pipe (11) which is connected to the negative pressure point
of the flue pressure switch (6)
and to the pressure point on
the fan
.
The positive pressure point (10) is connected directly to the
inside of the sealed chamber.
Flue flow meter (6).
It is positioned in the lower external part of the sealed chamber
and detects, through the relevant point, the pressure difference
between the inside of the fan (negative signal) and the inside
of the sealed chamber (positive signal) .
The signal generated by the flue flow meter (6) is managed by
the circuit board in order to adjust fan speed (5), in a way to
maintain the pressure difference constant at a value between
60 and 90 Pascal (between 6.1 and 9.2 mm. H
2
O) , which can
be measured by the relevant pressure sockets (9-10).
When the pressure reaches the value set on the integrated
P.C.B. the burner can be ignited.
Fan (5).
The flue discharging fan operates downstream from the com-
bustion chamber and is physically installed on the upper part
of the flue hood (4) from where it extracts flue and directs
them to the flue system ducts the boiler is connected to. At
the same time, it ensures combustion air flow into the sealed
chamber.
The fan is controlled by the integrated P.C.B. and its function
essentially follows the burner operation.
Air/flue sample points (7-8).
There are two sample points on the upper side of the sealed
chamber (they are accessible from the front), which can be used
to take samples of combustion air (7) and flue (8).
The two sample points are closed by one single plastic plug.
(13).
Flue pressure switch signal pressure points
(9-10).
In the lower external part of the sealed chamber, there are two
pres sure points, which can be used to verify the signal on either
end of the flue pressure switch (6).
The negative pressure point (9) is connected to a silicone
