INSTALLATION

Continued

CONNECTING FIREPLACE TO GAS SUPPLY

Installation must include an equipment shutoff valve, union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from fireplace (see Figure 16).

IMPORTANT: Install equipment shutoff valve in an accessible location. The equip- ment shutoff valve is for turning on or shutting off the gas to the appliance.

Check your building codes for any special requirements for locating equipment shutoff valve to fireplaces.

Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged fireplace valves.

CAUTION: Use pipe joint seal- ant that is resistant to liquid pe- troleum (LP) gas.

We recommend that you install a sediment trap in supply line as shown in Figure 16. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate sedi- ment trap where trapped matter is not likely to freeze. A sediment trap traps moisture

Installation Items Needed

5/16" hex socket wrench or nut-driver

Phillips screwdriver

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

1.Remove fireplace screen. Remove two screws that hold fireplace screen in place for shipping. These screws are located near top of screen. Discard screws. Lift fireplace screen up and pull out to remove.

2.Remove screws that attach log base assembly to fireplace (see Figure 17). Carefully lift up log base assembly and remove from fireplace (see Figure 17).

CAUTION: Do not pick up log base assembly by burners. This could damage burners. Only handle base by grates.

3.Route gas line (provided by installer) from equipment shutoff valve to fire- place. Route flexible gas supply line through one of the access holes.

NOTICE: Most building codes do not permit concealed gas con- nections. A flexible gas line is provided to allow accessibility from the fireplace (see Figure 18). The flexible gas supply line con- nection to the equipment shutoff valve should be accessible.

4.Attach the flexible gas line to gas sup- ply (see Figure 18). Check tightness of flexible gas line attached to gas regu- lator of fireplace (see Figure 18).

5.Check all gas connections for leaks. See Checking Gas Connections, page 12.

6.Replace log base assembly back into fireplace. Feed flexible gas line into fire- place base area while replacing log base assembly. Make sure the entire flexible gas line is in fireplace base area. Reat- tach log base assembly to fireplace with screws removed in step 2.
