2.Route flexible gas line, included, from fireplace control to equipment shutoff valve through side or rear access holes in outer casing.

3.Apply pipe joint sealant lightly to male threads of gas connec- tor attached to flexible gas line/equipment shutoff valve (see Figure 32).

CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting it to gas piping and/or fittings (Thermostat-Controlled Mod- els Only).

CAUTION: Avoid damage to gas control. Hold gas control with wrench when connecting it to gas piping and/or fittings (Remote-Ready Models Only).

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

5.Replace branch support back into fireplace. Feed flexible gas line into fireplace base area while replacing branch support. Make sure the entire flexible gas line is in fireplace base area. Reat- tach branch support to fireplace with screws removed in step 1.

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.

CAUTION: Make sure external regulator has been installed between propane/LP supply and fireplace. See guidelines under Connecting to Gas Supply, pages 17 and 18.

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 sys-

tem. Pressures in excess of 1/2 psig will damage heater regulator.

6.

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 sup- ply tank valve for propane/LP gas or opening main gas valve lo- cated on or near gas meter for natural gas, or using compressed air.
