INSTALLATION

Continued

2.Remove screws that attach log base assem- bly to fireplace insert (see Figure 18). Care- fully lift up log base assembly and remove from fireplace insert (see Figure 18).

Note: If adding the G8010 series brick liner accessory, install it now. Follow instruc- tions in G8010 accessory kit.

CAUTION: Do not pick up log base assembly by burners. This could damage burners. Only handle base by grates.

3.Route gas supply line through access opening of fireplace insert (see Figure 2, page 3).

NOTICE: Most building codes do not permit concealed gas con- nections. A flexible gas line is provided to allow accessibility from the fireplace (see Figure 19). The flexible gas supply line con- nection to the equipment shutoff valve should be accessible.

4.Connect gas supply line to flexible gas line attached to gas regulator of fire- place insert (see Figure 19). Use seal- ant on all male pipe threads.

5.Check all gas connections for leaks. See Checking Gas Connections.

6.Replace log base assembly back into fire- place insert. Feed flexible gas line into fire- place insert base area while replacing log base assembly. Make sure the entire flex- ible gas line is in fireplace insert base area. Reattach log base assembly to fireplace insert with screws removed in step 2.

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.

Pressure Testing Gas Supply Piping System

Test Pressures In Excess Of 1/2 PSIG (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 fireplace insert gas regulator.

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

3.Pressurize supply piping system by either using compressed air or opening main gas valve located on or near gas meter.

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.

6.Reconnect fireplace insert and equip- ment shutoff valve to gas supply. Check reconnected fittings for leaks.

Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)

1.Close equipment shutoff valve (see Figure 20).

2.Pressurize supply piping system by either using compressed air or opening main gas valve located on or near gas meter.

3.Check all joints from gas meter to equip- ment shutoff valve (see Figure 21). Ap- ply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.

Pressure Testing Fireplace Insert Gas Connections

1.Open equipment shutoff valve (see Figure 20).

2.Open main gas valve located on or near gas meter.

3.Make sure control knob of fireplace insert is in the OFF position.

4.Check all joints from equipment shutoff valve to thermostat gas valve (see Fig- ure 21). 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 insert (see Operating Fireplace Insert, pages 14 through 16). Check all other internal joints for leaks.

7.Turn off fireplace insert (see To Turn Off Gas to Appliance, page 15).
