7. SETUP OF THE HEATING BOILER
7.1. Connecting the boiler to a
chimney
Boiler-to-chimney connection must
always comply with the existing
standards and rules. The chimney
must provide sufficient draught for
extracting of the smoke under any
conditions.
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 at the
same time. 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.
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.
The inner diameter of the chimney depends on its real height and the power capacity
of the boiler (see diagram 5). Please entrust choosing a chimney and its installation
