correct afflux of the air.
●
The lack of draught by the flue (or, for instance, the obstruction or closing of the air entrance of
the grate, or of the grate itself) alters the functioning of the boiler, which, while automatically
switching-on, may provoke an excessive pellet dosage in the grate, due to delayed fire priming.
Excessive smoke in the combustion chamber can cause an automatic priming of the fumes
(gas), accompanied by a violent flame; in these conditions, we recommend never opening the
combustion chamber door.
●
Categorically avoid using inflammable liquids to start the fire; when the boiler is on, the pellet
lighting is automatic.
●
The pellets feeding the boiler must necessarily present the characteristics described in this
handbook.
●
Do not touch the glass when the boiler reaches its temperature; be cautious before touching the
boiler.
●
Avoid letting children close to the boiler on their own, when it is on, because each hot surface
can provoke severe burns.
●
Do not perform interventions on the boiler, apart from those expected for a regular functioning
or suggested in this handbook in order to solve slight problems. In any case,
always unplug
the boiler from the power supply before an intervention, and operate solely when the
boiler is cold.
●
It is absolutely forbidden to remove the guard protecting the pellet tank.
●
In case an intervention to the waterworks is necessary, make sure that the boiler is off, that the
water afflux to the boiler is stopped and that the water already in the boiler is completely cooled.
●
Always make sure and check for the combustion chamber door to be hermetically closed when
the boiler is lighting or functioning.
●
The pellet automatic lighting is the most delicate phase; in order for it to take place without
inconveniences, we recommend always to keep the boiler and the grate clean.

If anomalies in the functioning should occur, light the boiler again only after fixing the problem
at its origin.

Karmek Srl is not responsible for inconveniences, tampering, breakages or any other damage
due to non-observance of the instructions reported in this handbook.
