MANUAL LIGHTING

PROCEDURE

1.Follow steps 1 through 5 under Light- ing Instructions, page 12.

2.With control knob pressed in, strike match. Hold match to pilot until pi- lot lights.

3.Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Follow steps 8 and 9 under Lighting Instruc- tions, page 12.

INSPECTING

BURNER

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 21 shows a correct pilot flame pattern. Figure 22 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 22

turn heater off (see To Turn Off Gas to Appliance, page 11 for non-thermostat models or page 12 for thermostat model)

WARNING: If yellow tipping occurs, your heater could pro- duce increased levels of carbon monoxide. If burner flame pat- tern shows yellow tipping, follow instructions below.

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.

If burner flame pattern is incorrect, as shown in Figure 24

turn heater off (see To Turn Off Gas to Appliance, page 11 for non-thermostat models or page 12 for thermostat model)

CLEANING AND MAINTENANCE

WARNING: Turn off heater and let cool before cleaning.

ODS/PILOT AND BURNER

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 2,500hoursofoperationoreverythreemonths.

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 25). 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.
