Providing you have the charcoal bed described, close the
bypass damper by pulling the handle toward the front of the
stove. 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

TL300
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.
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 ashes
from the fire chamber periodically by raking a poker across
the bottom grates.
Excessive ash buildup can prevent proper venting of exhaust
gases. D
o 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 TL300 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.
DISPOSAL OF ASHES;
Ashes should be placed in a steel container with
a tight fitting lid. The container of ashes should
be moved outdoors 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.
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.
