•
maui KR 115-280 devices feature a flue gas vent probe which
will immediately stop device operation if flue gas temperature
rises in an abnormal way.
•
In this configuration, the device draws the combustion air from
the installation room which MUsT HAVE aeration openings
compliant with the prescriptions of the Technical Standards.
•
It is recommended to use stainless steel ducts according to
EN1856-1 and EN1856-2 for the flue gas system duct.
•
The chimney must ensure the minimum vacuum defined by
the prevailing Technical standards, taking into account a "zero”
pressure at the flue gas system duct connection, and it must
feature a condensate drain. The boiler condensate drain must discharge only the condensate coming from the boiler and from
the flue gas system duct
•
Connect the condensate collector trap with a white water drain.
•
Vent ducts, if not insulated, are potentially dangerous.
•
the size of the chimney must correctly suit the condensing thermal units. chimneys and flue gas system ducts of
unsuitable type or size may cause problems to the combustion parameters and generate noise.
•
it is FoRBidden to close or reduce the size of the aeration openings of the installation room or of the device.
•
Arrange for a 3% inclination of the flue gas vent duct toward a condensate collector.
