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 13.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Figure 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 equipment 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.

Pressure Testing Fireplace Gas Connections
1.Open equipment 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 equipment shutoff valve to thermostat gas valve (see Fig- ure 27). 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 18 through 20). Check all other internal joints for leaks.
7.Turn off fireplace (see To Turn Off Gas to Appliance, page 19).
8.Replace front panel.
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 sup- |
| ply piping system. Pressures in excess of |
| 1/2 psig will damage fireplace 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 mixture of liquid soap |
