pipe, a maximum torque of 300 Kgf * cm
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

. 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 ad-
justed. To do this, light the burners and
check that they do not go out if you switch
quickly from the maximum to the minimum.
Gas conversion
Important!
Any alteration that is to be made to the
appliance to convert it to a different
type of gas should only be carried out
by a qualified technician.
Information for Technical Assis-
tance: whenever the type of gas or the ap-
pliance’s pressure is changed, the new re-
gulation plate should be placed on top of
the old one so that the new features can
be seen after the change.
The tasks involved in conversion are:
* Replace the injectors.
* Adjust the taps’ minimums.
The injectors required for each gas type
are shown in table 1.
To replace the injectors, follow these ins-
tructions:
1 Remove the grids and upper parts of the
burner so that the injector can be seen.
2 Using a number 7 pipe spanner, remove
the injectors and replace them with the
new ones. Take care to press the injector
down firmly so that there is no leakage.
3 Replace the grid and burners that were
previously removed.
When the injectors have been changed,
this is how to adjust the minimums:
1 Take the oven or the control panel out so
that you can access the gas taps.
2 Turn the burners on to their minimum.
3 Use a slim, grooved screwdriver to turn
the screw located to the right or in the
centre of the gas tap’s shaft (the flame
increases when you turn to the left and
decreases when you turn to the right).
4 When properly adjusted, check that the
flame does not go out when you turn the
knob quickly from maximum to minimum.
TEKA INDUSTRIAL, S.A. assumes no
responsibility for any hob malfunction if the
gas conversion or the adjustment of the
burners’ minimums has not been carried
out by TEKA’s official personnel.
