OPERATING HEATER

Continued

6.With control knob pressed in, press and release ignitor but- ton. This will light pilot. The pilot is attached to the front burner. If needed, keep pressing ignitor button until pilot lights.

Note: If pilot does not stay lit, contact a qualified service person or gas supplier for repairs. Until repairs are made, light pilot with match. To light pilot with match, see Manual Lighting Procedure.

7.Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob.

Note: If pilot goes out, repeat steps 3 through 7. This heater has a safety interlock system. Wait one (1) minute for sys- tem to reset before lighting pilot again.

8.Turn control knob counterclockwise C-clockwiseto desired heating level. The burners should light. Set control knob to any heat level between HI and LO.

CAUTION: Do not try to adjust heating levels by using the equipment shutoff valve.

Shutting Off Heater

Turn control knob clockwise Clockwise to the OFF position.

Shutting Off Burners Only (pilot stays lit)

Turn control knob clockwise Clockwise to the PILOT position.

THERMOSTAT

CONTROL OPERATION

The thermostat control knob can be set to any comfort level between HI and LO. The thermostat will gradually modulate the heat output and flame height from higher to lower settings, or pilot, in order to maintain the comfort level you select. The ideal comfort setting will vary by household depending upon the amount of space to be heated, the output of the central heating system, etc. Note: Selecting the HI setting with the control knob will cause the burners to remain fully on, without modulating down in most cases.

MANUAL LIGHTING

PROCEDURE

1.Follow steps 1 through 5 under Lighting Instructions, page 19.

2.Depress control knob and light pilot with match.

3.Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Now follow step 8, under Lighting Instructions, column 1.

INSPECTING BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 39 shows a correct pilot flame pattern. Figure 40 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 40

•turn heater off (see To Turn Off Gas to Appliance, page 18 [manually-controlled models] or column 1 [thermostat-con- trolled models])

•see Troubleshooting, pages 22 through 24

Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.
