1.2 MAINTENANCE
Servicing
To ensure continual safe and efficient operation and to maintain product warranties it is a
requirement that the appliance is checked and serviced at least once per year. It is the law
that any servicing must be carried out by a competent person. Removal of the appliance
cabinet by anyone other than a competent person will automatically invalidate the
appliance warranty.

If fixtures are to be positioned close to the boiler, the following minimum clearances must be
observed: Top 150mm, Left 5mm, Right 5mm, Base 100mm, Front 305mm. Extended
clearance is required to the front for servicing.

Normal case cleaning only requires dusting with a dry cloth. To remove more stubborn marks
wipe with a damp cloth and finish with a dry cloth.
