cleaning. Locate sediment trap where trapped matter is
not likely to freeze. A sediment trap prevents moisture
and contaminants from going into the heater controls. If
the sediment trap is not installed or is installed wrong,
the heater may not operate properly.
Test for gas leaks with a mild soap and water solution.
Apply water/soap solution with brush only -
do not over
apply. NEVER test with an open flame.

disconnected from the gas supply piping system during
any pressure testing of the system at test pressures in
excess of 1/2 psi.
The appliance must be isolated from the gas supply
piping system by closing the individual manual shut-off
valve (Fig. 7) during any pressure testing of the gas
supply system at test pressures equal to or less than
1/2 psi.
