Sediment Trap - Kenmore 153.556300 Use & Care Manual

Use pipe joint compound or Teflon tape marked as being resistant
to the action of petroleum (Propane [L.P.]) gases.
The appliance and its gas connection must be leak tested before
placing the appliance in operation.
The appliance and its individual shutoff valve shall be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1/2 pound per square inch (3.5 kPa). It shall be isolated from
the gas supply piping system by closing its individual manual
shutoff 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 19 and 20.

Sediment Traps
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 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 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 in
Figures 19 and 20.
