INSPECTING

BURNER

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 17 shows a correct pilot flame pattern. Figure 18 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 18

turn heater off (see To Turn Off Gas to Appliance, page 11)

seeTroubleshooting, pages 13 through 15

BURNER FLAME PATTERN

Figure 19 shows a correct burner flame pattern. Figure 20 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows yellow tipping of the flame. It also shows the flame higher than 1/2 the glass panel height.

NOTICE: Do not mistake orange flames with yellow tipping. Dust or other fine particles enter the heater and burn causing brief patches of orange flame.

CLEANING AND MAINTENANCE

WARNING: Turn off heater and let cool before cleaning.

CAUTION: You must keep control areas, burner, and circu- lating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a quali- fied service person. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.

CLEANING BURNER PILOT AIR INLET HOLE

We recommend that you clean the unit every 2,500hoursofoperationoreverythreemonths.

We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air no greater than 30 PSI. Your local computer store, hardware store, or home center may carry compressed air in a can. You can use a vacuum cleaner in the blow position. If using compressed air in a can, please follow the directions on the can. If you don't follow directions 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 21). 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.
