Installation and connection
When using your gas appliance
follow basic safety precautions in-
cluding the following:
Read all instructions before using
for the first time.
Be certain your appliance is prop-
erly installed and grounded by a
qualified technician.
To guarantee the electrical safety
of this appliance, continuity must
exist between the appliance and an ef-
fective grounding system. It is impera-
tive that this basic safety requirement
be met. If there is any doubt, have the
electrical system of the house checked
by a qualified electrician. The manufac-
turer cannot be held responsible for
damages caused by the lack, or inade-
quacy of, an effective grounding sys-
tem.
Do not connect the appliance to
the main electrical supply using an
extension cord. Extension cords do not
meet the safety requirements of this ap-
pliance.
Before servicing, turn off the gas
valve and disconnect the power
supply by either removing the fuse, un-
plugging the unit or manually “tripping”
the circuit breaker.
This equipment has not been de-
signed for maritime use or for use
in mobile installations such as aircraft
or recreational vehicles. However, un-
der certain circumstances it may be
possible for an installation in these ap-
plications. Please contact the nearest
Miele Dealer or the Miele Technical Ser-
vice Department with specific require-
ments.
After connecting the appliance test
for leaks according to the installa-
tion instructions.
If there is any doubt concerning in-
stallation contact Miele’s Technical
Service Department.

Correct usage
Do not operate the cooktop until it
is properly installed in the
countertop.
This appliance is intended for resi-
dential cooking only.
Use the appliance only for its in-
tended purpose. The manufacturer
cannot be held responsible for dam-
ages caused by improper use of the
cooktop.
To prevent fires, ensure that cur-
tains or any other window covering
do not blow over or near the burners.
For safety reasons never use the
cooktop to warm or heat the room.
Install the cooktop in a room that
has sufficient ventilation.
This appliance must not be set up
or operated outdoors.
Do not use aluminium foil to line
any part of the cooktop.
For proper lighting and perfor-
mance of the burners, keep the
ignitors clean and dry.
Make sure all the components of
the gas burners are assembled
correctly before using the cooktop.
Ensure that any burners in use are
always covered with a pan.
Do not use pans that extend past
the burner grate. Using larger pans
may cause the flames to spread out
and damage the surrounding
countertop or other countertop appli-
ances. The proper pansize will also im-
prove efficiency.
For safety and stability, do not use
pans with a bottom diameter
smaller than the burner grate.
Do not store aerosols, gasoline,
combustibles or any other flamma-
ble materials underneath or adjacent to
the cooktop.
Only certain types of glass/ce-
ramic, earthware, or other glazed
cookware are suitable for use on a
cooktop without breaking due to a sud-
den temperature change.
IMPORTANT SAFETY INSTRUCTIONS
5

Protection from damage
Do not use a steam cleaner to
clean the appliance. Steam could
penetrate electrical components and
cause a short circuit.
Spills containing salt or sugar
should be removed immediately, to
prevent stains.
In areas subject to infestation by
cockroaches or other vermin, keep
the appliance and its surroundings
clean at all times. Any damage caused
by pests will not be covered under war-
ranty.
IMPORTANT SAFETY INSTRUCTIONS
6

Personal safety
The burners become very hot
when in use. Make sure that no one
comes in contact with the burners.
Children should not be left alone or
unattended in an area where the
appliance is in use. They should never
be allowed to sit or stand on any part of
the appliance.
Do not store toys or items of inter-
est to children in cabinets above or
behind the cooktop. Children climbing
onto the cooktop to reach these items
may become seriously injured.
Do not allow children to operate or
play with the cooktop. Keep all
pans out of the reach of children.
Use only dry, heat resistant pot-
holders. Moist or damp potholders
used on hot surfaces can result in
steam burns. Do not let the potholder
touch the hot burners. Do not use tow-
els or other bulky items near the appli-
ance.
Wear proper apparel. Loose fitting
or hanging garments should never
be worn while using the appliance.
Do not heat unopened food con-
tainers. Build-up pressure may
cause the container to burst and result
in injury.
Do not store items on the cooktop
when not in use.
Do not let cooking grease or other
flammable materials accumulate
on the appliance.
Do not leave the cooktop unat-
tended while in use. Boil-overs
cause smoking, and greasy spill-overs
may ignite.
Do not use water on grease fires.
Smother any fire or flame, or use a
dry chemical or foam-type extinguisher.
Do not flambé under an exhaust
hood. Flames could be drawn up
into the hood by the suction or the
grease filters may ignite.
Take care that drafts like those from
fans or forced air vents do not blow
flammable material toward the flames
or push the flames so that they extend
beyond the edges of the pan.
For safety reasons the flame
should be adjusted to be the same
size as the bottom of the pan or smaller.
Do not use small pans with high flame
settings as the flames can lick up the
sides of the pan.
Only use cooking utensils suitable
for cooktop use.
Always position handles of utensils
inward so they do not extend over
adjacent work areas, burners or the
edge of the cooktop.
If there is a drawer directly under-
neath the appliance without any
wooden base in between, ensure that
no aerosols, combustible liquids or
other easily flammable materials are
kept in it. If cutlery inserts are to be
placed in the drawer, these must be
made of heat-resistant material.
IMPORTANT SAFETY INSTRUCTIONS

Cleaning and heating for the
first time
This appliance must be cleaned before
using for the first time.
^Wash the gas burner assembly in a
mild solution of water and liquid dish
soap. Wipe dry and reassemble them
in the proper order (see the "Cleaning
and care" section).
^Wipe the cooktop with a damp cloth
and dry thoroughly.
Metal components have a protective
coating which may give off a slight odor
the first time your new appliance is
heated.
The smell and any vapors will dissipate
after a short time and do not indicate a
faulty connection or appliance defect.
Before using for the first time
12

Fast-Ignition-System
The gas cooktops are equipped with a
Fast-Ignition-System incorporating the
following features:
–The control knob can be released im-
mediately after ignition of the flame.
–If the flame goes out during use, e.g.
from a draft, the burner will automati-
cally be relight.
If reignition is repeatedly unsuccess-
ful, the gas supply will be automati-
cally cut (see "Safety cut-out fea-
ture").
Turning on and off, Regulating
The control knob is used to light the
burner and to regulate the strength of
the flame.

Turning on:
^To light a burner press down and turn
the corresponding control knob coun-
ter-clockwise to the largest flame
symbol. The ignitor will click and ig-
nite the gas. Release the knob.
The ignition process lasts max. 4 sec-
onds. The flame should light within this
time. If the burner does not light, repeat
the process.
If the burner does not light at the sec-
ond attempt, turn the control knob to "ß"
and see chapter "Problem solving
guide".
^Now you can adjust the knob to the
desired setting.
Regulating the wok burner
The inner and outer burners are both
controlled by one control knob. There is
a stop at the 6 o’clock position that re-
quires you to press the knob down
while turning it in order to get from the
high flame to the low flame zone.
^To reduce the flames from a high to
low setting, turn the control knob
counter-clockwise until you reach the
stop. Press the knob down to pass
the stop, then release the pressure
and set the cooktop to the desired
setting.
^To increase the flames from a low to
high setting, turn the control knob
clockwise until you reach the stop.
Press the knob down to pass the
stop, then release the pressure and
set the cooktop to the desired set-
ting.
Since the outer portion of the flame is
much hotter than the center, the flame
should be set so that it does not spread
beyond the sides of the pan. Flame tips
which extend beyond the sides of the
pan are hazardous.
Turning off:
^Turn the control knob clockwise to
"ß".
This stops the flow of gas and turns off
the cooktop.
Do not turn the knob clockwise past
the symbol "ß" or force it past the
stop at the 6 o’clock position. Doing
so may damage the regulator.
Using the cooktop
14

Pans
Pan size
–Set the cooktop to a high flame when
using a large diameter pan and low
flame when using small diameter
pans.
–Generally, wide / shallow pans will
heat up quicker and cook more
evenly than narrow / tall ones.
– Using oversized pans may cause the
flames to spread out and damage
the surrounding countertop or other
countertop appliances.
– Do not use small pans with high
flame settings as the flame can lick
up the sides of the pan.
–Pots with a smaller diameter than the
pan support and pots that do not sit
securely (without wobbling) are haz-
ardous and should not be used.
Suitable pans
Wok burners:
You can use a wok on the special wok
burners with out any additional rings,
trivets etc.
Any heat resistant pan can be used on
a gas burner.
Unlike pans used on an electric
cooktop, the bases do not need to be
even for good results.
Thick pan bases will give more even re-
sults, as hot spots are reduced due to
better heat distribution.
Thin pan bases will conduct the heat
faster but not as evenly as thick pan
bases. Stir the food frequently to pre-
vent burning.
Using the cooktop
15

Safety cut-out feature
This appliance is equipped with an igni-
tion safety control. This control cuts the
gas supply if the flame goes out and
re-ignition is unsuccessful.
^To re-ignite the burner, turn the con-
trol knob to "ß", then follow the proce-
dure outlined in "Turning on and off,
Regulating".
The safety cut-out feature is not oper-
ated by electricity, it will be active if the
appliance is in use during a power fail-
ure.
Using the cooktop during a
power failure
The automatic re-ignition does not work
during a power failure, but you can light
the flame manually.
^Press down and turn the desired con-
trol knob counter-clockwise to the
largest flame symbol.
^While holding down the knob, light
the gas at the burner with a match.
^When the flame appears, keep the
control knob pressed in for about
8-10 seconds to allow for the ignition
safety control to reach operating tem-
perature.
Using the cooktop
16

Under no circumstances use a
steam cleaner to clean this cooktop.
Pressurized steam could cause per-
manent damage to the surface and
to components for which the manu-
facturer cannot accept responsibility.
Do not use any sharp or pointed ob-
jects which could damage the seal
between the frame and the
countertop.
Never use scouring agents, pads,
abrasive cleaning agents, or strong
cleaners e.g. oven sprays, stain or
rust removers, as these could dam-
age the surface of the appliance.
Keep the ignitor in the burner dry. If
it gets wet it will not spark.
Dry your cooktop thoroughly after
cleaning it to prevent lime deposits.
Grates
Let the appliance cool down to a safe
temperature before removing the grate.
Clean the grate, cooktop and knobs
with a sponge and a mild solution of
warm water and liquid dish soap. Soak
baked or hardened spills.
Dry the cooktop and grate thoroughly
after cleaning.
Stainless steel
Stainless steel surfaces can be cleaned
using a non-abrasive stainless steel
cleaner.
To help prevent resoiling, a conditioner
for stainless steel can also be used.
Apply sparingly with even pressure.
Stainless steel colored knobs
These controls may become discol-
ored or damaged if not cleaned reg-
ularly.
Do not use a stainless steel cleaner
on the knobs or knobs.
Spills containing salt or sugar should
be removed immediately to prevent
stains.
