or 50 mm in size). The coal should be dry.
When burning coal a little extra care is needed. Please take
note of the section "Special Points For Burning Coal".
Only dry well seasoned wood logs 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 logs 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.
HETAS Ltd Appliance Approval only covers the use of Wood
Logs and Smokeless Fuels on this appliance.
Take care not to touch the doors as they will be hot when the
fire is burning. The stove is normally run with the doors shut,
and the doors must be shut if the stove is unattended. Use
the door opening and ashpan tool to open and close the
doors. Turn the right-hand door knob anti-clockwise to open
and clockwise to close (see Fig.1).

DOOR OPERATION
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. Do not light the fire
before the boiler and heating system have been filled with
water as this can damage the boiler.
If the stove is to be used where children and old or infirm
people are present, then a fireguard manufactured in
accordance with BS8423: 2010 must be used.
When the stove is under fire an aerosol spray must not be
used in the vicinity.
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.
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 authorised smokeless fuels may be burned in smoke
control areas on this appliance. Your local fuel supplier or
stove shop will be able to advise you which fuels are available
locally. Take care to only burn good quality fuels in order to
obtain the greatest efficiency and to maintain the life of the
appliance.
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 inch

MULTIFUEL GRATE
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 burning.
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 solid fuel position by moving the tool up until the
handle is in the 1 o'clock position. The grate is put into the
wood position by moving the tool down until the handle is in
the 5 o'clock position. To riddle the appliance when burning
solid fuels the tool should be moved between the 1 o'clock
and 3 o'clock positions 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.
LIGHTING
CONTROLLING THE FIRE
RIDDLING
For correct firing we recommend the use of a stove
pipe thermometer which may be purchased from your
supplier, or directly from Charnwood.
Light the stove using dry kindling wood and paper or fire
lighters. Set the grate into either the wood or solid fuel
position as required. Place the paper, or fire lighters, and
kindling on the grate and cover with a few small dry logs.
Open the airwash and thermostat controls fully (see Fig. 1).
Light the paper or fire lighters. Close the doors until the fuel
is well ignited then load with fuel. Once the fire is up to
temperature the airwash system will begin to work, so allow
the fire to become hot before adjusting the air controls to the
required setting. A flue pipe thermometer is available which
will help you to get the best from your stove.
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 slightly and then empty the
ashpan.
The rate of burning and hence the output is regulated by the
control knob on the side of the fire and the airwash control
(see Fig. 1).
The control knob is linked to a thermostat which senses the
boiler temperature. The number at the front of the knob is
the number at which it is set.
The airwash control should be kept at least slightly open most
of the time to keep the glass clean. It may be fully opened
when rapid heating is required or to help clean any deposits
from the glass. It will not be possible to keep the glass clean if
this control is fully closed, particularly immediately after
refuelling.
When burning solid fuels riddling twice a day is usually
sufficient. When burning wood logs or peat, ash 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 riddling lever and rotate
between the 1 o'clock and 3 o'clock positions several times.
Too much riddling can result in emptying unburnt fuel into the
ashpan and should therefore be avoided. If any clinker forms it
should 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 in the 1 o'clock position for solid
fuel or in the 5 o'clock position for wood).
Keep the firebox well filled but do not overfill to prevent fuel
from spilling over the top of the front fire bars.
Take especial care that logs do 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 blacken. Maximum
filling height is such that fuel cannot fall from the fire when the
doors are opened. Liquid fuels are not to be used on this
stove.
The ashpans should be emptied regularly before they become
too full. Never allow the ash to accumulate in the ashpans so
that it comes in contact with the underside of the grate as this
will seriously damage the grate bars. The ashpans are 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, directly from Charnwood.
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.
REFUELLING
ASH CLEARANCE
SPECIAL POINTS WHEN BURNING COAL
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. Please also note that when burning
coal, some blackening of the glass may occur.
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 "Controlling the
Fire").
For overnight burning the fire doors must be closed.
When burning solid fuel the ashpans should be emptied and
the fire riddled. If the fire is very low then it may be necessary
to add a little fuel and turn the thermostat control up to
maximum for a brief period until the fire is burning brightly
before filling with fuel. When the new fuel has ignited, the
thermostat control should be turned down to the required
setting and the airwash control moved to a low setting. If the
central heating pump is off overnight then the thermostat
may be left at the same setting for both day and night
operation. If the central heating pump is on overnight then set
the thermostat control to give the required level of heating.
Some experimentation will be necessary to find the settings
most suitable for the particular fuel used and the draw on the
chimney.
To revive the fire, empty the ashpans, 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

sooty deposits should then be swept from the plate and into
the fire.
While the throat plate is lowered clean any sooty deposits
from the boiler faces and the airwash tubes.
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.
The chimney should be swept at least twice a year. Where a
top outlet is used it will generally 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 fireplates.
Different types of sweep's brushes are available to suit
different flueways. For prefabricated insulated chimneys the
manufacturers instructions with regard to sweeping should be
consulted.
CHIMNEY SWEEPING
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 reviving.
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.
The glass in the doors is a zero expansion ceramic glass,
capable of withstanding 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 or ceramic hob 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 these can scratch the surface which will
weaken the glass and cause premature failure.
If the appliance is to be shut down for a prolonged period then
the ash should be emptied and the interior of the firebox
cleaned out. The interior, including all moving parts, should be
sprayed with a lubricant/corrosion inhibitor such as WD40.
During this period the fire doors should be left ajar and the air
controls open to allow air circulation through the appliance to
minimize corrosion.
It is important that the throat plate and all the stove flueways
are kept clean. They should be cleaned at least once a week,
and more frequently if necessary. It is necessary to let the fire
out to carry out these operations.
The throat plate is lowered by hand. First, swing the bracket
up to the side. Then lift the throat plate up from its locating
pegs, pull it towards you, then lower as shown in Fig. 3. Any

If the chimney previously served an open fire, it is possible that
the higher flue gas temperature from the stove may loosen
deposits that were previously firmly adhered, with the
consequent risk of flue blockage. It is therefore recommended
that in this case the chimney be swept a second time within a
month of regular use after installation.
Check that:
a) the air inlet is not obstructed in any way,
b) chimneys and flueways are clear,
c) a suitable fuel is being used,
d) there is an adequate air supply into the room,
e) 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 2.5mm water gauge or 25
pa. should be obtained).
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:
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 air controls. This
may also be necessary when re-fuelling the stove. Using a
stovepipe thermometer will help you to operate the stove at
the optimum temperature.
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.
TROUBLE SHOOTING
Fire Will Not Burn
Blackening of Door Glass
d) Wet wood or logs overhanging the front firebars 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 (when the
chimney is warm a draught reading of at least 2.5 mm water
gauge or 25 pa. should be obtained), and that it is not
affected by down-draught.
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.
Check that :
a) The doors are tightly closed.
b) The air controls are set at the minimum setting.
c) the thermostat flap is closed (beneath the stove on the left,
see Fig. 1) and that it is not prevented from closing
completely.
d) The airwash control is closed.
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:

e) A suitable fuel is being used.
f) Door seals and airwash slide are intact.
If the fire is over-fired it will cause premature failure of the
internal fire parts. Overfiring is occurring when any parts of
the fire begin to glow red. To prevent over-firing ensure that:
a) the door seals are kept in good condition, and that the
doors are sealing correctly,
b) the thermostat on the fire is working correctly,
c) a suitable fuel is being used,
d) the fire is not fitted onto a heating system which is too
large.
Do not light the fire if there is any possibility that any parts of
the system may be frozen.
Check that:
a) the fire is burning properly - if not then carry out the checks
under "Fire Will Not Burn".
b) the throat plate is fitted correctly (see Fig. 3) and that it is
not distorted.
c) the door seals are in good condition.
If the hot water goes cold when the pump is turned on, or if
some radiators are hotter than others, then the system may
need balancing, the pump may be pumping the water too
quickly around the system, or the radiators may need
bleeding. Please ask your installer to check these points.
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 controls 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 immediately.
After a chimney fire the chimney should be carefully
examined for any damage. Expert advice should be sought if
necessary.
This appliance has been approved by HETAS Ltd. as a

HEALTH AND SAFET Y PRECAUTIONS
PERFORMANCE
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 totaling at least 80.3cm² (12.45
square inches) to provide combustion air. It must be supplied
via a permanently open vent which must be positioned such
that it is not liable to blockage. This is particularly necessary if
the room is double glazed.
Do not light the fire before the boiler has been connected to
the system and filled with water, as this can cause serious
damage to the boiler.
In addition to these instructions the requirements of BS.8303
and BS EN15287-1:2007 must be fulfilled. Local Authority
Bylaws and Building Regulations regarding the installation of
Solid Fuel burning appliances, flues and chimneys must also be
observed, including those referring to national and European
Standards.
Electrical connections to central heating controls shall be made
by competent persons and shall meet the requirements of the
current issue of British Standard BS7671 Requirements for
Electrical Installations.
The rated output of the Country 16B Multifuel is 13.2 kW
(45,040 Btu/h) to water and 6.4 kW (21,838 Btu/h) to the
room. The outputs were obtained burning anthracite over a
4.0 hour re-fuelling cycle with the doors closed.
The heat output to the room is directly proportional to the
heat output to water. This means that if the water heating
load is less than the rated output then the room heating will
be reduced by the same proportion. This must be borne in
mind when calculating the heating requirements.
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 must not be

less than 150 mm (6 inches) either square or round. This
stove must not be used in a shared flue.
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 EN
1587-1:2007 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 2.54
mm (0.10 inches) water gauge. If in doubt about the chimney
seek expert advice.
The stove must stand on a fireproof hearth a minimum of
12mm thick and must be situated at least 150mm (6 inches)
from any combustible material to the sides or rear. 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
HEARTH AND FIRE SURROUND
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.

CENTRAL HEATING SYSTEM
SYSTEM CONTROLS
The central heating system must comply with BS:5449 part 1.
If the system is to be a combined heating and domestic hot
water system then a double feed indirect hot water storage
cylinder to BS:1556 part 1 should be used. In order to prevent
the build up of scale and corrosion a suitable inhibitor should
be used. The system must be correctly vented as shown in
Figs. 5 and 6. The height differential between the header tank
and the appliance must not exceed 15.2 metres (50 feet).
If all four boiler tappings are used then, if possible, diagonal
pairs should be connected for domestic hot water and central
heating. Where a common return is used an injector tee must
be incorporated into the system as shown in Fig. 7. This will
ensure that a good domestic hot water supply is maintained
when the central heating pump is operating.
The system must incorporate a gravity circuit which will
normally heat the domestic hot water and an unvalved
radiator with an output of at least 1 kW. When the appliance
is not connected to a domestic hot water system the unvalved
radiator(s) on the gravity circuit must have an output of at
least 1.25 kW. This is to prevent boiling in case of pump
failure. All pipework in the primary circuit must be 28 mm
diameter and the gravity flow pipe must rise continuously from
the boiler to the open vent. Two typical systems are shown in
Figures 5. and 6.
If the appliance is used to heat a small central heating system
then the heat output to the room from the fire will be
reduced.
Fitting a radiator in the same room as the fire is recommended
as it will allow greater flexibility in the way that the system is
operated as well as ensuring that there is sufficient heat.
Connect the heating system to the boiler ensuring that the
primary flow pipe rises continuously from the appliance to the
vent. Fill the system with water and check for leaks.
The circulating pump may be controlled by means of time
switches, room thermostats or outdoor thermostats.
Radiators may be either manually or thermostatically
controlled. These controls will all work in conjunction with
the thermostat on the appliance and the low limit pipe
thermostat.

We recommend fitting a pipe thermostat onto the gravity
return to act as a low limit thermostat. This should be wired
into the mains supply to the pump so that if the gravity return
temperature drops below 45°C then the pump will cut out.
This will help to prevent condensation forming on the boiler
faces and will thereby increase the life of the boiler. It will also
ensure that priority is given to the domestic hot water. These
thermostats are available from ourselves if you are unable to
obtain them locally.
There are several ways of connecting the stove to the flue.
These are illustrated in figures 8 to 11.
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
must 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. 12. Ensure the clamping plate does not prevent the
throat plate from seating correctly. All flue connections must
be well sealed.

PRE LIGHTING CHECK
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. 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 8 to 11.
Before lighting the fire, check the cold setting distance of the
thermostat. This is fitted under the firebox. Removing the ash
lip will give easier access.
With the control knob at the minimum setting the flap should
be just closed as shown in Fig. 13. To adjust the distance slacken
the locking nut and adjust as necessary. When set correctly re-
tighten the locking nut. Ensure that the flap opens and closes
freely as the knob is turned, and that the opening is completely
covered when the flap is closed.
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.
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.
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 for soundness.
The central heating pump should be adjusted to give the
correct water flow against the circuit resistance and the
system should be correctly balanced.
On completion of the installation and commissioning, please
leave the operating instructions with the customer and advise
on the use of the appliance and any controls on the system.
