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 package 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 22.

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.

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 al- low proper gas volume to fire- place. If pipe is too small, un- due loss of pressure will occur.

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 heater (see Figure 23).

IMPORTANT: Install an equipment shutoff valve in an accessible location. The equip- ment shutoff valve is for turning on or shut- ting 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.

CONNECTING TO GAS SUPPLY

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

WARNING: Never connect fireplace to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

IMPORTANT: Check gas line pressure be- fore connecting fireplace to gas line. Gas line pressure must be no greater than 14 inches of water. If gas line pressure is higher, fireplace regulator damage could occur.
