What to do if trouble occurs...
[
Repairs must be carried out by a qualified service engineer!
But there are some problems that you can fix yourself. First check whether
there has been any operating error. Repairs during the guarantee period are
chargeable, if they are caused by user error or non-observance of the following
instructions.

Important!
The gas category permitted for the connection of the appliances
can differ from region to region. In case of doubt enquire at your local gas
board to find out which categories of gas come into question. Check whether
the data on the rating label are in accordance with the local connection
conditions (type of gas and gas pressure) and with the appliance setting. If
there are any discrepancies the appliance must be converted accordingly!
■
If the appliance is connected up to the gas mains, particular attention must
be paid to the relevant regulations and guidelines laid down by the
associations in the country where the appliance is being operated. In
Germany and Austria these are:
DVGW-TRGI 1986/96
Technical regulations for gas installation (Germany)
TRF 1996
Technical regulations for liquefied petroleum gas (Germany)
ÖVGW-TRGI and TRG 2 Part 1
Technical regulations (Austria)
Regulations of the local gas utilities and authorities (e.g. for fire protection)
are also to be observed.
■
The appliance should only be connected and put into operation by a
qualified gas fitter who should also be the only person to carry out any work
such as maintenance and repair or adjustment and conversion. The legally
recognised regulations and the conditions for connection laid down by the
local gas board should be observed in all details.
Work which has been improperly carried out endangers the safety of the
user!
■
This appliance should not be connected to a pipe for extracting combustion
products. It must be installed and connected in accordance with the
applicable conditions of installation. Particular attention should be paid to
sufficient ventilation measures.
■
If the connection plug should not be accessible, protect the appliance by line-
protecting switches, fuses or contactors whose contact opening has a width
of at least 3 mm.
■
When making any repair, ensure the appliance is electrically dead using the
devices above and cut off the gas supply.
■
When converting from natural gas to liquefied petroleum gas, it is always
necessary to change the main injector and the low flame injector. This also
applies if the reverse is the case. This conversion should only be carried
out by a qualified gas fitter.
■
Any conversions to different types of gas must be permanently marked on
the nameplate of the appliance.
■
No changes may be made to the appliance unless with the express approval
of the manufacturer.
