Manual backgroundWARNING: 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 main gas valve located on or near gas meter.

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.

Test Pressures Equal To or Less Than 1/2 PSIG

1.Close manual shutoff valve (see Fig- ure 33).

2.Pressurize supply piping system by ei- ther using compressed air or opening main gas valve located on or near gas meter.

3.Check all joints from gas meter to manual shutoff valve (see Figure 34). Apply mixture of liquid soap and wa- ter to gas joints. Bubbles forming show a leak.
