Installation
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 horizontal or vertical flue terminal.
These terminals have been developed specifically for the 600
Series condensing gas boilers and have been comprehen-
sively tested. The Buderus horizontal or vertical flue terminal
kits ensure trouble-free operation.
Horizontal flue pack:
– pos. 1: 1 Flue turret 80/125 to 60/100 (NE 87603);
– 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 compo-
nents in the flue gas exhaust / air supply system.
Flow pressure available for use [Pa]
600 - 28C
Take the flue pipe clearances into account when planning the
layout of the place of installation (see see subsection 1.3.1:
"Siting the flue terminal" on page 8).
Maximum wall thickness without extensions is 550 mm.
Maintain a minimum side of 100 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!
