MAIN CHECKS TO BE PERFORMED
•
The pellets have run out, refill the hopper.
•
The gear motor is not running, check the reason:
-
Not connected to the mains.
-
Mechanically disconnected from the auger.
-
Gear motor broken.
•
The auger is blocked by a foreign body which has fallen into the hopper.
•
The auger is blocked by very hard pellets; use the recommended pellet types (see CHAP.06.2 -
RECOMMENDED FUELS).
•
The basket is dirty. Clean carefully and reposition it correctly.
•
The basket is positioned incorrectly, replace it.
•
The resistance is faulty, replace it.
•
Stove started with correct pellet pre-load.
•
The amount of pellets loaded in the basket for the various output modes does not correspond to the amounts
indicated in the Technical Specifications (see CHAP.06 - TECHNICAL DATA), check and correct the
parameters.
•
Low flue draught, do not use the fireplace, it could be dangerous; carefully clean the flue, the appliance and
the fume extractor.
•
Firebox is very dirty. Switch off the appliance and clean it.
•
Humid pellets. Replace the fuel.
•
The comburent air is scarce; make sure that the pellet drawer is well closed, that it is not full of ash.
•
Insufficient comburent air settings, change the comburent air flow value.
•
Check air inlet in the burner.
•
The combustion fan speed is very high and the pellets are burning too quickly.
•
The pellet supply is running out.
•
The flue draught rate is too high.
•
The pellet load is too high, it does not all burn within the set time and fresh pellets accumulate inside the
Adjust the load level, or correct the combustion fan speed.
firebox.
•
Pellet size is very small, adjust loading time
•
Check the bottom of the pellet container; there may be large deposits of sawdust.
•
The gear motor may have broken gearings, running empty.
•
The pump start temperature limit is too low. Raise temperature to minimum 65°C.
•
The anti-condensation valve may require replacement.
•
The electronic circuit board is broken. Replace it.
•
At first start up or after prolonged disuse, condensation may form on resistances. Repeat start up until the
resistance expels all humidity.
•
Air in the system: Vent all radiators, pump and boiler.
•
Check whether any intercepts (zone vales) are closed.
