WARNINGS
• NEVER OVERFIRE YOUR STOVE. IF ANY PART OF THE STOVE STARTS TO GLOW RED, OVER FIRING IS
HAPPENING. READJUST THE AIR INTAKE CONTROL AT A LOWER SETTING.
• THE INSTALLATION OF A LOG CRADLE or GRATES IS NOT RECOMMENDED IN YOUR WOOD STOVE. BUILD FIRE
DIRECTLY ON FIREBRICK.
• NEVER PUT WOOD ABOVE THE FIREBRICK LINING OF THE FIREBOX.
• Attempts to achieve heat output rates that exceed heater design specications can result in permanent
damage to the heater.
EFFICIENCIES
Efciencies can be based on either the lower heating value (LHV) or the higher heating value (HHV) of the fuel.
The lower heating value is when water leaves the combustion process as a vapor, in the case of woodstoves the
moisture in the wood being burned leaves the stove as a vapor. The higher heating value is when water leaves
the combustion process completely condensed. In the case of woodstoves this would assume the exhaust gases
are room temperature when leaving the system, and therefore calculations using this heating value consider
the heat going up the chimney as lost energy. Therefore, efciency calculated using the lower heating value of
wood will be higher than efciency calculated using the higher heating value. In the United States all woodstove
efciencies should be calculated using the higher heating value.
The amount of visible smoke being produced can be an effective method of determining how efciently the
combustion process is taking place at the given settings. Visible smoke consist of unburned fuel and moisture
leaving your stove. Learn to adjust the air settings of your specic unit to produce the smallest amount of visible
smoke. Wood that has not been seasoned properly and has a high wood moisture content will produce excess
visible smoke and burn poorly.

RELOADING
Once you have obtained a good bed of embers, you should reload the unit. In order to do so, open the air
controls to maximum a few seconds prior to opening the stove’s door. Then proceed by opening the door very
slowly; open it one or two inches for 5 to 10 seconds, before opening it completely to increase the draft and thus
eliminate the smoke which is stagnant in a state of slow combustion in the stove. Then bring the red embers to
the front of the stove and reload the unit.
For optimal operation of your wood stove, we recommend you to operate it with a wood load approximately
equivalent to the height of re bricks.
It is important to note that wood combustion consumes ambient oxygen in the room .In the case of negative
pressure, it is a good idea to allow fresh air in the room, either by opening a window slightly or by installing a fresh
air intake system on an outside wall.
Creosote - Formation and Need for Removal - When wood is burned slowly, it produces tar and other organic
vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively
cool chimney ue of a slow-burning re. As a result, creosote residue accumulates on the ue lining. When ignited
this creosote makes an extremely hot re. The chimney connector and chimney should be inspected at least
once every two months during the heating season to determine if a creosote build-up has occurred. If creosote
has accumulated (3mm or more), it should be removed to reduce the risk of a chimney re.
We strongly recommend that you install a magnetic thermometer on your smoke exhaust pipe, approximately
18” above the stove. This thermometer will indicate the temperature of your gas exhaust fumes within the smoke
exhaust system. The ideal temperature for these gases is somewhere between 275°F and 500°F. Below these
temperatures, the build-up of creosote is promoted. Above 500 degrees, heat is wasted since a too large quantity
is lost into the atmosphere.
