lengths:
■ Connection pipe 0.5 m long
■ 1 flue bend 87° and 1 support bend
87°
or
■ 2 flue bends 45° and 1 support bend

Open flue operation with combustion air supply via interconnected rooms
Only possible with system sizes 60 and
80.
The connection piece to the shaft is
constructed as part of the balanced flue
system. The combustion air is drawn
from the room via an opening immedi-
ately by the chimney entry (air inlet
adaptor).
An adequate combustion air supply, as
specified by the TRGI 2008, must be
ensured inside the room by means of
an interconnected combustion air sup-
ply:

ted rooms, 4 m
