PRECAUTION WITH EXCESSIVE FIRES
Excessive fires means that the fire is working at temperatures above those
recommended previously in the COMBUSTION RANGE section. Excessive fires must be
carefully avoided as they can cause damage to your stove.
The symptoms of an excessive fire, even for a short time, are creaking in the stove and
the connection conduct of the chimney, and discolouring in the chimney pipe.
Excessive fires may be caused by an extreme draught on the chimney, inappropriate
combustion or erroneous operation.
Correct a situation of excessive fire as follows:
o EXCESSIVE DRAUGHT: The depression of the draught must not exceed 2.5
mm.c.a. A draught that exceeds this value requires a draught valve in the
chimney.
o INAPPROPRIATE FUEL: Do not burn coal, stacks of dry twigs, waxed logs or any
material other than the natural wood recommended.
o ERROR IN OPERATION: Make sure that all the joints are in a good state.
Replace all loose or compressed joints. Do not light the stove with the front, side
or ash tray door open.
Controlling the temperature is the best way to determine whether the stove has
excessive fire. If you suspect that your stove has excessive fire, contact your supplier
immediately. The damage caused by excessive fire is not covered by the guarantee. The results
of excessive fire may include: deformations or burns in the internal pieces, discolouring and
deformations in external pieces and damage to the enamel.
NOTE: ANY SYMPTOM OF EXCESSIVE FIRE MAY ANNUL THE GUARANTEE!!
The temperature of the stove may be controlled with a special thermometer for stoves
located in the centre of the top.

2.2.1 - PREVENTING AND CLEANING THE CREOSOTE.

To prevent the formation of creosote:
1. Keep the stove with the primary air open completely for 30 minutes each day to burn
the creosote inside the stove and the evacuation system.
2. After reloading with firewood, keep the combustion with the primary air control fully
open for 20 or 30 minutes. This form of operation ensures the operation of the secondary
combustion, which, when it works, minimises the formation of creosote in the chimney.
The connector pipe of the chimney must be inspected at least once a month during the
season when the stove is used, to determine whether creosote has formed. If the creosote
residue has an accumulated layer of 6 mm. it must be eliminated to reduce the risk of fire.
If the glass gets dirty frequently, the temperature range of the combustion is low; this
indicates the risk of the formation of creosote.
The smoke evacuation system must be inspected in its connection with the stove and at
the top of the chimney. Cold surfaces tend to create deposits very quickly and so it is important
to inspect the chimney at the top end as this is the coldest area, unlike the stove connection.
The accumulated creosote must be eliminated with a cleaning brush designed
specifically for this use.
