2.7 Wiring diagram
2.8 Wiring diagram for zone system
Before installing the heating stove in the house, check the type of heating system;
in case of several zones, a special electronic controller for multi-zone circuits, available as an optional, must be
installed. This is to prevent overheating of the heating chamber due to possible simultaneous closing of the zone
valves and consequent stopping of hot water flow.
2.9 Plumbing connections
The heating capacity of the unit must be previously established by calculating the building's heat requirement
according to current regulations. The system must be provided with all the components for correct and regular
operation; in fact according to the rules of proper workmanship in installation, shutoff valves and non-return valves
allowing the stove to be isolated in case of maintenance and/or checks, must be interposed between the stove and
the heating system.
Proceed slowly during heating chamber water filling, to allow correct and complete evacuation of the air from the
vent ( for a closed vessel system from 1.1 to 1.5 bar ).
The pellet stove has an internal heating water circuit complete with circulating pump, safety valves, air vent,
temperature probes and pressure transducer.
If the heating system is managed in zones a multi-zone controller, available on request, must be installed.
To display the boiler's water circuit pressure, just press the control panel button P5 for 3 seconds.
