Exhaust gas evacuation ducts
Gas-heated Miele Tumble Dryers are type B
safeguarding equipment, and with a fan behind the heater.
- The mixtures of exhaust gas and air that are emitted by gas-heated tumble dryers must
be evacuated through a suitable chimney and out into the atmosphere via the roof.
- Exhaust-air evacuation ducts and exhaust-gas evacuation ducts must be kept as short
as possible. The evacuation ducts must rise vertically up to the flue.
- Only materials that are resistant to heat and sooting may be used.
- A condensate drain must be placed at the lowest point of the exhaust ducting. The con-
densate must be drained via a water collection tray or a floor drain positioned in an ap-
propriate location. No filters or grilles may be fitted in the pipeline. The exhaust-air or ex-
haust-gas ducting must be installed in a way that ensures it is leak-tight.
See the local guidelines for approving exhaust gas systems containing low-temperature
exhaust gases.
