Gas-Heated Tumble Dryers - Miele PDR 914 Operating And Installation Instructions

If existing vent ducting is due to be used, it must be checked before being connected to
the tumble dryer.

There is a risk of suffocation and poisoning due to exhaust gases being sucked back if
gas-powered flow heaters, gas-powered room heaters, coal-burning stoves with a flue
connection, etc., are installed in the same room, in the same flat or in neighbouring rooms
and the negative pressure is 4 Pa or more.
The following measures for suitable room ventilation (examples) can help to prevent negat-
ive pressure in the installation area:
- Install vents that cannot be closed in the exterior walls.
- Use window switches so that the tumble dryer can only be switched on when a window
is open.
Please always seek approval from your building regulations inspector to confirm that the
appliance can be operated without risk and that negative pressure of over 4 Pa can be pre-
vented.

If multiple tumble dryers are to be connected to one vent ducting, a non-return flap must
be installed directly on the duct for each tumble dryer.
If this requirement is not observed, the tumble dryers may be damaged and their electrical
safety could be affected.

The plug must be easily accessible so that the tumble dryer can be disconnected from
the power supply.

If the appliance is hard wired, adequate provision must be made on site to switch off all
poles to disconnect the tumble dryer from the power supply.

Do not block the gap between the bottom of the tumble dryer and the floor with plinth
facings, deep pile carpet etc.

Ensure that no closeable door, sliding door or an oppositely hinged door is installed that
would hinder the drum door being opened in any way.

If the mains connection cable is faulty it must always be replaced by a Miele authorised
technician to protect the user from danger.


In the event of a fault or when carrying out cleaning and maintenance, the manual gas
shut-off valve and the shut-off device on the gas meter must be closed.

Before completing commissioning, maintenance, conversion and repair work, all gas-
conducting components – from the manual shut-off valve to the burner jet – must be
checked for leaks. Particular attention must be paid to the measurement connections on
the gas valve and on the burner. Checks must be performed when the burner is both
switched on and switched off.

It is recommended that the product and its installation is annually inspected and tested
by a suitably qualified technician in conjunction with local and national regulations.
Take these safety precautions if you smell gas
- Extinguish all flames immediately.
