Instructions for the installer
3.5 Boiler room ventilation
The boiler has sealed combustion chamber. Combustion air is not drawn from boiler room, therefore no specific recommendations need to be
applied concerning the boiler room or openings and ventilation provided to the boiler room.
DANGER
the boiler must be installed in a room that is compliant with the legislation and standards in force in the country of installation,
which are herein considered as entirely transcribed.
3.6 Air intake and flue gas venting system
Flue gas discharge into the atmosphere and air intake/flue gas venting systems must comply with applicable laws and standards in the
country of installation that are considered as fully transcribed herein.
DANGER
The boiler is equipped with safety devices checking correct flue gas exhaustion.
If the air/flue gas system malfunctions, the boiler shuts down and the code E03 is displayed flashing on the display..
It is strictly forbidden to tamper with and/or prevent operation of such safety devices.
Should the boiler repeatedly shut down, it is necessary to have the boiler air intake/flue gas venting ducts checked, since they
could be obstructed or incorrectly sized for flue gas discharge into the atmosphere.
DANGER
For the air intake/flue gas venting systems, specific, manufacturer approved, condensate acid-resistant pipes and systems must be
used, suitable for condensing boilers.
DANGER
Flue gas venting pipes are to be installed tilted toward the boiler so that condensate runs toward the combustion chamber, which
is designed for condensate collection and drainage.
Should the above procedure not be possible, it is necessary to install, in condensate stagnation areas, devices designed for
condensate collection and conveying to the condensate drain system.
It is necessary to avoid formation of condensate stagnation areas in the flue gas venting system, with the exception of the
condensate trap possibly connected to the venting system itself.
The manufacturer cannot be held responsible for any damage caused by inappropriate boiler installation or operation, modification to the
boiler, or due to non-observance of the instructions provided by the manufacturer or of legislation and standards applicable for the materials
installed.
