This table is based on material provided by ACV and cannot be generalised.
Exampleofcalculation:
The following diagram consists of
the following components (Ø 80 mm) :
•1x90°Bend
•2xPipeL2000mm
•2x45°Bend
•2xPipeL1000mm
•1xVerticalterminal
•1xCondensatetrap
Calculation:
•1x4,32 = 4,32
•2x5,1 = 10,2
•2x2,75 = 5,50
•2x2,55 = 5,10
•1x5,4 = 5,4
•1x2,06 = 2,06
Total: 32,58 x 2 = 65,16 Pa
As this value
is lower than
themaximum
permissible
resistance,
this installation
is compliant.

A drain outlet must be provided near the boiler to
prevent condensation from the chimney entering the
