CONNECTING FIREPLACE TO GAS SUPPLY

Installation Items Needed

•Phillips screwdriver

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

NOTICE: Most building codes do not permit concealed gas connections. A flexible gas line is provided to allow accessibil- ity from the fireplace (see Fig- ure 1, page 5). The flexible gas supply line connection to the equipment shutoff valve should be accessible.

1.Route flexible gas line, included, from fire- place control to equipment shutoff valve through side or rear access holes in outer cas- ing (see Figure 1, page 5).

2.Apply pipe joint sealant lightly to male threads of gas connector attached to flexible gas line/ equipment shutoff valve (see Figure 23).

CAUTION: Avoid damage to regulator.Holdgasregulatorwith wrench when connecting it to gas piping and/or fittings (Ther- mostat-Controlled Models Only).

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

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

CHECKING GAS CONNECTIONS

WARNING: Test all gas pip- ing and connections, internal and external to unit, for leaks after installing or servicing. Cor- rect all leaks at once.

WARNING: Never use an open flame to check for a leak. Apply a noncorrosive leak de- tection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.

CAUTION: Make sure exter- nal regulator has been installed between propane/LP supply and fireplace. See guidelines under Connecting to Gas Sup- ply, page 17.

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 ex- cess of 1/2 psig will damage heater regulator.

2.Cap off open end of gas pipe where equip-

ment shutoff valve was connected.
