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 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 equipment 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 fire- place, or using compressed air.
4.Check all joints of gas supply piping system. Apply noncorro- sive 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 sup- ply. 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 fire- place, 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 detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.
Pressure Testing Fireplace Gas Connections
1.Open equipment shutoff valve (see Figure 33).
2.Open propane/LP supply tank valve for propane/LP fireplace or main gas valve located on or near gas meter for natural gas fireplace.
3.Make sure control knob of fireplace is in the OFF position.
4.Check all joints from equipment shutoff valve to gas valve (see Figure 34 for propane/LP or Figure 35 for natural gas). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.
5.Light fireplace (see Operating Fireplace, pages 25 and 26). Check all other internal joints for leaks.
6.Turn off fireplace (see To Turn Off Gas to Appliance, page 25).
