7.1. Connecting the boiler to a chimney
Diagram 4
Boiler-to-chimney connection must
always comply with the existing standards
and rules. The chimney must provide
sufficient draught for evacuation 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. 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.

Draught depends on the diam -
eter , height, uneven sections
along the chimney surface and
differences in temperature of
combustion products and out -
side air. We recommend that
you use chimney fitted with
flue terminal . Heating specialist
must calculate the precise sizing
of the chimney .
