12 - INFORMATION FOR THE SKILLED TECHNICIAN
12.1 MAIN COMPONENTS AND THEIR OPERATION
SMOKE PRESSURE SWITCH
This is a safety switch that stops the screw feeder motor whenever necessary. The main cause for the pressure switch tripping is a
blocked flue outlet or smoke exhaust pipe. Note that it is strictly forbidden to apply any kind of mesh screen to the end of the pipe.
When the holes of the mesh clog up they create a plug that trips the pressure switch which stops the pellet feeder.
SCREW FEEDER MOTOR
This motor is powered at regular on/off intervals controlled by a microprocessor. The operation of this motor is affected when:
-The motor's thermal cutout trips. -The pressure switch trips due to blocked smoke exhaust.
-Pellets finished. -Voluntary shut down of the appliance. -The manual reset thermostat trips at 125°C
ROOM FAN
Starts automatically as soon as the smoke thermocouple detects a suitable smoke temperature. Similarly it stops when the fuel is
finished or during a voluntary shut down when the smoke thermocouple detects a suitable temperature for activating (to a maximum
of 20 minutes).
SMOKE SUCTION UNIT
This is activated when the appliance starts up. In the first minute it «washes» the smoke discharge tube, that is, it functions at
maximum working rate. Once this time has elapsed it self-adjusts to the optimal speed. The exhaust continues to operate for
approximately twenty minutes from the time the appliance is switched off to allow for the evacuation of all the smoke and for safety
purposes.
THERMOCOUPLE
Its function is to verify the temperature of the combustion smoke: when the smoke temperature exceeds a certain value it indicates
that the appliance is on. Similarly, when the temperature drops below a certain limit it causes the presence of AL PE on the display.
TANK SAFETY THERMOSTAT
This thermostat starts operating as soon as the temperature in or near the pellet tank approaches 95°C and sends an immediate
signal to the room fan to operate at maximum power.
125°C MANUAL RESET THERMOSTAT
When the temperature exceeds 125°C the pellet feed screw shuts down. Display shows the inscription “AL T max”. Once the
causes for the overtemperature have been identified and remedied the appliance can be reactivated by unscrewing the plastic
cover of the thermostat located at the right side of the appliance and pressing the button (the appliance temperature must have
considerably dropped).
GLOW PLUG
It is activated in the START phase. Heats the air to 800°C, which assist the first combustion of the pel lets present in the brazier.
The spark plug is guaranteed for a period of 6 months.
12.2 REQUIREMENTS NECESSARY FOR CORRECT INSTALLATION AND OPERATION
• Read this instruction booklet.
• The appliance must always be switched off from the control panel. It is forbidden to switch off the appliance by means of the
switch installed on the back of the heater.
• The appliance must never be disconnected from the electrical power supply and the power supply must never be cut off during
normal operation. Whenever the appliance is deliberately disconnected from the electric power supply smoke could be emitted into
the room.
• Do not install the appliance with horizontal wall outlets only: Evacuation of products of combustion by natural draught must always
be guaranteed as well. Unsuitable installation of the outlets could cause a forced shut down of the appliance due to overpressure of
the exhaust smoke caused by a gust of wind.
• At the first startup, run the heater at the maximum power and minimum ventilation for at least ten hours in a well-ventilated room,
in order to dispose of the smoke generated by the complete dryness and baking of the silicates contained in the enamel coating of
the combustion chamber.
• Do not install a grill or outlet terminal that could slow down the flow of the combustion gases: this would obviously cause the
appliance to malfunction.
• Keep the appliance clean and check the burner as described in these instructions.
• Clean the smoke outlet regularly.
• Use good quality pellets: use of poor pellets can result in up to 50% less efficiency.
• The pellets must be stored in a well-ventilated, dry place.
• Sizing of the chimney liner:
Painted aluminized steel tubes (1.5 mm minimum thickness), Aisi 316 stainless steel tubes or 0.5 mm enamelled tubes may be
used. Minimum vertical length 4 m / Maximum vertical length 8 m / Length with minimum slope 5% 0.5 m
Maximum number of elbows at least 0.5 m apart: 2
• The appliance door must always remain closed during normal operation.
• Do not touch hot outer surfaces, unless with special equipment.
• Do not pour the pellets directly into the brazier.
• Keep fuel and inflammable materials at a suitable distance.
• Use only original spare parts supplied by the manufacturer.
