INTRODUCTION
EXCELLENCE COMES AS
STANDARD
Thank you for purchasing a Greenstar oil fired condensing boiler from Worcester,
Bosch Group. The company prides itself on manufacturing boilers to the strictest
quality control standards throughout every stage of production.
Worcester, Bosch Group has led the field in innovative appliance design and
performance for more than 40 years. This heritage means all products are of
exceptional quality and proven reliability.
The condensing range in particular, is extremely energy efficient, converting more of
the fuel consumed into heat offering you economical running costs and value for
money. It sits in SEBUK band A, at the top of the energy rated appliances available.
There is also the assurance of our no-nonsense parts and labour guarantee -
backed up by an optional servicing and maintenance contract to keep your boiler
operating at peak condition and efficiency.
To find out more about Worcester, Bosch Group, use the 'Contact Information'
shown on the inside front cover.

GENERAL INFORMATION
Regularly check the pressure is maintained
and contact your installer or maintenance
engineer if there is a noticeable, permanent
drop in pressure. If the system loses
pressure it should be repressurised and the
cause of the loss investigated.
CONDENSATE:
This is a high efficiency appliance using
condensing technology which will under normal
operation produce a regular discharge of
condensate to drain and at times, give out a
plume of water vapour from the flue terminal.
ROOM THERMOSTAT:
A room thermostat must be fitted to control the
central heating. Refer to instructions supplied
with the room thermostat for information on
siting and setting.
THERMOSTATIC RADIATOR VALVES:
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 un-controlled
and must be left open.

INTRODUCTION
Read these instructions carefully to get
the best from your appliance.
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.
Vented systems:
When excessive venting or water leaks are
found in the system you must contact a
service engineer to inspect the installation
and rectify any fault.
Only use additives compatible with the
appliance and system. Use of incompatible
additives can cause damage and will
invalidate the appliance guarantee.
Frost protection:
Use a suitable anti-freeze/inhibitor at the
correct strength to protect against freezing.
A frost thermostat should be fitted to the
system if the system is exposed to low
temperatures.
Sealed heating systems:
Where the appliance is fitted to a sealed
heating system a pressure gauge should
be fitted to the system close to the
appliance. Your installer will inform you of
the minimum and maximum pressure which
must be indicated on the pressure gauge.

ENERGY
SAVING
TIPS ON ENERGY SAVING
Heating economically:
The boiler is designed to provide a high level of comfort while keeping oil
consumption and the resulting environmental effect as low as possible.
The temperature control on the boiler should be set as low as possible while still
maintaining a comfortable room temperature.
The temperature of each room can be set individually using the thermostatic radiator
valves (except the primary room with the room thermostat).
Roof insulation:
Around 30% of the heat loss from a property is through the roof. Replace any old
insulation with new insulation, preferably to a minimum thickness of 200mm.
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.
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 (or other appliance) operate 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 with the latest equipment available. The
minimum level of control for a heating system is a programmer/timer, interlocking
room thermostat and thermostatic radiator valves.

TIPS ON ENERGY SAVING
ENERGY
SAVING
TIPS ON ENERGY SAVING
Radiators:
More often than 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.
It is advisable to manually adjust all radiator valves every 2-3 months to prevent
them from sticking. It is also important that the plastic tops of all valves are always
in position and not cracked or damaged to help prevent accidents. Care should be
taken when vacuum cleaning carpets to avoid damage to valves and pipework.
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.
