BERRINGTON SOLID FUEL STOVE INSTALLATION & OPERATING INSTRUCTIONS
GENERAL
Fig.3
When installing, operating and maintaining your
Berrington Stove respect basic standards of fire
safety. Read these instructions carefully before
commencing the installation. Failure to do so may
result in damage to persons and property. Consult
your local Municipal office and your insurance
representative to determine what regulations are in
force. Save these instructions for future reference.
The installation must be completed in accordance
with current National and European Standards and
Local Codes. It should be noted that the require-
ments and these publications may be superseded
during the life of this manual.
Fit the primary air control knob to the flexible drive.
(for the boiler model, ensure that the air damper
knob spacer is placed between the knob and the
flexible drive bracket on the back of the boiler). See
Fig.3
PRE INSTALLATION ASSEMBLY
1. After removing the stove from its pack, open the
ashpit door and remove the contents.
2. Fit the front door handle as shown in Fig.1.
FLUES
Fig.1
Flues should be vertical wherever possible and
where a bend is necessary, it should not make an
angle of more than 45o with the vertical. Horizontal
flue runs should be avoided except in the case of a
back outlet from the appliance, when the length of
the horizontal section should not exceed 150mm.
In order to minimise flue resistance and to make
sweeping easier it is recommended to use 2 x 45o
bends rather than a 90o bend.
The flue termination point must be located to min-
imise any wind effects. Wind effects of suction,
pressure zones and turbulence can be created by
the roof and adjacent objects. Wind effects can also
be created by natural land contours.
3. Remove the stove from the wooden pallet.
4. Unscrew the two 1/4” x 1/2” round head screws
from the base and fit the front ash tray using the
two screws (see Fig.2).
To minimise the wind effects, the flue termination
point should be located a minimum of 600mm from
the roof measured vertically and 2300mm measured
horizontally. Where this termination point does not
suffice it may be necessary to extend the flue pipe
so that the termination point is above the apex. (See
Fig.3)

with a minimum continuous draught of 15 Pascals.
Poor draught will result in poor performance.
Similarly an excessive draught will result in the appli-
ance over firing or being difficult to control. An
excessive draught may require a flue draught sta-
biliser to be fitted. Do not connect this appliance to a
chimney serving another appliance. The minimum
required chimney height is 4.5 metres from the floor
on which the appliance is installed. An existing
masonry chimney should be inspected and if neces-
sary, repaired by a competent mason.

Fig.4
DOWN DRAUGHTS
However well designed constructed and positioned,
the satisfactory performance of the flue can be
adversely affected by down draught caused by near-
by hills, adjacent tall buildings or trees. These can
deflect wind to blow directly down the flue or create
a zone of low pressure over the terminal. A suitable
anti-down draught terminal or cowl will usually effec-
tively combat direct down blow but no cowl is likely
to prevent down draught due to a low pressure zone.

VENTILATION & COMBUSTION AIR
REQUIREMENTS
FLUE PIPES
This appliance is rated at no more than 8kW. It is
imperative that there is sufficient air supply to the
stove in
order to support correct combustion. The air supply
to this appliance must comply with B.S. 8303: Part 1
and current Building Regulations. The minimum
effective air requirement for this appliance is
16.5cm2.
A flue pipe should only be used to connect an appli-
ance to a chimney and should not pass through any
roof space.
Flue pipes may be of any of the following materials:
(a) Cast iron as described in BS 41: 1973 (1981),
or
(b) Mild steel with a wall thickness of at least 3mm,
or
If a draught stabiliser is used then this increases to
40.5cm2. When calculating combustion air require-
ment for this appliance use the following equation: a
total free area of at least 550mm2 per kW of rated
output above 5kW shall be provided. If there is
another air using appliance fitted in the same or
adjacent room, it will be necessary to calculate addi-
tional air supply. All materials used in the manufac-
ture of air vents should be such that the vent is
dimensionally stable and corrosion resistant.
(c) Stainless steel with a wall thickness of at least
1mm and as described in BS EN 10095:
1999 Specification for stainless and
heat resisting steel plate, sheet and strip, for
Grade 316 S11, 316 S13, 316 S16, 316 S31,
316 S33, or the equivalent Euronorm 88-71
designation, or
(d) Vitreous enamelled steel complying with BS
6999: 1989.
Flue pipes with spigot and socket joints should be
fitted with the socket uppermost.
The effective free area of any vent should be ascer-
tained before installation. The effect of any screen
should be allowed for when determining the effective
free area of any vent.
CHIMNEY
The stove is a radiant room heater and must be con-
nected to a chimney of the proper size and type.
The chimney must have a cross sectional area of at
least 19350 square mm (30 square inches) or a
diameter of 150mm (6 “). The chimney should be
checked for soundness and draught before installa-
tion. The stove must be connected to a chimney
Air vents direct to the outside of the building should
be located so that any air current produced will not
pass through normally occupied areas of the room.
An air vent outside the building should not be locat-
ed less than the dimensions specified within the
Building Regulations from any part of any flue termi-
nal.

These air vents must also be fire proofed as per
Building Regulations.
Fig. 5
Air vents traversing cavity walls should include a
continuous duct across the cavity. The duct should
be installed in such a manner as not to impair the
weather resistance of the cavity. Joints between air
vents and outside walls should be sealed to prevent
the ingress of moisture. Existing air vents should be
of the correct size and unobstructed for the appli-
ance in use. If there is an air extraction fan or other
air using appliance fitted in the room or adjacent
rooms where this appliance is fitted, additional air
vents will be required to alleviate the possibility of
spillage of products of combustion from the appli-
ance/flue while the fan is in operation.
6” Cast Iron
Bend
Where such an installation exists, a test for spillage
should be made with the fan or fans and other appli-
ances using air in operation at full rate, (i.e. extrac-
tion fans, tumble dryers) with all external doors and
windows closed. If spillage occurs following the
above operation, an additional air vent of sufficient
size to prevent this occurrence should be installed.
REAR FLUE EXIT
For the rear flue outlet configuration, push in the flue
connector pipe (not supplied) into the flue outlet
socket at the rear of the stove and cement into place
using approved fire cement ensuring that no cement
blocks the flue passageway. (See Fig.7)
FLUE PIPES
Fig. 6
Flue pipes with spigot and socket joints should be fit-
ted with the socket upper most. Clearance to com-
bustibles must be adhered to when fitting the flue
pipe. The flue gas mass flow is 5.4 g/s mineral fuel
and 6.1 g/s wood logs. The mean flue gas temper-
ature directly downstream of the spigot at nominal
heat output is 262°C. The appliance is suitable for
continuous operation on solid mineral fuel and inter-
mittent operation on wood logs.
TOP FLUE EXIT
For the top outlet configuration, connect bend (not
supplied) into flue outlet socket at the rear of the
stove and cement into place using approved fire
cement ensuring that no cement blocks the flue pas-
sageway. (See Fig. 6)
It may be necessary to have an inspection plate in
the flue pipe to assist with access for cleaning the
flue way.

PLUMBING
WATER CIRCUIT TEMPERATURE
The return water temperature should be maintained
at not less than 40°C so as to avoid condensation on
the boiler and return piping. Fitting a pipe thermo-
stat to the return pipe of the gravity circuit and wiring
it into the pump control will ensure rapid circulation
of the hot water.
REGULATIONS
The plumbing must be in accordance with all
relevant regulations and practices. It must include a
gravity circuit with expansion pipe, open to the
atmosphere. The central heating will be pump-dri-
ven as with other types of boilers.
In some circumstances it may be possible to over-
heat the appliance and the water inside will boil.
This will be evident by the sound of a knocking noise
coming from the appliance and pipes around the
house. If this occurs close off all air controls and
manually start the central heating pump if fitted.
Opening the oven doors and hotplate covers will
help to release heat from the appliance. Be aware
that steam and boiling water will be expended from
any open vent from the heating system probably in
the roof space at the expansion tank.
GRAVITY CIRCUIT
The gravity circuit consists of the domestic hot water
tank of 135 litres indirect cylinder, fixed in an upright
position, recommended for hot water storage and it
should be connected to the boiler by 28mm diame-
ter flow and return piping. The pipes should not
exceed 7.8 meters (25ft) in length and cylinder and
pipework should be fully lagged. The shorter the run
of pipe work the more effective the water heating.
In the unlikely event that the appliance is not oper-
ating in freezing conditions the water must be
drained from the boiler to prevent frost damage.
There must be no gate valves on this circuit and it
must have an expansion pipe exhausting to atmos-
phere. Cylinder and pipe work should be lagged to
minimise heat loss.
OPERATING INSTRUCTIONS

heating systems and must not be regarded as a
Never use gasoline or gasoline type lantern fuel,
kerosene, charcoal lighter fluid or similar liquids to
start or ‘freshen up’ a fire in this heater. Keep all
such liquid well away from the heater at all times.

INJECTOR TEE
Where the gravity and central heating circuits join
together to return to the stove we recommend the
use of an injector tee connection, situated as close
to the unit as possible. This type of tee encourages
a stable flow of water through both circuits and
helps to prevent priority being given to the stronger
flow, which is most commonly the pumped central
heating circuit.

(closed to maximum). Setting 4 will provide the
most heat from the appliance. The zero position
may not always be in the 12 o’clock position but the
knob will only rotate once between fully open and
fully closed. (See Fig.10)
LOW / SLUMBER BURN
To achieve an overnight or a low burn rate, close the
air wash slider fully by sliding the lever left using the
ashpan tool and rotate the primary air control knob
in an anticlockwise direction until the lowest burning
rate is found without the fire going out. The exact
setting will be governed by individual requirements.
(See Figs 10 &11)

When burning anthracite and
smokeless fuels.
This appliance has been tested using seasoned
wood logs and manufactured briquetted smokeless
fuel (Ancit) for closed appliances, sized between
20g and 140g. Other fuels are commercially avail-
able and may give similar results. Wood logs up to
400mm long are suitable. All fuels should be stored
under cover and kept as dry as possible prior to use.
WARNING: THE AIR SLIDER IS HOT WHILE
STOVE IS IN USE - USE TOOL TO OPERATE.
WARNING: DO NOT OBSTRUCT PRIMARY
AIR SUPPLY TO THE AIR DUCT AT THE BACK
OF THE STOVE.
Do not use fuels with a coke ingredient as this may
cause the grate to overheat, causing damage.
Reduced outputs will result when fuels of lower
calorific values are used. Never use gasoline or
gasoline type lantern fuel, kerosene, charcoal lighter
fluid or similar liquids to start or freshen up a fire in
this heater. Keep all such liquid well away from the
heater at all times. Operate the stove only with the
fuelling door closed except for re-fuelling.

IMPORTANT NOTES
Now that your Solid Fuel Stove is installed and no doubt you are looking forward to many comforts it will
provide, we would like to give you some tips on how to get the best results from your stove.
1. We would like if you could take some time to read the operating instructions/hints, which we are confident,
will be of great benefit to you.
2. Do not burn fuel with a high moisture content, such as a damp or unseasoned timber. This will only result
in a build up of tar in the stove and in the chimney.

3. Clean the flue-ways of the stove weekly and ensure that there are no blockages. Check flueways before
lighting especially after a shut down period. Please refer to manual for instructions.
4. Before loading fresh fuel into the firebox, riddle fully to remove all ashes, this will allow better and cleaner
burning. See Re-Fuelling Section.
5. Never allow a build up of ashes in the ash pan, as this will cause the grate to burn out prematurely. Empty
the ashpan when re –fuelling.
6. Allow adequate air ventilation to ensure plenty of air for combustion.
7. Do not use as an incinerator burning rubbish/household waste.
8. Do not leave ash door open for long periods as this will over heat the unit causing unnecessary damage.
Close the ash door between removing and replacing the ashpan.
9. Clean the chimney at least twice a year.
10. Burning soft fuels such as timber or peat will stain the glass. Regular cleaning will prevent permanent
staining. Clean with soapy water when cool.
11. Keep all combustible materials a safe distance away from unit, please consult manual for clearance to com-
bustibles table.
12. For safety reasons never leave children or the elderly unaccompanied while stove is in use. Use a fire
guard.
13. Avoid contact with the appliance when in use as stove reaches very high operating temperatures.
14. This appliance should be regularly maintained by a competent service engineer.
Use only replacement parts recommended by AGA. Making unauthorised modifications, or using unauthorised
parts will invalidate your guarantee and may cause damage or injury.

TO CLEAN CHIMNEY OUTLET
These parts are heavy and must be allowed to
cool before removal.
Remove baffle underneath the boiler cross flow
chamber by lifting it upwards and pulling it outwards
and insert cleaning brush. Replace baffle before
lighting fire.
Fig.14
DISPOSAL OF ASHES
The stove is provided with a steel ashpan. This ash-
pan must be emptied every day.
If ashes are allowed to build up to grate level the fire-
bars could be damaged by overheating. We recom-
mend that you remove ashes after you have riddled
the fire following an overnight burn.
Note: The stove should never be operated with the
ashpit door open.
Ashes should be placed in a metal or other non-
combustible container with a tight fitting lid. The
closed container of ashes should be placed on a
non-combustible material, pending final disposal. If
ashes are buried in soil, or otherwise dumped they
should be retained in the closed container until they
are thoroughly cooled.
TO REPLACE DAMAGED GRATE OR GRATE
BAR
Remove the front brick, the back brick, all the left
hand side bricks and both small right side bricks from
the stove, taking care not to damage or break any of
the bricks in the process. Tilt the grate assembly up
on the left hand side of the stove and pull towards
the left side of the stove until the driven rocker bar is
clear of the right hand firebricks. Remove the grate
assembly from the firebox, replace the damaged part
and reassemble the firebox by re-positioning the
grate assembly and then reposition all the firebricks.
Ensure the riddling mechanism works properly from
outside the stove before replacing the firebricks.

FIRE SAFETY
GLASS CLEANING
To provide reasonable fire safety, the following
should be given serious consideration.
The glass will self clean when there is sufficient heat
generated by the burning fuel. If a build-up of cre-
osote occurs on the glass it may be due to draft con-
ditions, poor quality fuel or very low burning for a
long time. It is best to clean the glass when it is
thoroughly cooled.
1. Do not over fire the stove.
2. Over-firing will also damage painted or enamel
finish.
3. Install a smoke detector in the room.
4. A conveniently located class A fire extinguisher
to contend with small fires resulting from burn-
ing embers.
GLASS REPLACEMENT
(a) Open the firedoor fully.
5. A practical evacuation plan.
(b) Remove the screws and the four segments of
the window frame and carefully remove the bro-
ken glass.
6. A plan to deal with a chimney fire as follows:-
(a) Notify the fire department.
(b) Prepare occupants for immediate
evacuation.
(c) Clean the glass recess in the door.
(d) Attach adhesive thermal tape to the perimeter of
the replacement glass.
(c) Close all openings into the stove.
(d) While awaiting the fire department watch for
ignition to adjacent combustibles from over
heated flue pipe or from embers or sparks
from the chimney.
(e) Place the thermal tape side of the glass into
the door recess and replace the four segments
of the window frame.
(f) Tighten screws.
(g) Replace glass only with ceramic glass 5mm
thick. (See Fig.16)
IN CASE OF FIRE
Fig.16
Close all openings into the stove and watch for igni-
tion of adjacent combustibles from over heated
stove, or hot embers or sparks from chimney.
VITREOUS ENAMEL CLEANING
