Intake and exhaust systems.
(see intake and exhaust terminals instructions).
The HERCULES Condensing boiler is prepared for connection
to the relevant coupling intake/exhaust pipes and can only be
installed in the home in the following configurations:
- open chamber and fan-assisted circulation (type B
an appropriate intake kit (optional);
- with sealed chamber and fan-assisted circulation (type C)
using the vertical or horizontal concentric kits or the Ø 80/80
separator kit.
For that regarding the head losses relative to each accessory,
for the various combinations that can be performed, see the
instructions relative to the intake and exhaust terminals
(boiler instruction book).
The generators with condensation technology must be installed
using the specific series of intake and exhaust pipes, which have
been designed to be coupled exclusively to the Immergas
condensing boiler.
The "GREEN SERIES" flue kit is made in plastic (PPS = self-
extinguishing polypropylene) suitable for resisting the corrosive
action of the acid condensate.
Configuration with open chamber and fan-
assisted circulation (type B
lation (see figure at the side).
Using a specific kit, the boiler can be installed in the open
chamber and fan assisted configuration (type B
lowing the intake of the combustion agent air directly from
the environment.
Intake.
Intake takes place by making use of the hole present in the up-
per part of the sealed chamber on which, after having removed
the cap present and after having placed the relevant gasket (1),
the relevant terminal support is mounted (2) onto which the
intake terminal is fixed (3).
Exhaust.
The 80 mm diameter exhaust pipe fitting is obtained using the
flange used in the divided systems.
Flue exhaust takes place through the specific pipes with diame-
ter of 80 (4) in an individual flue or directly to the outside.
To prevent condensate problems, the exhaust pipe must be
limited to 30 straight metres.
