If the appliance is converted to run on a different type of gas, this
should only be carried out by a qualified gas fitter.
Gas connection
The gas hob is fitted with a gas connecting branch (1/2” external
thread).
The gas connection must be provided with a stop cock and must
be accessible. A safety gas socket is recommended. This should
be attached on the right, outside the radiation zone.
The connection can be fixed or carried out using a gas safety tube
with a socket (DIN3383, sheet 1) approved by the DVGW.
If using a safety gas tube, please make sure that it does not pass
through hot zones. The tube should be laid freely and should not
come into contact withany movable parts of the installed appliance
(e.g. drawer).
•
The gas safety tube is screwed ”gas tight” directly onto the gas
connecting branch (1/2” external thread).
•
After the hob has been connected, check the connection for
tightness.
Start of operation
Ignite all hob burners and check the burning stability of the high
and low flames. The nominal load of the high and low flames is
stated in the technical data.
Instructions for users
After the check, show the user how to operate the appliance as well
as the functions and give the user the operating instructions. Point
out in particular that changes to the construction which restrict the
combustion air supply must be followed by a new function check.
Point out to the user that any changes to the gas installation and to
the gas hob should be carried out only by qualified experts!
Converting to a different type of gas
If the appliance is converted to run on a different type of gas, the
main and bypass injectors will always have to be replaced. Screw
in the new injectors according to the gas type in the following
tables.
1. Disconnect the gas hob.
2. Remove the saucepan supports and the burner cover.
3. Using a special wrench (SW 5.5) screw the main injectors out
of the burner and screw in new injectors, (see illustration).
4. The bypass injectors (low flame) are in the burner taps and
can be replaced after removing the bottom of the appliance
with a screwdriver.
5. When placing the burner cover, please ensure that it locks into
the correct cams.
After conversion:
•
Stick the additional plate delivered with the injectors next to
the type plate.
•
Check that the gas hob is sealed.
•
Check the burning behaviour: open the gas stop cock and
ignite the burners one by one. When the gas flame is on low it
should not extinguish, not even when the control knob is
turned from high to low quickly. When the flame is on high it
should burn steadily and dully.
