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 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.
During stove transport the gaskets in the plumbing system may come loose and/or break, causing water
leaks during normal operation; therefore make sure to check the tightness of the circulating pump and
heating chamber connection rings and vent the residual air during water filling and after the first hours of
operation.
To connect the stove to a heating system it is advisable to contact a competent technician in order to best optimise
the plumbing connections and the performance of the entire system without compromising stove operation.
One of the following optionals must be requested for the connection to the DHW circuit:
- a DHW pump on the delivery manifold with respective connection pipes for placing inside the stove
- or a DHW pump, plate exchanger and connection pipes for placing inside the stove
- or a monostable 3-way valve for installing outside the stove.
The request for these accessories must go with the supplementary electronic board model 'Q055' for management
of commands with possible upgrading of software to be placed on the control main board.
After completing the DHW connection it is necessary to access the technical menu of the control and select the type
of circuit; every specific DHW function set: DHW EXCHANGER, BOILER or DHW BOILER appears on the display at
the moment of heating-DHW switchover with one of the messages given below and remains until the end of the
