e central heating circuit, with relevant control and safety
devices, is operated every time a central heating request is
made.
Operation.
e heat contained in the fumes produced by combustion
is absorbed by the copper blades of the water-gas exchanger
(7) which, in turn, transfers it to the water circulating inside
thanks to the boiler circulator (16).
e hot water is then transferred directly into the central heat-
ing system through the delivery (M) and return (R) pipes.
