Instructions for the installer
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 a safety device for flue gas exhaustion check.
It is strictly forbidden to tamper with and/or prevent operation of such safety device.
Should an air/flue gas system malfunction occur, the device will shut-down the boiler by interrupting the gas supply to the boiler
and the LCD will display the E03 code.
In this case it is necessary to have safety device, boiler and the air intake/flue gas venting ducts promptly checked by a service
centre or a qualified service engineer.
In case of repeated stops, it is necessary to have safety device, boiler and the air intake/flue gas venting ducts checked by a service
centre or a qualified service engineer.
After each operation on the safety device or the air suction/flue gas exhaust system, it is necessary to perform a functional test of
the boiler.
In case it is necessary to replace the safety device use only original spare parts supplied by the Manufacturer.
To reset the combustion gas exhaust control device operation it is necessary to press "Reset".
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.
