Technical instructions Cm Pelet-set
burner so pellets can drop freely into the burner;
the burner grate is located correctly in the burner
(that it does not rest ON electric heater);
pellets are not too moist;
pellets are of appropriate size (for these burner
setting they should have diameter of 6 mm);
hot air blows from the burner (i.e. whether electric
heater has not blown);
the photocell sensor is clean.
Possible fan stoppage.
Possible filling up of the burner combustion chamber
and feeding tube due to wrong set of combustion air
wrong set parameters of charge,
inadequate size or quality of pellets, incorrectly set
air in combustion chamber.
Inappropriate pellet size and quality.
Possible hole in flexible tube or disconnection of
flexible tube from feeding tube.
possible delays fan.
Check sensor position.
Check damages of sensor and cables.
Check contacts on connectors.
Check sensor position.
Check damages of sensor and cables.
Check contacts on connectors.
Due to lack of pellets, feeding of too moist pellets, or
due to dirty photocell.
Resetting of control unit to factory setting is required.
Due to failure of rpm sensor, due to failure of fan
bearings (check whether it can rotate freely), due to
entrance of foreign object into the fan rotor, due to
activation of fan overheating protection (after cooling
down by 30°C fan can be restarted).
Check the burner grate fill, burner combustion
chamber, combustion chamber of the boiler, flue gas
tube and chimney, is the burner grate is properly
placed in the burner (that is not set to the electric
heater), whether the pellets are moist, not properly
size or quality of pellets (for these burner settings is
properly diameter of 6 mm), possible holes in a
flexible tube, incorrectly configured parameters of
charge, incorrectly adjusted air combustion.
Check filling up level of the burner grate, burner
combustion chamber and check possible methods to
eliminate errors E2 and E6.
