OPERATION

Continued

to the PILOT position. Press in control knob 

for five (5) seconds (see Figure 22).

 

Note: You may be running this heater for 
the first time after hooking up to gas sup

-

ply. If so, the control knob may need to be 
pressed in for 30 seconds or more. This will 
allow air to bleed from the gas system.

6.  With thermostat control knob pressed in, 

press and release ignitor button. 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,

onds after lighting pilot. After 30 seconds, 

release control knob.

• If control knob does not pop out when 

released,  contact  a  qualified  service 

person or gas supplier for repairs.

 

Note:  If  pilot  goes  out,  repeat  steps  3 
through 7. This heater has a safety inter-
lock system. Wait one minute for system 
to reset before lighting pilot again.

8.  Turn control knob counterclockwise

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 de-

pending 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.
