Regulations

In accordance with the [German] Technical Rules for Gas
Installations DVGW-TRGI 2008, the contracted installer
must seek the agreement of the responsible flue gas
inspector prior to commencement of work on the flue
system or notify the flue gas inspector of the installation in
writing. In this connection, observe the relevant national
and regional regulations. It is recommended to ask the
flue gas inspector to confirm his participation in writing.
Gas combustion equipment must be
connected to the flue on the same floor
where it is installed.

flue systems are as follows:
• EN 483
• EN 677
• DIN-EN 13384-1 and DIN-EN 13384-2

System certification

The flues of the Buderus sets GA, ÜB-Flex with GA, GA-X
with GA-K, ÜB-Flex with GA-X and GA-K, the sets of the
flue cascade, GA-X with LAS-K for the connection to a
moisture-resistant flue system (LAS multiple connection)
and GN are system-certified together with the
Logamax plus GB162 gas condensing boiler for open
flue operation.
The system certification complies with the Gas
Appliances Directive 90/396/EEC as well as the EN 483
and EN 677 standards. Joint approval of the Buderus set
with the appliance is documented by the corresponding
CE designation. The CE designation is listed in the
technical guide of the relevant gas condensing boiler. No
additional CE approval of the flue system is required.
The limits of application of the Buderus sets for open flue
operation of the Logamax plus GB162 have been
finalised. Special determinations for the implementation of
the respective flue or air/flue pipe, the maximum
permissible overall flue length and the number of
diversions within the flue line are summarised on
pages 116 to 126.
A calculation of the flue system to DIN-EN 13384-1/2 is
not required. The manufacturer of the moisture-resistant
chimney or air/flue gas system must only calculate the size
of the moisture-resistant chimney in connection with the
Buderus GN and LAS-K sets.
