,WARNING
The gas dryer is equipped for
connection to a NATURAL GAS
supply.
Installation and service must be
performed by a qualified installer,
service agency or gas supplier.
The maximum heat output is
19,500 BTU/H (5,7 kW).
In Massachusetts a licensed
plumber / gas fitter is required.
An installation kit for conversion from
NATURAL to LP gas is available as an
optional accessory.
This appliance must be installed
with its own shut off valve in the
same room. The valve must be
easily accessible to the consumer to
turn on or shut off the gas supply
after the appliance is installed.
A conversion to LP gas must only be
carried out by a Miele Authorized
Service Provider and in accordance
with all local codes and ordinances.
Minimum gas supply pressure
to obtain the required gas input is:
0.15 psi (4" WC) for natural gas
0.29 psi (8" WC) for LP gas.
During any pressure testing of the
gas system this appliance must be
disconnected from the gas supply
by closing its individual manual shut
off valve.
Maximum gas supply pressure
before the gas pressure regulator
0.37 psi (10" WC) for natural gas
0.46 psi (13" WC) for LP gas.
Any pipe connections must be made
using a thread sealant approved for
gas connections. Failure to correctly
install these items could lead to a
gas leak and subsequent explosion.
The gas installation must be made in
accordance with local codes or, in
the absence of local codes, with

Ducting
How to calculate the effective
duct length
Tips about the ductwork
– Check with your local building code
to determine the maximum allowable
duct length.
The overall duct length will determine
the duct diameter.
– Rigid metal or flexible aluminum
ducting is preferred. Flexible foil
ducting may move and bounce due
to the high airflow of the dryer. This
could lead to a thumping or grinding
noise.
^ Measure the actual duct length
needed to go from the dryer’s
exhaust connection to the vent outlet:
1. Establish the number of elbows or
bends necessary, noting the type of
bend, angle and radius involved
(see Table).
– Non-metallic flexible hose should not
be used. It is a potential fire hazard.
2. Add the additional duct length (as
derived by using the values
specified in the table) to the actual
duct length to get the effective
length.
– For best drying results avoid extra
long ducting with too many bends,
angles or tight corners.
– The shorter the exhaust ductwork,
the more efficient the dryer will be.
Expelled air is slowed down in the
ducts due to friction against the inner
walls. The shorter and smoother the
inner walls are, the less friction will
be created.
Note:
Maximum effective duct lengths:
4" (100 mm) diameter
5" (125 mm) diameter
6" (150 mm) diameter
66 ft (20 m)
131 ft (40 m)
328 ft (100 m)
– An elbow or bend creates more
friction than a straight duct. An
additional duct length factor must be
added for each elbow or bend (see
Table). This factor expresses the
resistance of the bend in terms of a
straight length of duct.
Effective duct lengths over 66 ft (20 m)
require a larger duct diameter.
Longer ducts may lead to decreases in
dryer efficiency if the next larger duct
diameter is not followed.
The additional length factor is then
added to the existing duct to give the
effective duct length.
A larger duct diameter helps to
reduce friction. Therefore duct
diameter should be increased if
longer duct lengths are required.
