We recommend thatyou clean the unit every three months duringoperation and have heater inspected yearlyby a qualified service person.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. If using compressed air in a can, pleasefollow the directions on the can. If you don’tfollow directions on the can, you could dam-age 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 and holesin the burner.4. Never insert objects into the pilot tube.Clean the pilot assembly also. A yellow tip onthe pilot flame indicates dust and dirt in thepilot assembly. There is a small pilot air inletabout two inches from where the pilot flamecomes out of the pilot assembly (see Figure33). With the unit off, lightly blow air throughthe air inlet. You may blow through a drinkingstraw if compressed air is not available.Pilot AssemblyCABINETAir PassagewaysUse pressurized air to clean.ExteriorUse a soft cloth dampened with a mild soapand water mixture.
