1. Turn "OFF" the gas supply to the water heater.
If the main gas line shutoff valve serving all gas
appliances is used, also shut "OFF" the gas
at each appliance. Leave all gas appliances
shut "OFF" until the water heater installation is
completed. See Figures 5 and 6.
Figure 6
2. Open a nearby hot water faucet until the water
is no longer hot. When the water has cooled,
turn "OFF" the water supply to the water heater
at the water shut off valve or water meter. Some
installations require that the water be turned off
to the entire house. See Figures 5 and 7.
Figure 7
,
Check again to make sure the gas supply is
"OFF" to the water heater. Then disconnect
the gas supply connection from the gas control
valve.
,
Attach a hose to the water heater drain valve
and put the other end in a floor drain or
outdoors. (See Figures 5 and 8.) Open the water
heater drain valve. The water passing out of
the drain valve may be extremely hot. To avoid
being scalded, make sure all connections are
tight and that the water flow is directed away
from any person.
Figure 8
,
Disconnect the vent pipe from the draft hood or
blower where it connects to the water heater. In
most installations the vent pipe can be lifted off
after any screw or other attached devices are
removed. Dispose of the draft hood. The new
water heater has a blower coupling which must
be used for proper operation.
,
If you have copper piping to the water heater,
the two copper water pipes can be cut with a
hacksaw or tubing cutter approximately four
inches away from where they connect to the
water heater. See Figure 9. This will avoid
cutting off pipes too short. Additional cuts can
be made later if necessary. Disconnect the
temperature-pressure relief valve discharge
pipe. When the water heater is drained,
disconnect the hose from the drain valve.
Close the drain valve. The water heater is
now completely disconnected and ready to be
removed.

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 termination 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.
3. Ensure the area has a continuous supply of air
for combustion, dilution and ventilation.
4. Avoid locations that could cause the water
heater to freeze from outside air.
5. Selected location must provide access to a
properly grounded electrical branch circuit. A
dedicated circuit is preferred. Do not use a GFI
outlet.
6. Avoid locations that expose the water heater to
direct sunlight.
7. Keep combustibles such as boxes, magazines,
clothes, etc., away from the water heater area.
8. The water heater must be located and/or
protected so it is not subject to physical
damage by a moving vehicle.
IMPORTANT: Do not use an extension cord to
connect the water heater to an electrical outlet.
IMPORTANT: This heater has special venting
requirements when installed in areas where the
ambient temperatures exceed 110°F (43°C) (see
"Hi( h Ambient Tem )erature Installations"
Property Damage Hazard
• All water heaters eventually leak.
• Do not install without adequate drainage,
Installation of the water heater must be
accomplished in such a manner that if the tank
or any connections should leak, the flow of water
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. In all cases, a metal drain

![](/html/d6/d60e/d60e223ed77afc82ba2a6a14dd5206844f3158f1ffe95fbc530be4ae08162264/bg11.png)
pan should be installed under the water heater.
Such a metal drain pan must have a clearance of
at least 1" (25mm) greater than any point on the
water heater's outer jacket and must be piped to
an adequate drain. The pan must have a maximum
depth of 1.75" (45mm).
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 metal 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 metal 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 metal drain pan that
trigger an alarm or turn off the incoming water to
the water heater when leakage is detected.
• Sensors mounted in the metal drain pan that
turn off the water supply to the entire building
when water is detected in the metal 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.
producing appliance. Examples of such locations
are garages, storage and utility areas.
Fire or Explosion Hazard
• Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.
• Avoid all ignition sources if you smell gas.
• Do not expose water heater control to excessive gas
pressure.
• Use only gas shown on rating plate.
• Maintain required clearances to combustibles.
• Keep ignition sources away from faucets after extended
period of non-use,

water heater.
FIRE AND EXPLOSION HAZARD
Can result in serious injury or death
Storage Of Flammable Liquids
Flammable liquids (such as gasoline, solvents,
propane (LP or butane, etc.) and other substances
(such as adhesives, paints, etc.) emit flammable
vapors which can be ignited by a gas water
heater's hot surface igniter (HSI) or main burner.
The resulting flashback and fire can cause death or
serious burns to anyone in the area.
This water heater is equipped with a FV
(Flammable Vapor) sensor for detecting the
presence of flammable vapors. When the sensor
detects those vapors, the unit will shut down and
not operate. Should this happen, please refer
to the "Troubleshooting Guidelines" section of
this manual. Even though this water heater is a
flammable vapors ignition resistant (FVlR) water
heater and is designed to reduce the chances of
flammable vapors being ignited, gasoline and other
flammable substances should never be stored
or used in the same vicinity or area containing
a gas water heater or other open flame or spark
Fire Hazard
For continued protection against
risk of fire:
• Do not install water heater on
carpeted floor.
• Do not operate water heater if
flood damaged.
Clearances To Combustibles
Minimum clearances between water heater and
combustibles are 0" at the sides and rear, 5.5"
(140mm) from the front and 12" (300mm) from top
(standard clearance.) If clearances stated on the
heater differ from standard clearances, install water
heater according to clearances stated on the heater
(see Figure 11).
NOTE: Do not block air intakes at the rear of the
water heater.

service laundries with dry cleaning equipment, it is
imperative that the water heater or water heaters be
installed so that combustion and ventilation air be
taken from outside these areas.
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.

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 standby
heat loss encountered with storage tank heaters
Your water heater meets or exceeds the current
standards with respect to insulation and standby
loss requirements making an insulation blanket
unnecessary
Should you choose to apply an insulation blanket
to this heater you should follow these instructions
(For identification of components mentioned below
see Figures 14) Failure to follow these instructions
can restrict the air flow required for proper
combustion, dilution and ventilation potentially
resulting in fire asphyxiation serious personal
injury or death
• 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 T&P
relief valve FV sensor or Air Intake Snorkel
• Do not cover the Use & Care Guide 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
Breathing Hazard - Carbon Monoxide Gas
• Do not obstruct water heater air intake(s) with
insulating jacket.
• Gas and carbcn monoxide detectors are available.
• install water heater in accordance with the
instruction manual and NFPA54.

Gas Piping
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.
Fire and Explosion Hazard
• Do not use water heater with
any gas other than the gas
shown on the rating plate.
• Excessive pressure to gas
control valve can cause serious
injury or death.
• Turn off gas lines during
installation.
• Contact qualified installer or
service agency.
Explosion Hazard
Havea qualifiedtechnicianmake surethat the L.P.
gasoperating pressuredoes notexceed13" water
column (3.237kilopascals).
Failureto do so can resultin death, explosion,or
fire.
Make sure the gas supplied is the same type listed
on the model rating plate. The inlet gas pressure
must not exceed 14 inch w.c. (3.5kPa) for natural
gas and propane gas. The minimum inlet gas
pressure shown on the rating plate is that which will
permit firing at rated input.
There must be:
• A readily accessible manual shut-off valve in the
gas supply line serving the water heater, and
• A sediment trap (dirt leg) ahead of gas control
valve/thermostat to help prevent dirt and foreign
materials from entering the gas control valve/
thermostat.
• Aflexible gas connector or a ground joint union
between the shut-off valve and gas control
valve/thermostat to permit servicing of the unit.
Connecting gas piping to the gas control valve/
thermostat of water heater can be accomplished by
either of two methods shown in Figures 13 and 14.

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.
If the gas control valve/thermostat is subjected to
pressures exceeding 1/2 psi (3.5kPa), the damage
to the gas control valve/thermostat 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.

Fire and Explosion Hazard
• Use joint compound or tape
compatible with natural gas
and propane.
• Leak test before operating
heater.
• Disconnect gas piping and
shut-off valve before pressure
testing system.
Use pipe joint compound or Teflon tape marked as
being resistant to the action of gases.
The appliance and its gas connection must be leak
tested before placing the appliance in operation.
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 psi (3.5kPa).
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 psi (3.5kPa).
Sediment Traps/Dirt Leg
Fire and Explosion Hazard
• Contaminants in gas lines can
cause fire or explosion.
• Clean all gas piping before
installation.
• Install sediment trap (dirt leg)
in accordance with NFPA54.
A sediment trap 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 13 and 14.
Contaminants in the gas lines may cause improper
operation of the gas control valve/thermostat 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 dirt leg) must be incorporated in the piping. The
sediment trap 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 5 4).
High Altitude Installation
Breathing Hazard -Carbon Monoxide Gas
• For operation above 10,100 ft.
(3,048 metres) a high altitude
orifice must be installed.
• Contact a qualified installer or
service agency.
Breathing carbon monoxide can cause brain damage or death.
Always read and understand instruction manual.
This heater is approved for operation up to 10,100
feet (3,079 m) without alteration.
Failure to replace standard orifice with a high
altitude orifice when installed above 10,100 feet
(3,079 m) 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.
