Where necessary, adapt the installation examples to the
relevant Building Regulations and requirements of your
country/region. Discuss any questions relating to the
installation, particularly of inspection pieces and ventilati-
on apertures (ventilation generally required above 50 kW
output) prior to installation with your local heating engineer/
flue gas inspector.
The length dimensions refer to concentric balanced flue
and flues, specifically only to original Wolf components.
Balanced flue systems DN60/100 and DN80/125 are
certified as systems together with Wolf gas condensing
boilers.
The following balanced flue or flues with CE-0036-
CPD-9169003 certification may be used:
- Flue DN80
- Concentric balanced flue DN60/100 and DN80/125
- Flue DN110
- Concentric balanced flue (on an external wall) DN80/125
- Flue, flexible DN83
The necessary type plates are supplied with the respective
WOLF accessory.
Observe all additional installation instructions included with
accessories.
