Air/Flue Gas Routing - Wolf COB-2 Operation Instructions Manual

Planning
4.7.5 Air/flue gas routing
Separate concentric balanced flue
NOTE
Flue gas can be drawn back in through adjacent flue outlets.
Heat generator faults
► Maintain a clearance of 600 mm.
► All outlets must be at roughly the same height
Do not exceed the maximum permissible route length.
The calculated length comprises the straight pipe length and the length of the pipe bends. In this
calculation, an 87° bend is calculated as being 2.0 m and a 45° bend as being 1.2 m.
Maximum permissible route length:
– DN 80/125 max. 18 m
– DN 110/160 max. 14 m

DANGER
Escape of flue gases!
Risk of asphyxiation or severe to life-threatening poisoning.
► A flue cascade is only permitted with a tested flue gas damper.
Design according to EN 13984-1. Comply with all building regulations and requirements in your country.
Heat generators with common flue routing are only suitable for open flue operation (type B23). There
must be an aperture in the installation room that opens to the outside and has a clear cross-section of at
least 150 cm².
In addition to the bends connected to the heat generator, a maximum of two 87° diverters may be
installed.
