MULTIFUEL GRATE  
Airwash  
Control  
Closed  
Your Charnwood is fitted with a  
multifuel grate which enables solid  
fuel, wood and peat to be burned  
equally effectively.  
Open  
If a mixture of wood and solid fuel,  
or peat and solid fuel, is to be burnt  
then keep the grate in the solid fuel  
position.  
The grate has two positions. One for  
solid fuel, the other for wood and  
peat. When in the solid fuel position  
ash can fall through the grate and  
into the ashpan. When in the wood  
position ash is able to build up on the  
grate as is necessary for effective  
wood or peat burning.  
LIGHTING  
Set the grate into either the wood  
position or the solid fuel position as  
required. Place some paper and dry  
kindling wood or fire lighters on the  
grate and cover with a small amount  
of fuel. Turn the thermostat control  
knob to the maximum setting, fully  
open the airwash control and light  
the paper or fire lighters. Leave the  
doors slightly ajar until the fuel is  
well ignited then load with more fuel,  
close the doors and adjust the

airwash control slightly open most of  
the time to keep the glass clean. It  
will not be possible to keep the glass  
clean if the airwash control is fully  
closed, particularly after refuelling.  
The number at the top of the control  
knob is the number at which it is set,  
the higher the number the faster the  
burning rate.  
On initial lighting, the fire 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. In the meantime the room  
should be kept well ventilated.  
Before relighting the fire, riddle,  
remove any clinker from the firebed  
and empty the ashpan.  
RUNNING THE FIRE  
WITH THE DOORS  
OPEN  
CONTROLLING THE  
FIRE  
Control  
Knob  
The fire may be run with the doors  
open. This will result in a reduction  
in efficiency and hence heat output.  
The more reactive fuels, like  
homefire, wood and coal will burn  
better when the doors are open than  
fuels like phurnacite, sunbrite and  
ancit.  
The rate of burning and hence the  
output is controlled by the control  
knob on the left hand side of the  
appliance and the airwash control on  
the right, (see Figs. 1 & 2.) Use the  
control knob on the left to control the  
heat output from the fire and keep the

using solid fuel do not go beyond the  
45° position as this can cause the  
grate to jam.  
REFUELLING  
Keep the firebox well filled (the fuel  
may be sloped up from the front  
firebars), but do not allow fuel to  
spill over the top of the front fire  
bars. Take care, 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.  
If jamming does occur then the fire  
should be allowed to burn for  
approximately half an hour before  
riddling the grate again as described  
above.  
ASH CLEARANCE  
The ashpan must be emptied  
regularly before it becomes too full.  
The most convenient time to remove  
the ash is just before riddling the fire  
since the ash will then be at it’s  
coolest. Use the tool provided to  
remove the ashpan.  
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.  
OVERNIGHT  
BURNING  
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.  
Ensure that the air inlet damper is  
not prevented from closing by spilled  
fuel or ash.  
Empty the ashpan, if necessary, and  
then riddle the fire. If the fire is very  
low then it may be necessary to add a  
little fuel and turn the thermostat  
control up for a brief period until the  
fire is burning well before filling with  
fuel. When burning wood use large  
logs overnight as they will burn more  
slowly than small ones.  
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.  
Some experimentation may be  
necessary to find the setting most  
suitable for the particular fuel used  
and the draw on the chimney, but  
generally the thermostat should be  
turned down to the minimum setting  
and the airwash control nearly closed  
overnight.

When burning solid fuels riddling  
twice a day is usually sufficient.  
When burning wood or peat, ash  
should be allowed to build up and  
generally riddling every other day  
will be sufficient.  
For overnight burning the fire doors  
must be closed.  
Tool To Be

Solid Fuel  
To revive the fire, empty the ashpan  
if necessary, riddle (when burning  
solid fuel), and turn the thermostat  
control knob to maximum and open  
the airwash control. When the fire is  
burning well load on more fuel as  
necessary and set the thermostat and  
airwash controls to the desired  
setting.  
The fire should be riddled with all  
doors shut. Place the tool on the knob  
and rotate between the horizontal and  
the 45° position several times as  
shown in Fig. 3.  
Fig. 3. Grate Operation  
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 or peat).  
When burning wood or peat do not  
riddle all the ash into the ashpan,  
keep a layer about 12 mm (1/2 inch)  
thick on the grate.  
When burning wood do not riddle but  
simply set the air controls to  
maximum until the fire picks up and  
then set them at the desired setting  
and refuel as necessary.

THROAT PLATE AND  
FLUEWAY CLEANING  
CLEANING AND  
MAINTENANCE  
CHIMNEY SWEEPING  
The chimney should be swept at least  
twice a year. In most installations it  
will be possible to sweep the chimney  
through the appliance.  
It is important that the throat plate  
and all the appliance 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.  
The appliance is finished in vitreous  
enamel. To clean the surfaces simply  
wipe over with a dry cloth. Abrasive  
pads and scouring cleaners must not  
be used as these will damage the  
finish. Care should be taken not to  
knock the enamel with hard objects  
as it will chip.  
First remove the front firebars and  
the throat plate. Then sweep the  
chimney ensuring that soot is  
removed from all horizontal surfaces  
after sweeping.  
The throat plate and flueways may be  
cleaned with a low fire still burning.  
Use the scraper tool to scrape any  
sooty deposits to the front of the plate  
until they fall off into the fire.  
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 may be removed  
with a proprietary stove glass cleaner  
or ceramic hob cleaner. Some  
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 appliance to the  
chimney must be cleaned with a flue  
brush.  
More soot will be deposited on the  
throat plate and in the flueways if the  
appliance is run at low levels for long  
periods. If this is the case then more  
frequent cleaning will be necessary.  
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.  
Aerosol spray cleaners should not be  
used near the appliance whilst it is  
under fire.  
After clearing any soot from within  
the fire, replace the throat plate and  
the front firebars.  
SPECIAL POINTS  
WHEN BURNING  
COAL  
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.  
When burning housecoal keep the  
airwash control at least slightly open  
all the time (refer to Fig 2.).  
When loading the appliance 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.  
If the fire is going to be out of use for  
a long period (for instance in the  
summer) then to prevent condensa-  
tion, and hence corrosion, the  
thermostat should be left at the  
maximum setting and the main doors  
left ajar. It is also advisable to sweep  
the chimney and clean out the fire.  
TROUBLE SHOOTING  
Fire Will Not Burn.  
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.  
After long periods where the fire has  
been out of use, the chimney and  
appliance flueways should be cleaned  
before lighting.  
Check that:  
a) the air inlet is not obstructed in  
any way,  
b) that chimneys and flueways are  
clear,  
c) that a suitable fuel is being used,  
d) that there is an adequate air supply  
into the room,  
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, daily  
cleaning is recommended.  
For the fire to operate correctly it is  
important that the door seals are in  
good condition. Check that they do  
not become worn or frayed and  
replace them when necessary.  
e) that an extractor fan is not fitted in  
the same room as the fire.

should cause the chimney fire to go  
out in which case the control should  
be kept at the minimum setting until  
the fire in the appliance has gone out.  
The chimney and flueways should  
then be cleaned. If the chimney fire  
does not go out when the above  
Fire Blazing Out Of  
Control.  
Check that:  
Door Glass Blacks Up  
a) the doors are tightly closed,  
b) the thermostat knob is turned  
down to the minimum setting,  
c) the air inlet damper is closed (at  
the bottom left of the appliance), and  
that it is not prevented from closing  
completely by a piece of ash,  
d) a suitable fuel is being used,  
e) the door seals are in good  
condition.  
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 turning the  
thermostat down. This may also be  
necessary when re-fuelling the stove.  
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.  
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.  
Over-Firing  
If the fire is over-fired it will cause  
premature failure of the internal fire  
parts. Overfiring is occurring when  
any internal 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,  
c) Never completely close the airwash  
control - as a guide it should be at  
least a quarter open.  
b) the thermostat on the fire is  
working correctly,  
c) a suitable fuel is being used.  
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. It is  
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.  
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:  
Freezing  
A) Open doors and windows to  
ventilate the room.  
B) Let the fire out and safely dispose  
of fuel from the appliance.  
If a boiler is fitted do not light the  
fire if there is any possibility that any  
parts of the system may be frozen.  
C) Check for flue or chimney  
blockage, and clean if required.  
D) Do not attempt to relight fire until  
cause of fume has been identified, if  
necessary seek professional advice.  
Chimney Fires.  
If the chimney is thoroughly and  
regularly swept, chimney fires should  
not occur. However, if a chimney fire  
does occur turn the control knob to  
the minimum setting, and tightly  
close the doors of the appliance. This

together. Enough water should be  
added so that no more than one or  
two drops of water are released when  
a handful of the mixture is squeezed.  
The end of the flue pipe must line up  
with the centre-line of the chimney,  
and must also extend to the point  
where the chimney narrows to its  
final size. Any large voids must be  
filled and flaunched to the flue pipe

operation of the appliance.  
Replace the back fireplate, the side  
fireplates, the front firebar and the  
throat plate.  
After filling with vermiculite flaunch  
the top of the flue connector pipe to  
the chimney with lime mortar.  
Ensure that the flue pipe is well  
sealed to the chimney.  
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.  
Make good the hole(s) in the
