2.2.7 Combustion Settings

Accelerated Combustion
The maximum heat output for the ENERZONE SOLUTION 2.5ZC is achieved by burning
with the door closed and the combustion air opened. By this method, the ENERZONE
SOLUTION 2.5ZC can produce up to 75,000 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 ENERZONE SOLUTION 2.5ZC. 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.
Medium Combustion
This is the recommended mode of operating the ENERZONE SOLUTION 2.5ZC 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 ¾ 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 combustion air control. To obtain the
proper combustion, close the combustion air control completely, and then open it about ¼" to
½". Three medium size pieces of wood should be burning on a bed of hot coals. The heat
output will be approximately 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 time will be substantially
reduced.
Slow Combustion
When the air combustion control is completely closed, the fireplace is in a slow combustion
phase. If the heart 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 ENERZONE SOLUTION 2.5ZC with the air control opened to produce a hot
fire for about an hour or at medium pace for at least 2 hours. Slow combustion can be used at
night in order to reduce the heat output and to prolong the burn. The refuelling interval time
will be between 6-8 hours.
