This gas water heater was manufactured to voluntary safety standards to reduce the likelihood of a flammable vapor ignition incident.
The new technology used in meeting these standards makes this product more sensitive to installation errors. Please review the
following checklist and make any required installation upgrades or changes.

Questions? Contact Sears at 1-800-4-MY-HOME (1-800-469-4663).

Installation Checklist

Water Heater Location

Water heater location is important and
performance. Please check the following:

[]

Installation area free of corrosive elements and flammable
materials.

[] Centrally located with the water piping system (For new

installations). Located as close to the gas piping and vent
pipe system as possible.

[] Located indoors and in a vertical position. Protected from

freezing temperatures.

[] Proper clearances from combustible surfaces

maintained and not installed directly on a carpeted floor.

[] Provisions made to protect the area from water damage.

Metal drain pan installed and piped to an adequate drain.

[] Sufficient room to service the water heater. See Clearances

and Accessibility section of this manual.

[] Water heater not located near an air moving device.
[] Is the installed environment dirty (excessive amounts of

lint, dirt, dust, etc.)? If so, the base-ring filter located on
the bottom of the water heater will need to be cleaned

periodically. Refer to the "Maintenance of your Water
Heater" section of this manual for information on cleaning

the base-ring filter.

Combustion Air Supply and Ventilation

Check for sufficient combustion air supply. Insufficient air for
the combustion of gas wilt result in the flame becoming "lazy",

thereby allowing heat to build up in the combustion chamber.
This excessive heat wilt cause a thermal switch on the door

assembly to trip. Isthe water heater installed in a closet or other
small, enclosed space? If so:

[]

Are there openings for make-up air to enter and exit the
room/area?

[]

Are the openings of sufficient size? Remember, if there
are other gas-fired or air-consuming appliances in the

same room, you need more make-up air. Refer to the
"Installation Instructions" and "Combustion Air Supply and
Ventilation" sections for specific requirements.

[]

Make sure that fresh air is not taken from areas that contain
negative pressure producing devices such as exhaust fans,

dryers, fireplaces, etc.

[]

Is there a furnace/air handler in the same room space as
the water heater? If so, has a return air duct system been
attached that exits the room? If so, check for leaks on the

air duct system. If no air duct system is present, correct
immediately by contacting a local Heating, Ventilation, Air-
Conditioning & Refrigeration (HVAC-R) authorized service

provider.

[]

Use a fresh air supply that is free of corrosive elements and
flammable vapors.

can affect system

[]

Fresh air openings must be sized correctly with consideration
given to the blocking effect of louvers and grilles.

[]

Ductwork must be the same cross-sectional area as the
openings.

Vent Pipe System

Check for proper drafting at the water heater draft hood. Refer
to the "Checking the Draft" section of this manual for the test

procedure. If the procedure shows insufficient draft is present,
please check the following:

[]

Draft hood properly installed.

[]

Vent connectors securely fastened with screws and
supported properly to maintain six inch clearance.

[]

Vent connector made of approved material and sized
correctly.

[]

Vent pipe system installed according to all local and state
codes or, in the absence of local and state codes, the

"National Fuel Gas Code", ANSI Z223.1(NFPA 54)-current
edition.

[] Flue baffle properly positioned in the flue tube.
[] Check the vent system for restrictions/obstructions and

check the vent termination height. Refer to the "Combustion
Air Supply and Ventilation" section of this water heater
manual for specific requirements.

[] Recheck for sufficient combustion air supply.

Water System Piping

[] Temperature and pressure relief valve properly installed with

a discharge line run to an open drain and protected from
freezing.

[] All piping properly installed and free of leaks.
[] Heater completely filled with water.

[] Closed system pressure build-up devices installed.
[] Mixing valve (when applicable) installed per manufacturer's

instructions (See "Water Temperature Regulation" section).

Gas Supply and Piping

[] Gas type is the same as that listed on the water heater rating

plate.

[] Gas line equipped with shut-off valve, union, and drip leg.
[] Use pipe joint compound or teflon tape marked as being

resistant to the action of petroleum [Propane (L.R)] gases.

[]

Adequate pipe size and approved pipe material.

[]

An approved noncorrosive leak detection solution used
to check all connections and fittings for possible gas leaks.
Correct any leak found.

Attach a hose to the water heater
drain valve and put the other end

in a floor drain or outdoors. (See
Figures 2 and 5.) Open the water
heater drain valve. Open a nearby

hot water faucet which will relieve

pressure in the water heater and
speed draining. 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.

Disconnect the vent pipe from the draft hood 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 draft hood 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 approximately four

inches away from where they connect to the water heater.

See Figure 6. This will avoid cutting off pipes too short.
Additional cuts can be made later if necessary. Disconnect the
temperature-pressure relief valve drain line. 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.

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 2 and 3.

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 2

and 4.

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.

If you have galvanized pipes to the water heater, loosen
the two galvanized pipes with a pipe wrench at the union in
each line. Also disconnect the piping remaining to the water

heater. See Figure 7. These pieces should be saved since
they may be needed when reconnecting the new water heater.

Disconnect the temperature-pressure relief valve drain line.
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.

Mineral buildup or sediment may have accumulated in the
old water heater. This causes the water heater to be much

heavier than normal and this residue, if spilled out, could

cause staining.
