flue gas outlet to the chimney inlet is necessary, it should
be executed as a slender cone.

Dimensioning the flue gas pipe cross-section. The cross
sec tions are to be calculated for boilers without delivery
pres sure requirement according to EN 13384. (Please
note also DIN 18160, part 1 “House chimneys”). Take in to
account the local, special situation (position of the house
on a slope, position of the flue gas pipe, roof pitch, flue
gas exit shape etc.)!
In Switzerland, take note of SIA Recommendation 384/4!
In Austria the calculation is carried out according to
ÖNORM M 7515.
The values for calculation can be obtained
from the table in chapter “3.2 Technical data”,
ref. a)
Chimneys according to EN 13384, part 1/2, execution
types I and II are appropriate for modern firing systems
(advice from the chimney specialist is necessary). Pay
attention to the flue gas temperature at nominal output,
see chapter “3. Technical details”, page 14.

NOTICE
The condensate accumulating in the flue gas
pipe must not flow back to the boiler. A con-
den sate trap (Fig. 22) must therefore be in-
stal led at the flue gas outlet (not included in
the scope of delivery).
