Routing through a shaft (type C
The boiler draws combustion air from the atmosphere through the
annular gap inside the shaft (chimney) and expels the flue gas via the
flue pipe above roof level.
The shaft is not part of the standard delivery. For a detailed description,
see pages 26 to 28.
Retrofitted shaft
For installation into a retrofitted, Building Regulations-approved shaft
made of shaft elements or mineral profiles.
For a detailed description of shafts, see page 18.
Routing over external walls
(type C or C , to TRÖl 2009)
53x 53
The boiler draws combustion air from the atmosphere via a horizontal,
concentric coaxial pipe on the external wall and expels flue gas to the
atmosphere via the roof.
In its vertical section, the outside pipe of the concentric coaxial pipe
acts as thermal insulation thanks to its static air gap.
The combustion air is supplied via the balanced flue air inlet.
For a detailed description, see page 29.
