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
For the air intake/flue gas venting systems, specific, manufacturer approved, condensate acid-resistant pipes and sy
-
stems must be used, suitable for condensing boilers.
DANGER
In the case of passages through walls with split or coaxial air intake and gas venting ducts, always seal any space betwe-
en pipes and walls.
If the wall is made of flammable material, apply fireproof insulating material around the flue gas venting pipe.
DANGER
For boilers with split air intake and flue gas venting ducts, in the case of passages through flammable walls, apply fire
-
proof insulating material around the flue gas venting pipe.
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.
After each operation on the safety device or the air suction/flue gas exhaust system, it is necessary to perform a functio
-
nal test of the boiler.
In case it is necessary to replace the safety device use only original spare parts supplied by the Manufacturer.
