3.Route gas supply line through access opening of fireplace insert (see Figure 15).

NOTICE: Most building codes do not permit concealed gas connections. A flexible gas line is provided to allow accessibility from the fireplace (see Figure 16). The flexible gas supply line con- nection to the equipment shutoff valve should be accessible.

4.Connect gas supply line to flexible gas line at- tached to gas regulator of fireplace insert (see Figure 16). Use sealant on all male pipe threads.

5.Check all gas connections for leaks. See

CHECKING GAS CONNECTIONS

WARNING:Testallgas piping 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 appliance with its appliance main gas valve (control valve) and equipment shutoff valve from gas supply piping 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 open- ing propane/LP supply tank for propane/LP gas or opening main gas valve located on or near gas meter or using compressed air.

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

5. Correct all leaks at once.

6. Reconnect fireplace insert and equipment shut- off valve to gas supply. Check reconnected fittings for leaks.
