To determine if the air shutter needs
adjustment, it is necessary to view the flame
pattern with the variable output control knob
at its highest setting. Allow the unit to
operate for at least 10 minutes to allow the
entire unit to reach temperature, and for the
flame pattern to stabilize. Generally, the
more air (open shutter) in the mixture, the
bluer the flame. Less air (closed shutter)
results in a more yellow flame, but too little
air will result in incomplete combustion, low
efficiency and a dirty burn. There are two
simple guidelines to aid in determining the
correct flame pattern:
1.
If the flame at the base of the logs is
completely blue, the air shutter may
be open too far;
2.
If the flame is dirty or licks the top
of the stove, the air shutter may be
closed too far.
Some conditions cannot be corrected
through air shutter adjustment; an
adjustment must be made to the gas supply
pressure or by changing the restriction plate
location. Qualified service personnel must
perform supply line/manifold gas line
pressure adjustments and restrictor plate
adjustments. Do not attempt to complete any
part of the installation or adjustment of this
unit unless technically qualified to do so.

NOTE:
The gas control knobs and the piezo
igniter are located behind the control valve
access door, under the front of the unit.
1.
STOP! Read the What To Do If You
Smell Gas! Warning (on the cover of
this manual).
2.
Set the on/off/T’stat switch or thermostat
to the “OFF” position.
3.
Unplug the fan accessory, if so
equipped.
4.
Push in and turn gas control knob
clockwise to “OFF”.
(If not previously
lit, the knob should be in this position.)
5.
Wait (5) five minutes to clear out any
gas. If you then smell gas, STOP!
Smell
all around the appliance area 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,
proceed to the next step.
6.
Turn gas control knob counter-clockwise
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 several
times until lit). Continue to hold the
control knob in for about 20 seconds
after the pilot is lit. Release the 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, shut off the gas supply to the heater
and immediately call a qualified service
technician or gas supplier.
•
If the pilot will not stay lit after several
tries, turn the gas control knob “OFF”
and call a qualified service technician or
gas supplier.
8.
After the pilot lights, turn gas control
knob counter-clockwise to “ON”.
9.
If the ON/OFF/T’stat switch is set to
“ON”, the stove should now be lit. If the
thermostat (or remote) has been
installed, set the ON/OFF/ T’stat switch
to “T’stat” and turn the thermostat (or
remote) to “ON”. Then set the desired
temperature.
