Gas Piping
AWARNING
Make sure the gas supplied is the same type listed on the
model rating plato, The inlet gas pressuremust not exceed
10.5 in.water column (2.6kPa) for natural gas or 13 in, water
column (3.2kPa) for propane (L.R) gas. The minimum inlet
gas pressure listed on the model rating plate is for the pur-
poseof input adjustment.

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 nip-
ple in the bottom outlet or other device recognized as an effec-
tive sediment trap. Ifa tee fitting is used, it shall be installed in
conformance with one of the methods of installation shown
below.
Connecting the gas piping to the gas control valve of the water
heater can be accomplished by either of the two methods shown.
GAS PIPING WITH
FLEXIBLE CONNECTOR
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 referredto as NFPA54 and the gascompany concern-
ing pipe size.
Ther_ i_l._t be;
• A readily accessible manual shut off valve in the gas supply 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
shutoff valve and control valve to permit servicing of the unit.
Be sure to check all the gas piping for leaks before lighting the
water heater. Use a soapy water solution, not a match or open
flame.Rinseoffsoapysolution and wipe
Standard Modds are for instanadoa up to 3,300 feet above sea
level.
High Altitude Modds are for installation from 3,300 to 5,500
leer above sea level.
Ifa standard model is installed above 3,300 feet or a high altitude
model is installed above 5,500 feet, the input rating 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

AWARNING
The appliance and Its gas connection must be leak tested
beforeplac ng the appliance n operation.
AWARNING
• The applianceand its individualshutoffvalve must be discon-
nected from the gassupplypiping s/stem during any pressure
testing of the gas system at test pressuresin excessof I/2
• poundper square inch(3.5kPa).
The appliancemust be isolatedfrom the gassupply pipingsys-
tem by €_ng its iedhddu_ manual shuto_ valve during any
pressuretestingof the gassupply piping systemat test pres-
suresequalor lessthan I/2 poundper square inch(3.SkPa).

AWARNING
Contaminants in the gaslinesmay causeimpmpor operation
of the gas control valve that may result in fire or explosion.
Before at_'mching 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 accordancewith the "Gas Piping _'
section. Refer to the latest edition of the National Fuel Gas
Code, ANSI Z223.1, also referred to as NFPA 54.
