k) Once the splinters have caught fire, open the door and add logs, first small ones,
to form the fire. Make sure the logs are far from the glass, so that the glass's
cleaning system works correctly. On the other hand, keep the front door and the
ash pan door closed while the heater is operating.
l) Once the fire is well lit, use the primary air to regulate the level of operating
desired. Moving the control towards the front, to obtain a high level of operating,
and inwardly for a low level of operating.
Note: When you open the door to load the wood or replace the logs in your heater, it
is recommendable to first open only a little, wait a few seconds and then after open it wide.
This procedure will permit the hearth to be free of smoke when you open the heater door
wide and so it does not fill the room. Likewise, to reload on a bed of hot and red embers
reduces the smoke and will intensify the combustion rapidly.
COMBUSTION LEVELS
HIGH COMBUSTION: Fully load the hearth with wood on the hot and red ember bed or
on the flames and entirely open the primary air control. A high level is recommended once or
twice a day to heat the chimney and the heater up well, preventing the creation and
accumulation of creosote.
MEDIUM COMBUSTION: Place the primary air control lever at the middle of the run,
appropriate for the heating needs of the area to be warmed. This level is adequate when the
heater is going to be unattended.
LOW COMBUSTION: Close the primary air control for a slow combustion. A low
combustion level during excessively long periods is not convenient as it stimulates the creosote
accumulation.
The flue system must be often checked if the low combustion level is used on a
continuous basis.
EXCESSIVE FIRE PRECAUTION
Excessive fire means that the heater is running at higher temperatures than those
previously recommended in the section COMBUSTION LEVELS. Excessive fire must be
carefully avoided as it may cause damages to your heater.
The symptoms of excessive fire, even during short periods of time, are roars in the heater
and the connecting duct to the chimney, and decolouring of the chimney tube.
Excessive fire may be caused by an extreme draught in the chimney, inappropriate fuel
or incorrect operating.
Correct an excessive fire situation in the following way:
o EXCESSIVE DRAUGHT: The draught depression must not be more than 2.5 mm
c.a. A draught that exceeds this value requires a draught cutting valve in the
chimney.
o INAPPROPRIATE FUEL: Do not burn coal, heaps of dried splinters, waxed logs or
any others than the natural wood recommended.
o OPERATING ERROR: Make sure all the joints are in good state. Replace the
frayed or crushed joints. Do not light the heater with the front, side or ash pan
doors open.
Controlling the temperature is the best way to determine if the heater has excessive fire.
If you suspect your heater has excessive fire, contact your supplier immediately. The damages
caused by excessive fire are not covered by the warrantee. The results of an excessive fire may
include deformations or burning of internal parts, decolouration and deformation of external
parts and damages on the enamel.
NOTE: ANY SYMPTOM OF EXCESSIVE FIRE MAY ANNUL YOUR WARRANTEE!!
