When servicing the controls, label all
wires prior to disconnecting them.
Failure to do so may result in wiring
errors, which can lead to improper or
dangerous operation. Verify proper
operation after servicing.
Do not use unapproved replacement
or accessory parts.
Doing so may result in improper or
dangerous operation and will void the
manufacturer's warranty.
Do not place anything in or around
the flue terminals, such as a clothes
line, that could obstruct the air flow
in or out of the water heater.
This water heater has been approved
for use in the UK and Ireland only.
Using the water heater in any other
country will void the manufacturer's
warranty.
General Installation Guidelines
Building regulations and Benchmark
Building regulations require that installation should comply
with manufacture's instruction. It is therefore important that the
commissioning checklist is completed by the installer.
Benchmark places responsibilities on
both manufacturers and installers.
The purpose is to ensure that customers are provided with
the correct equipment for their needs, that it is installed,
commissioned and serviced in accordance with the
manufacturer's instructions by competent persons and
that it meets the requirements of the appropriate Building
Regulations. The Benchmark Checklist can be used to
demonstrate compliance with Building Regulations and
should be provided to the customer for future reference.
Installers are required to carry out installation, commissioning
and servicing work in accordance with the Benchmark Code
of Practice which is available from the Heating and Hotwater
Industry Council who manage and promote the Scheme. Visit
www.centralheating.co.uk for more information.
