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.

4.Check all joints of gas supply piping system. 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 reconnected fittings for leaks.

Test Pressures Equal To or Less Than

1/2 PSIG (3.5 kPa)

1. Close equipment shutoff valve (see Figure 33).

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 34, for propane/LP or Figure 35, for natural gas). Apply noncorrosive leak detec- tion fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.
