Air inlet silencer:
the silencer channels the air once
it has entered the chamber thus
avoiding airflow noise inside the
equipment. Its venturi shape also
aids the airflow.

The heat exchanger:
Is made up of flattened stainless steel tubes in a spiral.
The heat transfer is carried out in two stages:
- the first stage (
A
) uses 5 elements depending on the model (each element has 4 turns), in direct contact with the flame.
- the second stage (
B
) (the cold stage) uses an element placed behind a deflector (
C
). This is heated by the flue products just before
they are evacuated. This is where the condensing occurs.
