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.
The following fuels may be burnt on
this stove. Please pay careful
attention to the special points made
with each type of fuel as they will
help you to get the best from your
stove. It must be remembered that
only smokeless fuels may be burnt in
smoke control areas on this stove. If
you are not sure whether you are in a
smoke control area, then please check
with your Local Authority.
Smokeless Fuels
The recommended smokeless fuels
which are suitable for use in smoke
control areas on this stove are as
Ancit, (Phurnacite Plus)
Anthracite Large Nuts,
Sunbrite Doubles,
Welsh Dry Steam Coal (Large Nuts).
Housecoal doubles, trebles or cobbles
may all be burnt. Do not use singles,
small nuts, or coal dust
It is important that large size coal is
used (ie. larger than 2’’ or 50 mm in
size). The coal should be dry.
Only dry well seasoned wood should
be burnt on this appliance as burning
wet unseasoned wood will give rise to
heavy tar deposits in the stove, on the
glass and within the chimney. For the
same reason hard wood is better than
soft wood. Burning wet unseasoned
wood will also result in considerably
reduced outputs. The wood should be
cut and split and then left to season
in a well ventilated dry place for at
least one year but preferably two
years before use.
Ensure that the peat is well dried
before use. Burning wet peat will
give rise to heavy tar deposits and
reduced outputs.
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, an
approved fuel distributor, or your
local British Coal office to suggest an
Use the multi-purpose tool to open
and close the doors. Turn the
right-hand door knob anti-clockwise
to open and clockwise to close.(see
When burning bituminous coal a
little extra care is needed. Please take
note of the section ‘‘Special Points
For Burning Coal’’.

Your Charnwood stove is fitted with
a multifuel grate which enables both
solid fuels and wood to be burned
equally effectively. The grate has two
positions:1) In the solid fuel position the grate
bars are vertical with gaps in between
allowing the primary combustion air
to come up through the grate and
through the fuel bed.
2) In the wood position the grate bars
are horizontal, allowing the
combustion air to come round the
sides of the grate and over the top of
it. When in the wood position ash is
able to build up on the grate as is
necessary for effective wood or peat
Movement of the grate from one
position to the other is effected using
the tool supplied as shown in fig.2.
The grate is put into the wood
position by moving the tool clockwise
until the handle is vertical. The grate
is put into the solid fuel position by
moving the tool anticlockwise until
The stove may be lit using dry
kindling wood and paper or fire
lighters. Set the grate into either the
wood position or the solid fuel
position as required. Place the paper,
or fire lighters, and kindling on 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.
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.
When relighting the stove, riddle (if
burning solid fuel), remove any
clinker from the firebed and then
empty the ashpan.
The rate of burning and hence the
output is controlled by the door air
slides and the airwash controls (see
The door airslides are used when
lighting and requiring rapid heating.
They may be left slightly open to help
keep the glass clean.
the handle is horizontal. To riddle
the appliance when burning solid
fuels the tool should be moved from
the ‘3 o’clock’ to the ‘5 o’clock’
position several times. When burning
wood or peat the ash should be
allowed to build up and riddling
should only be carried out once or
twice a week.
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 after refuelling.
When burning solid fuels riddling
twice a day is usually sufficient.
When burning wood or peat, ash
Page 4
Country 10/93
should be allowed to build up and
generally weekly riddling will be
sufficient. The fire should be riddled
with the doors shut (see Fig 2.) Place
the tool onto the riddler rod and
rotate between the ‘3 o’clock’ and ‘5
o’clock positions several times. Too
much riddling can result in emptying
unburnt fuel into the ashpan and
should therefore be avoided. Clinker
should regularly be removed from the
firebed. After riddling, the grate
should be put back into the solid fuel
or wood position as required (the tool
should be horizontal for solid fuel or
vertical for wood).
Keep the firebox well filled but do
not overfill to prevent fuel from
spilling over the top of the front fire
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 .
The ashpan should be emptied
regularly before it becomes too full.
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 bars.
The ashpan is handled using the tool
provided. Care should be taken to
ensure that ash is cool before
emptying it into plastic liners or bins.
To make ash removal easier there is a
special Charnwood ash carrier
available. This may be purchased
from your supplier or, in case of
difficulty, from ourselves.
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
turn the air control up to maximum
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.
find the settings most suitable for the
particular fuel used and the draw on
the chimney. To revive the fire,
empty the ashpan, riddle, and open
the air controls to maximum. When
the fire is burning well load on more
fuel as necessary and move the air
controls to the desired setting.
When burning wood use large logs
rather than small ones. Proceed as
above, but do not riddle the fire
either when shutting down or
Never fully close the Airwash control
when burning coal.
The grate should be kept in the wood
burning position and should not be
riddled until the ash becomes so deep
that it begins to block the passage of
air into the firebox at the side of the
grate. When this is the case do not
remove all of the ash using the
riddling mechanism but keep a layer
about half an inch thick as this
enables the wood to burn more
effectively. When burning wood or
peat use the airwash control in the
same way as described (see
keep the door airslides closed once
the desired temperature has been
The glass in the doors is a zero
expansion ceramic glass which will
not crack due to the heat of the fire.
Before cleaning the glass 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. Some deposits on the
glass may be burnt off simply by
running the fire at a fast rate for a
few minutes. Do not use abrasive
cleaners or pads as theses can scratch
the surface which will weaken the
glass and cause premature failure.
It is important that the throat plate
and all the stove flueways are kept
clean. When burning smokeless fuels
they should be cleaned monthly.
When burning other fuels they should
be cleaned at least once a week, and
more frequently if necessary. It is not
necessary to let the fire out
completely to carry out these
The throat plate is lowered using the
tool. The front of the throat plate is
pulled forward and then lowered as
shown in figure 3. Any sooty deposits
should then be swept from the plate
and into the fire.
For overnight burning the fire doors
must be closed.
When burning solid fuel the ashpan
should be emptied and the fire
riddled. The air controls should be
turned up to maximum for a brief
period and then when the fire is
burning brightly it should be loaded
with fuel. When the new fuel has
ignited, the door airslides should be
almost closed and the airwash control
moved to a low setting. Some
experimentation will be necessary to

re-painting become necessary, high
temperature paints are available from
your supplier or from stove shops.
Return the throat plate to it’s correct
position - raise the front of the plate,
push it back and then lower it onto
the retaining lugs.
The stove is finished with a high
temperature paint which will

The chimney should be swept at least
twice a year. In most installations
where a top outlet is used it will be
possible to sweep the chimney
through the appliance.
First remove the side fire plates, front
firebars 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. 3), the front firebars, and side
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
Fire Will Not Burn.
Check that:
a) the air inlet is not obstructed in
any way,
b) that chimneys and flueways are
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 0.10
inches water gauge should be
Door Glass Blacks Up
Keeping the glass clean requires a
certain amount of experimentation
due to the differences in the draw of
different chimneys. The following
points should be noted and with a
little care should enable the glass to
be kept clean in most situations:
immediate actions should be taken:
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.
a) Open doors and windows to
ventilate the room.
b) Let the fire out and safely
dispose of the fuel from the
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.
b) When re-fuelling keep the fuel as
far back from the front firebars 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 firebars will cause the glass to
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 the top of the stove is
bolted on securely, and that the seal
between the top and the body is
intact. Also check that all flue
connections and the blanking plate
are well sealed. It is also important
that the chimney draw is sufficient,
(when the chimney is warm a
draught reading of at least 0.10
inches water gauge should be
obtained), and that it is not affected
by down-draught.
When burning coal some blackening
of the glass may occur below the
level of the front firebars. 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
Page 6
Country 10/93
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
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 damper are
intact. (The airwash damper is
situated in the centre of the stove,
underneath the front shelf).
Chimney Fires.
If the chimney is thoroughly and
regularly swept, chimney fires should
not occur. However, if a chimney fire
does occur turn the controls to the
minimum setting, and tightly close
the doors of the appliance. This
should cause the chimney fire to go
out in which case the control should
be kept at the minimum setting 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
After a chimney fire the chimney
should be carefully examined for any
damage. Expert advice should be
sought if necessary.
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.
The output of the Country 12 LC and
FT is 12.0 kW (40,900 Btu/h), the
Country 12 HC output is 12.5kW
(42650 Btu/h). The output of the
Country 8 LC and FT is 8.0 kW
(27,300 Btu/h) the Country 8 HC
output is 8.5 kW (29,000 Btu/h). The
optional add-in boilers for all
Country models have 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.
The outputs were obtained burning
smokeless fuel over a four hourly
re-fuelling cycle.
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
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
Page 7

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 0.10 inches water gauge. If in
doubt about the chimney seek expert
The stove must stand on a fireproof
hearth and must be situated at least
300mm (12 inches) from any
combustible material. 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.
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
The hot water system should be a
gravity circuit and must be correctly
vented as shown in Fig. 6.
A double feed indirect hot water
storage cylinder to BS:1556 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.
The boiler for the Country 12
replaces the rear firebrick, the boiler
for the Country 8 replaces the rear
and righthand side firebricks.
Before fitting the boiler, remove the
front firebars, the side and back fire
plates and the appropriate
firebrick(s). Knock out the
knock-outs for the boiler tappings in
the back of the firebox.
Remove the backnuts and fibre
washers from the boiler tappings and
fit the boiler into the appliance. Place
the fibre washers over the tappings
on the outside of the appliance and fit
the 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. On the
Country 8 also ensure that the boiler
is fitted tight against the righthand
side of the firebox.

using the two screws provided. The
blanking plate should be removed,
sealed with fire cement and refitted,
care being taken to ensure that it is
fully rotated to the stop provided. All
flue connections must be well sealed.
Ensure that the flat top or canopy is
securely bolted to the body of the
It is possible to pass a 16’’ 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.
This may either be in the actual
brickwork of the chimney or in the
register plate. Various types and
positions of soot doors are shown in
figures 4 to 6.
Gaps between the boiler and the
firebricks should be filled with fire
cement. Replace the back fireplate,
the side fireplates, the front firebar
and the throat plate.
Connect the boiler to the heating
system ensuring that the flow pipe
rises from the boiler. Fill the system
with water and check for leaks.
There are several ways of connecting
the stove to the flue. These are
illustrated in figures 4 to 7.
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
should be coated with fire cement
before fixing to the body of the stove
Extension legs are available as an
option for the Country 8. These raise
the stove 65 mm (2.6 inches). They
clamp onto the existing legs using
the fixing screw provided. The leg
with the hole must be fitted at the
front right to allow the airwash
control to operate.
Before initial lighting the following
points should be checked :1. The bottom grate bars must all be
fitted and should move freely and
easily when the riddling mechanism
is operated.
Page 9
Country 10/93
2. The plates round the sides and
back of the grate must be in position
and sitting correctly.
3. The throat plate must be fitted in
the roof of the appliance and should
be checked to ensure that it has not
become dislodged in transit. The
method of location and positioning of
the throat plate is shown in fig 3.
4. The top or canopy must be securely
bolted to the body of the stove using
the fixings provided to ensure proper
On completion of the installation and
after allowing a suitable period of
time for the fire cement and mortar to
dry out, the stove should be lit and
checked to ensure that smoke and
fumes are taken from the appliance
up the chimney and emitted safely.
Also check all joints and seals. On
completion of the installation and
commissioning please leave the
operating instructions with the
customer and advise them on the use
of the appliance.
