INSTALLATION

Continued

4.Attach the flexible gas line to gas supply (see Figure 20). Check tightness of flexible gas line attached to gas regulator of fire- place (see Figure 20).

5.Check all gas connections for leaks. See Checking Gas Con- nections.

6.Replace log base assembly back into fireplace. Feed flexible gas line into fireplace base area while replacing log base as- sembly. Make sure the entire flexible gas line is in fireplace base area. Reattach log base assembly to fireplace with screws removed in step 2, page 12.

3.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas, or using com- pressed 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.

6.Reconnect fireplace and equipment shutoff valve to gas sup- ply. Check reconnected fittings for leaks.

CHECKING GAS CONNECTIONS

WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct 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 between propane/LP supply and fireplace. See guidelines under Connecting Fireplace to Gas Supply, page 12.

Pressure Testing gas Supply Piping system

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)

1.Disconnect fireplace with its main gas valve (control valve) and equipment shutoff valve from gas supply piping system. Pres- sures in excess of 1/2 psig will damage fireplace regulator.

2.Cap off open end of gas pipe where equipment shutoff valve was connected.

4. Correct all leaks at once.

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 supply 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 Figures 22 or 23, page 14). 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 15 through 17. Check all other internal joints for leaks.

7.Turn off fireplace (see To Turn Off Gas to Appliance, page 16).
