BOILER OPERATION:
This boiler must only be operated by a responsible adult who has
been instructed in, understands and is aware of the boiler’s
operating conditions and effects.
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 centralheating.co.uk for more information.
HEALTH AND SAFETY
The appliance contains no asbestos and no substances have been used
in the construction process that contravene the COSHH Regulations
(Control of Substances Hazardous to Health Regulations 1988).
COMBUSTIBLE AND CORROSIVE MATERIALS:

appliance, flue or associated components and systems could invalidate
the warranty. The manufacturer accepts no liability arising from any
such actions, excluding statutory rights.
SERVICING
Advise the user to have the system serviced annually by a competent,
qualified Gas Safe registered engineer. Approved spares must be used
to help maintain the economy, safety and reliability of the appliance.
IMPORTANT
The service engineer must complete the Service Record on the
Benchmark Checklist after each service.
