•
maui KR 115-280 devices feature a flue gas vent probe which will immediately stop thermal unit operation if flue gas
temperature rises in an abnormal way.
•
in the "C” configuration, the device draws the combustion air from outside the installation room which therefore DOEs NOT
require aeration openings.
•
it is recommended to use stainless steel ducts according to EN1856-1 and EN1856-2 for the flue gas ducts. in case PPs ducts are
used, they must be certified and equipped with a condensate collector placed before the connection of the thermal unit flue.
•
it is compulsory to use terminals compliant with the EN1856-1 standard requirements.
•
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 operate the device if the flue gas vent ducts and combustion air intake ducts are unsuitable.
•
Arrange for a 3% inclination of the flue gas vent duct toward a condensate collector.
upon delivery, the thermal unit is in the B23 configuration.
To draw air from the outside it is necessary to connect a plastic pipe with diameter 100 to the intake outlet of the device.
To suck air from the outside it is necessary to connect a plastic tube (d. 100) to the device intake terminal keeping in mind that such
duct must not feature a flow resistance higher than the value specified in the table below.
Gas supply and flue gas vent should be in an area having the same pressure.
The protection net placed at the air duct inlet prevents foreign bodies from entering.
Flue gas exhaust and air supply calculations: the table below indicates the total residual head available for the flue gas exhaust
and the combustion air intake.
Make sure that the necessary head does not exceed the values specified in the table, otherwise the pressure switch could trigger
and block the thermal unit.
