Turn control knob clockwise to the OFF position.

Shutting Off Burners Only (pilot stays lit)

Turn control knob clockwise to the PI- LOT position.

THERMOSTAT CONTROL

OPERATION

The thermostat control knob can be set to any comfort level between HI and LO. The ther- mostat will gradually modulate the heat out- put and flame height from higher to lower set- tings, 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 In- structions, page 14.

2.Depress control knob and light pilot with match.

3.Keep control knob pressed in for 30 sec- onds after lighting pilot. After 30 seconds, release control knob. Now follow step 8 Lighting Instructions, page 14

INSPECTING BURNERS

Check pilot flame pattern and burner flame pat- terns often.

PILOT FLAME PATTERN

Figure 21 shows a correct pilot flame pattern. Figure 22 shows an incorrect pilot flame pattern. The incor-

rect 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 Fig- ure 22

turn heater off (see To Turn Off Gas to Appliance)

see Troubleshooting, pages 18 through 21 Note: The correct pilot flame on natural gas units will have a slight curve, but flame should be blue an have no yellow or orange color.
