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.
The pellet stove has an internal heating water circuit complete with circulating pump, safety valves, air vent,
