Exception TL200 Wood Stove

Air Control
The air control lever is located directly below the ash
lip of the stove. Using this lever you will be able to vary the
amount of air delivered to the fire, creating a range of heat
outputs. The low heat output setting is to the left, and
high is to the far right. Do not, under any circumstances,
alter the configuration or operation of the air control lever.

Less
Below this setting, run the optional blower on "low"
or "OFF". Higher air movement cools the
secondary combustion area which can lead to poor
combustion and lower efficiency.
Building and Maintaining the Fire
The Harman Exception was tested with the fuel door
open and closed. If you operate under normal conditions
keep door closed.
Set the air control lever at the maximum heat output
setting, all the way to the right. Open the bypass damper
by moving the top loading handle forward one position (ap-
proximately 3"). The convection blower, if installed, should
be off for the first five minutes after a reload.
Never use gasoline, gasoline-type lantern fuel,
kerosene, charcoal lighter fluid, or similar liquids to
start or “freshen up” a fire in this heater. Keep all
such liquids well away from the heater while it is in
use.
Build a bed of paper and kindling; place several 1
" - 2" (25 mm - 50 mm) split pieces of dry wood on top,
followed by a few 2" - 3" (50 mm - 80 mm) split pieces.
Ignite the paper a nd close the door.
Allow the fire to burn until a good charcoal bed, 2" -
3" (50 mm - 80 mm) is formed; close the bypass damper
by pushing the top loading handle all the way back until it
locks closed. (You may need to leave the load door open
a crack to get the blaze going properly, but never leave the
stove unattended with door open.) Add more wood to cre-
ate a deeper charcoal base (3" - 4", or 80 mm - 100 mm
thick); remember to open the bypass damper if you are
loading from the front. This will allow the exhaust gases to
pass directly into the flue outlet and reduce smoke spill-
age during refueling.
Once the charcoal bed is established you may add
a full load of dry wood. After adding the fuel, leave the
damper open and the air setting at maximum for 5 to 15
minutes; close the damper and allow the air setting to
remain on high for an additional 5 to 10 minutes. Then
adjust the air lever and blower speed for the desired heat
output.
Reloading
Once you have prepared and maintained a thick char-
coal bed, you should be able to reload the stove, allow
some open damper burning at the maximum air setting,
close the damper and reset the air control in about five
minutes.
Blower
To regulate the speed of the optional convection
blower, adjust the control from low to high by turning the
knob located on the blower. The blower speed should be
matched to the air control lever setting.
When the air setting is low, the blower should al-
ways be at the minimum setting (corresponding to a blower
speed of 750 RPM.) At higher settings, above first notch
on the air control, the blower may be set to your desired
comfort level. Be sure that the blower cord does not run
under, over, above or in front of the stove.
