Gas-heated Miele tumble dryers are type B
stallations without flow safeguarding equipment, and with a fan be-
hind 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.
- Vent ducts for exhaust air and exhaust gas must be kept as short
as possible. The 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 vent
ducting. The condensate must be drained via a water collection tray
or a floor drain positioned in an appropriate location. No filters or
grilles may be fitted in the pipeline. The vent ducting for exhaust air
and exhaust gas must be installed leak-tight.
The latest guidelines for approving exhaust gas systems containing
low-temperature exhaust gases must be observed.

Where it is not possible for evacuation to take place through a
single duct, appropriate measures must be put in place to en-
sure that the exhaust gas/air mixture from the machine is not
able to enter the room in which the appliance is located via the
exhaust duct for other appliances (e.g. through the use of
baffles and merged lines with a shape that is favourable for the
flow). When using a shape that is favourable for the flow, it is im-
