CHECKING GAS CONNECTIONS
WARNING: Test all gas pip- ing and connections, internal and external to unit, 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 de- tection 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 fireplace with its appliance main |
gas valve (control valve) and equipment |
shutoff valve from gas supply pipping. Pres- |
sures in excess of 1/2 psig will damage fire- |
place gas regulator. |
Pressure Testing Fireplace Gas Connections
1.Open equipment shutoff valve (see Figure 21).
2.Open main gas valve located on or near gas meter for natural gas or open propane/LP sup- ply tank valve.
3.Make sure control knob of fireplace is in the OFF position.
4.Check all joints from equipment shutoff valve to gas control valve (see Figure 22 or 23). Apply 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 17 and 18). Check all other internal joints for leaks.
7.Turn off fireplace (see To Turn Off Gas to Appliance, page 18).

3. | Pressurize supply piping system by either |
| opening propane/LP supply tank valve for |
| propane/LP gas or opening main gas valve lo- |
| cated on or near gas meter for natural gas, or |
| by using compressed air. |
4. | Check all joints of gas supply piping system. |
| Apply noncorrosive leak detection fluid to all |
| joints. Bubbles forming show a leak. |
5. | Correct all leaks at once. |

tings for leaks. |
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Figure 21).
2.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve lo- cated on or near gas meter for natural gas, or using compressed air.
3.Check all joints from gas meter for natural or propane/LP supply to equipment shutoff valve (see Figure 22 or 23). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.
4.Correct all leaks at once.
