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.
▸
If the hobs are used at an altitude of over 2,000 metres, a reduced performance
must be expected.
Gas connection
The gas connection and the conversion to another gas type must be carried out by an authorized installer.

▸
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).
▸
No external pressure reducer is required if the connection pressure corresponds to the details on the identification plate.

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!
