7. Maintenance
To ensure continued efficient operation of the appliance, checking and servicing the appliance at
regular intervals is recommended. The frequency of servicing depends on the individual
installation conditions and use profile, but in general, once a year should be adequate. Any
maintenance work in the appliance must be carried out by a competent person such as a
registered and competent technician. Before any service operation, turn off the gas supply at the
main gas service valve upstream. Carry out the maintenance procedure as described in the
manual.
The service partners have all necessary accessories and tools for maintenance tasks.
