14. Air/flue gas routing

At low outside temperatures, the water vapour

contained in the flue gas may condense and freeze

on the flue. Prevent falling ice through on-site

measures, e.g. the installation of a suitable snow

catcher grille.

The flue gas test ports must remain accessible for

your local flue gas inspector, even after fitting the

ceiling bezels.

Please

note

Fig: Example: Air/flue gas routing

For concentric balanced flue systems, use only

original Wolf parts.

Prior to installation, read the technical information

regarding air/flue gas routing.

As regulations in the individual Federal States

[Germany] differ, we recommend consulting the

relevant authorities and local flue gas inspector

prior to installation.

Please

note

Inspection and testing intervals

The gas condensing boiler is equipped with self-cal-

ibrating control of the combustion process. Under

the Bundes-KÜO (German Federal Sweeping and

Inspection Act), inspection and testing of this gas

boiler is only required every 3 years [Germany]. This

must be done by a flue gas inspector.
