The cord must have a three-prong,grounding plug and a three-hole receptacle. Make sure cord is in goodshape. It must be heavy enough to carry the current needed. Anundersized cord will cause a drop in line voltage. This will result inloss of power and overheating. Use a No. 16 AWG cord for lengthsless than 50 feet.INSTALLATIONContinuedATTACHING WOOD BASE TO SOLID FLOORFor 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 solidfloors (concrete or masonry), drill at least 1" deep.2. Fold floor anchor as shown in Figure 28.3. Insert floor anchor (wings first) into hole. Tap anchor flushto floor.4. Insert mounting screws through base and into floor anchors.5. Tighten screws until base is firmly fastened to floor.Figure 28 - Folding AnchorPropane/LPSupply TankExternal RegulatorCONNECTING TO GAS SUPPLYFigure 29 - External Regulator With Vent Pointing DownVent Pointing DownWARNING: A qualified service person must con-nect fireplace to gas supply. Follow all local codes.CAUTION: Never connect propane/LP fireplacedirectly to the propane/LP supply. This fireplacerequires an external regulator (not supplied). Installthe external regulator between the fireplace and pro-pane/LP supply.For propane/LP units, the installer must supply an external regula-tor. The external regulator will reduce incoming gas pressure. Youmust reduce incoming gas pressure to between 11 and 14 inches ofwater. If you do not reduce incoming gas pressure, fireplaceregulator damage could occur. Install external regulator with thevent pointing down as shown in Figure 29. Pointing the vent downprotects it from freezing rain or sleet.WARNING: This appliance requires a 45° male flarefitting 5/8"-18 UNF (Unified National Fine Thread) inletconnection and the flexible gas line provided.WARNING: Never connect natural gas fireplace toprivate (non-utility) gas wells. This gas is commonlyknown as wellhead gas.INSTALLATIONInstalling Blower Accessory GA3450T in Thermostat-Controlled Models (Cont.)Attaching Wood Base to Solid FloorConnecting to Gas SupplyIMPORTANT: For natural gas, check gas line pressure beforeconnecting fireplace to gas line. Gas line pressure must be no greaterthan 14 inches of water. If gas line pressure is higher, heater regulatordamage could occur.
