OPERATING HEATER

Continued

MANUAL LIGHTING

PROCEDURE

1.Remove lower front panel (see Figure 7 page 7).

2.Follow steps through 5 under Lighting Instructions on page12.

3.With control knob pressed in, strike match. Hold match to pilot until pilot lights.

4.Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob.Follow step 8 under Lighting Instuctions on page 12.

5.Replace lower front panel.

INSPECTING BURNER

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 24 shows a correct pilot flame pattern. Figure 25 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching 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 25.

turn heater off (see To Turn Off Gas to Appliance. page 11,12 see Troubleshooting. pages 14 through 16.

BURNER FLAME PATTERN

Figure 26 shows a correct burner flame pattern. Figure 26 shows an incorrect burner flame pattern.

If burner flame pattern is incorect, as shown in Figure 27

turn heater off (see To Turn Off Gas to Appliance pages 11&12) see Troubleshooting (pages 14 through 16)

ODS/PILOT AND BURNER

Use a vacuum cleaner, pres- surized air, or a 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 recommend using compressed air no greater than 30 PSl. Your local computer store, hardware store. or home cen- ter may carry compressed 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 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, and pilot for dust and dirt.

3.Blow air through the ports/slots

and holes in the bumer.

Also clean the pilot assembly. A yellow tip on the pilot flame indi- cates 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 28). 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.

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 excessive lint from carpeting, bedding material, pet hair, etc.

CABINET

Air Passageways

Use a vacuum cleaner or pressurized air to clean.

Exterior

Use a soft cloth dampened with a mild soap and water mixture. Wipe the cabinet to remove dust.
