The proper functioning of the chimney
requires adequate sizing of the chimney
itself since the draught it produces affects
combustion, boiler’s output and life span.
The draught created by the chimney
is in functional relation to its cross-
section, height and the roughness of its
interior walls.
No other appliance may
be connected to the chimney serving the
boiler. Chimney diameter must not be
smaller than the flue outlet of the boiler.
Flue outlet must be connected to the
chimney opening. In terms of mechanical
properties, the flue outlet must be sturdy
and properly sealed (to avoid gas leak)
and allow for easy access for cleaning
on the inside. The inner section of the
flue outlet must not be greater than the
effective section of the chimney and must
not narrow. Avoid using elbow joints.
The chimney cleaning opening has to be
in its lowest part. The chimney’s wall has
to be threeplied where the medium layer
is from mineral wool. The thickness of the
insulation is not less than 30 mm when
the chimney is setting up inside the house
and the thickness is 50 mm, when the
setting up is outside.
The inner diameter of the chimney
depends on its real height and the power
capacity of the boiler (see diagram 4).
Please entrust choosing a chimney and
its installation by a qualified professional.
The required distance between the boiler
and the chimney is 300-600 mm.

Data in the tables are for
indicative purposes.
Draught depends on the
diameter, height, uneven sections
along the chimney surface and
differences in temperature of
combustion products and outside
air. We recommend that you use
chimney fitted with flue terminal.
Heating specialist must calculate
the precise sizing of the chimney
.
7.2 Connecting the safety heat exchanger
Such connection must be
performed by a technician /
service shop authorized for such
operations.
The heating boiler is equipped with
safety heat exchanger (cooling circuit). It
connects to the water system through a
thermostatic valve. In case of overheating,
the thermostatic valve feeds in cold water
from the water mains which passes
through the heat exchanger and absorbs
the heat in the boiler. The water is then
discharged into the sewage system. This
arrangement ensures safe evacuation
of the excess heat without the need for
additional energy. This guarantees that
the water in the boiler will not exceed the
maximum safe level of
95°C
.
The minimum operating pressure of the
cooling water in the safety heat exchanger
must be within the range
2 ÷ 10 bar
.
A flow rate of at least 12 l/min is required.
