This provides aclean burning flame. Keep these holes clear of dust,dirt and lint. Clean these air inlet holes prior to eachheating season. Blocked air holes will create soot.We recommend that you clean the unit every threemonths during operation and have heater inspectedyearly by a qualified service person.We also recommend that you keep the burnertube and pilot assembly clean and free of dust anddirt. To clean these parts we recommend usingcompressed air no greater than 30 PSI. Your localcomputer store, hardware store or home center maycarry compressed air in a can. If using compressedair in a can, please follow the directions on the can.If you don't follow directions on the can, you coulddamage the pilot assembly.1. Shut off the unit, including the pilot. Allowthe unit to cool for at least thirty minutes.2. Inspect burner, pilot for dust and dirt.3. Blow air through the ports/slots and holes inthe burner.4. Never insert objects into the pilot tube.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 about twoinches from where the pilot flame comes out ofthe pilot assembly (see Figure 24). With the unitoff, lightly blow air through the air inlet. You mayblow through a drinking straw if compressed airis not available.Figure 24 - Pilot Air Inlet HolePilot AssemblyPilot Air InletCABINETAir PassagewaysUse pressurized air to clean.ExteriorUse a soft cloth dampened with a mild soap andwater mixture.
