Clean the FIRE CHAMBER HEAT EXCHANGER thoroughly at regular
intervals by removing the cast-iron rear wall once it is cold.
Grip the inside handles, lifting and rotating the plate outwards.
Scrape the sides and the internal pipes of the heat exchanger.
Lastly, make sure that the smoke holes (A) (Fig. 31) are not clogged
with ashes.
WARNING:
Check that the door is airtight at regular intervals (no air must be
allowed to get in between the door stop gasket and the burn pot’s lower
gasket).
If the stove is not cleaned properly or often enough, operating pro-
blems may be encountered such as:
· combustion is poor
· window goes black
· burn pot clogs with ashes and pellets
· ashes and excessive deposits on exchanger, resulting in reduced
efficiency.

CLEANING THE GLASS
Dab a damp cloth or ball of newspaper in ashes. Wipe the glass until it
is completely clean. Detergents for cleaning kitchen ovens can also be
used. Do not clean the glass whilst the stove is operating, and do not
use abrasive sponges.

CLEANING THE FLUE (Fig. 32)
Clean the flue at least twice a year, at the start of the winter and half way
through, or whenever it proves necessary.
If there are horizontal sections, check for any ash deposits or soot and
remove them before they stop the smoke getting through.

4.1 DESCRIPTION OF THE STOVE’S INTERNAL COMPONENTS
Work on internal components must be carried out by qualified person-
nel only, i.e. people working in the technical sector such as burner
experts or electricians who are familiar with the workings of electrical
and combustion systems.
WARNING: Always unplug the stove before removing panels to reach
internal components.
4.1.1 REACHING INTERNAL PARTS
In order to get at the internal components, remove the box’s side
panels. The rear side panels (the wider ones) are removed by un-
screwing the screws from inside the pellet bin, whilst the two front side
panels (the narrower ones) (Classic version) are inserted by means of
a bayonet coupling and are removed by simply prising them open with
a screwdriver inserted under the top of the panel.
4.1.2 AUGER MOTOR (L) (Fig. 35)
The intensity of the fire can be varied by adjusting the operating cycles
of the auger which, in turn, alters the feeding of pellets:
MAX.
1.6 seconds in OPERATION 0.1 - 0.5 second PAUSE
MIN.
1.6 seconds in OPERATION 6 - 4 second PAUSE
Regulate using the knob on the left (A)(Fig. 33).
Should the feed auger jam, rotate the motor (L) manually anticlockwise
to release it. Make sure that the auger and motor shaft are firmly
locked together.
4.1.3 DRAUGHT FAN (B) (Fig. 34)
This fan is connected in parallel to the feed auger and regulates the
rate at which smoke is expelled depending on the intensity of the fire,
i.e. the setting of knob (A). It also sucks combustion air into the fire
chamber.
4.1.4 HOT-AIR BLOWER (C) (Fig. 34)
This fan is turned on when the stove’s box is hot by a normally open
thermostat (circuit closes at 46° C). The speed of rotation can be
regulated by means of the blower knob on the right (Y) (Fig. 33) from
MIN to MAX.
Clean the blower at regular intervals with a vacuum cleaner, first remo-
ving the lower grille on the front.
4.1.5 BLOWER THERMOSTATS
The first normally open thermostat (set to 46° C) (G) (Fig. 34) starts the
fan when the temperature of the fire chamber exceeds 46° C (even
during the Startup phase) and turns it off when the temperature falls
below 46° C.
A second normally open thermostat (set to 110° C) (H) (Fig. 34) auto-
matically starts the fan at maximum speed when temperatures in the
box are extremely high, before returning to the chosen setting.
4.1.6 NORMALLY OPEN MINIMUM SMOKE TEMPERATURE
THERMOSTAT (F) (Fig. 34) - Set to 46° C
The purpose of this thermostat is to enable the stove to make the
transition from “Startup” phase to “Operating” phase and to cut off the
stove’s power supply when the temperature of the fire chamber falls
below 46° C.
4.1.7 PRESSURE SWITCH (D) (Fig. 34)
The DUNGS-type pressure switch model LGWA1 (D)(Fig. 34) is set to
approx. 5 mm in a normally open vertical position. It controls the vacu-
um created in the fan suction circuit, and closes the electric circuit
supplying power to the gearmotor of the feed auger. If the flue is
closed, the exchanger clogged or the draught fan broken, the pressu-
re switch stops the feed auger (trips for safety).
4.1.8 SAFETY THERMOSTAT WITH MANUAL RESET
A normally closed thermostat set to 145° C (I)(Fig. 34) opens its electric
contacts and stops the pellet feed auger when the fire chamber ove-
rheats.
When this happens, the cause of overheating must be determined (the
blower is not working, overloading of pellets, etc.) and the problem
solved.
Before the stove can resume operation, the thermostat must be reset
by pushing the relevant red reset button.
4.1.9 ROOM TEMPERATURE THERMOSTAT
Knob (X) (Fig. 33) is used to set the desired max. room temperature.
Once the selected room temperature has been reached (detected by
sensor (K)), the stove automatically switches to minimum operation
(pellet loading setting 2) until power is called for again.
4.1.10 DRAUGHT FAN CAPACITOR
The capacitor (M) can be found on the right-hand side (Fig. 35).
4.1.11 ELECTRIC CIRCUIT BOARD
The board can be found on the right-hand side (O) (Fig.36), and is
protected by a metal cover.
Remove the cover to reach the circuit board and relevant terminal
board and coupling. There is a 2 amp safety fuse by the green termi-
nal board on the right, and it can be reached by removing the fuse
carrier cover.
4.1.12 LIGHTING RESISTOR (Fig. 37)
Combustion is achieved automatically thanks to a resistor. The resistor
is inserted in a duct located under the burn pot and is designed to
overheat part of the air brought in by the draught fan and introduce it
into the burn pot to light the pellets waiting there.
Startup phase:
The resistor comes on as soon as the stove is switched on (switch set to
P) and stays on for about 7 minutes before going off automatically. The
first flame can be seen about 4-6 minutes after switch-on.
Replacement:
If the resistor needs to be changed (it can also be classed as a consu-
mable), simply pull the resistor out from the front of the tube housing it:
remove the lower grille and slide the part to the left once the fastening
screw is unscrewed.
Warning: check the system’s holes are properly aligned (see Fig. 37)
Resistor rating: 350W – 230 V
