CONNECTING FIREPLACE TO GAS SUPPLY

Installation Items Needed

5/16" hex socket wrench or nut-driver

sealant (resistant to propane/LP gas, not provided)

1.Open lower louver door panel by gently pulling forward.

2.Route flexible gas line (provided by installer) from equipment shutoff valve to fireplace. Route flexible gas supply line through one of the access holes on side of fireplace.

3.Attach flexible gas line from gas supply to control valve (see Figure 32).

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

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

3.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas fireplace or opening main gas valve located on or near gas meter for natural gas fire- place, or using compressed air.

4.Check all joints of gas supply piping system. Apply noncorro- sive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.

5.Reconnect fireplace and equipment shutoff valve to gas sup- ply. 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 33).

2.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas fireplace or opening main gas valve located on or near gas meter for natural gas fire- place, or using compressed air.

3.Check all joints from propane/LP supply tank or gas meter to equipment shutoff valve (see Figure 34, for propane/LP or Fig- ure 35, page 21, for natural gas). Apply noncorrosive leak de- tection fluid to all joints. Bubbles forming show a leak. Cor- rect all leaks at once.

CHECKING GAS CONNECTIONS

Installation Items Needed WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks at once.

CHECKING GAS CONNECTIONS WARNING: Never use an open flame to check for a leak. Apply noncorrosive leak detection 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 and its individual equipment shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig (3.5 kPa) will damage fireplace gas regulator.
