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 14.
Test Pressures Equal To or Less Than 1/2 PSIG
1.Close manual shutoff valve (see Fig- ure 26).
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 manual shutoff valve (see Figure 27). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.
4.Correct all leaks at once.

CONNECTIONS
1.Open manual shutoff valve (see Figure 26).
2.Open propane/LP supply tank valve.
3.Make sure control knob of fireplace is in the OFF position.
4.Check all joints from manual shutoff valve to thermostat gas valve (see Fig- ure 26). Apply mixture of liquid soap and water to gas joints. Bubbles form- ing 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.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG
1. | Disconnect fireplace and its individual |
| manual shutoff valve from gas supply |
| piping system. Pressures in excess of 1/2 |
| psig will damage fireplace regulator. |
2. | Cap off open end of gas pipe where |
| manual 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 mixture of liquid soap |
| and water to gas joints. Bubbles form- |
| ing show a leak. |
5. | Correct all leaks at once. |
