Installation of a balanced flue system

In tight spaces, CO

value and flue gas tempe-

rature can be tested immediately downstream of the

boiler at a connection adaptor with inspection piece

(80/125 system) or alternatively at an inspection piece with

connector (60/100 system).

The flue gas test ports must remain accessible to

the relevant authorities, even after fitting the ceiling

bezels.

Fig.: Example: Balanced flue system

For concentric air/flue pipes (balanced flue systems),

use only original Wolf components.

Please observe the technical information regarding

balanced flue systems prior to installing the flue pipe

or the ventilation air connection.

Different countries have different regulations. We

would therefore recommend you contact the appro-

priate authorities to check local requirements.
