The maximum length corresponds to the total length from the appliance to the flue terminal.
For available lifting pressures of gas fans, see specification.
Note: Systems C33x and C83x are also suitable for
installation in garages.
Where necessary, adapt the installation examples to the
relevant building regulations and requirements in your
country/region. Any questions relating to the installation,
particularly regarding the provision of inspection
components and ventilation apertures (ventilation generally
required above 50 kW output) should be raised with your
local flue gas inspector prior to installation.
The specified lengths refer to concentric balanced
flues and standard flues, and apply to original Wolf
components only.
Balanced flue systems DN60/100 and DN80/125
are certified as single units together with Wolf gas
condensing boilers.
The following balanced flues or standard flues with
CE-0036-CPD-9169003 certification may be used:
- Flue pipe DN80
- Concentric balanced flue DN60/100 and DN80/125
- Flue pipe DN110
-
Concentric balanced flue (on external walls) DN80/125
- Flexible flue pipe DN83
Wolf accessories are supplied with the relevant necessary
identification labels.
Please also observe the installation information supplied
with the accessories.
