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, 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.
3.2.8 Smoking − Causes and Troubleshooting
To reduce the likelihood of smoking when opening the door, set the combustion air controls
to the right (accelerated) before opening the door. Your fireplace has been designed and tested
to provide smoke free operation. Occasionally, there may be a small amount of smoking upon
lighting the fire, until the chimney heats up but this should not continue. If the fireplace
continues to smoke it is probably for one of the following reasons:
A. Negative pressure in the house
As the fire burns, air goes up the chimney. This air must be replaced through leakage into
the house or through the fresh air kit. When operating the ENERZONE SOLUTION
2.5ZC, open a nearby window temporarily to check if there is adequate air supply
replacement. If opening a window solves the problem, the house is under negative
pressure.
B. Fans operating (e.g. : range hood)
These fans draw air out of the house and may actually cause a negative pressure in the
house. Turn off all fans and open a nearby window to determine if this is the cause of the
problem.
