12 - INFORMATION FOR THE SKILLED TECHNICIAN
12.1 MAIN COMPONENTS AND THEIR POSITION
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; the heater is shut down intentionally or the
heater shuts down because it runs out of pellets; the manual reset thermostat trips at 125°C
ROOM FAN
The fan starts automatically as soon as the 42°C th ermostat closes the contact. Likewise it stops when the pellets have run out or
when the heater is shut down, that is when the thermostat opens the contact and in any case not more than 20 minutes later.
SMOKE SUCTION UNIT
This is activated when the start up signal is given. In the first minute it “washes” the smoke discharge tube and functions at
maximum working rate. Once this time has elapsed (1 minute) it self-adjusts to the optimal speed. The exhaust continues to operate
for approximately 20 minutes from the time the heater is switched off to allow for the evacuation of all the smoke and for safety
purposes.
THERMOSTAT AT 42°C
Its function is critical for the following reasons: When the contact closes the heater powers up and the working cycle starts.
Similarly, when the contact opens the smoke exhaust stops.
TANK SAFETY THERMOSTAT
This thermostat starts operating as soon as the temperature in or near the pellet tank approaches 85°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. A red light at the back of the appliance remains lit. Once
the causes for the overtemperature have been identified and remedied the heater can be reactivated by unscrewing the plastic
cover of the thermostat located at the back of the heater and pressing the button (the heater temperature must be below 117 °C ).
GLOW PLUG
It is activated in the switching on phase. It heats the air flowing into the brazier up to 800°C, whic h causes the pellets in the brazier
to ignite and begin the combustion process.
12.2 GUIDELINES FOR CORRECT INSTALLATION
• 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 stove 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.
