Installation
▸Create an accurate installation cut-out.
–The mounting surface can be reamed out or created by installing wood/stone supports or using the steel angle set (see Ac-
cessories).
Access to the appliance from below via the entire cut-out area must be guaranteed. For servicing purposes, the appliance
base can be removed from below.
▸Prepare the cut-out and appliance according to the specifications in the enclosed cementing-in instructions and align the appliance
in the cut-out.
▸Fit the four adjusting braces along the circumference of the appliance to the bore holes provided and tension the appliance against
the worktop.
▸Carefully cement the appliance in and leave the silicone sealant to dry for at least 24 hours.
▸Connect to the electrical mains connection before inserting the appliance, if necessary.
Combination installation
Flush combination installation is described in document 1014381. The intermediate support kit H63789 is required for this.
Electrical connection
Electrical connections must be carried out by qualified personnel in accordance with the guidelines and standards
for low-voltage installations and the specifications of the local electricity supply companies.
A plug-in appliance may only be connected to a socket outlet with earthing contact, installed according to specifications. An
all-pole mains isolating device with 3 mm contact opening should be provided in the house wiring system. Switches, plug and
socket devices, circuit breakers and fusible cut-outs which are accessible after installation and which have all-poles switching
are permissible as isolating devices. Effective earthing and separately installed neutral and earth conductors ensure safe and
fault-free operation. After installation, live parts and cables with basic insulation must not be accessible. Check old installa-
tions.
▸Refer to the identification plate for information on the required mains voltage, current type and fuse protection.
The connection cable has either a plug or three stranded wires.
Plug-in appliances must be connected to an easily accessible power socket.
Appliances with stranded wires must be connected by a qualified electrician via a junction box according to local regulations.
Installation pipe Distribution boxClamp
The mains plug must not be cut off.
Error message U400
Incorrect connection:
Pole conductor connected to connection terminal for neutral conductor or voltage too high.
▸Quickly disconnect the appliance from the mains!

Ventilation
In order to guarantee minimum ventilation, a space of ≥20mm height is ne-
cessary beneath the appliance.
≥15
B
A
AThe rear panel of the base unit must be open around the work surface
cut-out to guarantee continuous air circulation via the ventilation slits.
The air must be drawn in from outside the cabinet and be able to circu-
late freely from inside the cabinet to the hob.
BAlternatively, a concealed fresh air supply can ensure air circulation in-
side the cabinet.
So that enough cold air can be drawn in, there must be a continuous
supply of fresh air circulating till outside the cabinet.
The air must be drawn in from outside the cabinet and be able to circu-
late freely from inside the cabinet to the hob.
Minimum distances and installation conditions
The distance from the appliance cut-out to the back wall must be ≥50mm and to the side walls ≥200mm. Parts such
as side walls and reinforcing strips which protrude into the installation space under the cooking zone must be made
of fire-resistant material.
The distance between the underside of the appliance tray and any part of the cabinet beneath that is made of com-
bustible material must be ≥20mm.
≥750
≥450
When a range hood is installed above the gas hob, the minimum distance given for
the particular range hood must be observed.
Furthermore, the minimum distances illustrated must be strictly complied with if a
lower value is stated for the range hood.
▪The worktop must be flat in order that it is sufficiently sealed against the ingress of
liquids.
▪In order to guarantee good ventilation, a space of at least 20mm in height is ne-
cessary beneath the appliance.
▸The appliances are designed for use up to a max. altitude of 2000 m above sea
level.

▸The gas connection must be positioned so that the stop-cock and the supply connection point are accessible with the appliance in-
stalled.
▸The gas connection must be positioned so that it does not get detrimentally hot during operation. In particular, the gas hose assem-
blies and the appliance’s connection fittings must be clear of hot exhaust gases (e.g. from an oven).
▸It must be ensured that the gas hose and the mains connection do not touch any hot parts of the appliance, otherwise the gas hose
and the mains cable could become damaged through heat.
▸A flexible connection lead (max. length 1.5 m) must be positioned so that it runs freely and does not come into contact with any mov-
able parts of the kitchen cabinets (e.g. a drawer).
½-inch metric thread
The gas connection on the appliance has a ½-inch external thread in accordance with ISO 228/1. If the gas installation on site already
has a corresponding counterpart, the gas appliance can be directly connected to it.
It is imperative to use the sealing ring for the front-end seal!

Thread length
The thread length of the gas connection on the appliance (external thread) So is 12mm. If the
thread length of the on-site counterpart (internal thread) Si is longer than 13mm, the front-end seal
is no longer guaranteed through the supplied green sealing ring H64006 with a height of 1.5mm.
In this case, the yellow sealing ring 1030096 with a height h of 5mm is to be used as it provides a
leak tight connection for on-site thread lengths of up to 16.5mm.
SiSo
h
½-inch conical thread
If the installation on site has a conical thread, the transition piece and sealing ring must first be
screwed onto the appliance. The transition piece has a conical external thread R ½-inch in accord-
ance with ISO 7/11. In the case of a conical screw connection, the thread makes the seal, which is
why the thread must be sealed with hemp or Teflon tape.
After the gas has been connected, leak and function testing must be carried out by a competent person.
Changes to the service menu
Changes to the service menu can only be made within 1 minute of applying the voltage. If the appliance has already been connected
for a longer period, interrupt the power supply for about 10seconds.
▸With the hob switched off, hold the and buttons depressed at the same time for 4seconds.
–An acoustic signal is emitted.
▸Hold both sliders to the left of the button depressed at the same time for 4seconds.
–An acoustic signal is emitted.
For appliance GAS411, simply press the single slider .
▸Use the button to select the next highest and the button the next lowest user setting.
–The current service menu item is shown in the timer display.
The current value under the corresponding menu item is displayed above the first active slide to the left of the button. Use the first
active slider to the left of the button to change the values. The left half of the slider functions as the minus button and the right half
