CHECKING GAS CONNECTIONS
WARNING:Testallgaspiping and connections, internal and external to unit, for leaks after installing or servicing. Correct all leaks at once.
WARNING: Never use an open flame to check for a leak. Apply noncorrosive leak detection fluid 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 (3.5 kPa)
1.Disconnect fireplace and its individual equipment shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig (3.5 kPa) will damage fireplace gas regulator.
2.Cap off open end of gas pipe where equip- ment shutoff valve was connected.
3.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas fireplace or opening main gas valve located on or near gas meter for natural gas fireplace or using compressed air.
4.Check all joints of gas supply piping sys- tem. Apply noncorrosive leak detection
fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.
5.Reconnect fireplace and equipment shutoff valve to gas supply. Check recon- nected fittings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Fig- ure 34).
2.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas fireplace or opening main gas valve located on or near gas meter for natural gas fireplace or using compressed air.
3.Check all joints from propane/LP supply tank or gas meter to equipment shutoff valve (see Figure 35 or Figure 36). Ap- ply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.
