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
gascompany concerning pipe size.
There must be:
-A readily accessible manual shut off valve inthe 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 gasconnector 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
"thewater heater. Use a soapy water solution, hot 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 astandard 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.

The appliance and itsgas connection mustbe leak test-
ed before placingthe appliance in operation. 12

Connecting the gas piping to the gas control valve of the
water heater can be accomplished by either of the two
methods shown.
