OPERATING INSTRUCTIONS
Before lighting the stove check with the
installer that the work and checks
described in the Installation Instructions
have been carried out correctly and that
the chimney has been swept, is sound and
free from any obstructions.
FUELS
Wood
Wood must be dry and well seasoned.
Ideally it should be cut, split and stacked
under cover for at least a year and
preferably two years before being burnt.
Hard woods, such as Ash, Beech and Oak
are preferable to Soft woods such as Pine.
The wood should be burnt in a bed of ash
on the flat base of the stove.
Burning wet unseasoned wood will result
in heavy tar deposits in the chimney and
reduced outputs.
Peat
Cut peat should be dried before burning
to reduce tar deposits. Peat should be
burnt in the same manner as wood, on the
flat base of the stove in a bed of ash.
House Coal
Doubles, Trebles and Cobbles may be
burnt, do not use singles or coal dust (or
"slack"). Coal must only be burnt with
the optional coal kit, burning it on the flat
base of the stove may cause damage. A
little extra care is needed when burning
coal, please refer to the section "Special
Points When Burning House Coal" later
in the instructions.
Smokeless Fuel
A wide variety of smokeless fuels are
available, many of which are suitable for
use on your Country 8. Some of these are
listed below:
Ancit
Anthracite Large Nuts
Centurion
Cosycoke
Extracite
Homefire
Maxibrite
Phurnacite
Welsh Dry Steam Coal (Large Nuts).
Smokeless fuels must only be burnt with
the optional coal kit, burning it on the flat
base of the stove may cause damage.
At first you may find it helpful to try
several fuels to find the most suitable. If
you are unable to obtain the fuel you
want ask your supplier, or an approved
fuel distributor to suggest an alternative.
Only smokeless fuels may be burnt in
smoke control areas.
DOOR OPERATION
Turn the right-hand door knob
anti-clockwise to open and clockwise to
close, (see Fig. 1.)
FITTING THE OPTIONAL
COAL KIT
Before burning coal or smokeless fuel the
coal kit must be fitted. This consists of a
grate and an ashpan.
Fit the legs onto the grate, ensuring that
the grate is the right way up. Remove the

front fence and place the grate in the
stove so that it comes hard up against the
back fire brick. Replace the front fence so
that the slope rests on the top of the
grate. Slide the ashpan in under the grate.
LIGHTING
On initial lighting, the stove may smoke
and give off an odour as the silicon paint
with which the firebox is painted reacts
to the heat. This is normal and will cease
after a short time, but meanwhile the
room should be kept well ventilated.
At first only light a small fire and burn it
slowly for two hours to allow any residual
moisture in the bricks to evaporate.
IMPORTANT When burning wood or
peat on the base of the stove there must
be a bed of ash to prevent damage to the
base. When first lighting the stove, if
there is no ash available then a make a
layer of sand or earth about 12mm (1/2
inch) thick on the base to prevent any
damage.
The stove may be lit using dry kindling
wood and paper or fire lighters. Place the
paper, or fire lighters, and kindling on the
base or the grate and cover with
approximately 2 inches of fuel. Open the
air slides in the doors and open the
airwash control fully (see Fig. 1). Light
the paper or fire lighters. Close the doors
until the fuel is well ignited then load
with fuel and adjust the air controls to the
required setting.
When relighting the stove, leave the ash
on the base, if burning wood or peat,
unless it is beginning to block the slots in
the front fence, in which case some of it
may be removed. If burning solid fuel
clear the grate and empty the ashpan
before relighting.
CONTROLLING THE FIRE
The rate of burning and hence the output
is controlled by the door air slides and
the airwash control (see Fig. 1).
The air slides in the doors should be used
when lighting or when rapid burning is
required. They should not be left fully
Page 2
Country 8 &12 WB 6/97
Page 3
open for long periods as this can cause
over-firing. For overnight burning they
should be closed.
The airwash control is used most of the
time to control the burning rate and to
keep the glass clean. Fully extended gives
full airwash for faster burning and clean
glass whereas fully closed gives slow
overnight burning. It will not be possible
to keep the glass clean if this control is
fully closed, particularly just after
refuelling.
REFUELLING
Keep the firebox well filled but do not
allow fuel to spill over the top of the
front fire bars.
Care should be taken, especially when
burning wood, that fuel does not project
over the front fire bars or damage to the
glass may be caused when the doors are
closed, it can also cause the glass to black
up.
ASH CLEARANCE
When burning wood or peat the ash
should be allowed to build up on the base
of the fire. It will only be necessary to
remove some ash once or twice a week
when it begins to restrict the flow of air
through the front fence.
When burning coal or smokeless fuel the
ashpan should be emptied regularly
before it becomes too full, generally once
or twice a day. Never allow the ash to
accumulate in the ashpan so that it comes

in contact with the underside of the grate
as this will seriously damage the grate.
Care should be taken to ensure that ash is
cool before emptying it into plastic liners
or bins. After emptying the ashpan, poke
the fire with a poker to clear the firebed
of ash.
To make ash removal easier, when
burning coal or smokeless fuel, there is a
special Charnwood ash carrier available.
This enables the whole ashpan to be
placed in the sealed carrier and taken
outside. These may be purchased from
your supplier or, in case of difficulty,
from ourselves.
SPECIAL POINTS WHEN
BURNING HOUSE COAL
When loading the stove take care not to
smother the fire, instead fill the firebox
in two stages waiting between each stage
for the flames to appear above the fire.
After a period of slumbering always open
the door air slides and wait until flames
appear above the fuel bed before opening
the doors.
Burning coal will produce more soot
deposits than other fuels, especially if the
fire is run at low levels for long periods.
It is therefore vital to clean the throat
plate regularly, weekly cleaning is
recommended.
Never fully close the Airwash control
when burning coal.
RUNNING THE FIRE WITH
THE DOORS OPEN
The fire may be run with the doors open
if required. The more reactive fuels, such
as wood, peat, coal and homefire, will
burn better with the doors open than fuels
like phurnacite and ancit. Do not leave
the fire unattended with the doors open.
OVERNIGHT BURNING
For overnight burning the fire doors must
be closed.
When burning wood load some large logs
on the fire and allow to burn for half an
hour before closing the door air slides,
(this will help to reduce tar deposits in
the chimney.) Leave the airwash control
slightly open to help keep the glass clear.
When burning coal or smokeless fuel, if
the fire is very low then open the air
controls and revive the fire, adding a
small amount of fuel if necessary. Empty
the ashpan and poke the fire, load with
fuel, and then close the door air slides.
The airwash control should be kept
slightly open to help keep the door glass
clean.
Some experimentation may be necessary
to find the setting most suitable for the
type of fuel being used and the draw on
the chimney.
To revive the fire, empty the ashpan, (if
burning coal or smokeless fuel), poke the
fire, and open the air controls to
maximum. When the fire is burning well
load on more fuel as necessary and adjust
the air controls to the desired setting.
CLEANING AND
MAINTENANCE
The stove is finished with a high
temperature paint which will withstand
the temperatures encountered in normal
use. This may be cleaned with a damp
lint-free cloth when the stove is cold.
Should re-painting become necessary,
high temperature paints are available
from your supplier or from stove shops.
Most deposits on the glass may be burnt
off simply by running the fire at a fast
rate for a few minutes. If it becomes
necessary to clean the glass then open the
doors and allow them to cool. Clean the
glass using a damp cloth and then wiping
over with a dry cloth. Any stubborn
deposits on the glass may be removed
with a proprietary stove glass cleaner or
ceramic hob cleaner. Do not use abrasive
cleaners or pads as theses can scratch the
surface which will weaken the glass and
cause premature failure.
THROAT PLATE AND
FLUEWAY CLEANING
It is important that the throat plate and all
the stove flueways are kept clean in order
to prevent potentially dangerous fume
emission. They should be cleaned at least
monthly, and more frequently if
necessary. It is not necessary to let the
fire out completely to carry out these
operations.
The front of the throat plate is pulled
forward and then lowered as shown in
Fig. 2. Any sooty deposits should then be
Page 3
Country 8 &12 WB 6/97
Page 4
swept from the plate and into the fire.
Return the throat plate to its correct
position - raise the front of the plate,
push it back and then lower it onto the
retaining lugs.
CHIMNEY SWEEPING
The chimney should be swept at least
twice a year. Where the top outlet or
vertical rear flue connector is used it will
generally be possible to sweep the
chimney through the appliance.
First remove the front fence and the
throat plate. Then sweep the chimney
ensuring that soot is removed from all
horizontal surfaces after sweeping.
In situations where it is not possible to
sweep through the appliance the installer
will have provided alternative means,
such as a soot door. After sweeping the
chimney the appliance flue outlet and the
flue pipe connecting the stove to the
chimney must be cleaned with a flue
brush.
After clearing any soot from within the
stove, replace the throat plate (see Fig.
2.) and the front fence.
Different types of sweep’s brushes are
available to suit different flueways. For
standard brick chimneys a wire centre
sweep’s brush fitted with a guide wheel
is recommended. For prefabricated
insulated chimneys the manufacturers
instructions with regard to sweeping
should be consulted.
TROUBLE SHOOTING
Fire Will Not Burn.
Check that:
a) the air inlet is not obstructed in any
way,
b) chimneys and flueways are clear,
c) that a suitable fuel is being used,
d) that there is an adequate air supply
into the room,
e) that an extractor fan is not fitted in the
same room as the stove.
f) there is sufficient draw in the chimney.
Once the chimney is warm a draught
reading of at least 2.5 mm (0.10 inches)
water gauge should be obtained.
Door Glass Blacks Up
Differences in chimney draughts mean
that the best settings of the air controls
will vary for different installations. A
certain amount of experimentation may
be required, however the following points
should be noted and with a little care
should enable the glass to be kept clean
in most situations:
a) The airwash relies on a supply of
heated air to keep the glass clean,
therefore, when lighting the stove allow
the firebed to become well established
before closing the airslides. This may
also be necessary when re-fuelling the
stove.
b) When re-fuelling keep the fuel as far
back from the front fence as possible, do
not try to fit too much fuel into the
firebox.
c) Never completely close the airwash
control - as a guide it should be at least a
quarter open.
d) The airslides in the doors may be kept
slightly open to assist in keeping the
glass clean.
e) Wet wood or logs overhanging the
front fence will cause the glass to
blacken.
It is always more difficult to keep the
glass clean when running the stove very
slowly for long periods.
If blackening of the glass still occurs
check that all flue connections and the
blanking plate are well sealed. It is also
important that the chimney draw is
sufficient and that it is not affected by
down-draught.. When the chimney is
warm a draught reading of at least 2.5
mm (0.10 inches) water gauge should be
obtained.
When burning coal some blackening of
the glass may occur below the level of the
front fence. This will not obscure the
view of the fire or affect its performance.
Fume Emission.
Warning Note: Properly installed and
operated this appliance will not emit
fumes. Occasional fume from de-ashing
and re-fuelling may occur. Persistent
fume emission is potentially dangerous
and must not be tolerated. If fume
emission does persist, then the
following immediate actions should be
taken:
a) Open doors and windows to ventilate
the room.
b) Let the fire out and safely dispose of
the fuel from the appliance.
c) Check for flue or chimney blockage,
and clean if required.
d) Do not attempt to re-light the fire
until cause of fume has been identified,
if necessary seek professional advice.
The most common cause of fume
emission is flueway or chimney blockage.
For your own safety these must be kept
clean.
Fire blazing out of control
Check that :
a) The doors are tightly closed.
b) The airslides are turned down to the
minimum setting.
c) The airwash control is closed.
d) A suitable fuel is being used.
e) Door seals and airwash slide are intact.
Chimney Fires.
If the chimney is thoroughly and regularly
swept, chimney fires should not occur.
However, if a chimney fire does occur
close the door air slides and the airwash
control, and tightly close the doors of the
appliance. This should cause the chimney
fire to go out in which case the controls
should be kept closed until the stove has
gone out. The chimney and flueways
should then be cleaned. If the chimney
fire does not go out when the above
action is taken then the fire brigade
should be called immediately.
After a chimney fire the chimney should
be carefully examined for any damage.
Expert advice should be sought if
necessary.

INSTALLATION INSTRUCTIONS
HEALTH AND SAFETY
PRECAUTIONS
Please take care when installing the stove
that the requirements of the Health and
Safety at Work Act 1974 are met.
Some types of fire cement are caustic and
should not be allowed to come into
contact with the skin. In case of contact
wash with plenty of water.
If there is a possibility of disturbing any
asbestos in the course of installation then
please use appropriate protective
equipment.
There must not be an extractor fan fitted
in the same room as the stove as this can
cause the appliance to emit fumes into
the room.
There must be an adequate air supply
into the room in which the appliance is
installed totalling at least 100 square cm.
(16 square inches) to provide combustion
air. This is particularly necessary if the
room is double glazed.
In addition to these instructions the
requirements of BS.8303 and BS.6461 Pt
1&2; 1984 must be fulfilled. Local
Authority Bylaws and Building
Regulations regarding the installation of
Solid Fuel burning appliances, flues and
chimneys must also be observed.
PERFORMANCE
The output of the Country 8 WB is 8.0
kW (27,300 Btu/h). The output of the
Country 12 WB is 12.0 kW (40,900
Btu/hr). The optional add-in boiler has an
output of 2.9 kW (10,000 Btu/h), if the
boiler is fitted then the heat output to the
room will be reduced by this amount.
These outputs are based on a 2 hourly
re-fuelling cycle burning seasoned
hardwood logs, or a 4 hourly re-fuelling
cycle burning coal or smokeless fuel.
CHIMNEY
In order for the appliance to perform
satisfactorily the chimney height must not
be less than 4 metres measured vertically
from the outlet of the stove to the top of
the chimney. The internal dimensions of
the chimney should preferably be 175 mm
(7 inches) or 200mm (8 inches) either
square or round and MUST NOT BE
LESS THAN 150 mm (6 INCHES).
If an existing chimney is to be used it
must be swept and checked, it must be in
good condition, free from cracks and
blockages, and should not have an
excessive cross sectional area. If you find
that the chimney is in poor condition then
expert advice should be sought regarding
the necessity of having the chimney lined.
If it is found necessary to line the
chimney then a lining suitable for Solid
Fuel must be used.
If there is no existing chimney then a
prefabricated block chimney or a twin
walled insulated stainless steel flue to
BS.4543 can be used either internally or
externally. These chimneys must be fitted
in accordance with the manufacturers
instructions and Building Regulations.
Single wall flue pipe is suitable for
connecting the stove to the chimney but is
not suitable for using for the complete
chimney.
If it is found that there is excessive draw
in the chimney then a draught stabilizer
should be fitted.
It is important that there is sufficient
draw in the chimney and that the chimney
does not suffer from down-draught. When
the chimney is warm the draw should be
not less than 2.5mm (0.10 inches) water
gauge. If in doubt about the chimney seek
expert advice.
HEARTH AND FIRE
SURROUND
The stove must stand on a fireproof
hearth and must be situated at least
300mm (12 inches) from any combustible
material. There must be a gap behind the
stove of at least 25mm to allow air to
enter the airwash inlets. The positioning
of the stove and the size of the hearth are
governed by building regulations for
Class 1 appliances. These building
regulations state that the hearth must
extend in front of the stove by at least
300mm (12 inches) and to the sides of
the stove by at least 150mm (6 inches). If
in doubt as to the positioning of the stove
expert advice should be sought either
from the supplier or the local building
inspector.
The fireplace must allow good circulation
of air around the appliance to ensure that
maximum heat is transferred to the room
and also to prevent the fireplace from
overheating. A gap of 150mm (6 inches)
each side and 300mm (12 inches) above
the appliance should give sufficient air
circulation. If a wooden mantelpiece or
beam is used in the fireplace it should be
a minimum of 460mm (18 inches), and
preferably 600mm (24 inches) from the
appliance. In some situations it may be
necessary to shield the beam or
mantelpiece to protect it.
HOT WATER SYSTEM
The optional add-in boiler which may be
fitted in the appliance has an output
sufficient for domestic hot water heating.
If the boiler is fitted then the room
heating will be reduced.
The hot water system should be a gravity
circuit and must be correctly vented as
shown in Fig. 3.
A double feed indirect hot water storage
cylinder to BS:1566 part 1 should be used
in most situations, unless the appliance is
to be fitted in a soft water area in which
case a direct hot water cylinder may be
used provided that the boiler is glass
lined.
All pipework in the primary circuit must
be 28mm diameter and the flow pipe
must rise continuously from the boiler to
the open vent.
If an indirect cylinder is used then the
primary circuit should be filled with a
suitable inhibitor to prevent the build up
of scale and corrosion.

FITTING THE OPTIONAL
ADD-IN BOILER
The boiler replaces the rear firebrick.
Before fitting the boiler, remove the front
fence, the throat plate and the rear
firebrick. Knock out the knock-outs for
the boiler tappings in the back of the
firebox.
Remove the back nuts and washers
supplied with the boiler and fit the boiler
into the appliance. Place the fibre
washers over the tappings on the outside
of the appliance and fit the two backnuts,
ensuring that the boiler is held tightly
against the rear inside face of the
appliance and that the top edge of the
boiler is level or runs uphill to the flow
tapping.
Gaps between the boiler and the
firebricks should be filled with fire
cement.
Connect the boiler to the heating system
ensuring that the flow pipe rises
continuously from the boilerto the open
vent. Fill the system with water and
check for leaks.

CONNECTIONS TO FLUES
There are several ways of connecting the
stove to the flue. These are illustrated in
Figs. 4 to 7.
If the optional vertical rear flue connector
is used then the chimney may be swept
through the appliance.
Horizontal lengths of flue must be kept to
a minimum and should not be more than
150mm (6 inches) long. The sealing face
of the flue collar must be coated with fire
cement before fixing to the body of the
stove using the two screws provided. The
blanking plate must be removed, sealed
with fire cement and refitted, care being
taken to ensure that the fold on the
clamping plate is in line with the lugs on
the firebox as shown in Fig. 8. Ensure
that the clamping plate does not prevent
the throat plate from seating correctly. All
flue connections must be well sealed.
SOOT DOORS
It is possible to pass a 16 inch diameter
sweeps brush through the appliance but
in most back outlet installations it will be
necessary to have a soot door to enable
the chimney to be swept. The optional
vertical rear flue connector does allow the
