This tumble dryer is a gas-burning machine without a flow-
operated safety device with fan downstream of heat
exchanger.
Technical design: B22 (as standard)
Waste gas pipework must be pressure-tight.
Waste gas connections should be performed in accordance
with national and local regulations and may require approval.
Note installation instructions for gas-heated Miele tumble
dryers.
As relative humidity inside the vent ducting can be as high as
100%, suitable measures must be taken to prevent a
backflow of condensate into the machine.
Air intake
Standard connection: Air intake from installation site
Unobstructed air intake into room recommended (corres-
ponding to 3 times the vent cross-section of machine)

A sufficient supply of fresh air should be ensured to
replace the air extracted.
