INSPECTING
BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 19 shows a correct pilot flame pattern. Figure 20 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touch- ing the thermocouple. This will cause the thermocouple to cool. When the thermo- couple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown in Figure 20
•turn heater off (see To Turn Off Gas to Appliance)
•seeTroubleshooting, pages 14 through 16

CLEANING AND MAINTENANCE
WARNING: Turn off heater and let cool before cleaning.
CAUTION: You must keep con- trol areas, burner, and circulating air passageways of heater clean. Inspect these areas of heater be- fore each use. Have heater in-
ODS/PILOT AND BURNER ORIFICE
•Use a vacuum cleaner, pressurized air, or small, soft bristled brush to clean.
CLEANING BURNER PILOT AIR INLET HOLE
We recommend that you clean the unit every 2,500 hours of operation or every three months.
We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recom- mend using compressed air no greater than 30 PSI. Your local computer store, hard- ware store, or home center may carry com- pressed air in a can. You can use a vacuum cleaner 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 pilot assembly.
1.Shut off the unit, including the pilot. Allow the 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 in the burner.
Clean the pilot assembly also. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see Figure 23). With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if compressed air is not available.

Air Passageways
•Use a vacuum cleaner or pressurized air to clean.
