The flue gas mass flow of the plant depends on the burner output
of the ROTEX GCU compact.
4.5.2 Connecting a flue gas line
Requirements
– The flue system fulfils the requirements described in
section 4.5.1.
– The flue system fulfils any other required national or regional

are also fitted with special acid-proof seals.

In some cases, the resonance in the flue system can
amplify the noise at the mouth of the flue gas pipe. The
noise level can be effectively reduced with the applica-
tion of a silencer (E8 MSD, 15 45 78 bzw.
E11 MSD, 15 45 79).
