INTRODUCTION
GENERAL NOTES
To get the best from your appliance please read
these instructions carefully.
SEALED HEATING SYSTEMS
If the appliance is fitted to a sealed heating
system, which is pre-pressurised, your installer
will advise you of the minimum and maximum
pressure which should be indicated on the
pressure gauge.
CLEARANCES - VENTILATED COMPARTMENT
Your installer will have provided adequate
space around the appliance for safety and
servicing access. Do not restrict this space with
the addition of cupboards, shelves etc. next to
the appliance.
+ 30mm
above elbow
Check regularly that the pressure is maintained
and contact your installer or maintenance
engineer if a permanent significant drop in
pressure is indicated on the pressure gauge. 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.
If the boiler is fitted to a sealed system
,repeated venting will reduce the quantity of
water in the system and this must be
replenished for safe and satisfactory operation
of the appliance.
200mm
*20mm from removable door or panel
**600mm service clearance required
ROOM THERMOSTAT
A room temperature controller and programmer
should be fitted to control the central heating.
Refer to the instructions supplied with the
thermostat for information on siting and setting.
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.
THERMOSTATIC RADIATOR VALVES
Only additives that are compatible with
aluminium may be used in the system. Any
incompatible additive used will invalidate the
guarantee.
CONDENSATE DRAIN
This is a condensing appliance and the terminal
will, at times give out a plume of water vapour.
This is quite normal.
It is recommended that this type of valve is
fitted to all but one of the radiators (or at least
those in the sleeping accommodation). The
remaining radiator, which must be where the
room thermostat is located, should be uncontrolled and must be left open. The
thermostatic radiator valves should conform to
the requirements of BS2767:10.
The appliance also produces quantities of
condensate which is discharged regularly, by a
siphon within the boiler, to drain.

measurements shown or more.
VENTILATION
200mm
**100mm from removable door or panel
***600mm service clearance required
This is a room sealed appliance and does not
require any air for combustion from inside the
property. 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.
Notwithstanding the requirements of BS 6798
and BS 5440 there is no need for ventilation
openings to be provided in the compartment
because of the low heat loss from the appliance
casing, if the clearances shown are maintained.
Do not operate the appliance if the flue terminal
fitted on the outside wall or roof is obstructed
or damaged.
PUMP ANTI-SEIZURE
If there has been no heating demand for 24
hours the boiler will run the system pump for a
few seconds to reduce the possibility of pump
seizure during long periods of inactivity which is
usually more frequent during the summer
months.

TIPS ON ENERGY SAVING
The boiler is designed to provide a high level of
comfort while keeping gas consumption and the
resulting environmental effect as low as
possible. The gas supply to the burner is
controlled according to the level of demand for
heat. The boiler continues to operate with a low
flame if the demand for heat reduces. The
technical term for this process is modulating
control. Modulating control reduces
temperature fluctuations and provides even
distribution of heat throughout the home. This
means that the boiler may stay on for relatively
long periods but will use less gas than an
appliance that continually switches on and off.
ENERGY
SAVING
Heating economically
Central heating systems with room
thermostats/thermostatic radiator valves
The central heating control on the boiler should
be set to the maximum rated temperature of the
central heating system.
The temperature of each room can be set
individually (except primary room with the room
thermostat) using the thermostatic radiator
valves. If you wish to have a lower temperature
in the primary room than in the other rooms,
leave the room thermostat at the set
temperature and turn down the radiator using
the radiator valve.

TIPS ON ENERGY SAVING
Roof insulation
Around 30% of the heat loss from a property is
through the roof. Replace any old insulation
with new insulation, preferably of around
200mm thickness or more.
Window frames
Single glazed windows, particularly those with
steel frames, can lose a great deal of heat.
Consideration should be given to replacement
with PVCu or wooden framed double glazed
units.
ENERGY
SAVING
Curtains
Lined curtains, or heavier full length curtains
can provide excellent insulation. However,
always ensure that the curtains do not drape
over radiators.
Draughts
Try to ensure that draughts around doors,
windows, letterboxes and keyholes etc. are
reduced by using a suitable draught excluder.
Warning - Do not block or seal any air vents
that are installed to ensure the central heating
boiler operates safely.
Room thermostats
Reducing the setting of the room thermostat by
1°C can reduce fuel consumption by up to 10%.
New control systems
Upgrade your heating control system if
necessary with the latest equipment available.
The minimum level of control is a programmer,
interlocking room thermostat and thermostatic
radiator valves.

TIPS ON ENERGY SAVING
WORCESTER BOSCH GREENSTAR 12/24Ri
8 716 106 787b (11.04)
TIPS ON ENERGY SAVING
Radiators
It is advisable to manually adjust all radiator
valves every 2-3 months to prevent them
sticking. It is also important that the plastic tops
of all valves are always in position and not
cracked or damaged to prevent accidents. Care
should be taken when vacuum cleaning carpets
to avoid damage to valves and pipework.
ENERGY
SAVING
More than often that not radiators will be sited
underneath a window, so the warm air from the
radiator heats the colder incoming air from the
window. The performance of the radiator will be
affected if the curtains are allowed to drape
over the radiator or shelves are fitted above it.
The positioning of furniture and tables in front
of the radiator should also be avoided.
The heating system and the outputs of the
radiators have been carefully selected by your
installer. The temperature obtainable in any
given room is dependent on all radiators being
operated at the same time. If you decide to turn
off radiators in unused rooms, spare bedrooms
etc., you may experience slightly lower room
temperatures in rooms adjacent to unheated
rooms.
