WARNING!
Do not use the fireplace if the draught is not regular and combustion is not optimum!
PROBLEM CAUSE AND/OR CURE
The electronic controller does not
switch on
• Check for possible power supply or mains problems.
• Check that the green connector of the display is correctly connected at the rear.
• The electronic controller is faulty.
No pellets enter the burn pot
• The electronic controller is in wood mode. Select pellet mode.
• The pellets are finished, refill the hopper.
• Damp pellet blocked into the gear motor
The in feed screw does not rotate
• The in feed screw is blocked by pellets that are too hard (only use pellets of the recommended type); free
the in feed screw by turning the pin protruding from the burner casing.
• The gear motor is not powered (check and eliminate the causes).
• Motor relay CLOCKED IN OPENING =BROKEN : replace it on the mother card.
• The gear motor does not turn even though powered (remove the gear motor, free the in feed screw with
a screwdriver and refit the gear motor).
• The motor turns but the in feed screw does not move. Replace the gear motor (broken gears).
The stove does not light
automatically in pellet mode • Summer mode is set.
• The burn pot is dirty. Clean it thoroughly and refit correctly.
• The burn pot is not correctly positioned. Reposition and clamp it, tightening the locking screw with the
special wrench supplied
• The electrical element is faulty; replace the electrical element. In the meantime, light the stove manually
using firelighters (or similar products).
The pellets burn poorly forming
incompletely combusted residue
in the burn pot, the glass gets very
dirty and turns black
• The quantity of pellets fed into the burn pot at the various power levels does not comply with that given
in the Technical Data (see
chap. 1.3
). Check and correct.
• Insufficient flue draught (do not use the stove, it could be dangerous). Clean the flue and the stove
thoroughly.
• Pellet burn pot dirty. Clean it. Burning pot in a wrong position (see
chap 1.13
page
26
)
• Pellets damp. Replace with dry pellets.
• Insufficient combustion air; check that the combustion fan pipe is unobstructed and clean the fan.
• Insufficient combustion air setting. Increase the setting in the SET COMB. AIR function in the Quick
Menu.
At minimum power, the fireplace
always goes off because not
enough pellets are fed • Too much sawdust on the bottom of the hopper. Empty the hopper and refill with new pellets. (every
500-1000 kg of pellets loaded, empty the hopper and remove all the sawdust deposited on the bottom).
• Increase the pellet feed in the SET PELLET % function in the Quick Menu.
At minimum power, the fireplace
always goes off because too many
pellets are fed and do not burn
• Reduce the pellet flow rate in the SET PELLET % function in the Quick Menu.
• Increase the combustion air.
When the hot air fan starts, the
flame is considerably reduced • Make sure the outside air inlet complies with the indications given, and that it is clean.
• Make sure the fan ducting complies with the indications given, and that it is clean.
When the hot air fan speed
increases, there is smell of smoke
in the room
• Check the seal of the fire bed plate under the ash pan.
• Make sure the flue is properly connected to the fireplace and that there are no smoke leaks.
• Make sure the outside air inlet complies with the indications given, and that it is clean.
• Make sure the fan ducting complies with the indications given, and that it is clean.
Smoke escapes when the door is
opened, the pellets burn poorly,
or the glass gets dirty (particularly
when used with wood) • If the fireplace is installed in a room in communication with a stairwell, with major depression that exists
in the local, close off the stairwell by installing a door.
• There are other appliances that use room air, creating low pressure. Use the fireplace when the other
appliances are off (excluded of the type “C” according to UNI 10683).
• The outside air inlets and/or the flue are partially or completely obstructed. Clean or remove the
obstructions. Air inlet and/or canalisations not correctly done.
• Clean the Smoke Deflector (see chap.1.10 )
• Insufficient flue draught: there are horizontal sections or 90° bends, or the chimney cap is located
under the ridge of the roof (installation errors). Remove the precut part from the smoke baffle
(see
chap. 1.8 ); replace the horizontal sections with sections at 45°; raise the chimney cap, or fit an
antiwind cap.
• Check that the flue conforms to the indications given in chap. 2.1 , clean the flue and smoke baffle, open
the damper, open the door slowly. If after these operations smoke still comes out, eliminate the precut
part of the smoke baffle (see
chap. 1.8 ).
