Maximum allowable length of the flue duct up to common
chimney is 2 metres + 1 60/100 90° elbow.
Subtract equivalent length value of bends from the allowable flue
length value.
Type B53 (open flue system)
The boiler draws combustion air from the installation room and
expels flue gas through the flue to above the roof (1).
The boiler draws combustion air from the installation room and
routes flue gas through the moisture-resistant chimney to above the
