MOUNTING THE BURNER
To proceed with the installation of the oil burner, respect and follow the instructions contained in the specifically manual
of the burner in detail.
ELECTRICAL CONNECTION
The equipment is supplied with the electrical panel mounted as standard and with the motor/s and the FAN-LIMIT
thermostat/s connected. The connections to be carried out are therefore the following:
The mains electrical connection;
The connections to the burner;
The connections to the room thermostat;
Any other accessories (fire barrier lock, humidifier, etc.).
For all connections use the cable grips in the electrical and the terminal block in the panel itself, in accordance with the
specific wiring diagram for each equipment model.
WARNING!
Install a magnetothermal switch before the equipment of suitable size based on the technical details indicated in the
paragraph “Technical and performance features” and in accordance with the law in force.
Have authorised personnel to check out the cable diameters and maximum electrical plant power absorption by the
equipment as indicated on the plate;
Always earth the equipment. Leave the earth cable a little longer than the line wires so that, if they are accidentally
pulled, it is the last to get detached;
Respect the polarities when making the electrical connections.
In order to shut off the burner if there is any fault, the electrical panel has a safety relay (LX) with a contact connected in
series with the burner if the equipment safety thermostat is triggered (LM) or when the fan assembly stops due to the
activation of the motor thermal relay.
