Example of a vertical duct route
• Apply the seal to the coaxial vertical
adaptor (O);
• Carefully insert the O- ring (J) into the
inside part of the vertical adaptor;
• Put the vertical adaptor on the boiler’s and
fan’s outlets;
• Insert the coaxial extension (M) into the
vertical adaptor;
• For passage through the roof cover,
use either special roof tiles (so-called
“ventilation tiles”) or a roof flashing
custom-made by a tinsmith;
• The coaxial extension duct protruding
above the roof should be terminated with
a coaxial (“Meindinger”) head. Instead of
the extension duct and head, a vertical
terminal (L) is better to use as the nicer
top part.
• Attach a condensate-drainage part (tube,
hose, etc. – not included in the delivery)
to the condensate outlet of the vertical
adaptor;
