INSTALLATION

Connecting Fireplace Insert To Gas Supply (Cont.) Checking Gas Connections

INSTALLATION

Continued

NOTICE: Most building codes do not permit con- cealed gas connections. A flexible gas line is pro- vided to allow connection with the fireplace (see Figure 20). The flexible gas supply line connection to the equipment shutoff valve should be accessible.

4.Connect gas supply line to flexible gas line attached to gas regulator of fireplace insert (see Figure 20). Use sealant on all male pipe threads.

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

6.Replace log base assembly back into fireplace insert. Feed flexible gas line into fireplace insert base area while replacing log base as- sembly. Make sure the entire flexible 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 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.

Pressure Testing Gas Supply Piping System

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

1.Disconnect appliance from its appliance main gas valve (con- trol valve) and equipment shutoff valve from gas supply pip- ing system. Pressures in excess of 1/2 psig will damage fire- place insert gas regulator.

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 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 a non- corrosive leak detection fluid to all joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Reconnect fireplace insert 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 21).
