6.1 GENERAL
To ensure the continued safe and efficient operation of the
appliance, it is recommended that it is checked and serviced
at regular intervals. To ensure correct and safe operation of
the appliance, it is essential that any worn or failed compo-
nent be replaced only with a
genuine Vokèra spare part
. It
should be remembered that although certain generic
components may look similar, they will be specific to an
individual appliance or product range. Use of non-genuine
Vokèra spare parts could invalidate your warranty and may
pose a potential safety hazard. The frequency of servicing will
depend upon the particular installation conditions, but in
general, once per year should be sufficient. It is the law that
any servicing work is carried out by competent person such
as a Vokèra engineer, an approved service agent, British Gas,
GAS SAFE registered personnel or other suitably qualified
personnel. The following instructions apply to the appliance
and its controls, but it should be remembered that the central
heating and the domestic hot water systems would also require
attention from time to time.

6.3 REPLACEMENT OF COMPONENTS
Although it is anticipated that this appliance will give years of
reliable, trouble free service, the life span of components will
be determined by factors such as operating conditions and
usage. Should the appliance develop a fault, the fault finding
section will assist in determining which component is
malfunctioning.
