4.Route flexible gas line from manual shutoff valve into fireplace through side or rear access panel. Route flexible gas supply line through fireplace access door.

NOTICE

Most building codes do not permit concealed gas connections. A flexible gas line is provided to allow accessibility from the fire- place. The flexible gas supply line connection to the manual shutoff valve should be accessible.

5.Apply pipe joint sealant lightly to male threads of gas connector attached to flexible gas line (see Figure 18). Connect flexible gas line to flexible gas line attached to gas regulator of fireplace (see Figure 18).

6.Check all gas connections for leaks. See Checking Gas Connections, below.

7.Replace log base assembly back into fireplace. Feed flexible gas line into fireplace base area while replacing log base assembly. Make sure the entire flexible gas line is in fireplace base area. Reattach log base assembly to fire- place with screws removed in step 3.

CHECKING GAS CONNECTIONS

WARNING

WARNING ICONG 001

Test all gas piping and connections for leaks after installing or servicing. Correct all leaks at once.

WARNING

WARNING ICON

G 001

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

1.Disconnect fireplace and its individual manual shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig will damage fireplace gas regula- tor.

2.Cap off open end of gas pipe where manual 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 forming show a leak.

5.Correct all leaks at once.

6.Re-connect fireplace and manual shutoff valve to gas supply. Check re-con-

nected fittings for leaks.
