INTRODUCTION
EXCELLENCE COMES AS
STANDARD
Thank you for purchasing a Greenstar Camray 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
2. Connect the flexible hose across the two
valves, one leading from the boiler and the other
from the mains supply. The connecting nuts need
only to be hand tight.
3. Slowly open both valves ensuring that water
does not leak from either end of the flexible
hose.
4. You will start to hear water passing across the
hose and valves and the grey needle on the
pressure guage will rise.
5. When the needle rises between 1 and 1.5 bar
close both valves, the needle should now remain
fixed.
6. The hose should then be disconnected from
at least one valve, a small amount of water will
emit from the hose, this is normal. If water
continues to issue from the hose the valve has
not been fully closed or is passing. If it is
passing you will need to contact your installer to
resolve the problem.
A filling loop is a set of manually operated valves
and a flexible pipe that allow water to be added
to the system when the valves are opened. This
device must be WRAS approved. To comply with
local water authority by-laws the flexible pipe
should only be connected when topping up the
system and disconnected when not in use.
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 in sealed
systems will reduce the quantity of water in the
system and this must be replenished for safe
and satisfactory operation of the appliance.
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.
Sealed heating systems:
Where the appliance is fitted to a sealed heating
system your installer will inform you of the
minimum and maximum pressure which must be
indicated on the pressure gauge.
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.
FILLING LOOP: Sealed systems only
Should the sealed system pressure within your
system have dropped to below 0.5 bar (shown
on the pressure gauge) you will need to increase
this to ensure your boiler continues to run
without problems.
Your installer should have informed you where
to find the filling system and instructed you in
its use.
Should this have been overlooked you can
increase the pressure by following these
instructions:
1. The boilers integral pressure gauge should be
visible from the filling link.

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) operates
safely.

TIPS ON ENERGY SAVING
ENERGY
SAVING
TIPS ON ENERGY SAVING
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.
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.
