are those that are included with the hob
- the ones that come with the oven can
be discarded.
This cooker includes caps for all TEKA
ovens except models RT-600 and RT-800.
Caps for these two models should be
requested from the distribution outlet or the
appropriate TEKA official technical service.
Connecting the Gas
Connecting the hob to the gas mains
should be done in compliance with the
current installation standards and/or regu-
lations, and by a qualified technician (an
authorised installing engineer). The gas
connection for these hotplates should be
made with rigid piping, because the
appliance is a stationery one, where it is
destined for the EC market. The hob has a
threaded connection of 1/2’’ in diameter
(as per ISO 228-1 ) or 1/2’’ with a conical
thread (as per ISO 7-1), depending on the
regulations in the destination country.
For markets with an ISO 228-1 1/2’’ con-
nection, a 10/12 mm copper pipe is provi-
ded as an accessory for welding to the gas
intake pipe.
Ventilation slots should also be made at
the site in compliance with current norms.
Connecting the hob’s gas intake to the
mains should be done in compliance with
the basic gas installation standards for
residential premises.
TEKA assumes no responsibility for any
malfunction or damage that arises from an
incorrect or faulty installation.
In order that the hob is not damaged by
tightening the nut on the gas connection
pipe, a maximum torque of 300 cm * Kgf
should be applied.
When the gas connection has been made,
the installation should be checked to ensu-
re that it is completely sealed. If the check
is done using air, care should be taken that
the test pressure is no more than 200
g/cm² Where air is not available, soapy
water should be applied to ensure that
there are no leaks in the connections. Tes-
ting should never be done using a
flame.
When the hob has been installed, check
that the burner minimums are properly
adjusted. To do this, light the burners and
check that they do not go out if you switch
quickly from the maximum to the minimum.
Whenever the gas connection nut is remo-
ved, its washer should be changed.
Connecting the Electricity
(Only hobs with automatic ignition or elec-
tric hotplates)
Before connecting the hob to the electric
mains, check that the voltage and fre-
quency of the mains matches what is
shown on the hob’s rating plate, which is
located lower down, and on the guarantee
certificate or, where appropriate, the tech-
nical datasheet supplied, which should be
kept together with this manual.
The connection is made via an omnipolar
switch or plug where accessible, which is
suitable for the intensity to be tolerated
and which has a minimum gap of 3 mm
between its contacts, which will ensure
disconnection in case of emergency or
when cleaning the hob. It should also be
correctly earthed in line with current stan-
dards.
The connection should include correct
earthing, in compliance with current
norms.
