THERMOSTAT AT 42°C
Its function is critical for the following reasons: When the contact closes the heater / boiler powers up and the working cycle starts. Similarly,
when the contact opens the smoke exhaust stops.
EXPANSION TANK 2,5 l
This is a safety device intended to compensate for the increased volume of the water in the boiler caused by the increase in the water
temperature ( Note: this tank is a protection for the boiler only).
SAFETY THERMOSTAT WITH MANUAL RESET
When the temperature exceeds 98°C the pellet feed screw shut s down. A red light at the back of the appliance remains lit. 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 back of the appliance and pressing the button (the heater / boiler temperature must be below 73 °C).
GLOW PLUG
It is activated in the START phase. Heats the air to 800°C, which assist the first combustion of the pellet s present in the brazier.
BOILER PRESSURE GAUGE 0-4 bar
Detects the water pressure in the system. It is installed at the back of the heater/boiler.
AUTOMATIC PURGE VALVE
The function of this valve is to eliminate air residues inside the heater/boiler without the need for manual intervention. Consequently problems
such as the following are eliminated:
-corrosive processes caused by the oxygen.
- noise generated by the passage of air in the tubes.
-air pockets in the heating bodies.
- cavitation in the circulator pumps .
SAFETY VALVE CALIBRATED AT 3 BAR
When the calibrated pressure is reached, the valve opens and, by discharging to the atmosphere (the manufacturer recommends connecting this
valve to a single outlet to avoid damaging the material surrounding the heater / boiler if it is activated ) it prevents the pressure in the system from
reaching dangerous limits for the generator and for the components of the system . If it trips verify the reasons and solve the causes for the
overpressure.
SYSTEM CIRCULATOR PUMP
This device conveys hot water produced by the appliance to the usage point. The pump signal appears to indicate that it is operating.
11.2 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 appliance 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 appliance 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
4 m
Maximum vertical length
8 m
Length with min slope .5%
0.5 m
Maximum number of elbows at least 0.5 m apart
