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 circuit complete with circulating pump, safety valves, air vent, temperature probes and pressure
transducer.
During insert 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.
