ULTRA FLAME DV “0” Clearance Fireplace
ADJUSTING AIR SHUTTER
To adjust the air shutter there is an adjustment screw. The factory setting for the air shutter is
3/16” 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 glass front,
the logs and grate. Lift out the hearth surrounding the burner and the shutter will be exposed
underneath.
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 fireplace 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.
