdoors. The opening shall have a minimum
free area of 1 square inch per 3,000 BTU per hour (8.3 cm2/kW) of
total input rating of all equipment in enclosure. See Figure 9A.
B. ALL AIR FROM OUTDOORS: (See Figures 7, 8 and 9)
The confined space shall be provided with two permanent openings,
one commencing within 12 inches (30 cm) of the top and one
commencing within 12 inches (30 cm) from the bottom of the enclosure.
The openings shall communicate directly, or by ducts, with the outdoors
or spaces (crawl or attic) that freely communicate with the outdoors.
1. When directly communicating with the outdoors, each opening shall have
a minimum free area of 1 square inch per 4,000 Btu per hour (5.5 cm2/kW)
of total input rating of all equipment in the enclosure, see Figure 7.
FIGURE 9.
6. Louvers and Grilles: In calculating free area, consideration shall be given
to the blocking effect of louvers, grilles or screens protecting openings. Screens
used shall 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 louvers and grilles will have 60-75 percent free area. Louvers
and grilles shall be fixed in the open position or interlocked with the equipment
so that they are opened automatically during equipment operation.
FIGURE 7.
2. When communicating with the outdoors through vertical ducts, each
opening shall have a minimum free area of 1 square inch per 4,000
Btu per hour (5.5 cm2/kW) of total input rating of all equipment in the
enclosure, see Figure 8.
7. Special Conditions Created by Mechanical Exhausting or Fireplaces:
operation of exhaust fans, ventilation systems, clothes dryers or
fireplaces may create conditions requiring special attention to avoid
unsatisfactory operation of installed gas utilization equipment.
3. When communicating with the outdoors through horizontal ducts, each
opening shall have a minimum free area of 1 square inch per 2,000

INSTALLING THE NEW WATER HEATER
CHEMICAL VAPOR CORROSION
CLOSED WATER SYSTEMS
CORROSION OF THE FLUEWAYS AND VENT SYSTEM MAY OCCUR IF
AIR FOR COMBUSTION CONTAINS CERTAIN CHEMICAL VAPORS. SUCH
CORROSION MAY RESULT IN FAILURE AND RISK OF ASPHYXIATION.
Water supply systems may, because of code requirements or such
conditions as high line pressure, among others, have installed devices
such as pressure reducing valves, check valves, and back flow preventers.
Devices such as these cause the water system to be a closed system.
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.
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
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 temperaturepressure 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.
A properly sized thermal expansion tank should be installed
on all closed systems to control the harmful effects of thermal
expansion..
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, cleaning 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
physically or developmentally disabled. If anyone using hot water 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,
shall be used at the hot water taps used by these people or at the water
heater, see Figure 2. Valves for reducing point of use temperature by
mixing cold and hot water are also available:
Consult a Qualified Installer or Service Agency. 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.
This water heater shall 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 shall be suitable for use with potable water.
Toxic chemicals, such as those used for boiler treatment shall 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.
FIGURE 10.
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, see Figure 2 also.
13
Figures 2 and 10 show the typical attachment of the water piping to
the water heater. The water heater is equipped with 3/4 inch NPT
water connections.
If replaced, the valve must meet the requirements of local codes, but
not less than a combination temperature and pressure relief valve
certified as indicated in the above paragraph.
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.
The 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 input rate as shown on the water heater’s
model rating plate.
T & P Valve and Pipe Insulation (if supplied)
For safe operation of the water heater, the relief valve must not be
removed from its designated opening nor plugged.
Remove insulation for T & P valve and pipe connections from
carton.
The temperature-pressure relief valve must be installed directly into
the fitting of the water heater designed for the relief valve. Position
the valve downward and provide tubing so that any discharge will
exit only within 6 inches (15.2 cm) above, or at any distance below
the structural floor. 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 length,
over 30 feet (9.14 m), or use of more than four elbows can cause
restriction and reduce the discharge capacity of the valve, see
Figures 10.
No valve or other obstruction is to be placed between the relief
valve and the tank. Do not connect tubing directly to discharge
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 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.
FIGURE 11.
Fit pipe insulation over the incoming cold water line and the
hot water line. Make sure that the insulation is against the top
cover of the heater.Fit T & P valve insulation over valve. Make
sure that the insulation does not interfere with the lever of the
T & P valve.
Secure all insulation using tape.
Temperature-Pressure Relief Valve
The Discharge Pipe:
•Shall not be smaller in size than the outlet pipe size of the valve, or
have any reducing couplings or other restrictions.
•Shall not be plugged or blocked.
•Shall be of material listed for hot water distribution.
•Shall be installed so as to allow complete drainage of both the
temperature-pressure relief valve, and the discharge pipe.
•Shall terminate at an adequate drain.
•Shall not have any valve between the relief valve and tank.
This heater is provided with a properly certified combination
temperature - pressure relief valve by the manufacturer.
The valve is certified by a nationally recognized testing laboratory
that maintains periodic inspection of production of listed equipment of
materials as meeting the requirements for Relief Valves for Hot Water
Supply Systems, ANSI Z21.22 • CSA 4.4, and the code requirements
of ASME.
14
HIGH ALTITUDE INSTALLATIONS
The temperature-pressure relief valve must be manually
operated at least once a year , see Figure 28. 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, and
replace the temperature-pressure relief valve with a new one.
Gas Piping
Rated inputs are suitable up to 10,100 feet (3,079m) elevation. Consult
the factory for installation at altitudes over 10,100 feet (3,079m).
WARNING: THIS HIGH EFFICIENCY WATER HEATER IS CERTIFIED
FOR USE WITHOUT MODIFICATION FOR AN ALTITUDE OF 10,100
FEET (3,079 METERS). INSTALLATIONS ABOVE THESE ALTITUDES
MAY REQUIRE REPLACEMENT OF BURNER ORIFICE. CALL THE
TECHNICAL CENTER AT (800) 527-1953 FOR REQUIREMENTS.
Make sure gas supplied is same type listed on 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 rating plate is that which will permit firing at rated input.
Some gas utility companies derate their gas for altitude, making
it unnecessary to install high altitude orifices. Call the local gas or
utility company to verify BTU content.
Due to the input ration reduction at high altitudes, the output rating
of the appliance is also reduced and should be compensated for in
the sizing of the equipment for applications.
All gas piping must comply with local codes and ordinances or with the
National Fuel Gas Code (ANSI Z223.1/ NFPA-54) or the Natural
Gas and Propane Installation Code (CAN/CSA B149.1) whichever
applies. Copper or brass tubing and fittings (except tin lined copper
tubing) shall not be used.
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.
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.
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) or the Natural Gas and Propane Installation
Code (CAN/CSA B149.1) and your gas supplier concerning pipe
size.
Use pipe joint compound or teflon tape marked as being resistant
to the action of petroleum [Propane (L.P.)] gases.
There must be:
The appliance and its gas connection must be leak tested before
placing the appliance in operation.
• A readily accessible manual shut off valve in the gas supply
line serving the water heater, and
• A flexible gas connector or a ground joint union between the
shut off valve and control valve to permit servicing of the
unit.
The appliance and its individual Shut-off valve shall 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 shall 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).
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.
Important: Make sure the gas line is piped in with
hard pipe. Avoid flex line construction for gas due
to possible gas flow problems.
• A drip leg (sediment trap) ahead of the gas control valve to help
prevent dirt and foreign materials from entering the gas control
valve.
15
VENTING
SEDIMENT TRAPS
A sediment trap shall be installed as close to the gas inlet of the water
heater as practical at the time of water heater installation. The sediment
trap shall be either a tee fitting with a capped nipple in the bottom outlet
or other device recognized as an effective sediment trap.
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 drip leg (sometimes
called a sediment trap) 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) or the Natural Gas and Propane
Installation Code (CAN/CSA B149.1).
VENT PIPE TERMINATION
Filling the Water Heater
The first step is to determine where the vent pipe will terminate.
See Figures 19, 20, and 21. The vent may terminate through a
sidewall as shown in Figure 19 or through the roof as shown in
Figures 20 and 21.
The vent system must terminate so that proper clearances
are maintained as cited in local codes or the current
edition of the National Fuel Gas Code, (ANSI Z223.1, 12.9.1
through 12.9.4) or the Natural Gas and Propane Installation
Code (CAN/CSA-B149.1).
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.
Instructions on proper installation through a sidewall are provided
in Figures 15A, 15B, 15C, and 15D.
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.
4. Check all water piping and connections for leaks. Repair as needed.
Plan the vent system layout so that proper clearances are
maintained from plumbing and wiring.
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
information in this manual under Facts to Consider About
Location and INSTALLING THE WATER HEATER, and with
the National Fuel Gas Code and local codes.

PLANNING THE VENT SYSTEM
of existing venting system must be performed prior to any installation
work. Verify that 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 joints between elbows and other fittings and straight runs of vent
pipe. Check system for signs of sagging or other stresses in 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 installation
and putting the water heater into service.
Plan the route of the vent system from the exhaust elbow to the
planned location of the vent terminal.
1. Layout total vent system to use a minimum of vent pipe and elbows.
2. This water heater is capable of venting flue gases equivalent to
25’ (7.6 m) of 2” pipe, 65’ (19.8 m) of 3” pipe, or 128’ (39.0 m) of
4” pipe as listed in Table 1.

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.
The minimum vent lengths for each of the pipe sizes is one 90° plus
2’ (61 cm) of straight pipe and the appropriate termination.
4. There will be some installations where condensate will be formed
in the horizontal runs of the vent system. This condensate will
run into the condensate elbow. The water heater is shipped with
a condensate hose that attaches to the condensate elbow. No
other tee or fitting is required.
CONDENSATE
NOTE: The equivalent feet (m) of pipe listed above are exclusive
of the termination. That is, the termination, with an installed
screen, is assumed to be in the system and the remainder of the
system must not exceed the lengths discussed above.
3. The exhaust elbow assembly is designed to accept only straight
sections of 2” pipe. To start, a minimum of 2” (5.1cm) of 2” pipe
must be inserted and glued to the exhaust elbow assembly if
utilizing 3” or 4” vent pipe. Use the same method with the blower
inlet if a direct vent configuration is utilized.
If using 2” inch vent pipe:
A minimum of 2” (5.1cm) diameter vent pipe must be attached
to the exhaust elbow assembly. The total system cannot exceed
the lengths discussed above, where each elbow is equal to 5
equivalent feet (1.5m) of straight pipe.
If using 3” or 4” inch vent pipe:
Two inches (5.1cm) of 2” pipe must be attached to the exhaust
elbow assembly before adding a reducer to acquire the desired
pipe diameter. An appropriately sized 45 degree elbow (supplied
locally-a schedule 40 DWV) vent terminal must be obtained with
an equivalent screen (supplied in vent kit). The total system cannot
exceed the equivalent pipe lengths discussed above where each
elbow is equal to 5 feet (1.5m) of straight pipe (3” vent pipe) or 8
feet (2.4m) of straight pipe (4” vent pipe).
U.S. INSTALLATIONS:
NOTE: This unit can be vented with PVC pipe materials (Cellular Core
ASTM-F891; DWV ASTM-D2665 or CSA B181.2; Schedule 40, 80,
120 ASTM-D1785 or CSA B137.3; or SDR Series ASTM-D2241 or
CSA B137.3), CPVC pipe materials (CPVC41 ASTM-D2846 or CSA
B137.6; Schedule 40, 80 ASTM-F441 or CSA B137.6; or SDR Series
ASTM-F442), ABS pipe materials (Schedule 40 DWV ASTM-D2661
or CSA B181.1 or Schedule 40 DWV Cellular Core ASTM-F628). The
fittings, other than the TERMINATION should be equivalent to PVCDWV 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 proper cement must
be used for all joints, including joining the pipe to 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.
Canadian Installation of this water heater must comply with CAN/
CSA B149.1 - Natural Gas and Propane Installation Code which
requires the vent system components be certified to ULC S636.
This water heater has been design certified to be vented with PVC
pipe certified and marked as complying with ULC S636. This water
heater is supplied with a 2 inch 22.5 degree termination elbow that is a
special fitting that must be used with the appliance. Any outlet piping,
fittings and glue used to vent this appliance that is not supplied by the
manufacturer must comply with the ULC S636 requirements.
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.
If the water heater is being installed as a replacement for an existing
power vented heater in pre-existing venting, a thorough inspection
This water heater is a condensing unit and requires a drain to be located in
close proximity to allow the condensate to drain safely. The condensate
drains from the unit at the exhaust tee located at the bottom of the unit
(see figure 16). Condensate from this water heater is mildly acidic.
Please note that some local codes require that condensate is treated
by using a pH neutralizing filter prior to disposal.
Caution must be used to ensure that the drain is free and clear of debris
and will not allow backflow through the condensate hose. Consideration
must be given to avoid freezing of the condensate lines which could
result in excessive build up of condensate inside the water heater.
Waterproof heat tape may be required to prevent freezing of the condensate
lines. Please ensure that the outlet of the condensate drain does
not create a slippery condition which could lead to personal injury.
CONDENSATION WARNING: THIS WATER HEATER IS A CONDENSING
UNIT AND REQUIRES A DRAIN TO BE LOCATED IN CLOSE PROXIMITY
TO ALLOW CONDENSATE TO DRAIN SAFELY. THE CONDENSATE
DRAINS FROM UNIT AT THE EXHAUST ELBOW LOCATED AT
BOTTOM OF UNIT. NOTE: IT IS IMPORTANT THAT THE CONDENSATE
HOSE NOT BE ELEVATED ABOVE THE EXHAUST ELBOW, SEE
FIGURE 16. CONDENSATE BUILD-UP WILL BLOCK THE EXHAUST
OUTLET, WHICH WILL CAUSE IMPROPER OPERATION.

INSTALLATION OF VENT SYSTEM
DIRECT VENTING
Before beginning installation of piping system thoroughly read
the section of this manual VENT PIPE PREPARATION.
The air intake provided on the unit contains a mesh screen to prevent
large particles from entering the unit.
If you are installing your system so that it vents through roof,
please refer to section titled INSTALLATION OF VERTICAL
VENT SYSTEM.
VENT TERMINAL INSTALLATION, SIDEWALL
1. Install the vent terminal by using the cover plate as a template
to mark the hole for the vent pipe to pass through the wall. BEWARE OF CONCEALED WIRING AND PIPING INSIDE
THE WALL.
2. If the Vent Terminal is being installed on the outside of a
finished wall, it may be easier to mark both the inside and
outside wall. Align the holes by drilling a hole through the
center of the template from the inside through to the outside.
The template can now be positioned on the outside wall using
the drilled hole as a centering point for the template.
FIGURE 18B.
WHEN THE UNIT IS TO BE SETUP AS A DIRECT VENT, THE
MESH SCREEN MUST BE REMOVED. THE INLET VENT PIPE
MAY THEN BE GLUED TO THE AIR INTAKE (See Figure 18B)
PROVIDED ON THE UNIT. THE SCREEN REMOVED FROM THE
INTAKE NEEDS TO BE INSERTED INTO THE 2” - 22.5 DEGREE
VENT TERMINAL SUPPLIED IN THE VENT TERMINAL KIT.
3. A) MASONRY SIDE WALLS
Chisel an opening approximately one half inch (1.3 cm) larger
than the marked circle.
B) WOODEN SIDE WALLS
Drill a pilot hole approximately one quarter inch (0.64 cm) outside
of the marked circle. This pilot hole is used as a starting point
for a saws-all or sabre saw blade. Cut around the marked
circle staying approximately one quarter inch (0.64 cm) outside
of the line. (This will allow the vent to easily slide through
the opening. The resulting gap will be covered up by the
Vent Terminal cover plate.) Repeat this step on inside wall if
necessary.
DIRECT VENT TERMINAL INSTALLATION IMPORTANT
THIS UNIT CONSISTS OF TWO VENT TERMINALS - AN INTAKE
VENT TERMINAL AND AN EXHAUST VENT TERMINAL. THE INTAKE
VENT TERMINAL IS A 2” 22.5° PVC ELBOW(-) WITH A MESH WIRE
SCREEN AND THE EXHAUST VENT TERMINAL IS A 2” 22.5° PVC
ELBOW WITH A MESH WIRE SCREEN.
NOTE: TO PREVENT EXHAUSTING PRODUCTS FROM
CIRCULATING TO THE AIR INTAKE IN WINDY/COLD AREAS,
THE MAXIMUM PRACTICAL DISTANCE BETWEEN THESE TWO
TERMINALS IS RECOMMENDED.
SEQUENCE OF INSTALLATIONS, FIGURE 18A
Cut a length of PVC pipe about 3.5 inches (8.9 cm) longer than the
wall thickness at the opening. Glue the vent terminal to this
section of pipe. Slide the wall plate over the pipe to stop against
the vent terminal. Place a bead of caulking (not supplied) around
the gap between the pipe and cover plate. Apply enough to
fill some of the gap between the pipe and wall. Place some of
the caulking on the back of the plate to hold it against the wall
after installation. If the 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 18A.
FIGURE 18C.
WHEN LOCATING THE TERMINALS ON A SIDEWALL, THE
FOLLOWING SPECIFICATIONS PERTAINING TO TERMINAL
LOCATION MUST BE FOLLOWED.
1. The intake air terminal and the exhaust vent terminal must terminate
on the same exterior wall and must be separated by a minimum of
24” (61cm) on vertical centerline (see Figure 18C). In colder climates
increasing the 24” (61cm) minimum will reduce possibility of frost
over from side winds blowing exhaust vapors to the air intake of the
direct vent.
2. The horizontal centerline of the intake air terminal may not be located
lower than the horizontal centerline of the exhaust vent terminal (see
Figure 18C).

1. After the points of termination have been determined,
use the cover plates as templates to mark the holes for
the vent pipes to be inserted through the wall. BEWARE OF
CONCEALED WIRING AND PIPING INSIDE OF WALL. If the
vent terminals are being installed on the outside of a finished
wall, it may be easier to mark both the inside and outside
wall. Align the holesby drilling a hole through the center of the
template from the inside through to the outside. The template
can now be positioned on the outside wall using the drilled holes
as a centering point for the template.
A.) MASONRY SIDE WALLS Chisel an opening approximately
1/2” (1.3 cm) larger than the marked circle.
B.) WOODEN SIDE WALLS Drill a pilot hole approximately
one quarter inch outside of the marked circle. This
pilot hole is used as a starting point for a saws-all or
sabre saw blade. Cut around the marked circle staying
approximately one quarter inch outside of the line.
(This will allow the vent pipe to easily slide through
the opening. The resulting gap will be covered by the
vent terminal cover plates.) Repeat this step on the
inside wall if necessary.
2. Cut a length of 3” PVC pipe about 3.5” (8.9 cm) longer than the
wall thickness at the opening.
3. Glue the intake vent terminal to the section of the pipe.
4. Slide the wall plate over pipe to stop against intake vent terminal.
5. Place a bead of caulking (not supplied) around the gap between

SAFETY CONSIDERATIONS
3. Partially assemble concentric vent termination kit. a) Cement Y concentric fitting to larger diameter kit
pipe, see Figure A.
b) Cement rain cap to smaller diameter kit pipe, see Figure A.
Installing and servicing water heating equipment can be hazardous due to
gas and electrical components. Installation and service of the concentric
vent termination requires ability equivalent to that of a qualified installer or
service agent, see page 2. All precautions in the literature, on tags, and
labels attached to the unit must be observed.
Follow all safety codes. Wear safety glasses and work gloves. Figure d.
NOTE: Instead of cementing the smaller pipe to the rain cap, a
field-supplied stainless steel screw may be used to secure the
2 components together when field disassembly is desired for
cleaning, see Figure D.

WARNING
When using alternate screw method, drill clearance hole in rain
cap and pilot hole in vent pipe for screw size being used. Failure
to drill adequate holes may cause cracking of PVC components,
allowing combustion products to be recirculated. Failure to
follow this warning could result in personal injury or death.
WARNING
Do not operate the heater with rain cap removed or recirculation
of combustion products may occur. Water may also collect inside
larger combustion-air pipe and flow to the burner enclosure.
Failure to follow this warning could result in product damage or
improper operation, personal injury or death.

field-supplied stainless steel screw may be used to secure the
2 components together when field disassembly is desired for
cleaning, see Figure D.
NOTE: All vent terminations must be the same height when
installing multiple unit venting. If assembly is too short to meet
height requirement, the 2 pipes supplied in the kit may be replaced
by using same diameter, field supplied SDR-26 PVC (D2241) pipe.
Do not extend the 21-1/8” dimension outer pipe to be more than
60 inches, see Figure B.
WARNING
When using alternate screw assembly method, drill clearance
hole in rain cap and pilot hole in vent pipe for screw being
used. Failure to drill adequate holes may cause cracking
of PVC components, allowing combustion products to be
recirculated. Failure to follow this warning could result in
personal injury or death.
CAUTION
Do not use field-supplied couplings to extend pipes. Airflow
restriction will occur and the heater pressure switch may cause
intermittent operation.
WARNING

VENT PIPE PREPARATION
PRIMER
1. INITIAL PREPARATION.
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.
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.
C.)Know the reputation of your manufacturer and their products.
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.
CEMENT
The cement should be a bodied cement of approximately 500 to
1600 centipoise viscosity containing 10-20% (by weight) virgin PVC
material solvated with tetrahydrofuran (THF). Small quantities of
dimethyl formamide (DMF) may be included to act as a retarding
agent to extend curing time. Select the proper cement; Schedule 40
cement should be used for Schedule 40 pipe. Never use all-purpose
cements, commercial glues and adhesives or ABS cement to join PVC
or CPVC pipe and fittings.
2. SELECTION OF MATERIALS.
•
Cutting Device - Saw or Pipe Cutter.
•
Deburring Tool, Knife, File, or Beveling Machine (2” and above).
•
Brush - Pure Bristle.
•
Rag - Cotton (Not Synthetic).
•
Primer and Cleaner.
•
Solvent Cement - PVC for PVC Components and CPVC for CPVC
Components.
•
•
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.
RECOMMENDED BRUSH* SIZE FOR PRIMER
AND CEMENT APPLICATIONS
Containers - Metal or Glass to hold Primer and Cement. Select the
type of PVC or CPVC materials to be used on the basis of their
application with respect to chemical resistance, pressure rating,
temperature characteristics, etc.
Nominal Pipe (IPS)
Size Brush Width

1.5” (3.8cm)
3
1.5”-2.5” (3.8cm - 6.4cm)
*USE ONLY NATURAL BRISTLE
Insertion Tool - Helpful for larger diameter pipe and fittings 6 inches
(15.2cm) and above.
3. MAKING THE JOINT.
A.)Cutting Pipe must be squarely cut to allow for the proper
interfacing of the pipe end and the fitting socket bottom. This
can be 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.
STEP A
26
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 B
C. Test dry fit of the joint
STEP E
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.
F. Joint assembly
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.
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 F
G. Cleanup and joint movement
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.
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.
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.

CONTROLS AND SWITCHES
open. When this switch prevents the unit from igniting, most likely the
exhaust is blocked by some means. Check to see if the condensate
is allowed to flow freely from the exhaust elbow and for obstructions
in the exhaust venting and exhaust vent terminal. Also verify that
the vent length does not exceed the maximum allowed as shown in
the Vent Section of this manual.
This model is provided with three pressure switches. These switches
are essential to the safe and proper operation of the unit. All switches
are wired in series. The controller is set up to shut the unit down
whenever there is a failure of any of the switches. It is important to
understand the purpose of each switch.
BLOCKED INTAKE SWITCH
(SEE FIGURE 12)
The Blocked Intake Switch is set up to shut the unit off when a
build-up of negative pressure in the intake air pipe occurs. This
switch is a negative pressure switch that requires an increase in
negative pressure to change the electrical contacts from normally
closed to open. The switch is connected to the pressure tap on the
PVC pipe connected to the inlet of the blower. When this switch
prevents the unit from igniting, most likely the intake is blocked.
Verify that the screen on the intake air connection (conventional
vent), the intake air pipe and termination (direct vent installations)
are free of obstructions that may prevent air from entering the unit.
Insure the screen on intake air connection has been removed on
direct vent installations, see Figure 18B. Also verify the intake
air pipe length does not exceed the maximum allowed as shown
in the Vent Section of this manual.
FIGURE 12.
ON/OFF SWITCH
BLOWER PROVER SWITCH
(SEE FIGURE 12)
The ON/OFF Switch is a single-pole, single-throw rocker switch. This
switch provides 120V from the line source to the heater.
The Blower Prover Switch is provided on the heater to verify that
the fan is operating. It is a positive pressure switch whose electrical
contacts are normally open. When the fan increases the pressure
in the burner, the pressure switch will allow the electrical contacts
to close. The pressure switch is connected to the burner tap by a
piece of tygon tubing. This tubing must be connected in order for
the switch to change the electrical contacts. The controller requires
that the electrical contacts on this air flow switch be open before it
will allow the blower to come on.

to the igniter, sufficient heat is generated to ignite the main burner.
Although improvements have been made to strengthen the igniter,
it is still fragile and care must be taken when handling the igniter to
prevent breakage.

TEMPERATURE REGULATION
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 temperatures 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.
The water temperature is controlled using the Temperature
Control on the Display at the front of the unit (See Figure 1).
This control utilizes a temperature probe to determine the tank
temperature. The primary temperature probe is located at the
top of the tank.
The temperature may be adjusted from 90°F/32°C to 180°F/82°C.
The thermostat was adjusted to 120°F/49°C before the heater
was shipped from the factory. It is recommended that lower water
temperature 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 and minimize scale formation.
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.
The table below shows the approximate time-to-burn relationship for
normal adult skin. 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 20°F/11°C. If you experience this
type of use, you should consider using lower temperature settings
to reduce scald hazards.
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 from this heater 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, shall 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.

The water heater should be located in an area where the general
public does not have access. If a suitable area is not available,
a cover should be installed over the thermostat to prevent
tampering. The water temperature setting was factory set at

HI LIMIT SWITCH (E.C.O.)
The top immersion well of the dual bulb controller also contains
the high limit (energy cutoff) sensor. The high limit switch
interrupts main burner gas flow should water temperature reach
approximately 202°F/94°C.
Should the high limit switch activate, the control system will
automatically reset the unit once the water temperature in the
tank falls below 140°F/60°C. If the unit is manually shut down
and restarted, as long as the temperature in the tank is lower
than 160°F/71°C, the unit will reset and initiate operation.
If you experience higher than usual water temperature along with
frequent automatic resetting of the system, this is evidence of high
limit switch operation. The following are possible reasons for high
limit switch operation.
THE WATER HEATER SHOULD BE LOCATED IN AN AREA
WHERE THE GENERAL PUBLIC DOES NOT HAVE ACCESS TO
SET TEMPERATURES.
•
SETTING THE WATER HEATER TEMPERATURE AT 120°F/49°C
WILL REDUCE THE RISK OF SCALDS. Some states require
settings at specific lower temperatures.
A malfunction in the thermostatic controls would allow the gas
valve to remain open causing water temperature to exceed the
thermostat setting. The water temperature would continue to
rise until high limit switch operation.
Contact your dealer or servicer if continued high limit switch
operation occurs.

FOR YOUR INFORMATION
START UP CONDITIONS
OPERATIONAL CONDITIONS
SMOKE/ODOR
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.
SMELLY WATER
In each water heater there is installed at least one anode rod (see
parts section) for corrosion protection of the tank. Certain water
conditions will cause a reaction between this rod and the water.
The most common complaint associated with the anode rod is one
of a “rotten egg smell” in the hot water. The smell is a result of four
factors which must all be present for the odor to develop:
THERMAL EXPANSION
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.
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 a qualified service agency for
further information concerning an Anode Replacement Kit and this
chlorination treatment.
Water supply systems may, because of such events as high
line pressure, frequent cut-offs, the effects of water hammer
among others, have installed devices such as pressure
reducing valves, check valves, back flow preventers, etc.
to control these types of problems. When these devices
are not equipped with an internal by pass, and no other
measures are taken, the devices cause the water system
to be closed. As water is heated, it expands (thermal expansion)
and closed systems do not allow for the expansion of
heated water.
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
so, all warranty on the water heater tank is voided.
“AIR” IN HOT WATER FAUCETS
The water within the water tank expands as it is heated
and increases the pressure of the water system. If the
relieving point of the water heater’s temperature-pressure
relief valve is reached, the valve will release excess pressure. The
temperature-pressure relief valve is not intended for the constant
relief of thermal expansion. This is an unacceptable condition and
must be corrected. It is recommended that any devices
installed which could create a closed system have a
by-pass and/or the system have an expansion tank
or device to relieve the pressure built by thermal
exp an sion in the water system. Expansion tanks are
available for ordering through a local plumbing
c o n t r a c t o r. C o n t a c t t h e l o c a l w a t e r h e a t e r s u p p l i e r
or qualified service agency for assistance in controlling these
situations.
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.

PERIODIC MAINTENANCE
Venting System Inspection
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. 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.
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.
Burner Cleaning
In the event your burner or burner air openings require cleaning,
turn the on/off switch to the “OFF” position and allow the unit to cool.
Call a qualified service agency to remove and clean the burner and
correct the problem that required the burner to be cleaned.
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.
Housekeeping
Vacuum around base of water heater for dust, dirt, and lint on a
regular basis.
Be sure the vent piping is properly connected to prevent escape of
dangerous flue gasses which could cause deadly asphyxiation.
Obstructions and deteriorated vent systems may present serious
health risk or asphyxiation.
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.
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
37
INSTALLED IN SUITABLE AREA: To insure sufficient ventilation and
combustion air supply, proper clearances from the water heater must
be maintained. See “Facts to Consider About Location” 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.
When checking the temperature-pressure relief valve operation,
make sure that (1) no one is in front of or around the outlet of the
temperature-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 28.
ANODE ROD INSPECTION
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 a
qualified service agency for further information. Do not plug the
temperature-pressure relief valve.
The anode rod is used to protect the tank from corrosion. Most hot
water tanks are equipped with an anode rod. The submerged rod
sacrifices itself to protect the tank. Instead of corroding the tank,
water ions attack and eat away the anode rod. This does not affect
the water’s taste or color. The rod must be maintained to keep the
tank in operating condition.
Draining
Anode deterioration depends on water conductivity, not necessarily
water condition. A corroded or pitted anode rod indicates high water
conductivity and should be checked and/or replaced more often than an anode rod that appears to be intact. Replacement of a depleted
anode rod can extend the life of your water heater. Inspection should
be conducted by a qualified technician, and at a minimum should be
checked annually after the warranty period.
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.
Temperature-Pressure
Relief Valve Operation
1. Set the power switch to the “OFF” position.
2. CLOSE the cold water inlet valve to the water heater.
3. OPEN a nearby hot water faucet and leave open to allow for
draining.
4. Connect a hose to the drain valve and terminate to an adequate
drain.
5. OPEN the water heater drain valve to allow for tank draining.
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.
7. Follow instructions in the “Filling The Water Heater” section.
8. Follow the lighting instructions on the label or see “Lighting
Instructions” in this manual to restart the water heater.

Service
the water heater contact a qualified service agency.
If you are not thoroughly familiar with gas codes, your water heater,
and safety practices, contact your gas supplier or qualified installer
to check the water heater.
Use this guide to check a “Leaking” water heater. Many suspected
“Leakers” are not leaking tanks. Often the source of the water can
be found and corrected.
Read this manual first. Then before checking the water heater make
sure the gas supply has been turned “OFF”, and never turn the gas
“ON” before the tank is completely full of water.
If a condition persists or you are uncertain about the operation of
LEAKAGE CHECKPOINTS
Never use this water heater unless it is completely filled with 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.
A *Condensation may be seen on pipes in humid weather or pipe
connections may be leaking.
B. *The anode rod fitting may be leaking.
C. Small amounts of water from temperature-pressure relief valve
may be due to thermal expansion or high water pressure in your
area.
D. *The temperature-pressure relief valve may be leaking at the
tank fitting.
E . Water from a drain valve may be due to the valve being slightly
opened.
F. *The drain valve may be leaking at the tank fitting.
G. Combustion products contain water vapor which can condense
on the cooler surfaces of the tank. Droplets form and drip onto
the burner or run on the floor. This is common at the time of
start-up after installation and when incoming water is cold.
H. Water in the water heater bottom or on the floor may be from
condensation, loose connections, or the relief valve. DO NOT
replace the water heater until a full inspection of all possible water
sources is made and necessary corrective steps taken.
Leakage from other appliances, water lines, or ground seepage
should also be checked.
* To check where threaded portion enters tank, insert cotton
swab between jacket opening and fitting. If cotton is wet, follow
“Draining” instructions in the “Periodic Maintenance” section and
then remove fitting. Put pipe dope or teflon tape on the threads
and replace. Then follow “Filling the Water Heater” instructions
in the “Installing the New Water Heater” section.
