This will begin the highly efficient mode of operation where
the exhaust gases get re-burned in the secondary combustion
package. If you cannot achieve a charcoal bed within the first
15 to 20 minutes, your wood is likely too wet, and you may
need to burn the fire longer and/or hotter to compensate for
the extra energy needed to drive out the moisture. If, after
five minutes of burning with the damper closed, smoke is
visible coming from the chimney, you probably do not have
the proper coal bed. Open the bypass damper and continue
with the process until a significant coal bed is formed.
Install a magnetic probe stack thermometer 24" above the
flue collar of the unit. With the thermometer at this location,
the following guidelines can be helpful if followed; however,
remember these are only rough guidelines and a myriad
of other factors contribute to the operation of the Harman
®
Oakleaf wood stove. While establishing a coal bed, prior
to engaging the Firedome, a 2-3” coal bed and a stack
temperature of 900°F - 1100°F indicate that the stove is
normally ready for Firedome mode. With the Firedome
engaged, temperatures of 500°F – 800°F indicate the
unit is burning properly and no adjustment is necessary.
Temperatures below 400°F with wood remaining in the
firebox indicate the Firedome system is not working and the
stove is likely smoking. Open the damper, and allow the unit
to burn with the damper open for 10-15 minutes to reheat
before attempting to reengage the Firedome system. Lastly,
temperatures above 1000°F with the Firedome engaged
indicate the unit is being over-fired. Unit damage may occur
from operating the unit at stack temperatures above 1000°F.
If, after five minutes of burning with the damper closed, smoke
is visible coming from the chimney, you probably do not have
the proper coal bed. Open the bypass damper and continue
with the process until a significant coal bed is formed.
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, adding fuel
and closing the door then the damper. This depends on coal
bed size, load size and moisture content of fuel.
Removing Ashes:
Before reloading, empty the ash pan
(remember to close the ash door while emptying the pan).
The ashes should be the coolest at this time. Remove ashe
s
from the fire chamber periodically by raking a poker across
the bottom grates.
Excessive ash buildup can prevent proper venting of exhaust
gases. Do not allow the ash pan to over-fill. Ash buildup
between the ash pan and the bottom of the grate can cause
the grate to overheat and wear out prematurely.
Avoid overfiring your stove. Overfiring is a potentially
hazardous situation which can lead to overheating of
combustible materials nearby, damage to the stove, and
in extreme cases, cause a fire. Overfiring is caused by: 1.
Too much air flowing through the stove too quickly. 2. You
may have positioned the primary air control lever too far to
the right. 3. Inadvertently leaving the damper open or 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 stove or chimney connector to glow red.
If you notice signs of overfiring, reduce the air supply to the
fire, and review the Maintenance section in this manual.
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 stove 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 stove
damage and create an even more dangerous situation. Have
your chimney professionally cleaned and inspected before
resuming burning in your stove.
As you begin to operate your stove at higher temperatures,
you will notice a “hot” or unpleasant smell; this is just the
paint going through the curing process, and will disappear
after a few fires.
The Oakleaf is designed to provide access to the ash pan without
the need for opening the main door. Before opening the ash door
and removing the ash pan, open the bypass damper. Wearing
heavy protective gloves, open the ash door and remove the ash
pan by pulling it forward by the handle. Close the ash door and
damper bypass before taking the ashes outside for safe disposal.
Ashes should be placed in a metal container with a tight
fitting lid. The closed container of ashes should be placed
on a noncombustible floor or on 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 thoroughly cooled.
Never use the ash disposal container for other trash. Wood ash
can be added to your garden or compost.
THE STOVE IS HOT WHILE IN OPERATION. KEEP
CHILDREN, CLOTHING AND FURNITURE AWAY.
CONTACT MAY CAUSE SKIN BURNS.
NEVER LEAVE THE STOVE UNATTENDED IF EITHER
THE ASH OR LOAD DOOR IS OPEN. OVERFIRING
MAY RESULT.
RISK OF EXCESSIVE TEMPERATURES. KEEP ASH
DOOR CLOSED DURING FIRING OF THE HEATER.
