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 NFPA 54 and the gas company con-
cerning pipe size.
There must be:
• A readilyaccessible 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 enteting the gas enntroi
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 all the gas piping for leaks before lighting the
water heater. Use a soapy water solution, not a march or open
throe. Rinse offsoapy solution and wipe dry.
Standard Models are for installation up to 3,300 feet above sea
level.
fI-_h Altitude Models are for installation from 3,300 to 5,500
t 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 taring must he
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
