Room Ventilation Opening For Air Intake From The Setup Room - Miele PDR 914 Operating And Installation Instructions

Room ventilation
opening for air in-
take from the
setup room
The vent ducting must not be channeled into a chimney or flue already
in use for any gas-, coal-, or oil-burning installation. The warm and
moist exhaust air is to be conducted outside or to a suitable venting
duct over the shortest path possible. The vent ducting must be laid so
that air flow is not hindered. To achieve this, use as few bends as pos-
sible along with short pipelines and well-made connections and tran-
sitions checked for air-tightness. No filters or grilles may be fitted in
the vent ducting.
The end of the vent ducting leading out into the open should be pro-
tected against the elements, e.g., with a downward-facing 90° bend.
 During tumble dryer operation, the room must be adequately
ventilated.
The minimum dimension of the ventilation opening depends on the
cross-section of the vent duct.
