SAFETY

HEALTH & SAFETY INFORMATION

The installer should be aware of his/her responsibilities under the current, local Health and Safety at Work Act. The interests of safety are best served if the boiler is installed and commissioned by a competent, qualified engineer, preferably OFTEC trained and registered. A Building Notice may be required in England and Wales and other parts of the United Kingdom.

Under the Consumer Protection Act 1987 (UK), section 6 of the Health and Safety Act 1974 (UK) and the Safety, Health and Welfare at Work Act 2005 (ROI), 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. Suitable personal protective equipment should be worn where appropriate.

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.

Safety - conformity was demonstrated by meeting the following standards:

BS EN 60335-1: 2012 + A13: 2017: Household and Similar Electrical Appliances - Safety - Part 1: General Requirements

SAFETY

Safe use of Kerosene. 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 and where necessary appropriate persona protection equipment (P.P.E.).

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.

Avoid inhaling fuel vapour as this can cause light headedness and seriously impair judgement.

THIS PRODUCT HAS BEEN DESIGNED TO THE FOLLOWING STANDARDS:

This equipment complies with the Low Voltage Directive 2014/35/EU and Directive 2014/30/EU.

EMC - conformity was demonstrated by meeting the

following standards:

and the statutory requirements of the Building Regulations.

2.1 STANDARDS & REGULATIONS - CONDENSATE DISPOSAL

Firebird condensing boilers, when in condensing mode, extract more heat from the flue products and the resulting condensate which is mildly acidic, needs to be drained from the boiler via a condensate pipe to the drainage system.

Provision must be made for the removal of condensate from the boiler to an internal soil stack, waste pipe, external soil stack, gully or soak-away, as per BS 6798: 2014.

The condensate trap is provided with the boiler and situated on the front of the boiler (under the cleaning door). This should be checked at regular intervals and cleaned during annual service.

The condensate line should:

BALANCED FLUE BOILERS

The Firebird boiler may be set for room-sealed flue operation using a Firebird condensing balanced flue kit. This kit does not draw combustion air from inside the room. It is drawn from outside, direct to the burner by an air pipe supplied with the

boiler. Flue gases are expelled through the same kit. However, if the boiler is installed in a compartment or small room, some ventilation air is necessary to maintain an acceptable temperature in the boiler area.

Balanced flue boiler in room does not require individual ventilation.

2.2 STANDARDS & REGULATIONS - FLUE REGULATIONS

Condensate Plume disPersal

When choosing the location for a condensing boiler, special consideration must be given to the positioning of the flue terminal. Care should be taken to locate it so as to prevent either the end user or their neighbours perceiving the plume to be a nuisance.

It should be noted that the normal statutory clearances required around low level flue terminals may not be sufficient to cope with plume dispersal from a condensing boiler. The following points should be considered:

1. Plumes can extend out horizontally and can also drift out to the sides and above the terminal. Care needs to be taken, therefore, to avoid the plume reaching adjacent surfaces, particularly windows and neighbours dwellings.

2. Flue terminals need to be located where air can pass freely across them to disperse vapours.

3. The effect of the moisture generated must be considered in relation to the possible corrosion of metal parts it might reach

and to the possible formation of ice on pathways in freezing conditions.

4. Keep flue terminals a minimum of 1m (horizontally) from openings in the building.

5. Do not install flue terminals directly below a window.

6. Do not install flue terminals next to a door.

7. Do not install flue terminals within 1m of ventilated soffits or eaves.

8. Keep flue terminals at least 2.5m away from a surface or boundary facing the terminal.

9. In certain circumstances the installation of a plume dispersal extension to the flue may be unavoidable. This takes the

plume exhaust from the boiler up and away from any obstruction, door or window opening and will also prevent the risk of re circulation of the plume gasses into the air intake of the burner.

Please note that only Firebird flue kits should be used for flue installations.

2112.4 STANDARDS & REGULATIONS - LIQUID FUEL SUPPLY

FUEL STORAGE TANK SITING

Consult OFTEC Manuals

It is unlikely that a fire will start at a fuel tank. However, the stored fuel must be protected from a fire or heat source that originates nearby. For this reason fuel tanks of up to 3,500 litres should be separated from openings, other than airbricks, in the building by a minimum of 1.8m and a non-fire rated boundary by a minimum of 760mm. Where this cannot be achieved, a 30 minute fire rated barrier should be constructed between the hazard and the tank, which extends a minimum of 300mm higher and 300mm past each end of the tank. Note that a minimum separation distance should be maintained between a flue exit and fire barrier (see page 7 (flue regulations)).

Steel tanks must be mounted on brick or block piers with a waterproof membrane between the piers of the tank.

Fuel storage tanks should not be sited within 1.8m of boiler flue outlets.

Do not allow household waste or hot ashes container in vicinity of oil storage tank or boiler flue outlet.

REGULATIONS & STANDARDS

Please consult all local and regional regulations, relevant to water resources (control of pollution and oil storage) as well as OFTEC Book Three.

FLEXIBLE OIL PIPE(S)

A flexible burner oil hose is supplied with the boiler which must be wholly contained within the appliance case.

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 the liquid fuel supply is completely clean and free of any dirt or foreign matter.

3.1 COMBI HE & COMBIPAC HE - HOUSEHOLDER/END USER INFORMATION

Please consult with your installer regarding the operation of your boiler. This should include

timer operation/room thermostat operation and any other additional operational features.

The basic features of the control panel are outlined below.

COMBIPAC HECOMBI HE

Maximum

Medium

Minimum

BOILER THERMOSTAT/THERMISTOR FUNCTION

The control thermostat on the boiler allows the householder to vary temperature to central heating from a low of 60˚C to 80˚C, depending on the model. Thermostats have a tolerance of ± 4˚C.

In accordance with EU boiler standards, your boiler is also fitted with a safety high limit thermostat, fixed at 110˚C. This system protects the boiler in the event of the control thermostat failing and keeps the boiler safe.

The safety high limit thermostat will shut the boiler off and will require the limit button to be pushed to restart the boiler. It is recommended to call a service engineer to establish the cause.

BURNER LOCKOUT

The boiler is factory fitted with a burner control box lockout safety feature which operates automatically if a fault occurs in the burner operation. Should this occur, the light on the front of the burner will illuminate.

Press the reset button a maximum of two times. If the boiler fails to light, call a service engineer who should check the following:

A. An interruption in the fuel supply (eg. empty fuel supply tank).

B. An electrical supply fault. C. A fault with the burner or its safety control system. D. The failure of a burner component. E. Worn or dirty fuel nozzle. F. Incorrect flue installation.

3133.2 COMBI HE & COMBIPAC HE - INSTALLER GUIDELINES

Please note the following important points before commencing installation.

Installation should only be carried out by a competent, qualified engineer, preferably OFTEC registered and familiar with the installation of the Firebird boilers referred to in this manual.

WARNING

The manufacturer cannot accept responsibility for any damage to persons, animals or property due to error in installation or in the burner adjustment or due to improper or unreasonable use or non-observance of the technical instruction enclosed with the burner, or due to the intervention of unqualified personnel.

POSITIONING THE BOILER

Compliance guide to part L now states that when installing a boiler on a new or existing system, the system should be cleaned, flushed and then protected with a suitable protection inhibitor.

Ensure that adequate clearance is available for making the water and flue connections.

The boiler is serviced from the front and 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.

PRESSURISED HEATING SYSTEM

The maximum operating working pressure is 2 bar when the system is at full operating temperature.

MAGNETIC FILTRATION

It is recommended at the time of installation of this boiler, to install a permanent effective magnetic filter on the return pipework after the last radiator on the central heating system. This will maintain maximum operational efficiency and protect the boiler from the damaging, long-term effects of “magnetite” (black iron sludge). It is essential that the filter is sized similar to the return pipework. The magnetic filter must be installed in accordance with the manufacturer’s instructions and serviced annually.

HARD WATER - LIMESCALE

On initial fill, where it is suspected that there is a high concentration of scale products, a suitable inhibitor must be used to protect the boiler and system. Check with local water authorities if in doubt (max. 200 ppm).

PIPEWORK

Do not obstruct flue fitting with Pipework. Connect pipework as shown below.

Sound levels must also be a consideration. Whilst Firebird condensing liquid fuel boilers are one of the quietest boilers on the market, some householders are particularly sensitive.

A suitable corrosion inhibitor must be added to the heating system.

UNDERFLOOR HEATING

The boiler should not be directly connected to underfloor heating, as a minimum return temperature of 40˚C is required (it can be used with underfloor heating with adequate temperature controls to ensure return values are as stated above).

PLASTIC PIPING

The boiler thermostat control and safety system is not designed, and must not be relied on, to protect plastic pipe from overheating. Plastic pipe must never be connected directly to the boiler and there must be at least 1 meter of copper pipe between the boiler and the first plastic connection. If you choose to use plastic pipe anywhere on your heating circuits, please consult the plastic pipe manufacturer for their instruction on how to ensure their product never overheats. Our boiler control and safety high limit thermostats are not designed to fulfil this function.

Firebird accepts no responsibility for failure of plastic piping and fittings for whatever reason.

FILLING LOOP

The diverter valve is factory set to “control heating mode” to facilitate system filling.

Connect the filling loop. Open both valves. Do not allow the unit to exceed 1 bar while filling and a maximum of 2 bar when the radiators are at full operating temperature. The automatic air vent will allow air to dispel from the boiler. To remove air from the storage tank, the manual air vent must be operated. When the system is full, turn off both valves and disconnect the filling loop.

CONNECTING LIQUID FUEL SUPPLY

Using the flexible hose provided, connect the burner to the incoming oil line which must have a remote acting fire valve. The flexible hose must be contained within the

appliance casing.

4.1 SLIMLINE COMBI - HOUSEHOLDER/END USER INFORMATION

Please consult with your installer regarding the operation of your boiler. This should include

timer operation/room thermostat operation and any other additional operational features.

The basic features of the control panel are outlined below.

BOILER THERMOSTAT/THERMISTOR FUNCTION

The control thermostat on the boiler allows the householder to vary temperature to central heating from a low of 60˚C to 80˚C, depending on the model. Thermostats have a tolerance of ± 4˚C.

The safety high limit thermostat will shut the boiler off and will require the limit button to be pushed to restart the boiler. It is recommended to call a service engineer to establish the cause.

BURNER LOCKOUT

MinimumMaximum Medium

Press the reset button a maximum of two times. If the boiler fails to light, call a service engineer who should check the following:

A. An interruption in the fuel supply (eg. empty fuel supply tank).

B. An electrical supply fault. C. A fault with the burner or its safety control system. D. The failure of a burner component. E. Worn or dirty fuel nozzle. F. Incorrect flue installation.

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. This should be done by a service engineer.

4234.2 SLIMLINE COMBI - INSTALLER GUIDELINES

Please note the following important points before commencing installation.

Installation should only be carried out by a competent, qualified engineer, preferably OFTEC registered and familiar with the installation of the Firebird boilers referred to in this manual.

WARNING

POSITIONING THE BOILER

Compliance guide to part L now states that when installing a boiler on a new or existing system, the system should be cleaned, flushed and then protected with a suitable protection inhibitor.

Ensure that adequate clearance is available for making the water and flue connections.

The boiler is serviced from the front and 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 Firebird condensing liquid fuel boilers are one of the quietest boilers on the market, some householders are particularly sensitive.

A suitable corrosion inhibitor must be added to the heating system.

UNDERFLOOR HEATING

PLASTIC PIPING

Firebird accepts no responsibility for failure of plastic piping and fittings for whatever reason.

PRESSURISED HEATING SYSTEM

The maximum operating working pressure is 2 bar when the system is at full operating temperature.

MAGNETIC FILTRATION

is sized similar to the return pipework. The magnetic filter must be installed in accordance with the manufacturer’s instructions and serviced annually.

COMMISSIONING

u It is the responsibility of the installer to ensure

that the boiler is properly commissioned when first used.

u The boiler should be commissioned by a

competent, qualified engineer, preferably OFTEC registered and familiar with Firebird products.

u The installation certificate and the commissioning

certificate within the Boiler Passport should be completed and posted to Firebird within 28 days of installation (this can also be done online on the Firebird website). A copy should be retained by the commissioning engineer.

u The system should be checked thoroughly.

CHECKLIST FOR INSTALLING AND

COMMISSIONING A FIREBIRD BOILER

Pre-installation check:

u Is the following documentation included with the

boiler, installation manual, boiler passport, burner manufacturer’s manual?

u Is the base on which the boiler is to be installed solid? u Allow sufficient room for future servicing of the boiler.

Boiler check:

u Baffles should be checked as they may have been

disturbed during transport.

u Check that the condensate trap is fitted securely,

primed with water and piped out into a suitable drain. It is easier to check the trap when the boiler door is removed.

u The boiler door should be refitted, complete with

graphite seal and then tightened.

Flue check:

u The flue must be fitted correctly, with a fall back to the

boiler. Note: internal fall of 2.5˚ within the flue.

u For concentric balanced flue:

- the cone supplied should be inserted in to the end

 oftheflue;

- the wall plate should be fitted with an opening

  forairundertheflue;

- check that the flue guard is fitted. u When installing a Combipac HE the 90˚ bend should

be fitted pointing up.

Please refer to burner manual for the following sections:

u Boiler set-up. u Burner settings. u Flue gas analysis and fine tuning of burner.

Where does the flue terminate:

u Make sure there is no window, door or fence within 1

metre of the flue-terminal.

u If the flue terminates in a corner or into an allyway,

re-circulation of the combustion gases in the air intake could occur. A plume dispersal may be required or an alternative flue arrangement might be available. Contact the Firebird technical department for advise.

u The appropriate class 1 flue must be used with a

conventional flue installation. Contact Firebird if unsure.

Power supply:

u Is a timed, permanent, power supply available, via a

fused spur with a 230V 50Hz mains electrical supply and a 5A fuse?

Liquid fuel supply:

u The burner is set for 28 Second Class C2 fuel. u A 15 micron oil filter should be placed in line with an

isolating valve prior to entry to the burner.

u There must be a remote sensing fire valve. u Verify that the fuel tank has been installed correctly as

per building standards.
