8102393PROPANE/LP GAS HEATERBLUE FLAME 10,000 BTU IMPORTANT: Hold pressure regulatorwith wrench when connecting it to gaspiping and/or fittings.Figure 13 - Gas Connection* An A.G.A. design-certified manual shutoff valve with 1/8" NPT tap is an acceptablealternative to test gauge connection. Purchase the optional A.G.A. design-certified manualshutoff valve from your dealer.

Follow all local codes.The installer must supply an external regu-lator. The external regulator will reduceincoming gas pressure. You must reduceincoming gas pressure between 11 and 14inches of water. If you do not reduce incom-ing gas pressure, heater regulator damagecould occur. Install external regulator withthe vent pointing down as shown in Figure12. Pointing the vent down protects it fromfreezing rain or sleet.CAUTION: Never connectheater directly to the propane/LPsupply. This heater requires anexternal regulator (not supplied).Install the external regulator be-tween the heater and propane/LPsupply.Propane/LPSupply TankFigure 12 - External Regulator With VentPointing DownVentPointingDownExternalRegulatorInstall sediment trap in supply line as shownin Figure 13. Locate sediment trap where itis within reach for cleaning. Locate sedi-ment trap where trapped matter is not likelyto freeze. A sediment trap traps moistureand contaminants. This keeps them fromgoing into heater controls. If sediment trapis not installed or is installed wrong, heatermay not run properly.Installation must include a manual shutoffvalve, ground joint union, and plugged1/8" NPT tap. Locate NPT tap within reachfor test gauge hook up. NPT tap must beupstream from heater (see Figure 13).Apply pipe joint sealant lightly to malethreads. This will prevent excess sealantfrom going into pipe. Excess sealant in pipecould result in clogged heater valves.CAUTION: Use only new,black iron or steel pipe. Inter-nally-tinned copper tubing maybe used in certain areas. Checkyour local codes. Use pipe 3/8"diameter or greater to allowproper gas volume to heater. Ifpipe is too small, undue loss ofpressure will occur.CAUTION: Use pipe joint seal-ant that is resistant to liquid pe-troleum (LP) gas.
