INSPECTING

BURNER

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 18 shows a correct pilot flame pat- tern. Figure 19 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown in Figure 19

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

•seeTroubleshooting, pages 13 through 15

Pilot Burner

WARNING: If yellow tipping occurs, your heater could pro- duce increased levels of carbon monoxide. If burner flame pattern shows yellow tipping, follow in- structions at bottom of this page.

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 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.

BURNER FLAME PATTERN

Figure 20 shows a correct burner flame pattern. Figure 21 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.

If burner flame pattern is incorrect, as shown in Figure 21

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

•seeTroubleshooting, pages 13 through 15

Yellow

Tipping 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 HEIGHT (see Figure 22). 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.
