Function
Start with the boiler cold.
Set the main switch, 2
0, to the ON-position – the green area must be
visible.
Set the thermostat, “FAN STOP”, 21, to 120° (250°F). The thermostat
detects the flue gas temperature.
Press “FAN START”, 22, the time relay, 24, is activated and the fan
starts.
When the time set for the time relay, 30 minutes, is reache
d, the
contact changes, which means that the fan and the charging pump
for the accumulator system are controlled by the thermostat, 21.
When the firewood is burnt out and the flue gas temperature falls
below the value set for the thermostat, 21, the fan and charging pump
stop running.
If the boiler temperature exceeds 220°F, the overheating protection is
triggered. The fan stops running and the charging pump continues to
operate.
If the overheating protection, 25, is triggered, the “ALARM” indicator,
26, is lit. The relay, 23, prevents the time relay activating when the
overheating protection is triggered.
To reset the overheating protection, press “RESET”, 25, on the boiler
control panel. Note that it is not possible to reset the system until the
boiler temperature has dropped below 200°F.

Electrical.connection
The boiler is connected directly to the mains.
The electrical connections are at the rear of the boiler, in the form of
three quick connectors:
15. Mains connection, 115 V~, cable with quick connectors supplied.
16. Fan.
17. Circulation pump, for charging the accumulator system.
Always disconnect the power supply to the
boiler before accessing the automation
cabinet or units powered by the boiler.
