WARNING: Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.

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 gas 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 supply tank valve.

4.Check all joints of gas supply piping system. Apply mixture of liquid soap 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.
