1974.
• IRL-Safety,HealthandWelfareatWork
Act 2005, (Construction Regulations
2006).
Installation, commissioning and/or
servicing should only be carried out by a
competent person.
The small amounts of adhesives and
sealants used in the manufacture of this
appliance are cured and do not present
any known hazards when used for their
intended purpose.
NOTE: If your Firebird inset stove is not
installed, operated and maintained
properly a house fire may result!
4.3 AIR SUPPLY
It is essential that you provide an adequate
air supply for safe and efficient operation
of your inset stove. The air supply will
ensure efficient combustion. Failure to do
so could result in smoke filling into the
room or blackening of glass.
Air Requirements
A permanent air entry opening or
openings, with a total free area of at
least 550mm2per kW of rated output
above 5kW, shall be provided. Under no
circumstances should this be less than
6500mm2.
If a flue draught stabiliser is fitted, then the
first 5kW of rated output is 300mm2per kW
and the balance of the rated output is
850mm2per kW.
This appliance is capable of having the air
supply introduced through the base.
(Figure 1.) The same equation with respect
to total free area must be adhered to.
NOTE:Noextractorfanshouldbettedin
the same room as the appliance.
4.4 FIREPLACE
Whenttingintoanexistingreplace,

In addition, access to the front of the
chimney breast may be required, via a hole,
forxingtheuepipeandbacklling.
4.5 HEARTH
The appliance must be installed on a
hearth that can take the weight and is of a
non-combustiblematerial.
Ensure that when installing the appliance,
thefollowingregulationsaremet:
IRL-BuildingRegulations1997,Technical
GuidanceDocument5,statesthatthe
hearthmustextendinfrontofthe
appliance by 500mm and to the sides
by 150mm.
UK-Buildingregulationsforclass1
appliances state that the hearth must
extendinfrontoftheapplianceby
300mm and to the sides by 150mm.
4.6 CHIMNEY/FLUE
In order for the appliance to have sufficient
draw to perform satisfactorily, a height of
no less than 4.5 meters, vertically from the
top of the appliance to the top of the
chimney, is required. Alternatively,
chimney design with sufficient draught
can be calculated, in accordance with
EN13384-1.
Theexistingchimneymustbechecked
before installing the appliance (It must be
sound, free from cracks and blockages and
swept).Itshouldnothaveanexcessive
cross sectional area (greater than 250mm
x250mmsquareorequivalentarea).
Do not connect the insert stove to a
chimney flue which is connected to
another appliance.
It is essential that you use only stainless
steel pipes for your inset stove and that
all installations are carried out in
accordance with building regulations
and manufacturer’s instructions. Always fit
pipes with the narrow side down, to allow
any creosote to run down the inside of the
pipe. This avoids possible fire risk.
Firebird recommend that a thorough
inspection of the chimney is carried out
prior to installation and on a regular basis
thereafter.
The chimney should be of sound
construction, free from debris, capable of
withstandingextremelyhightemperatures
and have no evidence of cracks or other
faults.
Best installation practice is to install a flue
lining suitable for solid fuels. A rigid
connection adaptor should be used to
connect the flue liner to the insert stove.
Pipe bends should be kept to a minimum
and there should be no more than two 45˚
bends on any installation.

4.7 INSTALLING AND BACK FILLING
1. Remove the inset stove from its
packaging and inspect for any
damage.
2. Place adjustable legs to the bottom of
the inset stove if required.
3. Fit the appliance into the opening,
making sure it is central. A good seal
should be made between the flange
and the surround. The adjustable legs
can be used to level the inset stove if
required.
4. Removeanyexcessrecementfrom
around the flange.
5. Make the connections to the boiler
and ensure the primary flow pipe rises
from the boiler so that no air is
trapped in the boiler.
6. Before back filling, fill the system
with water and check the boiler
connections for leaks. Ensure that
the materials used for back filling are
non-combustible.
7. Anexpansionpipemustbettedto
the inset stove water outlet pipe,
which must be vented to atmosphere,
above the height of the header tank.
There should not be any valves
between the inset stove and the vent
pipe outlet and it must not be
possible to obstruct the outlet in
anyway.
8. Fit the flue connector to the top of the
appliance so that it is central to the
chimneyandextendstothepoint
where the chimney narrows.
Ensure that the flue manufacturer’s
instructions are adhered to at all
times.
9. All voids must be filled and the flue
pipe flaunched into the chimney,
so that no soot can collect when
sweeping the chimney.
10. Make good the holes in the front and

4.8 HEATING AND HOT
WATER SYSTEM
The central heating system must comply
with BS5449 part 1.
The hot water cylinder must be indirect
and should comply with BS1566 part 1.
The system must be open vented and the
header tank should not be more than 12
meters above the boiler.
In case of pump failure or a power cut,
the system should be able to work on
gravity to the hot water cylinder.
In addition, the fire should be quenched,
using best practice. Dumping of hot water
(i.e. running hot water taps) may be
required.
NOTE: The system should never be valved.
Depending on the size of the room into
which the appliance is fitted, a radiator in
thesameroommaygivegreaterexibility
in operating the system and ensure
sufficient heat to the room.
4.9 SYSTEM CONTROLS
The system pump may not be controlled
by time switches. The inset stove can be
controlled with pipe thermostat. Ensure
that all controls are installed to building
regulations.
Radiators can be fitted with thermostatic
ormanualvalves.Pleasenote:novalves
must be fitted to radiators where they act
as the heat leak.
4.10 CHECKS BEFORE LIGHTING
Note: Prior to lighting the inset stove,
allow sufficient time for the back fill to dry
at normal conditions.
The following checks should be carried out
priortolightingareintheinsetstove:
1. The fire grate is in place.
2. The flue is clear.
3. Ensure that baffles are in place.
4. Check the door fitting.
5. The system is full with water and
vented.
6. Has a suitable inhibitor been added?
4.11 COMMISSIONING
Light the fire and check all joints and seals.
Ensure that fumes and smoke are being
taken up the chimney and no fumes are
entering the room.
The heating system should be balanced in
accordance with best plumbing practice.
Before completing the commissioning,
the householder should be advised as to
the operation of the inset stove and the
heating controls.
The instruction manual should remain
with the householder.

10
5.0 OPERATING
INSTRUCTIONS
5.1 FUELS
HEATAS Ltd. approval covers the burning of
the following smokeless fuels in this inset
stove:
• Ancit.
• AnthraciteLargeNuts.
• Centurion.
• Cosycoke.
• Maxibrite.
• Phurnacite.
• SunbriteDoubles.
• WelshDrySteamCoal(largenuts).
• SmokelessCoal
The above fuels are all suitable for smoke
control areas.
NOTE: Petroleum coke should never be
used on this appliance. If used, it will
invalidate the guarantee.
Wood can be used in this appliance.
The two main factors to be considered
when burning wood, are the moisture
content and the density.
Moisture in wood will have an effect on
theCV(amountofheatperunitvolume),
as any moisture in the wood has to be
boiled away before the wood will burn.
It can also create smoke and tars which
could be corrosive and increase the risk
of a chimney fire.
Well-seasonedlogscanhave
approximatelytwicetheCVof
unseasoned green logs.
Hard wood logs are denser than soft wood
logs and tend to burn for a longer period
of time.
Air dried wood should be seasoned for at
least 12 months before burning.
Wood that has been contaminated or
treated with varnish, paint or other
coatings and preservatives, should not be
used.Notonlydoesitreleasenoxious
chemicals into the air, but it can also
contribute to the amount of tar and
deposits building up in your chimney.
NOTE: You should never over stock/over
fill your inset stove. The recommended
level to fill the inset stove, is up to the
metal lip, as illustrated on the picture
below.
5.2 LIGHTING AND CONTROLLING
5.2.1 WOOD
NOTE: Ensure the baffles are properly
installed prior to lighting the inset stove as
perFigure1and2onthenextpage.Carry
out all checks as per 4.10.
Place some kindling and a firelighter on
top of the grate, add some dry kindling
and two to three logs.
Metal Lip - recommended fill level.

11
Fully open out the secondary air control
(right hand side) and open the primary air
control (left hand side) to about half way.
See Figure 3.
Light the fire and close the door.
The room should be kept well ventilated
on the first lighting, as there may be an
odour and some smoke may be released.
This is just the paint reacting to the heat
and will only last for a short time.
When the fire is well lit, adjust the primary
and secondary air controls to give you the
required level of flame. See Figure 4. For
best results, wood will generally need more
secondary air than primary air.
Refuel the appliance when there is still a
good bed of glowing embers. Place the
required amount of logs on the bed, open
the secondary air control fully and close
the door.
Once the new fuel has taken, adjust the
secondary air control.
5.2.2 SMOKELESS FUEL
The same applies as with wood, but
you will require more primary air than
secondary air with smokeless fuel.
When burning Homefire or Anthracite
smokeless fuel, always have the secondary
air fully open on ignition. Leave it open for
3-5minutesandadjustthereafter.
5.3 OVERNIGHT BURNING
To achieve slow burning/overnight
burning with smokeless coal, close the
secondary air and open the primary air
slightly. Please note that slow burning may
cause the glass to blacken and cause sooty
deposits in the flue way.
Furthermore, these settings are guidelines
and are dependent on the draft and fuel
quality.
Figure 4.
Figure 3.
Figure 2.
Figure 1.

12
5.4 CLEARANCE OF ASH
The ash pan should be emptied on a
regular basis and always before it becomes
too full. See Figure 5. If ash is left to build
up close to the grate, it will cause damage
to it.
The ash pan is best emptied before you
riddle the fire, when the ash is at its
coolest. Check under the ash pan once a
week and clean this area if necessary. See
Figure 6. Ensure the bottom plate (under
the ash pan) is always replaced after
cleaning.
5.5 THROAT PLATE (BAFFLES)
5.5.1 INITIAL BURNING
In the first month after installation, the
baffles should be checked before each
ignition, to establish a burning pattern to
fuel type. This is necessary because some
fuels deposit more soot than others.
5.5.2 REGULAR CHECKING
Remove and clean any fly ash or soot that
has built up. This should be done on a
regular basis, about once a month or more
as deemed necessary.
6.0 MAINTENANCE
6.1 CLEANING
When cleaning the glass, always do so
when the inset stove is cold. Abrasive
cleaners or pads should never be used on
the glass. For stubborn deposits, use a
proprietary stove glass cleaner or ceramic
hob cleaner.
The front of the appliance may be wiped
with a damp, lint free cloth and then dried
with a dry lint free cloth. Again, make sure
the appliance is cold.
6.2 DOOR SEALS
Check that the seals are in good condition
and in the correct place. If they are worn,
they should be replaced.
6.3 WHEN NOT IN USE
In the summer months or anytime that the
inset stove is not being used for a long
period of time, clean out the inside
thoroughly and open the primary air
control slightly.
This will help to prevent condensation,
and hence corrosion.
6.4 CHIMNEY CLEANING
The chimney should be cleaned at least
once a year and this can be done through
the inset stove. Remove the throat plates
(baffles) and fire bars prior to undertaking
a chimney clean.
Figure 6.
Figure 5.

13
6.5 CHIMNEY FIRES
If the instructions in this manual are
followed and the chimney is cleaned once
a year, chimney fires should not occur.
Should the chimney go on fire, close both
air intakes and ensure the door is fully
closed. This should be enough to ensure
the chimney fire dies. If the fire continues,
then call the fire brigade. Do not open the
inset stove door at any time during this
periodasitmaycausere-ignition.Leave
the door closed until the inset stove is cold.
The chimney must be swept and carefully
examinedfordamageafterachimneyre.
6.6 FUME EMISSION
Fume emission is potentially dangerous.
There will however be the occasional
emission of fumes when opening the door
to clean out ashes or filling the fire.
Take the following actions immediately, if
yoususpectpersistentfumeemission:
1. Open all windows and doors to
ventilate the room.
2. Let the fire go out.
3. Call professional help to find the
problem and rectify it.
4. Do not light the fire until the problem
is rectified.
6.7 SERVICING
The following is a guideline checklist which
can be used during servicing. Note that
other checks may be required (system
dependant):
- Checkuetoensureitisclearandfree
from soot.
- Removebaes,cleanandensurethey
