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.
-Pellets finished.
-The manual reset thermostat trips at 125°C
ROOM FAN
The fan starts automatically as soon as the 42°C thermostat closes the contact. The fan stops when the fuel tank is empty or when the heater
is switched off intentionally, two situations in which the thermostat's contact is opened.
SMOKE SUCTION UNIT
This is activated when the start up signal is given.In the first two minutes 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 one hour from
the time the heater is switched off to allow for the evacuation of all the smoke and for safety purposes. It stops 30' after the thermostat at 42°C
opens.
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 start 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 START phase.Heats the air to 800°C, which assist the first combustion of the pellets present in the brazier.
12.2 USEFUL ADVICE FOR INSTALLATION AND OPERATION
1
The appliance must never be deliberately disconnected from the electric power supply. Whenever the appliance is deliberately
disconnected from the electric power supply smoke could be emitted into the room and be a hazard.Similarly never switch off the heater by
suddenly cutting off the electric power supply.
2
Do not install the appliance with horizontal wall outlets only:evacuation of the combustion products must be guaranteed in a natural
manner.
3
Do not install the appliance with horizontal sections only: the wall could be exposed to high wind conditions and the heater could shut
down due to back draft.
4
Operate the appliance at maximum for 10 hours for a complete drying and baking of the silicates contained in the enamel which covers
the body of the heater.
5
Do not install a grill or outlet terminal which could restrain the flow of the combustion gases:this could affect the dynamic gas to the point
where it would not allow the pellets to burn correctly.
6
Read this instruction booklet.
7
Keep the appliance clean and check the burner as described in this manual.
8
Clean the smoke outlet regularly.
9
Use top quality pellets: by saving 20 cents a bag you heat up to 50% less.
10
Maximum useable lengths of smoke exhaust tubes:
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
Maximum vertical length
Length with min slope .5%
Maximum number of elbows at least 0.5 m apart
