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 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, and primary airinlet holes on injector holder for dustand dirt (see Figure 36).3. Blow air through the ports/slots andholes in the burner.4. 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 37). With the unit off, lightlyblow air through the air inlet hole. You mayblow through a drinking straw if compressedair is not available.Figure 36 - Injector Holder On OutletBurner TubeBurnerTubePrimary Air InletHoles (Shape ofHoles May Varyby Model)Figure 37 - Pilot Inlet Air HoleBurnerTubePilot AssemblyPilot AirInlet HolePorts/SlotsInjector Holder(May Be Brass orAluminum De-pending on Model)
