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 noncorrosive leak detection fluid 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 14.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Fig- ure 27).
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 28). Apply a noncorrosive leak detection fluid 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 Fig- ure 27).
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 28). Apply a noncorrosive leak de- tection fluid to gas joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Light fireplace (see Operating Fire- place, pages 17 and 18). Check all other internal joints for leaks.
7.Turn off fireplace (see To Turn Off Gas to Appliance, page 18).
8.Replace front panel.
(3.5 kPa)
1. | Disconnect appliance with its appliance |
| main gas valve (control valve) and equip- |
| ment shutoff valve from gas supply pip- |
| ing system. Pressures in excess of 1/2 |
| psig will damage heater regulator. |
2. | Cap off open end of gas pipe where |
| equipment shutoff valve was connected. |
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 a noncorrosive leak de- |
| tection fluid to gas joints. Bubbles |
| forming show a leak. |
