1.6 GENERAL SERVICES
1.6.1 The Fume Channel/Combustion Air Intake
The combined fume channel and combustion air intake requires one of the following
concentric ! ue system con" gurations.
Important: Due to the high temperature of the outer walls
(approx. 150°C), no ! ammable materials may be located
or used in the vicinity of the ! ue system.
The complete ! ue system, must therefore be sleeved
with a heat resistant material after assembly.
Ventilate the covered concentric ! ue by " tting a
grid near the ! oor and ceiling (on each ! oor).
Do not insulate the concentric ! ue.
Use the universal wall/! oor support Ø150 mm
to attach the covering of the concentric ! ue system
[Ø100 mm - Ø150 mm], see 1.6.2, drawing number 36.
