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 15.

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 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 manual 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 17).

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.

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

Install sediment trap in supply line as shown in Figure 17. Locate sediment trap where it is within reach for cleaning. 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

NOTICE: A qualified service per- son must connect fireplace to gas supply. Follow all local codes.

Manual background CAUTION: Never connect fire- place directly to the propane sup- ply. This fireplace requires an ex- ternal regulator (not supplied). In- stalltheexternalregulatorbetween the fireplace and propane supply.

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 incom- ing gas pressure, fireplace regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure

16.Pointing the vent down protects it from freezing rain or sleet.
