Attaching Wood Base to Solid Floor

For attaching base to solid floors (concrete or masonry)

Note: Floor anchors and mounting screws are in hardware package. The hardware pack- age is provided with fireplace.

1.Drill holes at marked locations using 5/16" drill bit. For solid floors (concrete or masonry), drill at least 1" deep.

2.Fold floor anchor as shown in Figure 21.

3.Insert floor anchor (wings first) into hole. Tap anchor flush to floor.

4.Insert mounting screws through base and into floor anchors.

5.Tighten screws until base is firmly fas- tened to floor.

CONNECTING TO GAS SUPPLY

WARNING: This appliance re- quires a 45° male flare fitting 5/8"-

The installer must supply an external regu- lator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pressure, fireplace regulator damage could occur. Install external regu- lator with the vent pointing down as shown in Figure 22. Pointing the vent down pro- tects it from freezing rain or sleet.

CAUTION: Use only new, black iron or steel pipe. Inter- nally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" or greater diameter to allow proper gas volume to fireplace. If pipe is too small, undue loss of pressure will occur.

Installation must include a 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 23).

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.

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 23. 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 and contaminants. This keeps them from going into fireplace controls. If sediment trap is not installed or is installed wrong, fireplace may not run properly.

18 UNF (Unified National Fine Thread) inlet connection and the flexible gas line provided.

WARNING: A qualified ser- vice person must connect fire- place to gas supply. Follow all local codes.

CAUTION: Never connect fire- place directly to the propane/LP supply. This fireplace requires an external regulator (not sup- plied). Install the external regula- tor between the fireplace and pro- pane/LP supply.
