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 25).3. Blow air through the ports/slots andholes in the burner.Figure 25 - Injector Holder On OutletBurner TubeBurnerTubeInjector Holder(May Be Brassor AluminumDepending onModel)Primary Air InletHoles (Shape ofHoles May Varyby Model)BurnerTubePilotAssemblyPilot AirInlet HolePorts/SlotsFigure 26 - Pilot Inlet Air Hole4.
