7. Service

Whoever carries out service and maintenance on the burner must be
authorised to do so. If components need to be replaced, the replacements
must be of the same make and type and be approved by the authorities. If
the burner is to be used for a different grade of gas, a new adjustment must
be carried out. If town gas is to be used, it is also necessary to convert the
combustion assembly; in some cases the multi-block or valves and gas train
may also need to be changed to a larger type.
