* If this clearance is less than 75mm the flue "knock-out" panel
sections must be removed to improve air circulation and
cooling.
Do not place clothes or objects to hinder the air circulation
required by the boiler.
Fig. 3
Conventional flue boilers require an adequate supply of fresh
air which must be delivered to the boiler for combustion
purposes through a permanent inlet, such as an air brick, into
the area where the boiler is situated.
If a cupboard or compartment which is to be used for storage or
airing is built around the boiler after installation there must be
a non-combustible partition around the boiler. Further
information can be found in BS 5410 which also describes
venting requirements.

5.2 General notes
To get the best from your boiler. please read these instructions
carefully.
5.2.1 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 boiler.
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 boiler and system. Use
of incompatible additives can cause damage and will invalidate
the boiler guarantee.
5.2.2 Condensate drain
This is a condensing boiler and the terminal will, at times give
out a plume of water vapour. This is quite normal.
The boiler also produces quantities of condensate which is
discharged regularly via a pipe to drain. This pipe must not be
blocked or altered in any way.
5.2.3 Clearances - service
Your installer will have provided adequate space around the
boiler for safety and servicing access.
Do not restrict this space with the addition of cupboards,
shelves etc. next to the boiler.

Energy saving
Greenstar Danesmoor Utility ErP – 6 720 813 330 (2014/09)
8 Energy saving
8.1 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, 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.
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 central heating 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, letter
boxes and keyholes etc. are reduced by using a suitable
draught excluder.
9 Environment/disposal
Environmental protection is a fundamental corporate strategy
of the Bosch Group.
The quality of our products, their economy and environmental
safety are all of equal importance to us and all environmental
protection legislation and regulations are strictly observed.
