• Carry out general cleaning of all parts in between the two doors, and reassemble all parts
in an inverse sequence.
The advice about regular cleaning and maintenance is only indicative and may vary accord-
ing to the quality of the pellets used in the stove, therefore whenever you note worsening
combustion or increased dirt on the fireplace and glass surface this cleaning should be car-
ried out in any case.
We recommend taking out an annual maintenance contract with the place where you
bought the stove. In this way you will be able to programme cleaning of the stove at the end
of the season, keep it in working order and ensure it is ready to operate properly the fol-
lowing season.
WARNING
Installation and extraordinary maintenance must be done only by skilled, technical personnel.
• IMPORTANT NOTE: if the stove is connected to the outside by a metal flue gas ex-
haust pipe, two conditions could be deleterious to good combustion.
1- If the horizontal part of the flue gas exhaust pipe is too long, this will worsen the quali-
ty of combustion and noticeably increase ash residues in the grate. For this reason the
electronics board has a facility for regulating both the exhaust pressure and pellet load-
ing rate.This should be carried out only by the installer technician, at installation or when
conditions make it necessary.
2- A vertical metal exhaust pipe that is three / four metres long will increase the combus-
tion rate.This will cause the stove to go out at the minimum power level.To prevent this
just increase the selected power level or change the original settings.
If these adjustments prove insufficient, the stove is supplied with a diaphragm valve.This
device is installed externally to the air combustion tube and allows manual adjustment of
the air reaching the combustion hearth.
MAINTENANCE OF THE SMOKE EXHAUST DUCT
• Annually, we recommend cleaning the smoke exhaust duct in order to prevent self-com-
bustion of any soot and powder that may be deposited there.
• In case of fire switch off the stove immediately and disconnect it from the power supply.

OPERATING PROBLEMS AND SOLUTIONS

Warning! Only skilled technical personnel are allowed to dismantle the stove and
work on the internal components.
Before carrying out any operation whatsoever, disconnect the power supply and wait
until the stove has completely cooled down.
1. If the stove does not ignite, make sure that:
• It is connected to the electricity supply.
• The combustion heart is inserted into its holder.
• The glass door is closed.
• Pellets arrive in the grate; make sure the pellet box contains sufficient fuel for the stove
to operate. If the pellet supply finishes during use, the stove will switch off by itself.
• The thermal safety switch has been reset; otherwise disconnect the power supply, reset
the switch by pressing the button on the switch itself, then restore the power supply.
• The combustion air pipe is completely open.
• The exhaust gas flue is completely open and the gas is free to leave. If not this would fail
to generate the necessary negative pressure and the vacuum pressure switch would in-
terrupt the power supply to the pellet loading motor.
• The flue exhauster motor works properly. If it is not working, make sure that it is pow-
ered; if there is power and it turns slowly, replace it with a new one (if the flue exhauster
motor stops, the electronic board will immediately block the supply of pellets).
• The screw motor is working properly.
If it is not working, make sure that it is powered; if there is power and it does not turn,
replace it with a new one (if the motor reducer stops, the stove will use up the fuel in
the grate and then go out completely).
• The hot air fan is working properly.
If it is not working, make sure that it is pow-
ered; if there is power and it does not turn, re-
place it with a new one (if for any reason the fan
does not work, the stove will stop automatical-
ly, triggering the resetting safety thermostat, due
to overheating).
• The resistance is red-hot.
If it is not working, make sure that it is pow-
ered; if there is power and it does not heat up,
replace it with a new one.
• The worm is not obstructed by a foreign body
(check by removing the fuel from the fuel box).
