ADJUSTING AIR SHUTTER
To adjust the air shutter there is an adjustment band below the firebox floor. The factory
setting for the air shutter is 1/8” for natural gas, ¼” for propane. After operating the appliance
for half an hour or so the flames should have turned a nice yellow colour. However, in higher
altitudes you may find a smudging up of the glass after a few days. The shutter should then be
adjusted open in 1/16” increments until the glass stays clear. If the flame does not turn yellow
the air shutter should be closed until the flame just turns yellow. To access the shutter you need
to remove the front surround with the louvres. The shutter adjustment band is directly in the
center under the firebox.
WALL THERMOSTAT
The optional wall thermostat will automatically keep your room at an even temperature. You
need to choose a convenient location for the thermostat. Remember that it should be at least 10
feet from the insert and away from direct radiation of the fire. Run the correct gauge wire (see
table) from the valve to the thermostat and wire as shown in the diagram.
