Always remember to open the bypass damper when you are
loading, this allows the exhaust gases to pass directly into
the flue outlet and reduces the chance of smoke spillage
into the room.
Reloading:
Once you have prepared and maintained a thick
charcoal bed, and the secondary combustion is established,
you should be able to reload the stove at any time by simply
opening the bypass damper, then the load door, add fuel and
close the door then the damper. Depending on coal bed size,
load size and moisture content of fuel, you may need to burn
for a short period with the damper open and an increased
air control setting.
removing ashes:
Do not allow ashes to accumulate more
than 2" - 3" in depth. Excessive ash buildup can restrict air
flow through the firebox. This will prevent proper venting of
exhaust gases.
ashes should be placed in a steel container with a tight
fitting lid. the container of ashes should be moved outside
immediately, and placed on a noncombustible floor or
the ground, well away from all combustible materials,
pending final disposal. If the ashes are disposed of by
burial in soil or otherwise locally dispersed, they should
be retained in the closed container until all cinders have
completely cooled. other waste shall not be placed in
this container.
Never use the ash disposal container for other trash. Wood
ash can be added to your garden or compost
Before opening the door for ash removal, open the bypass
damper. Using a fire rake, scrape the hot coals to one side
of the firebox and the ashes to the other. Scoop the ashes
out into the metal container as described above. Once the
majority of ashes are removed, spread the hot coals back
out across the bottom of the firebox and add the appropriate
sized fuel to retain the fire. Close the door before taking the
ashes outside for safe disposal.
Medium-high burn rate -
air control set between the second
and third notch. This setting may be used to burn wood that is
damp in order to keep it burning, but will consume seasoned,
dry wood very fast.
high burn rate
- air control fully to the right. This setting is
for refueling and starting a fire.
Continuous burning at this
setting will cause premature failure of consumable parts such
as the "FireDome and/or the firebricks.
If continuous burning
at maximum setting is needed, the appliance is too small for
the space you are heating, or the wood fuel is too wet.
note: at minimum burn rates the glass may get dirty but
will clean itself off again at higher burn rates.
contact may cause skin burns.
overfiring
Avoid overfiring your insert. Overfiring is a potentially
hazardous situation which can lead to overheating of
combustible materials, damage to the insert, and in extreme
cases, cause a fire. Overfiring is caused by:
1. Too much air flowing through the insert too quickly.
2. You may have positioned the primary air control lever too
far to the right.
3. You may have, inadvertently, left the damper open.
4. Not keeping up with routine maintenance, such as
checking door gaskets for wear.
Overfiring results in excessive fuel consumption, and may
cause parts of the insert to glow red. If you notice signs of
overfiring, reduce the air supply to the fire, and review the
Maintenance section in this manual.
never leave the insert unattended with the door open.
overfiring may result.
In the event of a chimney fire, call your local fire department;
make sure everyone is safely out of the house. Reduce the
air intake of the insert as much as possible using the air
control lever; close the bypass damper to further restrict air
flow. Do not throw water on the fire; this can cause insert
damage and create an even more dangerous situation. Have
your chimney professionally cleaned and inspected before
resuming burning in your insert.
