WARNING
Make sure the gas suppliedis the same type listed on the
model ratingplate.Theinlet gaspressure mustnot exceed14
incheswater column [1/5 poundper squareinch (3.5kPa)].
The minimum inlet gaspressure listed on the model rating
plate is for the purpose of input adjustment.
WARNING
/
if the gascontrolvalveissubjected to pressures exceeding Y2 /
pound per squareinch (3.SkPa),the damageto the gas con-
]
trol valvecouldresultin a fire or explosion from leak]ng gas.
WARNING
/
Use pipe joint compound or teflon tape marked as being |
resistantto the action of petroleum[Propane (L.P.)]gases.

SEDIMENT TRAP
A sediment trap shall be installed as close to the 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. If a tee fitting is
used, it shall be installed in conformance with one of the
methods of installation shown below.
WARNING
I If the main gasline shutoffservingall gasappliances is used,I
I
also turn "OFF"thegasat eachappliance. L eaveall gasappli-
I
ancesshutoff untilthe waterheater installation is Complete.
A gas line of sufficient size must be run to the water
heater. Consult the latest edition of National Fuel Gas
Code ANSI Z223.1, also referred to as NFPA54 and the
gas company concerning pipe size.
There must be:
-A readily accessible manual shut off valve in the gas sup-
ply line serving the water heater, and
-A drip leg (sediment trap) 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 shutoffvalve and control valve to permit servicing of
the unit.
Be sure to check al] 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.
Standard Models are for installation up to 3,300 feet
above sea level.
High Altitude Models are for installation from 3,300 to
5,500 feet above sea level.
If a standard model is installed above 3,300 feet or a high
altitude model is installed above 5,500 feet, the input rat-
ing must be reduced at the rate of 4 percent for each
1,000 feet above sea level. Contact your local Sears
Service Center or gas utility for further information.
WARNING
The appliance and its gas connection must be leak test-
ed before placing the appliance in operation.
Connecting the gas piping to the gas control valve of the water
heatercan be accomplishedby either of the two methodsshown.

WARNING
The appliance and its individual s hutoffvalvemust be discon-
nectedfrom the gassupplypipingsystem duringan)' pressure
testingof that system at test pressures in excess of Y_pound
per square inch(3.SkPa).

sures equalto or lessthan% poundper squareinch(3.5kPa).
WARNING
Contaminants in the gaslinesmay causeimproperoperation
of the gascontrolvalvethat may resultin fire or explosion.
Beforeattachingthe gasline be surethat all gaspipe]s clean
on the inside.To trap any dirt or foreignmaterial in the gas
supply line, a drip leg (sometimescaged a sedimenttrap)
mustbe incorporated in the piping. The drip leg must be
readily accessible. Install in accordance with the "Gas
Piping" section.Refer to the latest edition of the National
FuelGas Code,ANSI Z223.1, alsoreferredto as NFPA54.
