Pressure drop calculations
The first 90 ° bend must be mounted directly to the boiler and followed by the chimney silencer (this bend is not part of the calculation (as it is already
taken into account)).
Flue-outlet and air-supply calculations ;
Total pressure drop available for flue-outlet and air-supply is given in the table below.
