Disconnect appliance with its appliance
main gas valve (control valve) and equip-
ment shutoff valve from gas supply pip-
ing system. Pressures in excess of 1/2 psig
will damage heater regulator.

2.

Pressurize supply piping system by ei-
ther using compressed air or opening
propane/LP supply tank valve.
