TO TURN OFF GAS TO APPLIANCE

Shutting Off Heater

1. Turn control knob clockwise Clockwise to the OFF position.

Shutting Off Burners Only (pilot stays lit)

1. Turn control knob clockwise Clockwise to the PILOT position.

THERMOSTAT CONTROL OPERATION

(Thermostat-Controlled Models Only)

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 burner to remain fully on, without modulating down in most cases.

MANUAL LIGHTING PROCEDURE

1.Follow steps 1 through 5 under Lighting Instructions, page 23.

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, page 23.

Check pilot flame pattern and burner flame patterns 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 the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.
