Pressure Testing Gas Supply Piping System

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)

1.	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.	Cap off open end of gas pipe where
	equipment shutoff valve was connected.
3.	Pressurize supply piping system by ei-
	ther using compressed air or opening
	propane/LP supply tank valve.
4.	Check all joints of gas supply piping
