3.2.6.
Air intake / flue gas discharge system
Flue gas discharge into the atmosphere must comply with applicable laws and standards in the country of installation.
The boiler is equipped with safety devices checking correct flue gas dischargeion.
Should an air/flue gas system malfunction occur, the safety devices shut down the boiler and the LCD will display the
burner shutdown symbol
and flashing E03 code.
It is strictly forbidden to tamper with and/or prevent operation of such safety devices.
Should the boiler repeatedaly shut down, it is necessary to have air/flue gas system ducts inspected, as they might be
obstructed or inadequate to flue gas discharge into the atmosphere.
In air intake/flue gas discharge systems, specific, manufacturer approved, condensate acid-resistant systems for
condensing boiler are to be used.
Flue gas discharge pipes are to be installed tilted toward the boiler so that condensate runs in the direction of 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 discharge system, with the exception of
the condensate drain siphon eventually connected to the discharge system itself.
The manufacture shall not be held liable for damage resulting in incorrect installation, use, modification of the equipment or non-
observance of instructions provided by the manufacturer or applicable installation standards involving the product.
