CHECKING GAS CONNECTIONS
WARNING: Test all gas piping 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 a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see
Figure 18).
2.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas or using compressed air.
3.Check all joints from gas meter to equip- ment shutoff valve for natural gas or pro- pane/LP supply to equipment shutoff valve for propane/LP (see Figures 19 and 20).
Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.
4.Correct all leaks at once.
CAUTION: Make sure external regulator has been installed between propane/LPsupply and fireplace. See guidelines under

PRESSURE TESTING GAS SUPPLY PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1.Disconnect fireplace with its main gas valve (control valve) and equipment shut- off valve from gas supply piping system. Pressures in excess of 1/2 psig will dam- age fireplace 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 or opening main gas valve located on or near gas meter for natural gas or using compressed air.
4.Check all joints of gas supply piping system.
Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Reconnect fireplace and equipment shutoff valve to gas supply. Check recon- nected fittings for leaks.
