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 20.
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, above.

person or gas supplier for repairs.
