Pressure Testing Gas Supply
Piping System
Test Pressures In Excess Of 1/2 PSIG
1. Disconnect fireplace and its individual
manual shutoff valve from gas supply
piping system. Pressures in excess of 1/2
psig will damage fireplace regulator.
2. Cap off open end of gas pipe where
manual 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

and water to gas joints. Bubbles form-
ing show a leak.
5. Correct all leaks at once.
6. Reconnect fireplace and manual shutoff
valve to gas supply. Check reconnected
fittings for leaks.
WARNING: Test all gas pip-
ing and connections for leaks
after installing or servicing. Cor-
rect all leaks at once.
