The Greenstar regular and system oil-fi red condensing boiler rangeThe Greenstar Danesmoor regular and Danesmoor System
series are part of a market-leading range of high effi ciency
boilers which is good news for the environment and
excellent news for specifi ers, installers and consumers.
They are ideal for customers who are looking to minimise
fuel consumption, without sacrifi cing heating and hot
water performance.
Greenstar oil-fi red regular and system boilers offer outputs
between 12 to 70kW and are specifi cally designed for use
with either a vented or sealed system. The range includes
fl oor standing internal and external models and a wall
mounted internal appliance (WM). They are ideally suited
to our range of Greenstore hot water cylinders which allow
your customers to benefi t from mains pressure hot water,
rapid re-heat times and excellent heat retention.
Every appliance is operationally tested before it leaves
the factory as part of Worcester’s rigorous quality
control procedure. When you install a Worcester
oil-fi red boiler, you can rest assured that your customer
is receiving the best quality components and highest
levels of workmanship.
Highly effi cient condensing technology
The secondary heat exchanger of the Greenstar range
extracts more energy from the oil and, when compared with
a non-condensing boiler, can cut heating and hot water bills
by over £400 a year†. All Greenstar condensing boilers are
able to deliver this energy-saving performance by extracting
additional latent heat from the exhaust gases – a highly
effi cient use of energy which signifi cantly reduces carbon
dioxide emissions into the atmosphere.
Greenstar Danesmoor regular and Danesmoor System
condensing boilers have a seasonal effi ciency of over 90%
(SEDBUK 2009 value), effi ciently producing heat for both
your customers' heating and hot water demands. This is in
comparison to standard effi ciency boilers which achieve
around 78% effi ciency, highlighting how a Greenstar boiler
can reduce heating and hot water bills.

Given the competitive nature of the heating industry, Worcester
know that installers have an important decision to make when it
comes to selecting the best product for their customers. Many
installers are loyal to the Worcester brand and recognise the
importance of the technical support and training Worcester offers.
At Worcester, we pride ourselves on the hard work that goes on
behind the scenes to make sure you and your customers benefi t
from much more than the best in high-effi ciency boilers and
renewable technologies.
For example, within the product reliability department, every
Worcester Greenstar oil-fi red boiler is tested. The testing procedure
certifi es that every boiler has been put through its paces in the
most extreme of conditions to ensure they are robust enough to
stand up to the highest of demands and toughest of environments.
We collect information on each individual component when we
fi eld trial our appliances, whilst also systematically noting any
feedback from the service engineer who worked on the boilers.
This information, along with responses from installers, is constantly
processed to ensure all technical observations can be acted upon
as a matter of urgency. It is this commitment that ultimately
ensures that Worcester products remain the best they can be.
“ 9 out of 10 professional installers would choose
Worcester for their own home”*
Andy Rose, ACR Heating Services
Why choose Worcester oil?
Did you know?
• For testing purposes Worcester has its own formula to
replicate contaminated heating system water. This mix
contains iron dust, quartz sand, hemp fi bre and other
impurities which are commonly found in system
water samples.
• Test boilers are positioned on a shaker table for 3 hours
before being set to vibrate across a range of frequencies
to simulate 3,000 miles of worldwide transport.
• Parts in the hydraulic circuit complete 300,000 water
pressure cycles to ensure optimum performance
is achieved.
• We have received a Royal Warrant in recognition of
supplying goods to Her Majesty, the Queen, an honour
we have held since 2003.
• With over 100 people in the quality control team
on-site, Worcester has more quality control engineers
than salesmen.
• As part of the global Bosch Group, Worcester has access
to world leading resources, including a corporate research
department and access to the very latest manufacturing
and product development processes.
• Each new Worcester appliance design is ‘fi eld trialled’ for
at least 1 winter period. To benefi t from winter conditions
all year round, outside of the British winter, products are
tested overseas.
• Every boiler receives an end of line full functional test
before it leaves the factory.

In addition to our own extensive testing and research, we
also listen and respond to installers as part of our product
development programme.
As a result of such feedback, we have brought about the
following distinct features that benefi t the installer.
Easy installation
The fi rst thing that you will notice is that the new Greenstar
Danesmoor models are between 13 and 17kg lighter than
the previous Greenstar Camray.
The hydraulic connections have been optimised based
on the feedback received from our customers during the
development process. This new plumbing arrangement
allows the installer to make all the connections within the
cabinet at the back of the boiler, saving time and hassle.
Further improvements include an oil line which is run
through the cabinet, as well as an oil isolation valve which
mounts on an easy-to-access bracket on the right hand side
of the primary heat exchanger. There is also space on the
bracket for the installation of a second oil isolation valve if
you are utilizing a twin pipe system.
Finally, the new Greenstar Danesmoor boilers retain the
internal condensate trap from the previous models, which
utilises a simple condensate pipe connection. The height
of the trap removes the need for a condensate pump in
most instances.
Simple servicing
The new Greenstar Danesmoor range has increased
serviceability at its heart.
Based on installer feedback, the Greenstar Danesmoor
has been created to make servicing as simple and quick as
possible, with the new layout enabling an annual service to
take place completely from the front of the boiler.
Cleaning the primary heat exchanger is now made easy
due to the one piece primary baffl es which can be quickly
removed for cleaning via the combustion chamber door.
The baffl es have been made from a specially selected
grade of temperature-resistant stainless steel. Testing has
shown that the baffl e design should not stick allowing
hassle-free removal.
The secondary heat exchanger baffl es continue to use the
folded mesh design that has been a marked success in
previous Greenstar oil-fi red boilers.

Site preparations and guidance (internal models)
All materials used on open fl ue systems must be able to
sustain the corrosive elements present within the fl ue
gases from condensing boilers. Worcester’s Oilfi t fl exible
fl ue liner is available in a variety of lengths from 8m to 15m
and is suitable for the Greenstar range† (see installation
manual for further details or contact our Technical Support
Department). Guidance on the suitability of appropriate
materials should be sought from the fl ue manufacturer, if a
non-Worcester fl ue is to be installed. Worcester can supply
a fl exible fl ue liner suitable for CF chimney installations.
Siting of appliance
Greenstar Danesmoor regular, Danesmoor regular Utility,
Danesmoor System, Danesmoor System Utility and Utility
regular oil-fi red appliances are not suitable for external
installation unless a suffi cient enclosure is provided. The
fl oor must be fi rm and level.
The fl oor on which the boiler is to be mounted should be
capable of supporting an overall weight of approximately
140kg (Danesmoor) or 300kg (Utility regular). All models
have a hearth temperature of below 100°C removing the
need for a constructional hearth.
The appliances should be positioned on a non-combustible
solid base as near to the fl ue location point as possible.
Care should be taken to ensure that the appliance is level.
Siting of appliance (wall mounted models)
Wall mounted models are supplied with a wall mounting
frame and the primary pipework can be installed prior to
the installation of the appliance. The wall must be capable
of supporting the weight of the appliance, accessories and
water content, approximately 135kg. The appliance is not
suitable for external installation unless a suitable enclosure
is provided.
Flue system
The Greenstar Danesmoor regular, Danesmoor regular
Utility, Danesmoor System, Danesmoor System Utility and
Utility regular appliances can be connected to either a
conventional fl ue system or a multi-directional, room-sealed
balanced fl ue. In either case, the conventional fl ue adaptor
or the appropriate RS fl ue kit needs to be specifi ed. The
Greenstar Danesmoor WM is only suitable for use with a
room-sealed fl ue.

Siting of appliance
The Greenstar Danesmoor External appliances are suitable
for external installation only. Appliances should be installed
at a suitable location onto a fi xed, permanent and rigid
surface. There must be suffi cient hard-standing around
the appliance to allow for servicing. Appliances must be
installed on a fl at, level surface to ensure that condensation
does not enter the primary heat exchanger. Appliances
should not be installed where there is a potential for
excessive ground water coverage. Tarmac and wood hard-
standings are not recommended.
Flue system
For all external boilers, consideration should be given to
the location of the appliance and its fl ue outlet in relation
to windows, doors and air vents. The Greenstar Danesmoor
regular and Danesmoor System External appliances can
be connected to the Greenstar Oilfi t External fl ue system
(supplied with the Danesmoor regular External) providing
balanced fl uing options at low level, high level or vertical
outlets (see page 52).
Installation and service clearances
The minimum clearances shown below should be allowed
for installation and servicing. It is strongly recommended
that the fl ue terminal faces away from walls to reduce the
possibility of “wetting” occurring. Care should be taken to
ensure that pipework leaving the appliance and entering
the building should not be exposed. The appliance should
be sited as close to the dwelling as possible.

Installation requirements
Installation regulations
The appliance should be installed by a competent person
who is aware of the Health and Safety at Work Act. They
should take appropriate action to ensure that the regulations
are adhered to. In order to give optimum effi ciency and
trouble-free operation, the appliance must be commissioned
by a qualifi ed OFTEC engineer.
In particular, the installation of this appliance must be in
accordance with the relevant requirements of the following
British Standards and regulations in respect of the safe
installation of equipment:
The compliance with a British Standard does not, of itself,
confer immunity from legal obligations.
BS 5410: part 1 & 2: Code of Practice for Oil Fired Boilers.
BS 799: part 5: Specifi cation for Oil Storage Tanks.
BS 7593: Code of Practice for treatment of water in
domestic hot water central heating systems.
BS 5449: part 1: Specifi cation for forced circulation hot
water central heating for domestic premises.
BS 5955: part 8: Specifi cation for the installation of
thermoplastic pipes and associated fi ttings for use in

Sealed system installation
The Greenstar system oil-fi red appliances are designed for
sealed systems, incorporating a pre-plumbed expansion
vessel, pressure relief valve set to 3bar, automatic air
vent and pressure gauge. The expansion vessel fi tted to
the appliance will accommodate differing system volumes
depending on initial charge pressure and system pre-
pressurisation. Under certain circumstances the system
volume may be in excess of that catered for by the
expansion vessel provided. In this instance, an additional
vessel should be fi tted as close as possible to the return
connection of the appliance. Filling of the system can take
place from a make-up vessel, which should be fi tted with
a non-return valve above the highest point in the system.
Alternatively, and to comply with the new Water Authority
requirements, the system may be fi lled through a temporary
hose connection to the mains water supply, provided that a
double check valve assembly and test point are fi tted on the
system side of the temporary connection. Greenstar regular
boilers can be installed on a sealed system subject to an
appropriately sized expansion vessel, a 3bar pressure relief
valve and a fi lling link with pressure gauge being added.
Open vented primary systems
The feed and expansion cistern (E) must be positioned
to provide a static head (S) of at least 1 metre above the

The oil burner on the Greenstar regular and system
oil-fi red appliances is supplied with a single fl exible fuel
line from the oil pump, which is connected to the main
oil supply line (via the oil isolation valve), within the
appliance. This enables the burner to be removed without
the need for disconnection of the fuel line.
The maximum permissible head is 4 metres. If the head is
greater, then a head breaking device must be incorporated
into the oil supply line.
The oil pump’s primary job is to pressurise the oil once in
the pump and force it out of the nozzle at high pressure to
atomise the fuel, ensuring clean and effi cient combustion.
This same pump can also be converted to ‘draw’ up the
fuel line in cases where the oil tank is lower than the
appliance’s burner. This conversion should be undertaken
by the installing engineer.
All oil pumps on Worcester appliances can easily be
converted to work on a two pipe system (details of
this operation are within the Installation and Servicing
instructions which come with the appliance).
More advice on fuel lines can be sought from OFTEC Book
Three as well as Technical sheet TI/134.
De-aeration devices
A de-aeration device is a container of oil, about the size of
a pint glass, with an automatic air vent on top as well as
three connections on the bottom. It removes the need to
run a return oil pipe back to the tank from the burner as
in Fig. 11. Its function is to provide a reservoir of oil from
which the oil pump draws. It also acts to vent any air in the
oil out to the atmosphere preventing a nuisance ‘lockout’
of the burner. Not all the oil drawn is consumed and any
excess is returned to the de-aeration device meaning that
whilst the burner is fi ring, there is a continuous fl ow and
return of oil. The third connection is for the main fuel line
from the oil tank. There is usually a non-return valve located
in this connection to prevent oil draining back towards the
oil tank under gravity which can create a vacuum. When
the burner is fi ring, the whole fuel supply system is under
negative pressure, i.e. suction, therefore it is imperative
that all joints on the fuel supply system are correct. Whilst
there may be no obvious signs of an oil leak externally,
when the burner is fi ring it may be possible for air to
be drawn in through a bad joint, reducing the pump’s
capabilities, resulting in a lack of fuel to the oil pump and
a nuisance ‘lockout’. This may manifest itself as a very low
level of oil or ‘foaming’ of the oil inside the de-aeration
device whilst the burner is trying to fi re.
Most de-aeration devices are made of plastic and vent
to the atmosphere. For this reason, they must always be
located externally. Metal types do exist which do not emit
vapour. These can be located internally or externally.
Top outlet oil tanks should have the non-return valve
removed from the end of the oil feed pipe within the
tank if installed in conjunction with a de-aeration device.
Supply pipe
The oil supply pipe itself would normally be annealed
copper tube with a protective plastic coating which is easily
manipulated around bends and usually enables the fuel line
to be run in a continuous length without joints. If joints
must be used, they must be accessible, even if underground
(via an access duct) and should be of the manipulative
type. Plastic pipe specifi cally for oil lines does exist and is
acceptable but must only be used underground.
Galvanised pipe, fi ttings and soldered joints must not be
used in oil lines.

Three as well as Technical sheet TI/134.

Supply pipe sizing
The diameter of the oil supply pipe itself is determined by
the distance from the oil tank to the appliance and the head
of oil whether it be positive or negative.
Tables 1 and 2 give the required diameter of supply pipe
when cross referenced with the head. Table 3 gives the
diameter of the supply pipe when the use of a de-aeration
device is made.
Oil tanks
For further information on oil tank location, please consult
the tank supplier.
Oil fi lters
Oil fi lters must always be incorporated in the oil supply line.
One should be fi tted on the outlet from the oil tank to fi lter
deposits from within the tank or fuel, and one should be
fi tted near the appliance to fi lter deposits from within the
fuel line itself. They are supplied and fi tted by the installing
engineer and are not part of the boiler’s components. It
should be possible to service them without the need for
draining down the fuel supply line. There must be suffi cient
clearance below the fi lter to enable servicing operations
to be carried out easily. Filters must comply to OFTEC
standard OFS E104.
Fire valves
A fi re valve is an essential part of the oil supply system. It
must be supplied and fi tted by the installing engineer and
is not part of the boiler’s components. Its purpose is to cut
off the fl ow of oil outside the building in the event of fi re
within the boiler area. The valve should be located on the
fuel line at the point of entry into the building. It must be
activated by a remote sensor located over the burner. A clip
is provided within the appliance for the sensor. Fire valves
must comply with OFTEC standard OFS E101.

At the centre of this innovative design is a highly powerful
magnet that removes the magnetic debris (magnetite) that
is present in the heating system water. The central location
of the magnet ensures that magnetite is collected quickly
and retained, maximising the overall protection, a proven
technology that offers a capacity to collect up to 200g of
magnetite a year. Any non-magnetic debris is caught by the
twin-action cyclonic trap.
The Greenstar System Filter has been extensively
tested in simulated systems, proving its effectiveness
in removing iron oxide, magnetite, limescale particles,
casting sand, welding debris, non-magnetic metal fl akes,
paint particles and other system pollutants.
The Worcester Greenstar System Filter
Modern condensing boilers are precision engineered
and designed to run with a clean water heating system.
Over time, dirty system water will damage a boiler and
its components, causing failures as well as potentially
shortening the life of the overall system.

and different condensate pipework methods, please

Instruction Manual.
Important points to consider when siting a condensate
drainage pipe:
• Where a new or replacement boiler is being installed,
access to an internal “gravity discharge” point should
be one of the factors considered in determining
boiler location
• The condensate pipe must be a minimum of 22mm dia.
plastic pipe
• The condensate pipework must fall at least 52mm per
metre towards the outlet and should take the shortest
practicable route
• Ensure there are no blockages in the pipe run.
Internal connections
In order to minimise risk of freezing during prolonged cold
spells, the following methods of installing a condensate
drainage pipe should be adopted, in order of priority.
Wherever possible, the condensate drainage pipe should be
routed and terminated so that the condensate drains away
from the boiler under gravity to a suitable internal foul water
discharge point such as an internal soil and vent stack.
A suitable permanent connection to the foul waste pipe
should be used. (see fi g. 1)

Where “gravity discharge” to an internal termination is not
physically possible, or where very long internal runs would
be required to reach a suitable discharge point, condensate
should be removed using a proprietary condensate pump,
of a specifi cation recommended by the boiler or condensate
pump manufacturer.
The pump outlet pipe should discharge to a suitable
internal foul water discharge point such as an internal soil
and vent stack, internal kitchen or bathroom waste pipe,
washing machine waste pipe etc. A suitable permanent
connection to the foul waste pipe should be used.

In addition to the condensate discharge options illustrated
on these pages and in the Installation, Commissioning
and Servicing Instruction Manual, the new Worcester
CondenseSure auxiliary siphon provides an innovative
alternative for the prevention of freezing for externally run
discharge condensate (see pages 40-41 for details).
External connections
Freezing conditions
• Pipework length should be kept to a minimum and the
route should be as vertical as possible
• A Worcester CondenseSure auxiliary siphon may be
used to reduce the risk of freezing
• Where pipework is subjected to extreme cold or wind
chill, a form of weather-proof insulation should be used.
Condensate waste
• Care should be taken when siting a soak away to avoid
obstructing existing services.
If no other discharge method is possible, then the use of
an externally-run condensate drainage pipe terminating at
a suitable foul water discharge point, or purpose-designed
soak away, may be considered (see fi g. 5).
If this method is chosen, then the following measures
should be adopted:
• The external run should be kept as short as possible
and not exceed 3m
• A CondenseSure auxiliary siphon may be used to reduce
the risk of freezing
• The pipe should be run internally as far as possible
before going externally and the pipe diameter should be
increased to 32mm before it passes through the wall to
the exterior. The pipe should be insulated using suitable
waterproof and weather resistant insulation
• The external pipe should take the shortest and least
exposed route to the discharge point, and should “fall”
as steeply as possible away from the boiler, without
horizontal runs in which condensate might stand
• The use of fi ttings, elbows, etc., should be kept to a
minimum and any internal “burrs” on cut pipework
should be removed so that the internal pipe section is
as smooth as possible.
Fitting an external air break
• Refer to Fig 6. When a rainwater down pipe (which goes
directly into a sewer that carries both rain water and
foul water) is used to dispose of condensate, an air
break must be installed. It should be fi tted on the
43mm pipework, between the boiler condensate outlet
and the drainpipe. The installation should take place
outside the property to avoid fl ooding during adverse
weather conditions.
40
With temperatures as low as -20ºC being experienced
in very cold winters, practices such as externally run
condensate discharge pipework are now being questioned.
In these conditions the condensate pipe on a condensing
oil-fi red boiler can freeze. This can lead to a blocked
condensate pipe, which will cause condensate to drain
back into the boiler leading to corrosion of mild steel
components and leakage of condensate. This can result
in premature component failure, damage to property and
burner failure.
The Worcester CondenseSure auxiliary siphon has been
designed to allow a more fl exible approach to boiler siting.
Tested to extreme temperatures
The Worcester CondenseSure auxiliary siphon has been
extensively tested under simulated extreme weather
conditions, proving its effectiveness in preventing frozen
condensate at -15ºC for a sustained period of 48 hours.
CondenseSure principle of operation
Most oil-fi red condensing boilers have a trap which
releases condensate as it is formed. A typical A-rated
condensing boiler will generate up to 2 litres of
condensate an hour (dependent on output and
temperature) which is discharged as a continuous
trickle. With this frequency of discharge, the condensate
pipework is never empty of condensate, consequently
increasing the potential for freezing of the pipework in
prolonged sub-zero temperatures.
The CondenseSure siphon connects to the boiler
condensate discharge outlet and collects the condensate
into a larger volume before releasing it into the
discharge pipe.
With this expanded siphonic operation, the discharge from
the CondenseSure increases to every 15 to 20 minutes,
resulting in:
• Increased velocity and fl ow rate
• Only 3 to 4 siphonic actions per hour, meaning the
condensate pipework is empty for longer
• Signifi cantly decreased or even eliminated
freezing potential.
The Worcester CondenseSure auxiliary siphon NEW
The CondenseSure insulating jacket helps to retain the temperature of the condensate.

A universal fi tting for new and existing installations
Although developed specifi cally for Worcester Greenstar
gas- and oil-fi red boilers, the Worcester CondenseSure
can also be fi tted to any make of condensing boiler for
both new and retrofi t installations. The CondenseSure
can provide a simple solution which eliminates the need
for re-siting both the new boiler and the system pipework
when replacing an existing non-condensing appliance.
CondenseSure can easily be fi tted to an existing
condensing boiler to provide peace of mind in extreme
weather conditions.
41
FittingEase of installation
The CondenseSure has been designed for ease of
installation and is suitable for most boiler applications.
Although it can be clipped to a fl ow pipe under a wall
hung boiler, on fl oor standing boilers the CondenseSure
can be wall-mounted away from the boiler, whilst still
being connected to the condensate discharge pipe.
Additional installation considerations include:
• Keeping any external pipework as short as possible
• Minimising the number of bends and connections
• Removal of burrs after cutting any pipe
• Removal of surplus solvent from the
interior of the pipe.
There is no Part P requirement as the CondenseSure has
no working parts to break down, does not use any energy
and has no electrical connections.

the following installation parameters are met:
• The externally run pipe length does not exceed 3 metres
• There is a fall on the discharge pipe of at least 2.5 degrees
• The discharge pipe diameter is not less than 32mm
in diameter.
Whilst it is not necessary to insulate the pipework, it may
be a consideration if longer lengths or lower external

• The concentric fl ue system must be inclined at
3º (52mm per metre) from the appliance, to allow
condensate to drain back into the boiler
• A white plume of condensation will be emitted from
the terminal because the appliance operates at high

• To achieve a maximum fl ue length, one of the extension
fl ue kits will need to be cut so that the permitted
maximum fl ue length is not exceeded

The following criteria should be noted when planning
the installation:
• To achieve a maximum fl ue length, one of the extension
fl ue kits will need to be cut so that the permitted
maximum fl ue length is not exceeded
• The concentric fl ue system must be inclined at
3º (52mm per metre) from the appliance, to allow
condensate to drain back into the boiler
• Because the appliance operates at high effi ciency, a
white plume of condensation will be emitted from the
terminal. Care must be taken when selecting the fl ue
terminal position
• Note: The short fl ue extension (600mm) may be used
as an alternative to the standard 1,000mm extension
on 80/125mm fl ue installations as required up to the
maximum fl ue lengths stated (Part No. 7 716 190 097).

6. Using a plume management kit, the air intake
measurement can be reduced to 150mm providing the
fl ue exhaust outlet has a 600mm clearance. Plume kits
running horizontally must have a 10º fall back to the
boiler for proper disposal of condensate.
For details on specifi c lengths see relevant boiler
Technical & Specifi cation manual.
7. 2,500mm between air intake and facing terminal.
Note
• All measurements are the minimum clearances required
• Terminals must be positioned so as to avoid combustion
products entering the building
• Support the fl ue at approximately one metre intervals

Standard plume management system
The fl ue terminal outlet has built-in stops to limit rotation
for horizontal fl uing to allow condensate to run back into
the boiler for safe disposal. Do not attempt to force beyond
the limit stops.
All plume management sections must rise by at least
173mm per metre (10º) from the terminal to ensure that
condensate fl ows back into the boiler.

Additional bends
Adding bends to the plume management system reduces
the actual plume management length. Each bend has an
equivalent straight length and must be factored into the
overall effective length.

Open (conventional) fl ued appliances must not be installed
in a bedroom, bathroom or bedsitting room.
• The fl ue system must be in accordance with BS 5410 and
the current Building Regulations.
• The fl ue must be constructed of materials suitable for use
with condensing combustion products.
• External fl ue systems must be of the insulated type.
• Brick and masonry chimneys must be lined with a
suitable non-combustible material and properly jointed
to withstand the effects of the working temperature
(minimum rating of material 120°C) of the appliance and
any condensate which may form.
• All fl ue joints must be sealed to prevent the leakage of
condensate and combustion products.
• Ensure that joints are made so that the condensate runs
away and is not collected within the joint.
NOTE: The fl ue can be increased in size from the boiler
take off point providing the joint is correctly sealed. Never
reduce the fl ue diameter from the boiler take-off point.
• Because the fl ue operates at a lower temperature on a
condensing boiler compared to that of a conventional
appliance, the fl ue draught will be lower. Typically
the draught will be between 0.5mmwg and 4.4mmwg,
measured with the fl ue warm but the burner not fi ring.
The actual fi gure will vary depending on weather
conditions, fl ue height and position.
• The fl ue should be vertical and contain as few bends as
possible. A maximum of two 135° bends should be used.
• The fl ue outlet must be extended beyond the eaves of the
building and, where possible, above the apex.
• Fit a suitable anti down-draught terminal where down
draughts are experienced.
To convert the appliance to a conventional fl ue system the
vertical fl ue adaptor needs to be specifi ed:

Oilfit flexible flue liner
The Oilfi t fl exible fl ue liner allows installation into a position
where a standard effi ciency appliance had previously
been installed. It achieves this by enabling a Greenstar
condensing boiler to be open-fl ued up a chimney. The
continuous fl exible fl ue is installed from the roof, providing
a condensate-proof lining for the chimney.
A roof terminal, extension pieces and a fl ue adaptor are all
included within the kit.

Typical installations
Open (conventional) fl ued appliances must not be installed
in a bedroom, bathroom or bed-sitting room.
Before installation commences it must be checked that:
• The chimney is structurally sound and free of obstructions
• The chimney has been thoroughly swept to remove
deposits since it was last used.
The fl exible fl ue pipe is only suitable for lining chimneys
that conform to the Building Regulations and it should not
be used as a chimney on its own or outside a masonry or
fl ueblock chimney.
All the fl exible liner and adaptors must be within the
chimney with rigid stainless steel fl ue pipe connecting to
the boiler.
The fi rst 600mm of the stainless steel fl ue pipe off the
boiler must be vertical with no bends or restrictions.
There must be at least a 25mm clearance between the
stainless steel fl ue pipe and any combustible material.
The data label must be secured onto the chimney or
chimney hearth using the plate provided.
If it is not possible to attach the plate to the chimney,
the plate can be attached, in a visible position, next to
the electricity consumer unit.
Do not attach the data plate or label to the fl ue system.
The terminal should not be modifi ed and an extra cowl or
cover must not be fi tted. The boiler is designed so that
any rain that enters the fl ue will be directed down to the
condensate drain.
Calculating the length:
L maximum = boiler maximum minus 1m*.
(Each 45º bend has a 0.5m equivalent fl ue length)
*If the chimney has an additional offset, then L will be reduced by an extra metre.**The top 45º bend may not be required if there is sufficient room in the chimney to turn the flexible liner through 45º within the chimney. The stainless steel section must be adequately supported.

WWWWWWWWWWWWWWWWWWW
Worcester has always placed great emphasis on technical
support and training for installers and service engineers.
Advances in heating technology, including the increasing use
of renewables, make the need for training greater than ever.
To ensure the highest levels of competence and expertise
in the installation of all Worcester products, we run
intensive training courses for installers, commissioning
engineers and operatives involved with servicing and
fault-fi nding.
Courses available
Our training facilities offer a number of courses suitable
for the installer and commissioning engineers, and more
in-depth courses for the servicing and fault-fi nding engineers.
Training centres throughout the UK
To enable us to meet the growing demand for training we
have invested in additional facilities at the award-winning
training academy at our Worcester headquarters. In addition
to the original academy there is now a new 400m2 unit, 25%
of which is devoted to an open-plan domestic training area
with life-size single-storey brick buildings. These feature
working Greenskies solar thermal systems which enable
installers to get up onto the roof of the building to get
more realistic training. There are bays full of all Greenstar
appliances, so installers can really get to grips with the
importance of system design. The additional space also
contains dedicated training areas for our renewable and
future products. The training centre also runs certifi ed
domestic and commercial ACS training and assessment.
Further academies are located at West Thurrock in Essex,
Wakefi eld and Clay Cross in Derbyshire, all offering our full
suite of courses. Please phone 0330 123 0166 for more
information about a course near you. Each course is run
by specialist trainers and is superbly equipped to deliver
a combination of classroom theory and practical hands-on
experience that’s second to none.
College-linked Learning
As well as offering training at our own centres, Worcester
has established close partnerships with many colleges
around the UK, equipping them with our latest products.
Call us on 0330 123 0166 to fi nd out when we will be
running the course of your choice at a college in your area.
Mobile training
To complement our training venues across the country,
we can also bring training to you.
We have mobile vehicles fully equipped with operational
Greenstar gas-fi red boilers, dry strip-down models and even
a Greensource air to air heat pump, ensuring that quality
training in a comfortable environment can be achieved on
your doorstep!
We have a 7.5 tonne mobile oil vehicle available
throughout the country for hands-on product training
and OFTEC assessments.
Distance learning/web based learning
Worcester has produced a selection of Distance Learning
CD ROMs/DVDs which are packed with information.

Worcester’s oil manufacturing heritage stretches back to
the foundation of the company in 1962. Since then, we
have built a strong reputation for not only manufacturing
products at the highest levels of quality and reliability,
but also for training installers, commissioning engineers
and operatives.
Our oil-fi red boiler training courses are extensive, covering
areas such as dismantling a jet burner, setting oil pump
pressures, maintaining a condensate trap, the relationship
between air and oil supplies, as well as the detection
of intermittent faults. Our advanced fault-fi nding course
has been designed for installers and heating engineers
who are already knowledgeable on our range of oil-fi red
products. Our expert trainers will further increase your
experience, whilst also providing a strong understanding
of fault-fi nding techniques.
A requirement of Building Regulations 2001 - Part L
(England and Wales) and Part J (Scotland) is that every
boiler installation must be self-certifi ed by an installer
who is OFTEC registered. Worcester can offer this OFTEC
training, with a variety of courses to choose from.

To complement the above courses, Worcester also runs unvented, water treatment, Domestic ACS training and
assessment, IDHEE domestic heating design, MCS Made Easy and Green Deal courses.
Please note: to attend OFTEC courses you must have a minimum of 12 months’ experience installing/servicing oil boilers or have attended an OFTEC 50 course. For candidates with limited oil experience, our Greenstar one day oil-fi red course offers pre-OFTEC training. Consult with the trainer at the end of the session to see if you are ready to undertake OFTEC assessment. For experienced oil technicians, training is not a pre-requisite for OFTEC assessment.
