To clean these parts we recommend usingcompressed air no greater than 30 PSI. Your localcomputer store, hardware store or home centermay carry compressed air in a can. You can use avacuum cleaner in the blow position. If using com-pressed air in a can, please follow the directions onthe can. If you don't follow directions on the can,you could damage the pilot assembly.1. Shut off the unit, including the pilot. Allowthe unit to cool for at least thirty minutes.2. Inspect burner, pilot and primary air inlet holes oninjector holder for dust and dirt (see Figure 31).3. Blow air through the ports/slots and holes inthe burner.4. Check the injector holder located at the endof the burner tube again. Remove any largeparticles of dust, dirt, lint or pet hair with asoft cloth or vacuum cleaner nozzle.5. Blow air into the primary air holes on theinjector holder.6. In case any large clumps of dust have now beenpushed into the burner repeat steps 3 and 4.Clean the pilot assembly also. A yellow tip on thepilot flame indicates dust and dirt in the pilot as-sembly. There is a small pilot air inlet hole about2" from where the pilot flame comes out of thepilot assembly (see Figure 32). With the unit off,lightly blow air through the air inlet hole. You mayblow through a drinking straw if compressed airis not available.Figure 31 - Injector Holder On OutletBurner TubeBurner TubeInjectorHolderPrimary AirInlet HolesPorts/SlotsFigure 32 - Pilot Inlet Air Hole(Propane/LP Shown)Pilot Assembly Pilot Air Inlet HoleCABINETAir PassagewaysUse a vacuum cleaner or pressurized air toclean.ExteriorUse a soft cloth dampened with a mild soap andwater mixture.
