INSTALLATION

Continued

Extension Cord

Use extension cord if needed. The cord must have a three-prong, grounding plug and a three-hole recep- tacle. Make sure cord is in good shape. It must be heavy enough to carry the current needed. An under- sized 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 package is pro- vided with fireplace.

1.Drill holes at marked locations using 5/16" drill bit. For solid floors (concrete or ma- sonry), 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 fastened to floor.

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.

CAUTION:Neverconnectpro- pane/LP fireplace directly to the propane/LPsupply.Thisfireplace requiresanexternalregulator(not supplied).Installtheexternalregu- lator between the fireplace and propane/LP supply.

WARNING: Never connect natural gas fireplace to private (non-utility) gas wells. This gas is commonlyknownaswellheadgas.

For propane/LP units, installer must supply an external regulator. The external regulator will re- duce incoming gas pressure. You must reduce in- coming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pres- sure, fireplace regulator damage could occur. In- stall external regulator with the vent pointing down as shown in Figure 22. Pointing the vent down protects 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 volume will occur.
