CHECKING GAS
CONNECTIONS
WARNING: Test all gas pip- ing and connections for leaks after installing or servicing. Cor- rect all leaks at once.
WARNING: Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.
CAUTION: Make sure external regulator has been installed be- tween propane/LP supply and fire- place. See guidelines under Con- necting to Gas Supply, page 12.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Figure 23).
2.Pressurize supply piping system by ei- ther using compressed air or opening propane/LP supply tank valve.
3.Check all joints from propane/LP sup- ply tank to equipment shutoff valve (see Figure 24). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.
4.Correct all leaks at once.

Pressure Testing Fireplace Gas Connections
1.Open equipment shutoff valve (see Figure 23).
2.Open propane/LP supply tank valve.
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 Fig- ure 22, page 13). Apply mixture of liq- uid soap and water to gas joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Light fireplace (see Operating Fire- place, 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.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1.Disconnect appliance with its appli- ance main gas valve (control valve) and equipment shutoff valve from gas supply piping system. Pressures in ex- cess of 1/2 psig will damage fireplace regulator.
2.Cap off open end of gas pipe where equipment shutoff valve was con- nected.
3.Pressurize supply piping system by ei- ther using compressed air or opening propane/LP supply tank valve.
4.Check all joints of gas supply piping system. Apply mixture of liquid soap and water to gas joints. Bubbles form- ing show a leak.
5.Correct all leaks at once.
6.Reconnect heater and equipment shutoff valve to gas supply. Check re- connected fittings for leaks.
