3.2.6 Accelerated Combustion
The maximum heat output for the BIS
TRADITION is achieved by burning with
the door closed and the combustion air
opened and pulled back. Through this
method, the BIS TRADITION can
produce up to 70 000 BTU of heat per
hour.
However, it will be necessary to reload with wood every one or two hours. This is the least
efficient method of burning the BIS TRADITION.
Use caution when firing with the combustion air control wide open. Only burn cordwood in
this manner. Small dry pieces of softwood and construction scraps will burn very intensely
using this method and may damage the firebox.
3.2.7 Medium Combustion
This is the recommended mode of operating
the BIS TRADITION and should be the
one normally used since it will deposit the
least amount of creosote on the glass and in
the chimney. The combustion air control
must be 3/4 closed .The precise setting will
depend on many factors, including chimney
length and the moisture content of the wood.
For instance, a long chimney will necessitate closing the damper more. To obtain the proper
combustion, close the damper completely, then open it about 1/4" to _". Three medium size
pieces of cordwood burning on a bed of hot coals will generate an approximate heat output
will of 35 000 BTU per hour and the loading time will be about every 3-4 hours. Softwoods
may be burned using this method but the combustion time will be substantially reduced.
3.2.8 Slow Combustion
When the air combustion control is
completely closed, the fireplace is in a slow
combustion phase. If the hearth is hot
enough, slow combustion will not stop the
fire, but there will be a noticeable change in
the flame pattern. The flames will be slow
and may appear dirty if the wood is too
wet (moisture content of 20% and more)
Do not allow the wood to burn without flame, since this will produce excessive creosote in
the unit. Creosote may accumulate on the glass door. This method of burning should be used
only after operating the BIS TRADITION with the air control opened to produce a hot fire
for about an hour or at medium pace for at least 3 hours. Slow combustion can be used at
