Installation in "C
15
" configuration of an Immergas boiler, makes it
possible to intake combustion air directly from the shaft where the
flue gas exhaust is present in the dedicated flue.
Information for C15 installations
The boiler is suitable for operating in a C(15)3 or C(15)3X system,
correctly sized by a thermotechnical designer.
The roof terminal, which is an integral part of the project, must
also meet the legislative and regulatory obligations prescribed for
this component. In particular, it must ensure that the degree of
recirculation of the flue gas is always below 10%.
The common supply shaft must be sized so that, in combination
with the intake part of the roof terminal, a vacuum greater than 5
Pa is not generated at the point of the shaft where the boiler draws
the combustion air from the shaft itself, when the boiler works at
maximum heat output and the entire multiple ducting system
works at maximum design power.
If the single terminal complies with the following head losses con-
ditions at the maximum boiler heat input:

in compliance with the conditions described above, the maxi-
mum extensions that can be achieved in the shaft are those de-
fined in this manual with C93 configuration, using the same boil-
er settings.
