BURNER FLAME PATTERN

WARNING: If yellow tipping occurs, your heater could produce increased levels of carbon monoxide.

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

Figure 23 shows a correct burner flame pattern. Figure 24 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 24

•turn heater off (see To Turn Off Gas To Appliance, page 14)

•see Troubleshooting, pages 17 through 19

CLEANING AND

MAINTENANCE

WARNING: Turn off heater and let cool before cleaning.

CAUTION: You must keep control areas, burner, and circulating air passageways of heater clean. In- spect these areas of heater before each use. Have heater inspected yearly by a qualified service person. Heater may need more frequent cleaning due to exces- sive lint from carpeting, bedding material, pet hair, etc.

WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in soot- ing and property damage.

•Use a vacuum cleaner, pressurized air, or small, soft bristled brush to clean.

CLEANING BURNER PILOT AIR INLET

The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean burning flame. Keep these holes clear of dust, dirt, and lint. Clean these air inlet holes prior to each heating season. Blocked air holes will create soot. We recommend that you clean the unit every three months during operation and have heater inspected yearly by a qualified service person.

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 com- pressed air in a can. You can use a vacuum cleaner in the blow position. If using compressed air in a can, please follow the direc- tions 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.

4.Never insert objects into the pilot tube.

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 about two inches from where the pilot flame comes out of the pilot assembly (see Figure 25). With the unit off, lightly blow air through the air inlet. You may blow through a drinking straw if compressed air is not available.
