Diaphragm installation. For correct functio-
ning of the boiler it is necessary to install a dia-
phragm on the outlet of the sealed chamber and
before the intake and exhaust pipe (Fig. 1-14).
e choice of suitable diaphragm takes place on
the basis of the type of pipe and its maximum
extension: this calculation can be carried out
using the following tables:
N.B.: the diaphragms are supplied together with
the boiler.
