HOW TO USE THE BOILER
An example of a level coaxial pipe route:
version C
12
(complies with STN EN 483)
The C
8.15.3
32
method
Vertical routes and vertical venting into an
open space.
Length of fume ducting (23 MTV):
60 / 100: min. 1 m (with one 90° joint),
-
max. 4 m (with one 90° joint). If the total
fume ducting length is more than 1.5 m,
the diffuser with a diameter of 39 mm
must be removed.
80 / 125: min. 1 m (with one 90° joint),
-
max. 10 m (with one 90° joint). If the
total fume ducting length is more than
1.5 m, the diffuser with a diameter of 39
mm must be removed.
An example of a vertical coaxial pipe
route: version C
32
(complies with STN EN
483)
The C
8.15.4
42
method
Connecting to a double shared chimney.
Double piping from independent boilers
(independent routes) can feed into shared
chimneys; the transport capacity of
the chimney is judged according to the
manufacturer’s data on the chimney. If
the pipes are set into the chimney in two
directions and vertically aligned, there
must be a vertical separation between
the outlets of at least 0.45 m. Where two
outlets vent towards each other, they
must be separated by a minimum vertical
distance of 0.6 m. The exhaust piping into
the shared double chimney never has
terminal elements — the same as with
pipes that vent into open areas!
Both components of the route — external
(air) and internal (exhaust gas) — must
safely feed into the relevant chimney duct
but not protrude so deeply that they create
blockages in the exhaust or air ducts.
Length of fume ducting (23 MTV):
60 / 100: min. 0.3 m (with one 90°
-
joint), max. 3 m (with one 90° joint). If
the total fume ducting length is more
than 0.5 m, the diffuser with a diameter
of 39 mm must be removed.
