Primary exchanger (1).
It is a lamellar water-gas exchanger with copper tubes and fins
and at whose outlet (flow) the central heating NTC flow probe
(6) and the overtheating safety thermostat (2) are located.
The four pipes it is made of are connected in series (1).
It is connected to the circulator flow and to the primary circuit
flow by means of push-fitted pipes (3) and O rings (5) and
locked with forks (4).
The exchangers of the 24 and 28 versions differ in the number
of fins (86 in the 24 version and 103 in the 28 version) and in the
different layout of the flow and return pipes (see drawing).
