– connection to common dual
chimneys. Air can be also supplied from
free space (or from a space with plentiful
air supply). Dual ducting from each boiler
(individual routes) may be terminated in a
common chimney; the chimney’s trans-
portation suffi ciency is assessed from the
data stated by the manufacturer of the used
chimney fl ue. If the routes are terminated in
the chimney in two mutually perpendicular
directions, the minimum vertical distance
between them must be 0.45 m. If the routes

are terminated in the chimney from opposi-
te directions, the minimum vertical distance
between them must be 0.60 m. Outlets of
routes terminated in a common dual chim-
ney are never fi tted with end pieces (used
in routes discharging to free space). Both
route sections (the outside – air, and the
inside – combustion gases) must be safely
inserted into the chimney inlet, but not too
deep, so that it does not form an obstacle
to the fl owing combustion gases or air.
In this case a concentric ducting route must
not exceed the length of 9 Em (for the 28
KTV 5 Em) and a separate ducting route
the sum of the air part and the combustion
gases part must not exceed 18 Em (for the
28 KTV 10 Em).

– dual ducting separated and
terminated at two different points (with dif-
ferent parameters, mainly pressures).
Separate ducting can also be used to remo-
ve combustion gases and supply combus-
tion air (see Fig. 20). The separate ducting
routes must not be terminated at mutually
opposite building walls.
Method C

– ducting with the air part ter-
minated in free space and the combustion
gases part in a common chimney.
Air may also be taken from free space (or
a space with plentiful air supply) and com-
bustion gases discharged into a common
chimney (or back into a space with common
presence of combustion gases). Into this
method falls also the special case descri-
bed in the second paragraph of section
Special cases – see below.
