Installation room for rated output > 100 kW
In accordance with DVGW-TRGI 2008, gas combustion
equipment with a total rated output in excess of 100 kW
requires a specific installation room. Observe relevant
national or regional combustion ordinances.
2
A vent of 150 cm plus 2 cm
of a total rated output of 50 kW towards the outside must
be provided in the installation room.
For open flue operation, the installation room must meet
the following requirements:
• The installation room must not be used for other
purposes, except the following:
– For routing services into the building, including their
shut-off, control and measuring facilities
– For the installation of combustion equipment for
liquid fuels, heat pumps, CHP modules or
permanently fixed internal combustion engines
– For the storage of fuels
• The installation room must not have any opening to
other rooms except doorways.
• The doors to the installation room must be tight and
self-closing.
• The installation room must be able to be vented.
For solid fuel combustion equipment the rated output
must not exceed 50 kW. If that is the case, the structural
requirements for boiler rooms must be met.
Install an emergency stop switch outside the installation
room in accordance with DVGW-TRGI 2008, section
8.1.4.2 [or local regulations].

Buderus sets
The flue that is part of the Buderus set is made from
plastic. It is installed as a complete pipe system or as a
connection piece between the gas condensing boiler and
a moisture-resistant chimney.
The flue systems are categorised in accordance with
DIN-EN 14471. The flue systems certified by Buderus as
systems correspond to the following classification
( fig. 96):
• System-certified flue systems 1
Internally PP, externally steel, e.g. GA-K, GAF-K, DO
– EN 14471 T120 H1 o W 2 O00 E D L0
• System-certified flue systems 2Internally PP, externally
PP, e.g. DO-S
– EN 14471 T120 H1 o W 2 O00 I D L1
• System-certified flue systems 3Single wall PP, e.g. GA,
GN
– Combined with the Logamax plus GB162, with flue
gas temperatures < 85 °C,
EN 14471 T120 H1 o W 2 O00 I D L applies
– If the approval of the flue system with flue gas
temperatures of 120 °C is utilised,
EN 14471 T120 H1 o W 2 O20 I D L applies
