You mustreduce incoming gas pressure to between 11 and 14 inches of water.If you do not reduce incoming gas pressure, heater regulator damagecould occur. Install the external regulator with the vent pointingdown as shown in Figure 13. Pointing the vent down protects it fromfreezing rain or sleet.WARNING: A qualified service person must con-nect heater to gas supply. Follow all local codes.CAUTION: For propane/LP gas, never connectheater directly to the propane/LP supply. This heaterrequires an external regulator (not supplied). Installthe external regulator between the heater and pro-pane/LP supply.CAUTION: Use only new, black iron or steel pipe.Internally-tinned copper tubing may be used in certainareas. Check your local codes. Use pipe of largeenough diameter to allow proper gas volume to heater.If pipe is too small, undue loss of volume will occur.WARNING: This appliance requires a 3/8" NPT(National Pipe Thread) inlet connection to the pres-sure regulator.IMPORTANT: For natural gas, check gas line pressure beforeconnecting heater to gas line. Gas line pressure must be no greaterthan 14 inches of water. If gas line pressure is higher, heaterregulator damage could occur.WARNING: For natural gas, never connect heaterto private (non-utility) gas wells. This gas is com-monly known as wellhead gas.CONNECTING TO GAS SUPPLYFigure 13- External Regulator With Vent Pointing DownExternalRegulatorPropane/LPSupplyTankVentPointingDownInstalling Bottom Mounting Screws1. Locate two bottom mounting holes. These holes are near bot-tom on back panel of heater (see Figure 12).2. Mark screw locations on wall.3. Remove heater from mounting bracket.4. If installing bottom mounting screws into hollow or solid wall,install wall anchors. Follow steps 1 through 4 under Attaching ToWall Anchor Method, page 9.If installing bottom mounting screw into wall stud, drill holesat marked locations using 9/64" drill bit.5. Replace heater onto mounting bracket.6. Place spacers between bottom mounting holes and wall anchoror drilled hole.7. Hold spacer in place with one hand. With other hand, insertmounting screw through bottom mounting hole and spacer.Place tip of screw in opening of wall anchor or drilled hole.8. Tighten both screws until heater is firmly secured to wall. Donot over tighten.Note: Do not replace front panel at this time. Replace frontpanel after making gas connections and checking for leaks (seepages 11 and 12).
