NOTICE
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.
Continuous suction must be ensured. In the event of back pressure, the safety
temperature limiter in the flow guard triggers. The safety temperature limiter
is set to 103°C [217.4°F].
