A flue safety thermofuse (12) is present on the outlet of the
flue hood, placed to protect the flue extraction elements when
the temperature of the combustion products exceeds 115°C,
by blocking boiler functioning.
An exchanger safety thermal fuse (13) is also inserted on the
condensation module to protect the module itself, which inter-
venes when the temperature detected inside the condensation
module exceeds 167° C.
Condensate drain trap (4).
Collects the condensate that forms during boiler functioning
from the bottom of the module.
Its outlet is connected to the draining pipe (11) towards which
the passage of water is allowed but not the passage of combu-
stion products, which could occur following obstruction of
the evacuation pipes.
The height of the column of water in the siphon is in fact
greater than the pressure detected inside the sealed chamber
(
module
) with the fan at maximum speed and the evacuation
pipes blocked at functioning limits.
This, however, prevents the draining of combustion products
into the sewers.
Flue circuit.
Operation.
The functioning of the fan positioned at the entry of the air-
gas mixing pipe, guarantees the fan-assisted expulsion of the
combustion products (5).
These directly hit the first
two elements
(
version 12 2 I
)
or
three elements
(
version 26 2 I
) of the primary heat exchanger
inserted in the sealed combustion chamber (6), which has
a sheet steel section on its base (7) that divides it from the
condensation chamber (2) and diverts the flow of combustion
products to the outside of the module.
In this way the flue gases, before entering the condensation
chamber (2), hit
the last element
(3) of the heat exchanger,
inside which, primary circuit return water runs.
This cools the combustion products further and makes their
condensation easier before escape from the flue hood (1), which
is an integral part of the module.
The water condensate formed inside the heat exchanger, in
the flue hood and also in the evacuation pipes flows into the
lower part of the module from where, before being discharged,
is conveyed into a trap (4). Any water formed in the intake
pipes is collected in a valley gutter (14) and by means of a
silicone pipe (10) is conveyed into the siphon (4) to then be
drained away.
Flue hood (1).
It is connected to the rear part of the condensation module
and conveys the combustion products towards the drain fitting
present in the upper part of the appliance.
It is affected by the passage of combustion products and water
condensate formed inside it or in the exhaust pipes.
It is constructed in plastic, resistant to the corrosive effects of
the condensate and can work to a temperature of 130 °C (
max.
flue temp with flow 85 °C = 78 °C
).
