Gas Piping

WARNING

Make sure the gassuppl!ed is the same type listed on the model rating plate./ne Jme[ gas pressure must not exceed 14

inches water column [I/2 pound per square inch (3.5kPa)]. The minimum inlet gas pressure listed on the model rating

plate is for the purpose of input adjustment.

WARNING

If the gas control valve is subjected to pressuresexceeding '/2

i pound-per square inch (3.5kPa), the damage to the gas con- rol valve could result in a fire or explosion from leakng gas.

WARNING

If the main gas line shutoff serving all gas appliances is used, also turn "OFF" the gas at each appliance. Leave all gasappli-

ancesshut oH until the water heater installation is complete.

L

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 val_,e and control valve to permit servicing of the unit.

Be sureto check all 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.

Ifa 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 SeWice Center or gas ut I ty for further information.

appliance and its individual shutoff valve must be discon- ned_ from the gas supply piping systemduring any pressure llesting of that system at test pressures in excess of'I/2 pound

_square inch (3.5kPa).. .

ll_ appliance must be isolated from the gas supply piping sys-

Jte_nby closing its individual manual shutoff valve during any

Ipressure testing of the gas supply piping system at test pres- qual to or lessthan 1/2pound per square inch (3.5kPa).

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.

Connecting the gas piping to the gas control valve of the water heatercan beaccomplishedby either of the two methodsshown.

WARNING

Contaminants in the gas lines may cause improper operation of the gas control valve that may result in fire or explosion. Before attaching the gas line be sure that all gas pipe is clean on the inside. "to trap any dirt or foreign material in the gas supplyline, a drip leg (sometimes caged a sediment trap) mustbe incorporated-in the piping. The drip leg must De readily accessible. Install in accordance with the "Gas Piping_ section. Refer to the latest edition of the National

Fuel Gas Code, ANSI Z223.1, also referred to as NFPA 54.
