Exhaust gas evacuation ducts
The PT 825x/830x SL/833x/840x/850x/880x series tumble dryers are type B
burning installations without flow 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/gas evacuation ducts must be kept as short as possible and must rise verti-
cally up to the vent 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 air/exhaust gas
line. The condensate must be drained via a water collection tray or a floor drain posi-
tioned in an appropriate location. Supports and louvres must not be fitted. The exhaust
air/exhaust gas line must be installed in a way that ensures it is leak-tight.
See the guidelines for approving exhaust gas systems containing low-temperature exhaust
gases (issued by the German Institute for Structural Engineering in Berlin).
Exceptions
1.
Where it is not possible for evacuation to take place through a single duct, appropri-
ate measures must be put in place to ensure that, when an appliance is being oper-
ated, the exhaust gas/air mixture from the other appliances is not able to enter the
setup room (for example, baffles and merged lines with a shape that is favorable for
the flow; in this case it is important to ensure that high pressure cannot arise at the
side that is not being operated). Appliances fitted with fans must not be connected to
the same vent flue as those without fans.
2.
When installing a combined line, the exhaust air evacuation ducts for the individual
appliances must be installed horizontally in the combined line, in a way that is favor-
able for the flow. The cross-section of the vent flue must not be smaller than the
cross-section of the combined line. Combined lines must be kept as short as possi-
ble and must rise vertically up to the vent flue. A condensate drain must be placed at
the lowest point. The condensate must be drained as described above.
