Figure 21 shows an incorrect burnerflame pattern. The incorrect burner flamepattern shows yellow tipping of the flame. Italso shows the flame higher than 1/2 theglass panel height.If burner flame pattern is incorrect, as shownin Figure 21• turn heater off (see To Turn Off Gas toAppliance, page 11)• see Troubleshooting, pages 13 through 15NOTICE: Do not mistake orangeflames with yellow tipping. Dustor other fine particles enter theheater and burn causing briefpatches of orange flame.WARNING: If yellow tippingoccurs, your heater could pro-duce increased levels of carbonmonoxide. If burner flame patternshows yellow tipping, follow in-structions at bottom of this page.Figure 20 - Correct Burner Flame Pattern1/2 GLASS1/2 GLASSFigure 21 - Incorrect Burner Flame PatternYellowTippingCLEANING ANDMAINTENANCEWARNING: Turn off heaterand let cool before cleaning.CAUTION: You must keepcontrol areas, burner, and circu-lating air passageways of heaterclean. Inspect these areas ofheater before each use. Haveheater inspected yearly by a quali-fied service person. Heater mayneed more frequent cleaning dueto excessive lint from carpeting,bedding material, pet hair, etc.INSPECTINGBURNERCheck pilot flame pattern and burner flamepattern often.PILOT FLAME PATTERNFigure 18 shows a correct pilot flame pat-tern. Figure 19 shows an incorrect pilotflame pattern. The incorrect pilot flame isnot touching the thermocouple. This willcause the thermocouple to cool. When thethermocouple cools, the heater will shutdown.If pilot flame pattern is incorrect, as shownin Figure 19• turn heater off (see To Turn Off Gas toAppliance, page 11)• see Troubleshooting, pages 13 through 15GRH/OV 007GOOD PILOT/LPThermocouplePilot BurnerFigure 18 - Correct Pilot Flame PatternHEIGHTODS/PILOT AND BURNERORIFICE• Use a vacuum cleaner, pressurized air,or small, soft bristled brush to clean.HEIGHTCABINETAir Passageways• Use a vacuum cleaner or pressurized airto clean.Exterior• Use a soft cloth dampened with a mildsoap and water mixture. Wipe the cabi-net to remove dust.CLEANING BURNERPILOT AIR INLET HOLEWe recommend that you clean the unit every2,500 hours of operation or every three months.We also recommend that you keep the burnertube and pilot assembly clean and free of dustand dirt. To clean these parts we recommendusing compressed air no greater than 30 PSI.Your local computer store, hardware store, orhome center may carry compressed air in acan. You can use a vacuum cleaner in theblow position. If using compressed air in acan, please follow the directions on the can.If you don't follow directions on the can, youcould damage the pilot assembly.1. Shut off the unit, including the pilot.Allow the unit to cool for at least thirtyminutes.2. Inspect burner, pilot for dust and dirt.3. Blow air through the ports/slots andholes in the burner.Clean the pilot assembly also. A yellow tipon the pilot flame indicates dust and dirt inthe pilot assembly. There is a small pilot airinlet hole about two inches from where thepilot flame comes out of the pilot assembly(see Figure 22). With the unit off, lightlyblow air through the air inlet hole. You mayblow through a drinking straw if compressedair is not available.Figure 22 - Pilot Inlet Air HolePilot AssemblyPilot Air Inlet Hole
