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.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1.Disconnect appliance with its appliance main gas valve (con- trol valve) and equipment shutoff valve from gas supply pip- ing system. Pressures in excess of 1/2 psig will damage fire- place regulator.
2.Cap off open end of gas pipe where equipment 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 a non- corrosive leak detection fluid to all joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Reconnect heater 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 22).
2.Pressurize supply piping system by either using compressed air or opening main gas valve located on or near gas meter.
3.Check all joints from gas meter to equipment shutoff valve (see Figure 23). Apply a noncorrosive leak detection fluid to all joints.
4.Correct all leaks at once.
Pressure Testing Fireplace Gas Connections
1.Open equipment shutoff valve (see Figure 22).
2.Open main gas valve located on or near gas meter.
3.Make sure control knob of fireplace is in the OFF position.
4.Check all joints from equipment shutoff valve to thermostat gas valve (see Figure 23). Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Light fireplace (see Operating Fireplace, pages 16 through 18). Check all other internal joints for leaks.
7.Turn off fireplace (see To Turn Off Gas to Appliance, page 17).
8.Replace front panel.
