3.4.1 The Fume Channel/Combustion Air Intake
The combined fume channel and combustion air intake requires one of the following
Barbas concentric fl ue system confi gurations.
Important:
Due to the high temperature of the outer walls
(approx. 150°C), no fl ammable materials may be
located or used in the vicinity of the fl ue system.
After installation, encase the entire concentric fl ue
system with a heat resistant material between the
fl oor of the fi rst storey and the outlet.
Ventilate the covered concentric fl ue by fi tting a
grid near the fl oor and ceiling (on each fl oor).
Do not insulate the concentric fl ue.
Use the universal wall/fl oor support Ø150 mm
to attach the covering of the concentric fl ue system
[Ø100 mm - Ø150 mm], see 3.4.2, drawing number 36.
