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 glass door is closed.
• The ash collection box is inserted into its holder.
• 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 powered; if there is power and it does not turn,
replace it with a new one (if for any reason the fan does not work, the stove will stop
automatically, triggering the resetting safety thermostat, due
to overheating).
• The resistance is red-hot.
If it is not working, make sure that it is powered; 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 re-
moving the fuel from the fuel box).
• The vacuum pressure switch has not been blocked by poor
combustion or an obstruction in the exhaust pipe (re-activate
it by blowing and sucking until you hear the switch come in-
to operation).

• The flue gas outlet pipe is inserted properly into the exhaust outlet; if not, an electrical
device will block operation of the stove by switching it off.
• Check whether the stove is ready for programmed cleaning after 1100 hours have ex-
pired.The display will show the letter P permanently.
• If the problem persists, consult your retailer.
2. If the stove goes out during operation:
• Check all the possibilities in previous section.
• Check whether the stove is ready for programmed cleaning after 1100 hours have ex-
pired.The display will show the letter P permanently.
• Make sure that the thermal safety switch (re-settable manually), on the inside back right
of the stove, has been reset.
• Before resetting the switch find the reason for its triggering. Note that the thermal
switch can only be reset with electrical supply off and when the stove temperature has
fallen below 93°C.

POWER FAILURE

Brief power failure: if there is a brief power failure (60 seconds), when the stove is at the
ignition stage or is operating normally, the stove is programmed to re-ignite itself. If the
power failure lasts for a longer, indefinite period, when the power returns the stove will go
into an extinguishing cycle, setting up for the next (manual or programmed) ignition. In this
case the display will indicate the failure by three yellow LED's lighting up alternately.
To reset the stove functions, switch it ON-OFF.
Temporary power failure: If there is a power failure lasting 3 / 5 minutes, with direct
flue gas exhaust pipes the stove may emit some smoke into the room, produced by the un-
burnt pellets present in the grate.
This does not constitute a safety risk.The problem can be avoided by installing the exhaust
pipe as shown on this handbook.
Electrical safety: the stove is protected against power surges by two fuses on the elec-
tronics board.
