LEVEL.: Connect the level switch (water level sensor) to terminals 20
and 21. This is used to signal low water level inside the heating cooker
boiler unit.
(Terminals already connected to level switch in the factory).
The flue pipe and connection to the same
The flue is an essential component for the heating cooker/heating
stove's efficient operation. The heating cooker/heating stove smoke
outlet is 150mm in diameter. The minimum cross section of the flue
pipe should be 180 mm. Every heating cooker/heating stove must
have its own flue pipe, without other adjoining elements (boilers,
chimneys, stoves etc.). The flue dimensions are closely related to
its height, which must be measured from the heating cooker/heating
stove flue gas outlet to the base of the chimney stack. In order to
guarantee draught, the stack flue outlet surface must be twice as
big as the flue cross-section. The combustion gases exhaust pipe,
generated by the natural draught appliance, must respond to the
following requisites:

It must seal off the combustion gases, besides being
waterproof and suitably isolated and insulated in relation to
the conditions of use (refer to UNI 9615);

It must be made of suitable materials capable of
withstanding normal mechanical stress, heat, and the
effects of combustion gases and condensate, if any;

It must go upwards after the vertical section, for the entire
remaining part, with 20% minimum gradient; The sub-
horizontal section must not have a length greater than ¼ of
the effective height H of the flue or chimney, and must not
be longer than 2,000 mm;

Preferably with a circular internal cross section: squared
and rectangular cross sections must have rounded corners
with a radius larger than 20 mm;

It must have a constant, free and independent internal
cross section;

Rectangular cross-sections must have a maximum ratio of
1.5 between the sides;

If the flue is installed outside it is essential that it is
insulated in order to avoid the flue gas cooling and the
formation of condensate;
