Example of a vertical route of dual tubing
– design C32 (according to EN 483) is il-
lustrated in Fig. 18.
Method C
42
– connection to common dual
chimneys. Dual tubing from each boiler
(individual routes) may be terminated in
a common chimney; the chimney’s trans-
portation sufficiency is assessed from the
data stated by the manufacturer of the
chimney flue used. If the routes are termi-
nated in the chimney in mutually perpen-
dicular directions, the minimum vertical
distance between them must be 0.45 m. If
the routes are terminated in the chimney

from opposite directions,the minimum ver-
tical distance between them must be 0.60
m. Outlets of routes terminated in a com-
mon dual chimney must never be fitted
with end pieces (used in routes dischar-
ging to free space)! Both route sections
(the outside – air, and the inside – com-
bustion gases) must be safely inserted
into the chimney inlet, but not too deep,
so that it does not form an obstacle to the
flowing combustion gases or air.
In this case the route of the concentric
tubing must not exceed the length (elbow
90° +) 3 Em; the separated tubing rou-
te must not exceed (elbow 90° +) 9 Em
(when adding the length of the air and
combustion gas sections together).
Method C
52
– dual tubing separated and
terminated at two different points (with dif-
ferent specifications, mainly pressures).
Separate tubing can also be used to re-
move combustion gases and supply com-
bustion air (see Fig. 19). The separate
tubing routes must not be terminated at
mutually opposite building walls.
Method C
62
– connection to independent-
ly approved and handed over tubing.
In this case the tubing must have a nomi-
nal size according to the boiler’s technical
parameters and valid for the same per-
mitted lengths as are cited in this part of
the Instructions for individual installation
examples (Methods CXX) – the lengths
were determined by experience and no
formula are used to calculate them. Only
corresponding components (end pieces)
of the approved and supplied tubing are
used for connecting the boiler and outlet/
inlet termination of tubing into free space
