Lighting Instructions  

 

1.  STOP! Read the safety information above. 

 

2.  Set the thermostat to

 "OFF" 

position. 

 

3.  Unplug the fan accessory, if so equipped. 

 

4.  Push in and turn gas control knob clockwise  

to "OFF" 

 

5.  Wait (5) five minutes to clear out any gas.  If 

you then smell gas, 

STOP!  

Smell all around 

the appliance  for gas.  Be sure to smell next 

to the floor because some gases are heavier 

than air and will settle on the floor.  If you 

smell gas immediately follow the 

What To Do 

If You Smell Gas Warning 

on the cover of 

this manual.  If you do not smell gas, go to 

the next step. 

 

6.  Turn knob on gas control counterclockwise to 

"PILOT".

 

 

7.  Push in control knob all the way and hold in.  

Immediately light the pilot with the gas lighter 

[push in and  "click" the  piezoelectric spark 

igniter button] (This can be found after 

opening the gas control door on the lower 

right side of the unit) Continue to hold the 

control knob in for about 20 seconds after the 

pilot is lit.  Release knob and it will pop back 

out.  Pilot should remain lit.  If the pilot goes 

out, repeat the operation. 

 

!  If knob does not pop out when released, 

stop and immediately call your service 
technician or gas supplier. 

 

!  If the pilot will not stay lit after several tries, 

turn the gas control knob "OFF" and call 
your service technician or gas supplier.  

 

8.  Shut the gas control valve access door. 

 

9. 

Turn gas control knob counterclockwise to

 

"ON". 

 

10.  Plug in fan accessory, if so equipped. Select 

“ON”

 of the on/off/T-stat switch, or if 

“T-stat” 

is selected. 

 

11.  Set thermostat to desired setting. 

 

 

To Turn Off Gas To Appliance

 

 

1.  Set thermostat to 

OFF 

position, or select the 

“OFF”

 position of the on/off/T-stat switch. 

2.  Turn off all electric power to the appliance if 

service is to be performed.  Unplug 
accessory fan (if equipped). 

3.  If shutting the unit for the non-heating 

season, turn gas control knob fully clockwise 
to 

"OFF"

.  Do not force. 

 
 

As a supplement to the above instructions: 

 

When pressing/clicking the piezoelectric spark 
ignition button to light the pilot light, watch through 
the glass front door of the unit.  Click the ignitor 
button until a flame is visible at the pilot light and 
once lit, continue to press on the gas control knob 
for another 20 seconds, then release.  Ascertain that 
the pilot light is still lit by looking through the front 
door.  If lit, then turn the gas control knob fully 
counterclockwise to the 

ON

 position.  If the pilot light 

failed to light or if it went out due to a premature 
release of the gas control knob while pressed in the

 

PILOT

 position, wait 60 seconds for interlock to 

release, then repeat the lighting process as 
described above. 
 

 

WARNING:

 

THE CONTROL HAS AN INTERLOCK 

DEVICE.  AFTER SHUTTING OFF ALL GAS FLOW, 
THE PILOT BURNER CANNOT BE RELIT UNTIL 
THE THERMOCOUPLE HAS COOLED, ALLOWING 
THE ELECTROMAGNET TO BE RELEASED 
(APPROX. 60 SEC.).  THE GAS CONTROL KNOB 
IS DESIGNED TO BE OPERATED BY HAND.  DO 
NOT USE ANY TOOLS DURING THIS OPERATION.  
DAMAGED KNOBS MAY RESULTS IN SERIOUS 
INJURY. 

 

Once the pilot light has been lit, the main burners 

are lit moving the thermostat to a high setting so that 
it "calls" for heat (i.e. turns the unit on).  The main 
burners should light immediately.  Note that the 
on/off cycling of the main burners are controlled by 
the thermostat but that the pilot light remains lit 
regardless of the thermostat setting.  To turn the 
pilot light off, turn the gas control valve fully 
clockwise to the 

OFF

 position. 

 

Once the unit is lit, observe the flame pattern and 

adjust as necessary per the following instructions 
while keeping in mind the off-gassing and break-in 
warnings listed above.
