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.

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 gassup-
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 gascontrol 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 itsgasconnection must be leak test-
ed before placingthe appliance in operation.
