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 regula-
tor.
2. Cap off open end of gas pipe where manual shutoff valve was connected.
3. Pressurize supply piping system by either 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 forming show a leak.
5. Correct all leaks at once.
6. Re-connect fireplace and manual shutoff valve to gas supply. Check re-con-
nected fittings for leaks.

Figure 19 - Attaching Flexible Gas Lines Together
5. Apply pipe joint sealant lightly to male threads of gas connector attached to
flexible gas line (see Figure 18). Connect flexible gas line to flexible gas line
attached to gas regulator of fireplace (see Figure 19).
6. Check all gas connections for leaks. See Checking Gas Connections, below.
7. Replace log base assembly back into fireplace. Feed flexible gas line into
fireplace base area while replacing log base assembly. Make sure the entire
flexible gas line is in fireplace base area. Reattach log base assembly to fire-
