The boiler should only be installed with a fresh air inlet and smoke outlet device supplied by the boiler manufacturer.
The kits are supplied separately from the boiler to meet the requirements of various types of installation. For more information
about inlet/outlet accessories, refer to the accessories catalogue and the installation instructions inside the kits. The boiler is
pre-equipped for connection to coaxial or twin flow air intake and burnt gas outlet systems.
Warning
The exhaust gas ducts should not be in contact with or close to
inflammable material and should not pass through building structures or
walls made of inflammable material.
When replacing an old appliance, the gas intake and exhaust duct system
will also have to be changed.
Important
Ensure that the gas intake and exhaust
passages are not blocked.
Ensure that the exhaust gas ducts do not
have leaks.
5.2 TWIN FLOW FLUE TYPE (C12, C32, C42, C52, C82) xy
There is also the possibility of using an exhaust gas duct with separate tubes by using
an adaptor on the outlet header and by inserting the tube in the air intake envisaged for
this purpose.
In order to use the air intake, you should:
1) Take the air intake cover off
2) Assemble the flange on the header supplied with the boiler
3) Assemble the membrane, if necessary, on the tube or the elbow
4) Insert the header on the tube or the elbow up until the lower stop
(you do not have to use the washer).
5) Insert the elbow/header in the boiler air intake hole and fasten it with screws.
If the two elbows or in
the same lateral
direction and if you
need to reduce the
required space, the
minimum 230 mm
measurement can be
reduced by carefully
cutting the elbow below
the air inlet by 25 mm.
