BENCH MARK STANDARD
‘Benchmark’ is a code of practice for correctly
installing, commissioning and servicing of
domestic water heating appliances
A Benchmark Log Book is provided by the
manufacturer for the installer to complete ALL
details together with their CORG I registration
number and sign to confirm that the boiler has
been installed and commissioned according to
the manufacturer’s instructions
IMPORTANT: The completed Benchmark Log
Book will be required in the event of any
warranty work and may be required by the local
Building Control Inspector.
HEALTH & SAFETY
The appliance contains no asbestos and no
substances used in the construction process to
contravene the COSHH Regulations (Control
of Substances to Hazardous Health
Regulations 1988)
COMBUSTIBLE AND CORROSIVE MATERIALS
Do not store or use any combustible materials
(paper, thinners, paints etc.) inside or within the
vicinity of the appliance
Chemically aggressive substances, such as
halogenated hydrocarbons containing chlorine
or fluorine compounds can corrode the
appliance and invalidate any warranty.
FITTING & MODI FICATIONS
Fitting the appliance and any controls to the
appliance may only be carried out by a
competent engineer in accordance with the
Gas Safety (Installation and Use) Regulations.
Flue systems must not be modified in any way
other than as described in the fitting
instructions and any misuse or unauthorised
modifications to the appliance, flue or
associated components and systems could
invalidate the warranty. The manufacturer
accepts no liability arising from any such
actions. This does not effect your statutory
rights
SERVICI NG
The user is recommended to have the system
regularly serviced by a competent, qualified
engineer (such as British Gas or CORGI
registered personnel) using original spares, to
help maintain the economy, safety and reliability
of the appliance and to have the Service
Record completed in the Benchmark Log Book
The appliance should be serviced once each
year after installation unless the particular
installation conditions and usage demand more
frequent services
IMPORTANT - ensure that the service engineer
completes the Service Record in the
Benchmark Log Book after each service

To get the best from your appliance please read
these instructions carefully
SEALED HEATING SYSTEMS
The appliance is fitted to a sealed heating
system which is pressurised. Your installer will
tell you of the minimum and maximum pressure
which must be indicated on the pressure
gauge.
Check regularly that the pressure is maintained
and contact your installer or maintenance
engineer if there is a permanent significant drop
in pressure. If the system loses pressure it
should be repressurised and the cause of the
fall investigated.
CENTRAL HEATING SYSTEMS
During the first few hours of operation of the
central heating system, check that all radiators
are being heated at an even rate. If the top of a
radiator is at a lower temperature than the
bottom then it should be vented by releasing air
through the venting screw at the top of the
radiator. Ask your installer to show you how this
is done. Repeated venting will reduce the
quantity of water in the system and this must be
replenished for safe and satisfactory operation
of the appliance.
Should water leaks be found in the system or
excessive venting is required then a service
engineer must be contacted to inspect the
installation and rectify any fault.
Only additives that are compatible with
aluminium may be used in the system. Any
incompatible additive used will invalidate the
guarantee.
FLUE OUTLET
This is a condensing appliance and the terminal
will, at times give out a plume of water vapour.
This is quite normal.
CONDENSATE DRAI N
The appliance also produces quantities of
condensate which is discharged regularly by a
pump within the boiler to drain.
ROOM THERMOSTAT
A room temperature controller (eg. Worcester
TR2 room temperature controller with night
setback module) should be fitted to control the
central heating. Refer to the instructions
supplied with the thermostat for information on
siting and setting.
THER MOSTATIC RADIATOR VALVE S
It is recommended that this type of valve is
fitted to all but one of the radiators (or at least
those in the sleeping accommodations). The
remaining radiator, which must be where the
room thermostat is located, should be uncontrolled and must be left open. They should
conform to the requirements of BS2767:10.
SHOWERS, BIDETS, TAPS & MIXING VALVES
Standard hot and cold taps and mixing valves
must be suitable for operating at mains
pressure. Thermostatically controlled or
pressure equalising shower valves will guard
against the flow of water at too high a
temperature.
Hot and cold mains fed water can be supplied
directly to an over-rim flushing bidet subject to
local water company requirements.
With all mains fed systems the flow of water
from individual taps will vary with the number of
outlets operated simultaneously and the cold
water mains supply pressure to the property.
Flow balancing using “ball-o-fix” type valves is
recommended to avoid an excessive reduction
in flow to individual outlets.
For further information contact Worcester Heat
Systems Ltd. Technical Department.

HOT AND COLD FLOW
The flow of water demanded from both hot and
cold service outlets is dependent on the mains
supply, it may not be possible in some
installations to operate all outlets
simultaneously.
WATE R MAINS FAILURE
If there is a failure of the mains water supply
then no water will be available at a tap or
shower until the mains supply is restored. The
appliance will still operate in the central heating
mode.
USE IN HAR D WATER AR EAS
In exceptionally hard water areas a device to
prevent scale formation may be fitted.
Installation of a scale inhibitor assembly should
be in accordance with the requirements of the
local water company. An isolating valve should
be fitted to allow for servicing.
Alternatively the maximum temperature of the
domestic hot water may be reset to about 45°C
which will reduce the risk of scale formation in
these hard water areas.
VENTILATION
This is a room sealed appliance and does not
require any air for combustion from inside the
house. If the appliance is fitted into a cupboard
or a compartment is built around the appliance
after installation then the compartment must be
separated from the boiler space by a perforated
non-combustible partition as described in BS
6798 and BS 5440.
Notwithstanding the requirements of BS 6798,
there is no need for ventilation openings to be
provided in the compartment because of the
low heat loss from the appliance casing if
clearances on the next page are observed.
Do not operate the appliance if the flue terminal
fitted on the outside wall or roof is obstructed
or damaged.
PUMP
The pump is set by the manufacturer and must
not be adjusted.
PUMP ANTI-SEIZURE
If there has been no heating demand for 24
hours, the pump will run for a few seconds to
reduce the possibility of pump seizure, which is
possible during long periods of inactivity.
