1.3.2 Air supply and flue gas exhaust in a closed
installation
A ventilation cover is integrated into the 600 Series condensing
gas boilers. This cover houses a number of components, such
as the burner and the heat exchanger. Since this ventilation
cover is part of the air supply system, it is vital that it is always
installed correctly.
To ensure optimal operation, the 600 Series appliances must
be connected to a Buderus wall-mounted or roof-mounted flue
terminal. These terminals have been developed specifically for
the 600 Series condensing gas boilers and have been
comprehensively tested. The Buderus wall and roof-mounted
flue terminal kits ensure trouble-free operation.
The following items for the flue (see fig. 2) are included in the
delivery of the boiler:
– pos. 1: 1 Concentric bend 60/100;
– pos. 2: 1 Horizontal flue terminal 60/100;
– pos. 3: 1 Flue finishing kit.
1.3.3 Maximum Flue length
The maximum pipe length of the air supply and flue gas
exhaust pipes for the 600 Series condensing gas boilers (see
table 2) is determined by the total pressure loss of all
components in the flue gas exhaust / air supply system.

Take the flue conduit clearances into account when planning
the layout of the place of installation (see subsection 1.3.1:
"Siting the flue terminal" on page 9).
Maximum wall thickness without extensions is 550 mm.
Maintain a minimum side wall clearance of 50 mm (see fig. 3).
1.3.4 Additional flue parts
Additional flue parts (see table 3) can be ordered from your
supplier.
Subject to modifications resulting from technical improvements!
