4. Once the kindling is fully ignited, add another 12 to 15
of kindling, which will be around the same amount as
the initial load.
5. Leave the door slightly open for three to five minutes
(3-5 min) to ensure full ignition of the second kindling
load.
6. After the second load of kindling is fully ignited, you
can close the door and shift the knob on the front
of the unit to AUTO which allows the barometric
damper to function freely. After 15 minutes, fully
open the damper on the combustion fan.
7. Once the kindling burns down to about 8 lbs., which
should be to the point that the kindling will break up
into a full bed of coals, the pre-load can be added into
the firebox. The pre-load should consist of around
40 pounds of properly seasoned cord wood, which
should be about 6 to 8 pieces of wood.
8. After loading the pre-load, close the door, and make
certain the combustion fan is ON.
9. Allow about one hour (1hr) for the pre-load to burn
down to around 10-12 lbs. or when all the pre-load
wood will break up into coals. You should now have a
coal bed that is several inches deep in the bottom of
the firebox.
10. The purpose of the pre-load burn is to establish
a proper coal bed prior to inserting the main load
of wood. Having a proper coal bed is the key to a
complete ignition of the main wood load and to
maintain the correct firebox temperatures to get the
best emissions and efficiency output of the furnace.
11. After you have completed the pre-load burn, you may
insert your main firewood load.
12. The main load should be the same size or amount as
the pre-load, approximately 40 pounds of cord wood,
6 to 8 pieces.
13. Try to keep gaps between the pieces of wood to help
with the ignition and maintain a good fire.
MAIN FIREWOOD LOAD
• Ensure that the combustion fan is ON, and open the
feed door to insert the main firewood load.
• After loading, leave the feed door slightly open for five
minutes (5 min) to ensure proper ignition, then close
the door.
• The damper on the combustion fan should be open.
• Depending on the temperature at which the wall
thermostat is set, this will determine the burn duration
of the main load. A lower setting on the thermostat
should result in a longer burn time as this would allow
the combustion fan to remain OFF for longer periods.
A higher thermostat setting will cycle the combustion
blower ON/OFF more often, resulting in a hotter, but
shorter duration burn time of course. However, colder
outside temperatures and your home's construction
(insulation) will play a big factor in how well the
thermostat can maintain it's set temperature.
VISIBLE SMOKE
The amount of visible smoke being produced can be
an effective method of determining how efficiently the
combustion process is taking place at the given settings.
Visible smoke consist of unburned fuel and moisture
leaving your stove. Learn to adjust the air settings of your
specific unit to produce the smallest amount of visible
smoke. Wood that has not been seasoned properly and
has a high wood moisture content will produce excess
visible smoke and burn poorly. Use the included moisture
meter to ensure your wood has a 20% or less moisture
content.
AIR TUBES
The air tubes assembled in this unit are designed to
provide an accurate mix of secondary air to ensure the
highest efficiency. Any damage or deterioration of these
tubes may reduce the efficiency of combustion. The air
tubes are held in position by screws or snap pins. Locate
these to either side of the tube and remove it to allow the
tube to be removed and replaced.
