Flue circuit.
Operation.
The products of combustion, after having hit the water-gas
exchanger (2), are slowed down and distributed by the plate
(12) thus increasing combustion efficiency. They are then
conveyed to a draught diverter (4) on top of which the flue
extractor (fan) (5) is mounted.
Fan operation ensures forced expulsion of the flue and, at the
same time creates a vacuum in the sealed chamber (3) so the
combustion air can be extracted from outside.
Correct fume extraction is controlled by a differential flue pres-
sure switch (6) that enables or prevents burner ignition.
Air-flue intake traps (7-8).
The top outer part of the sealed chamber features two intake
traps with screw closing, accessible from the front and from
where combustion air (7) and flue (8) can be sampled.
Flue pressure switch signal pressure points (9-10).
The top outer part of the sealed chamber features two pressure
points with screw closing by means of which it is possible to
measure the signal on the ends of the flue pressure switch
(6).
Only for 24 kW model.
(Up to serial number 2738489 for EOLO Maior 24 kW)
The negative pressure point (9) is connected to a “Y” shaped
pipe (11) which, in turn, is connected to the negative pressure
point of the flue pressure switch (6) and to the pressure point
positioned at the outlet of the Venturi pipe inserted in the
fan’s exhaust terminal.
The positive pressure point (10) is connected directly to the
inside of the sealed chamber.
Only for 32 kW model.
(to start production)
The negative pressure point (9) is connected to a “Y” shaped
pipe (11) which, in turn, is connected to the negative pressure
point of the flue pressure switch (6)
and to the pressure point
(1) positioned at the fan’s exhaust terminal.
The positive pressure point (10) is connected directly to the
inside of the sealed chamber.
