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 the exhaust gas/air mixture from the
machine is not able to enter the room in which the appliance is located via the ex-
haust duct for other appliances (e.g., through the use of baffles and merged lines with
a shape that is favorable for the flow). When using a shape that is favorable for the
flow, 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 evacuating the exhaust gas/air mixture through the exterior wall no dangers or
unreasonable nuisance may arise.
3. When installing a combined line, the exhaust-air ducts for the individual appliances
must be installed horizontally in the combined line, in a way that is favorable 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 possible 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.
All exceptional cases, and particularly those where a combined line is being installed, re-
quire special permission from the relevant building regulations inspector supervisor's of-
fice.

2. What needs to be observed during commissioning
Check that the points listed in section 1 ("What needs to be observed before commission-
ing") have been taken into consideration. The following should be carried out in the given
order when commissioning or converting the appliance:
1. Ask the gas supply company what the gas family, gas group, and connection pres-
sure are, and compare this information with the data specified on the tumble dryer
(see the sticker at the rear).
2. Check the factory-set jet pressure based on the tables "Settings with natural
gas"/"Settings with liquid propane" and correct it if necessary.
3. If the gas family, gas group, or connection pressure is different, it must be converted
as instructed in the section entitled "Connection and conversion instructions" and the
sticker at the rear of the tumble dryer must be replaced accordingly.
4. If the gas family needs to be changed, please request the appropriate conversion kit
from Miele Service. When doing so, please specify the product name and the appli-
ance number, as well as the gas family, gas group, gas connection pressure, and
country where the appliance has been set up.
5. Set the jet pressure at the tumble dryer's gas regulating valve (see tables "Settings
with natural gas"/"Settings with liquid propane").
