According to the Gas Safety Ordinance of Hong Kong, any gas installation works, including the installation of appli-
ances and connection tubing, must be undertaken by registered gas installers who are registered for the appropriate
classes and are employed by registered gas contractors.
Check that the local connection conditions (gas type and gas pressure) and the appliance setting match before con-
necting the appliance.
The default values for this appliance are provided on the information plate (or on the identification plate).
This appliance is not connected to a combustion by-product outlet. It must be set up and connected according to the
applicable installation conditions. Particular attention must be paid to the relevant ventilation requirements.
If installing into a combustible material, the guidelines and standards for low-voltage installations and fire protection
must be strictly observed.
All leak tests should be done with a soapy water solution. Never use an open flame to check for leaks!
When installing a built-in gas hob on top of a stove cabinet, please check that there is provision for ventilation at the
cabinet to ensure proper operation of the gas hob.
Use approved gas tubing bearing the EMSD approval marking (such as: EMSD APPROVAL
GTXXXX) for connection to appliances.
Do not store any flammable materials, sprays or pressurized containers inside the stove cabinet.

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
The intermediate support kit H63789 is required for flush-mounted combination installation.

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.

A
≥20
AThe rear panel of the base unit must be open around the work surface
cut-out to guarantee continuous air circulation through the ventilation
slits. The air must be drawn in from outside the cabinet and be able to
circulate freely from inside the cabinet to the hob. The lower plinth
must not be hermetically sealed. This can be achieved through a
shadow gap at the plinth panel or the use of a ventilation grille.
BAlternatively, a concealed fresh air supply can ensure air circulation in-
side the cabinet. In order that enough cold air can be drawn in, there
must be a continuous circulation of fresh air that extends outside the
cabinet. The air must be drawn in from outside the cabinet and be able
to circulate freely from inside the cabinet to the hob. The lower drawer
panel should therefore not hermetically seal the cabinet.

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.

▸The gas connection must be positioned so that the gas isolation valve and the supply connection point are accessible with the appli-
ance installed.
▸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 2 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 for town gas if the connection pressure corresponds to the details on the identification
plate.
Gas type Test gas Connection pressure Remark
Hong Kong town gas G110 15 mbar No external pressure reducer is required.

Connecting the appliance
The gas connection of the appliance has a G ½” cylindrical
thread with an internal conus.
Connection can be made by:
– A flexible gas connection pipe (must not exceed 2 m in
length)
Use approved gas tubing bearing the EMSD approval marking
(such as: EMSD APPROVAL GTXXXX)
for connection to appliance.
According to the Gas Safety Ordinance (Registration of Gas
Installers and Gas Contractors) Regulations, any gas installa-
tion work including the installation of appliances and connect-
ing tubing, must be undertaken by a registered gas installer
who is registered for that appropriate class and is employed
by a registered gas contractor.
