IMPORTANT
To validate the appliance warranty, it’s necessary to register
the appliance details with us. The warranty can be registered
in several ways:
by completing the warranty registration card and posting to
us using the envelope supplied
online at: vokera.co.uk
for UK residents by calling: 0870 607 0281
for ROI residents by calling: 056 6655057.
6.1 GENERAL
Once the appliance has been serviced, the benchmark Service
Record must be completed.
For UK only: It is important that the Benchmark Service Record
is correctly completed and handed to the user. Failure to install
and commission the appliance to the manufacturers instructions
will invalidate the warranty.
To ensure the continued safe and effi cient operation of the ap-
pliance, 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 component be
replaced only with a
genuine Vokèra spare part
. It should be
remembered that although certain generic components may
look similar, they will be specifi c to an individual appliance or
product range. Use of non-genuine Vokèra spare parts could
invalidate your warranty and may pose a potential safety haz-
ard. The frequency of servicing will depend upon the particular
installation conditions, but in general, once per year should be
suffi cient. 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 qualifi ed personnel. The following instruc-
tions 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.
6.2 ROUTINE ANNUAL SERVICING

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 fi nding section
will assist in determining which component is malfunctioning.
6.4 COMPONENT REMOVAL PROCEDURE
To remove a component, access to the interior of the appliance
is essential. Isolate the appliance from the electrical supply and
remove the fuse. And when necessary, close all service valves
on the appliance, remove the appliance casing as described
in section 4.7.1 and drain the water content from the appliance
via the drain valve. Ensure some water absorbent cloths are
available to catch any residual water that may drip from the
appliance or removed component. Undertake a complete com-
missioning check as detailed in section 5, after replacing any
component.
