Notes on the exhaust gas system
Temperature-resistant exhaust gas pipes for high exhaust gas
temperatures
The exhaust gas pipes must be temperature-resistant to 400°C [752°F].
Due to high exhaust gas temperatures, do not use exhaust pipes made of
aluminium or of any materials that are not temperature-resistant up to
400°C [752°F].
Flue pipes must be sealed and installed in accordance with local standards. Con-
tinuous suction must be ensured. In the event of back pressure, the safety tem-
perature limiter in the flow safety device triggers. The safety temperature lim-
iter is set to 103°C [217.4°F].
