Thisprovides a clean burning flame. Keep theseholes clear of dust, dirt, and lint. Clean theseair inlet holes prior to each heating season.Blocked air holes will create soot. We rec-ommend that you clean the unit every 2,500hours of operation or every three months.We also recommend that you keep the burnertube and pilot assembly clean and free ofdust and dirt. To clean these parts we recom-mend using compressed air no greater than30 PSI. Your local computer store, hard-ware store, or home center may carry com-pressed air in a can. You can use a vacuumcleaner in the blow position. If using com-pressed air in a can, please follow the direc-tions on the can. If you don't follow direc-tions on the can, you could damage the pilotassembly.1. Shut off the unit, including the pilot.Allow the unit to cool for at least thirtyminutes.2. Inspect burner, pilot, and primary airinlet holes on injector holder for dustand dirt (see Figure 48).3. Blow air through the ports/slots andholes in the burner.Figure 48 - Injector Holder On OutletBurner Tube4. Check the injector holder located at theend of the burner tube again. Removeany large particles of dust, dirt, lint, orpet hairs with a soft cloth or vacuumcleaner nozzle.5. Blow air into the primary air holes onthe injector holder.6. In case any large clumps of dust havenow been pushed into the burner repeatsteps 3 and 4.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 49). With the unit off, lightlyblow air through the air inlet hole. You mayblow through a drinking straw if compressedair is not available.BurnerTubeInjector HolderPrimary Air InletHolesFigure 49 - Pilot Inlet Air HolePilot AssemblyPilot Air InletHolePorts/Slots
