OPERATING HEATER
Continued
Shutting Off Heater
Turn control knob clockwise to the OFF position.
Shutting Off Burners Only (pilot stays lit)
Turn control knob clockwise to the PILOT position.
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 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
WARNING: If you do not follow these instructions
exactly, a fire or explosion may result causing prop-
erty damage, personal injury or loss of life.
A. This appliance has a pilot which must be lighted by hand.
When lighting the pilot, follow these instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area
for gas. Be sure to smell next to the floor because some gas
is heavier than air and will settle on the floor.
WARNING:
• If fireplace has glass doors, never operate this
heater with glass doors closed. If you operate
heater with doors closed, heat buildup inside fire-
place will cause glass to burst. Make sure there are
no obxtructions across openings of fireplace.
• You must operate this heater with a fireplace screen
in place. Make sure fireplace screen is closed
before running heater.
NOTICE: During initial operation of new heater, burn-
ing logs will give off a paper-burning smell. Orange
flame will also be present. Open damper or window to
vent smell. This will only last a few hours.
Note:
Home owners generally prefer to operate their heater
with the chimney damper closed. This will put all the heat into
the room. However, there may be times you will desire the full
flames of the High heat setting but will find the heat output
excessive. You can open the chimney damper (if you have one)
fully or partially to release some of the heat.
WARNING: Damper handle will be hot if heater has
been running.
1. STOP! Read the safety information starting in column 1.
2. Make sure equipment shutoff valve is fully open.
3. Press in and turn control knob clockwise to the
OFF position.
