UNVENTED NATURAL GAS FIREPLACE
INSTALLATION

INSTALLING GAS PIPING TO FIREPLACE LOCATION
WARNING: A qualified ser- vice person must connect fire- place to gas supply. Follow all local codes.
Installation Items Needed
Before installing fireplace, make sure you have the items listed below.
•piping (check local codes)
•sealant (resistant to propane/LP gas)
•equipment shutoff valve *
•test gauge connection *
•sediment trap
•tee joint
•pipe wrench
•approved flexible gas line with gas connec- tor (if allowed by local codes) (not provided)
*A CSA
WARNING: Never connect fireplace to private
CAUTION: Use only new, black iron or steel pipe. Inter-
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 24).
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. Never use sealant on flare threads.
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 24. Locate sediment trap where it is within reach for clean- ing. Install in piping system between fuel sup- ply and fireplace. Locate sediment trap where trapped matter is not likely to freeze. A sedi- ment trap traps moisture and contaminants. This keeps them from going into fireplace gas controls. If sediment trap is not installed or is installedwrong,fireplacemaynotrunproperly.

CONNECTING FIREPLACE TO GAS SUPPLY
Installation Items Needed
•5/16" hex socket wrench or
•Phillips screwdriver
•sealant (resistant to propane/LP gas, not provided)
1.If fireplace screen and floor are still installed, see Removing Fireplace Screen and Floor Assembly, page 8.
2.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 25). The flexible gas supply line con- nection to the equipment shutoff valve should be accessible.
3.Attach the flexible gas line to gas sup- ply (see Figure 25). Check tightness of flexible gas line attached to gas regu- lator of fireplace (see Figure 25).
4.Check all gas connections for leaks. See Checking Gas Connections, page 15.
5.Replace fireplace floor assembly. Feed flexible gas line into fireplace base area while replacing fireplace floor assem- bly. Make sure the entire flexible gas line is in fireplace base area.
Note: Be careful of wires and components on underside of fireplace floor. Reattach fireplace floor assembly with screws re- moved in step 3 of Removing Fireplace Screen and Floor Assembly, page 8.
