FOREWORD 1INTRODUCTION
This instruction manual is produced for the reference
and guidance of qualified installation engineers. EU
legislation governs the manufacture, operation and
efficiency of all domestic oil boilers. One effect of this
will be that boilers and burners will require to be
supplied as matched units tested and approved to
OFTEC Standard OFS Al00.
FIREBIRD Boilers are full manufacturing members of
OFTEC (Oil Firing Technical Association for the
Petroleum Industry) and are participating in its Boiler
testing and approvals programme to comply with OFS
A100 and EC Efficiency Directive.
Boilers must be installed, commissioned
and serviced by qualified and experienced
OFTEC approved personnel (U.K. only). It
should be noted that it is the
responsibility of the installer to ensure
that the boiler is properly commissioned.
Failure to do so may invalidate the boiler
guarantee and any extended warranty.
All appropriate OFTEC manuals and BS
Standards should be studied and their
requirements adhered to and used in
conjunction with these instructions. This
manual includes a list of some BS
Standards and Building Regulations.
OFTEC is conducting training and registration of
engineers and this is to be commended, as reading of
this manual alone for installation and servicing
procedures cannot replace the critical advantage
provided by training and years of experience.
The Firebird System Boiler Range is based on the ‘S’
Range Boilers. All boilers in the range are designed
and manufactured to meet all the latest European
standards and the thermal efficiency requirements of
the Boiler (efficiency) Regulations 1993. All Boilers
can be fitted to a conventional flue or easily adapted
to a room sealed unit by using a Firebird matched
balanced flue kit.
The control panel can be easily accessed by the
simple removal of four screws, then this assembly can
be pulled forward for access to components.
Clean combustion with kitchen-quiet operation is
assured by a highly efficient matching pressure jet
burner which produces very low NOxemissions. The
Combi Range is a dedicated sealed system boiler
having a 12 litre expansion vessel on the 50-70 and
70-90 models, on the 90-120 model there is a 14 litre
expansion vessel, system filling kit and 3 bar safety
valve all fitted within its cabinet.
A drain-off cock is fitted inside the boiler beside the
burner and there are flow and return connections
provided under top lid of the boiler for connection to
the heating and hot water systems. As all servicing can
be carried out from the front, the boiler many be
fitted under a kitchen worktop.
GUARANTEE
• All Firebird oil Boilers have a 2 year
comprehensive warranty which extends to
5 year on the boiler shell
• The Guarantee card must be fully
completed and returned to firebird within
28 day’s of installation.
• Consumable components, the nozzles and
the oil hose are excluded.
• The terms laid down on the Guarantee
must be adhered to.
NOTE: Some Firebird boilers are suitable
for conversion to gas. Conversion must only
be undertaken by Firebird approved gas
technicians using a Firebird supplied
conversion kit suitable for the particular
boiler.

Safe use of Kerosene and Gas Oil.
These fuels give off a flammable vapour when heated
moderately. Vapour ignites easily, burns intensely and
may cause explosion. The vapour can follow along at
ground level for considerable distances from open
containers and spillages collecting as an explosive
mixture in drains, cellars, etc.
Fuels remove natural oils and fats from the skin and
this may cause irritation and cracking of skin. Barrier
cream containing lanolin is highly recommended
together with good personal hygiene.
Gas oil may also cause irreversible damage to health
on prolonged or repeated skin contact.
Always store fuels in a properly constructed and
labelled tank. Always handle fuel in open air or well
ventilated space away from sources of ignition and
refrain from smoking.
Always drain fuel using a proper fuel retriever, funnel
or mechanical siphon. Never apply heat to a fuel tank,
container or pipework. Never siphon fuel through
tube by mouth. If accidentally swallowed contact
doctor immediately and do NOT induce vomiting.
Avoid inhaling fuel vapour as this can cause light
headedness and seriously impair judgement.

Under the Consumer Protection Act 1987 and
Section 6 of the Health and Safety Act 1974, we are
required to provide information on substances
hazardous to health.
INSULATION AND SEALS
Ceramic Fibre, Alumino - Silicone Fibre material are
used for boards, ropes and gaskets. Known hazards
are that people may suffer reddening and itching of
the skin. Fibre entering the eye will cause foreign
body irritation. It may also cause irritation to the
respiratory tract.
Precautions should be taken by people with a history
of skin complaints or who may be particularly
susceptible to irritation. High dust levels are only
likely to arise following harsh abrasion.
Generally, normal handling and use will not give
discomfort. Follow good hygiene practices, wash
hands before consuming food, drink or using the
toilet.
First Aid - Medical attention should be sought
following eye contact or prolonged reddening of the
skin.
The small quantities of adhesives and sealants used in
the product are cured. They present no known
hazards when used in the manner for which they are
intended.
1. Switch off all electrical and other ignition
sources.
2. Remove all contaminated clothing to safeguard
against fire risk and skin damage. Wash affected
skin throughly with soap and water and remove
clothing to a safe well ventilated area and allow
to air before cleaning.
3. Contain and smother the spill using sand or
other suitable non-combustible material.
4. Do not allow fuel to escape into drains or water
courses. If this happens, contact Fire Brigade
and Local Water Authority.
5. Consult local Authority about disposal of
contaminated soil.
If fuel is accidentally swallowed:-
* Seek medical attention immediately. Do NOT
induce vomiting.
If fuel is splashed into eyes:-
* Wash out with running water for at least ten
minutes and seek medical attention.

2-B: Operating Procedure
(All models)
To start the boiler follow this sequence:
Turn on fuel supply.
Switch power supply to boiler ‘ON’.
Remove front cover (see diagram C)
 Set the boiler thermostat to the required
temperature. The boiler thermostat controls the
boiler operation by automatically maintaining
the required boiler water temperature output.
Safe operation is also maintained by the burner
control system which provides the required ignition
and shut off sequence. If the optional timer
control is fitted this will automatically switch the
boiler off and on when heat is required.
The boiler can be turned off by any of the following means:
 Turn the timer control (if fitted) to OFF.
 Turn OFF the mains electrical supply to the boiler.
When servicing always switch off the mains supply to the boiler.
WARNING
Re: Wiring of boiler
In the situation where the primary flow from the boiler is plumbed down to connect with the heating system,
the fitting of a pump over run thermostat ( A Pipe Thermostat) is recommended.
This is fitted as standard to Firebird System Boliers.
A 4-corecable should be used in this case to supplying power to the unit. The fourth wire in the 4-core cable
can be used to bring a seperate power supply to power the circulating pump, through the over run thermostate.
This will keep the circulating pump running after the power supply controlling the boiler has been switched off,
therefore not allowing a residual heat build up in the boiler activating the safety high limit stat.

2-C: Burner Lockout
The boiler is factory fitted with a burner control box lockout safety feature
which operates automatically if a fault occurs in the burners operation.
Should this occur, the RREEDDlight on the front of the boiler control panel -
See diagram on previous page - will illuminate and its cause must be
investigated. This could be caused by:
A. An interruption in the fuel supply. (Eg. empty oil supply tank)
B. An electrical supply fault.
C. A fault with the burner or its safety control system.
D. The failure of a component. (Eg. photo cell)
EE. Worn or dirty oil nozzle.
Before attempting to restart the boiler the front panel and the burner cover
should be removed and a visual check made for any obvious problems such as
oil leaks, loose connections etc.
ENSURE OIL TANK CONTAINS CORRECT GRADE FUEL.
To restart the boiler
1. Press reset button (see diagram above)
2. Ensure that the boiler thermostat, time switch (if fitted) and any external
controls connected to the boiler are set to call for heat.
3. Check that the oil supply valves are open and that there
is sufficient oil in the tank.
4. Check that the burner lockout light is unlit and with the ‘MAINS ON’ the
boiler will be ready to commence its start sequence.
Servicing
The boiler requires servicing on an annual basis to ensure it maintains its
efficiency, continues to perform reliably and as a regular check on its
built-in safety features.
It is important that servicing should be conducted by a competent
engineer, one who is OFTEC trained and registered.

3-C: Positioning Boiler
Ensure that adequate clearance is available for making
the water and flue connections.
As the boiler is serviced from the front,
no headroom clearance is necessary but a clearance of 750mm must be
available at the front of the boiler.
No special hearth is required as the boiler is fully insulated, but the floor
must be level and capable of supporting the weight of the boiler and its
water content.
Sound levels must also be a consideration. Whilst the Firebird Combi Range
are one of the quietest boilers on the market, some householders are
particularly sensitive and the following points should be considered:
1. Tiled surfaces in a small room will amplify noise - particularly if the wall
construction is hollow.
2. If a conventional flue passes through a bedroom it is capable of
transmitting noise.
3. Low level balanced flue terminals can produce exhaust noise on the
outside terminal and this should be considered when siting near adjacent
property.
4. The Firebird low level concentric flue kit has been specifically designed
for Firebird’s indoor boilers. The use of third party low level flue kits
is not recommended and may affect its warranty.

4-A: Important Notice
Because of the improved efficiencies of boilers under E.U. Efficiency requirements and
OFT A100 Standard, it is necessary to pay extra special attention to flues and chimneys.
The improved efficiency figures achieved by modern oil boilers are attained by using
more of the heat (higher temperatures) heretofore allowed into flues and chimneys. This
previously wasted heat helped to keep bad and poorly operating and often uninsulated
flues and chimneys from condensing and causing problems. Please be fully aware of this
when replacing an existing boiler. An old and poorly operating flue may need to be
replaced to take full advantage of improved efficiencies and to avoid flue gases
condensing and appearing as white water vapour (pluming) at flue (chimney) outlet.
New flues and chimneys should be properly insulated and constructed to prevent
condensation and draughting problems. Every individual concerned with any aspect of
installation should be aware of the foregoing and should have full knowledge of and
work to European, National and Local Govt. Standards and Building
and Installation Regulations.
These manufactures instructions must not in any way be mis-interpreted as over-riding
the above or any statutory regulations. It is absolutely essential that the boiler is properly
installed so that NO FLUE GASES can enter the building at any time. Flue pipes should
be safely sealed into the wall to prevent flue gases re-entering room or building
Refer also to page 16.
PREPARING BOILER FOR CONVENTIONAL
CHIMNEY/FLUE OPERATION
Before installing boiler in the above mode please ensure:
A. That chimney flue is cleaned, draughting adequately, lined if necessary and
not subject to downdraughts. It is emphasised that boiler and flue should be
connected properly in a manner which will not allow flue gases to enter room or
building at any time from any part of the installation.
B. That adequate unrestricted air for combustion and ventilation is provided to
room in which boiler is situated - see diagram pg.20 & 21.
C. That there is no extractor fan capable of
causing negative pressure in boiler room resulting in
burner malfunction and flue gases being drawn back
into boiler room.
Conventional Flue Installations-
1. Remove blanking plate from top panel by
pulling backwards.
2. Fit trim sleeve to flue pipe (if supplied).
3. Slide upwards and ‘park’ it out of the way
4. Fit flue pipe into boiler socket and properly seal with high
temperature silicone mastic or non-cracking fire cement.
5. Fit white enamel top panel
6. Fit cut-out cover plate behind flue pipe (shown in diagram)
7. Slide trim sleeve down against top panel (If Supplied)
ENSURE UNRESTRICTED AIR-SUPPLY TO BOILER ROOM. No further
adjustments are required for adequate combustion-air supply. Check burner
operation when installation is completed, use burner Combustion Analyser
to ensure correct performance.
Consult separate burner manual supplied with boiler.

4-E Ventilation and Combustion Air
1. Conventional Flue Boilers
An adequate supply of combustion and ventilation air is essential for
efficient and safe boiler operation and the openings for this should be
positioned to cause least possible draught, with no possibility of being
accidentally blocked.
Please note: The British Standard Code of Practice for Oil Firing BS5410:
Part 1, requires a permanent air inlet opening of
550mm2per kW (above 5 kW)
of boiler rated output. (Note: 1kW = 3412 Btu/h).
Also, when the boiler is installed in a compartment or confined space,
ventilation openings are required to ventilate and to avoid overheating in
the boiler area.
FULL TEXT of both BS 5410 Part 1: 1997 and appropriate Building
Regulations for each country should be obtained and fully applied
N.B. Please Carefully Note:
A. For boiler installations in domestic garages in Scotland, Part F of

2. Balanced Flue Boilers
The Firebird boiler may be set for Room-sealed balanced flue operation using
a Firebird balanced flue kit and then does not draw combustion air from
inside the room. It is drawn from outside direct to burner by airpipe
supplied with boiler. Flue gases are expelled in the same way. However, if
the boiler is installed in a compartment or small room, some ventilation air
is necessary to maintain acceptable temperature in boiler area
4-F Domestic Heating & Hot Water Systems
HVCA Codes of Practice and BS 5449: Part 1 “Forced Circulation Hot Water
Systems” should be adhered to when installing the boiler. Refer also to
Regulations and Standards listed on page 14.
Electrical Supply
The boiler and controls require 230V 1 phase 50Hz electric supply
with a 5amp fuse.
THIS APPLIANCE MUST BE EARTHED.
A qualified electrician must carry out all electric wiring in accordance with
current I.E.E Regulations and any local regulations which may apply.
The mains electrical supply must be taken from a double pole isolating switch
with a 5amp fuse, positioned somewhere close to the boiler. Heat resisting
cable must be used which can be routed into the boiler through the access
provided on either side of the base.
Ancillary controls may be provided for with terminal connections
in the control panel.
Balanced flue boiler in room (eg. kitchen) does not require individual ventilation.

5-A Oil Storage Tank Siting
Consult OFTEC Manual
It is very unlikely that a fire should start from a domestic oil tank,
however it does need to be protected from a fire which may originate
in a building nearby. For this reason, the tank should be located at least
1.8 metres from any building and no closer than 760mm from any
boundary. If it must be closer than 1.8 metres, the building wall
should not have any openings other than ventilation openings. In addition,
the wall should have a half hour resistance to an internal fire and
extend 1.8 metres from any part of the tank.
A non-combustible radiation barrier is an alternative but this must meet the
requirements of BS 5410 Part 1: 1994, “clause 28” Section 6.4.
Steel tanks must be mounted on brick or block piers with a waterproof
membrane between the piers and tank.
Polyethylene tanks do not need pier supports and may be mounted on any
flat surface which can support the weight of the tank and its contents. They
also do not corrode and never require painting.
Oil storage tanks should not be sited close to boiler flue outlets.
Do not allow household waste or hot ashes container in vicinity of oil
storage tank or boiler flue outlet.
5-B Flexible Oil Pipe(s)
A flexible burner oil hose is supplied with the boiler.
Please note: A filter must not be fitted inside the boiler and all joints in
the oil line must be oil-tight. Soldered joints are not permissible.
Before connecting to the boiler always flush the complete oil supply
line and ensure that oil supply is completely clean and free of any dirt
or foreign matter.
5-C Single Pipe System
Where installations have the bottom of the tank above the oil burner, a
single pipe system may be used.The oil burner should then be set for single
pipe operation - See also manufacturers oil burner manual
