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 Combi 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 ther 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.
The burner is factory set for use with kerosene 28
second class C fuel. However, 35 second gas oil
may be used on a conventional flue installation,
a oil pre-heater may be necessary.
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.

3-A Boiler Controls
Visible on the front boiler casing are
•Central Heating thermostat control.
•Time control - Domestic Hot Water. & Central Heating (optional).
•Limit-stat reset button (see diagram on page 11).
• Pressure Gauge
Also indicator lights. These are:
•Mains ‘on’.
•Burner lockout.
• Domestic Hot Water
• Central Heating
3-B Operating Procedure
To start the boiler follow this sequence:
■Turn on fuel supply.
■Switch on power supply to boiler.
■ Set the boiler thermostat to the required temperature.
■ Set timer - Domestic Hot Water & Central Heating.
The central heating thermostat controls the boiler when in central
heating mode only, thus maintaining the required boiler water
temperature output for central heating.
Domestic hot water temperature is controlled by separate non
adjustable thermostat, plus thermostatic mixing valve. See page 15.
Safe operation is also maintained by the burner control system which
provides the required ignition and shut off sequence.
If the optional timer controls are fitted this will automatically
switch the boiler off and on when cental heating and Domestic
Hot Water is required.
The boiler can be turned off by any of the following means:
■ Turn both timer switches to OFF.
■ Turn OFF the mains electrical supply to the boiler.
WHEN SERVICING ALWAYS SWITCH OFF THE MAINS SUPPLY TO
THE BOILER

3-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 RED light 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)
E. 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.
Please note: As a pre-heater kit maybe required to be fitted to the burner when
using 35-second gas oil (only allowed on conventional flue applications) this
means that annual servicing is usually sufficient - although more regular
servicing may be required depending on use.
To reset when Lock-out
light shows:
Press glowing reset button
on burner control box.

3-D Boiler Operation and Control
Boiler Operation and Control
Domestic hot water production cycle commences once the timer has been set
and switched on. If boiler and system are cold allow 20 - 30 minutes for
domestic hot water heat store to reach working temperature. Central heating
is controlled by setting the time switch - also located on this panel. The
boiler control system always gives priority to domestic hot water production
by automatically overriding the central heating mode as necessary. The
interruption to central heating lasts only as long as the demand for hot water
continues. This has no significant effect on the heating circuit. Once hot water
demand has ceased the boiler will automatically return to central heating
mode if there is a demand. When hot water only is required turn central
heating timer switch to ‘off’.
If alternative programmer is used then refer to separate programmer
instructions.
By request Combi Boilers are available with built-in timers.

Domestic Hot Water Operation
Hot water is available on demand by turning on a hot tap. This activates the
flow switch which powers the domestic hot water pump ensuring that all
boiler hot water is diverted to the domestic heat exchanger which heats the
incoming mains water to give instant mains pressure hot water.
Hot water is then mixed with mains cold water by a thermostatic mixing valve
set to ensure that it does not exceed 65°C. This is shown in accompanying
diagrams - Item No. 6.
The burner may continue to run after hot water draw off has ceased - to
ensure the pre-set temperature is restored in the heat store. This may also
occur at any time if the control system senses that there is a need to
replenish the heat store, i.e. if there has been natural temperature drop in
heat store during long periods of low demand for domestic hot water.
Programming Guide
SETTING UP
The outer dial should be set to the current time. Rotate the dial slowly
in a clockwise direction, until the correct hour is aligned with the arrow
head printed on the dial. Note that the outer dial is printed with the 24
hour clock -
8:00 a.m. = 8 on the dial. 8:00 p.m. = 20 on the dial.
Do not attempt to rotate the dial in an anti-clockwise direction.
PROGRAMMING SWITCHING TIMES
Set all tappets between the on and off times required, to the outer
edge of the dial (see figure 1). E.g. to set on at 8:00 a.m. - Off at 1:00 p.m.
push tappets between dial numbers 8 and 13 to outer edge of dial. Set any
other required switching times in a similar manner.
MANUAL SWITCH
Manual switch operation: The manual switch will provide Fixed On / Fixed
Off / Auto control, thereby allowing manual control of the switched output
without disrupting the timed (tappet) settings. Please refer to the illustration
above.
The slide switch can be set in one of the three positions available ‘on’ and ‘off’
are fixed selections - the timer will remain in the on or off condition until you
next use the manual switch to change the setting. ‘auto’ is the normal posi-
tion for the switch, allowing control to be governed by the tappet settings -
in accordance with ‘programming switching times’ above

In addition, the work must comply with OFTEC Installation
Requirements for oil fired boilers and oil storage tanks.
The installer should also be aware of his/her responsibilities under The
Health and Safety at Work Act. The interests of safety are best served if the
boiler is installed and commissioned by a competent engineer, OFTEC
trained and Registered or trained to other recognised standards.
It is the responsibility of installer and everyone concerned with any aspect
of installation to ensure that all applicable standards and regulations are
fully adhered to.
OFTEC also publish excellent guides including:-
- Safe Working Practices for Oil Firing Technicians'
- OFTEC Technical Book Three (Installation requirements for Oil Fired
Boilers and Oil Storage Tanks)
- OFTEC Technical Book Four (Domestic Heating Systems)
and it is recommended that these should be adhered to.

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. Firebird do not recommend the use of a low level flue’s on
white cased indoor boilers.
5. 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.

IMPORTANT
Because of the improved efficiencies of boilers under E.U. Efficiency
requirements and OFS 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 23.
Conventional Brick Chimney With Liner
NOTE:
All brick chimney constructions must com-
ply with current building regulations and
BS 5410: Part 1. Insulated factory made
chimneys should comply with BS 4543.

4-D Balanced Flue Siting
Notes: 1. The terminal should be positioned to avoid combustion
products entering the building or accumulating in stagnant
pockets around buildings.
2. The terminal must be protected by a guard if it is less than 2
metres above ground level or in a position where any person
has access to it (i.e. a balcony).
3. A heat protection shield should be fitted if the terminal is less
than 850mm from a plastic or painted gutter or less than
450mm from painted eaves.
Always check for any Building Regulations amendments which may
have been issued after the publication of this manual
A. Below a gutter or
sanitary pipework.
B. Horizontal from

C. Above ground or
balcony level.
D. Below eaves or
balcony
E. From an internal
or external corner.
F. From a terminal
facing the terminal.
G. From a surface
facing the terminal.
H. Vertical from
terminals on
the same wall.
I. Horizontal from

*Where the terminal is within 1 metre of any plastic material, such material should be protected from the
effects of combustion products of fuel. There are additional general requirements in most Regulations and
Standards that the flue must be positioned so that it does not cause a nuisance and permits the dispersal of
combustion products.
NOTE: The Buildings Regulations clearances shown above are minimum allowed. Account should
also be taken of prevailing site conditions, as the above minimums may in certain circumstances
need to be increased. If in doubt contact manufacturer for advice.
