and connections, internal and external to unit, 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 detec- tion 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 log set with its individual equip- ment shutoff valve from gas supply piping system.

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

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

4. Check all joints of gas supply piping system. Apply noncorrosive leak detection fluid to gas joints. Bubbles forming show a leak.

5. Correct all leaks at once.

6. Reconnect log set and equipment 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 5).

2. Pressurize supply piping system by either us- ing 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 6). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

4. Correct all leaks at once.

Hearth Kit assembly and installation

1.Determine which side the gas line will be coming into the fireplace.

NOTICE: Unit comes preassembled with gas inlet on right side. If your fireplace gas supply is on the left, gas inlet should be repositioned to left side of unit.

2.If gas supply line in your fireplace is on the right side, continue to step 3. If not, see Reposition- ing the Gas Inlet to the Left Side of Unit.

3.Install adapter fitting that comes with log set into fireplace gas supply pipe (see Figure 7). Seal using thread sealant.
