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 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.
