pound per square inch (3.5 kPa). It should be isolated from the gas

supply piping system by closing its individual manual shut-off valve

during any pressure testing of the gas supply piping system at test

pressures equal to or less than 1/2 pound per square inch (3.5 kPa).

Connecting the gas piping to the gas control valve of the water

heater can be accomplished by either of the two methods shown

in Figures 20 and 21.

SEDIMENT TRAPS

Fire and Explosion Hazard

Contaminates in gas lines can cause

fire or explosion.

Clean all gas piping before

installation.

Install sediment trap in accordance

with NFPA54.

Contaminants in the gas lines may cause improper operation of

the gas control valve that may result in re 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 supply line,

a sediment trap must be incorporated in the piping. The sediment

trap must be readily accessible. Install in accordance with the Gas

Piping section. Refer to the current edition of the National Fuel

Gas Code, ANSI Z223.1/NFPA 54.

A sediment trap should be installed as close to the inlet of the

water heater as practical at the time of water heater installation. The

sediment trap should be either a tee tting with a capped nipple in

the bottom outlet or other device recognized as an effective sediment

trap. If a tee tting is used, it should be installed in conformance with

one of the methods of installation, shown in Figures 20 and 21.
