The dryer must be level to ensure safe  
and proper operation.  
^ Unscrew the four feet as necessary  
by turning the foot, 1, and the locking  
ring, 2, to the left.  
^ Once level, hold the foot, 1, still with  
a wrench. At the same time, turn the  
locking ring, 2, to the right using  
another wrench.  
,The dryer lid cannot be  
removed.

Installation  
,WARNING  
Before installation, disconnect the  
tumble dryer from the electrical  
supply by shutting off the power  
main or tripping the circuit breaker.  
Be sure the dryer power cord is  
unplugged from the wall.  
Do not restore power until the  
installation is complete.  
Turn the dryer’s gas shutoff valve in  
the supply line to the OFF position.  
Disconnect and discard old flexible  
gas connector and ducting material.

grounding conductor and a  
grounding plug. The dryer, when  
installed, must be electrically  
grounded in accordance with local  
codes, or in the absence of local  
codes, with the National Electrical  
Codes ANSI/NFPA 70, or the  
Canadian Electrical Code, CSA  
C22.1.  
WARNING – Improper connection of  
the equipment grounding conductor  
can result in a risk of electric shock.  
Check with a qualified electrician,  
service representative or personnel  
if you are in doubt as to whether the  
appliance is properly grounded.  
,WARNING – This dryer is  
equipped with a three-prong  
(grounding) plug for your protection  
against shock hazard and should be  
plugged directly into a properly  
grounded three-prong receptacle.  
Do not cut or remove the grounding  
terminal from this plug.  
Do not modify the plug! If it will not  
fit the outlet, have a proper outlet  
installed by a qualified electrician.

Gas connection  
Gas type  
,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  
-National Fuel Gas Code,  
ANSI Z223.1/NFPA 54 for USA  
or  
-Natural Gas and Propane  
Installation Code,  
CSA B149.1 for Canada.

Ducting  
Exhaust ducting and  
connections  
,WARNING  
A gap of 3/8" (10 mm) must be  
provided between the machine and  
the floor. This gap is necessary for  
proper air flow and must not be  
blocked by a toe-kick or thick piled  
carpets.  
Danger of toxic fumes.  
The exhaust gases from the dryer  
must only be vented outside the  
building.  
DO NOT terminate the exhaust  
ducts in a chimney, fireplace  
ducting, a combustion appliance  
vent flue, or enclosed,  
Sufficient venting of the installation  
site is essential for proper dryer  
operation. Inadequate ventilation will  
increase energy use and drying  
times.  
unventilated area such as attics,  
garages, crawlspaces, walls,  
ceilings or concealed space of a  
building.  
To reduce the risk of fire, only use  
metal ductwork.

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.

Disposal of the packing  
materials  
Disposal of an appliance  
Old appliances may contain materials  
that can be recycled. Please contact  
your local recycling authority about the  
possibility of recycling these materials.  
The packing materials protect the  
appliance during shipping. They have  
been designed to be biodegradable  
and recyclable.  
Ensure that a discarded dryer presents  
no danger to children. When being  
stored for disposal remove the door to  
the drying compartment.  
To prevent suffocation, ensure that any  
plastic wrappings, bags, etc. are  
disposed of safely and kept out of the  
reach of children.
