INSTALLATION

Extension Cord

Use extension cord if needed. The cord must have a three-prong, grounding plug and a three-hole receptacle. Make sure cord is in good shape. It must be heavy enough to carry the current needed. An undersized cord will cause a drop in line voltage. This will result in loss of power and overheating. Use a No. 16 AWG cord for lengths less than 50 feet.

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.

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.

Attaching Wood Base to Solid 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 allow proper gas volume to fireplace. If pipe is too small, undue loss of pressure will occur.

External Regulator

Propane/LP

Supply Tank

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 23).

IMPORTANT: Install main gas valve (manual shutoff valve) in an accessible location. The main gas 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.

CONNECTING TO GAS SUPPLYCAUTION: Use pipe joint seal- ant that is resistant to liquid pe- troleum (LP) gas.

Install sediment trap in supply line as shown in Figure 23. 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

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

Manual backgroundCAUTION: 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.
