OPERATING INSTRUCTIONS FOR THE

CHARNWOOD FIRECLASS

GENERAL POINTS

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.

WARNING Do not fit an extractor fan in the same room
as this appliance as this can cause emission of smoke and
fumes into the room.

If the stove is fitted in place of an open fire then the
chimney should be swept one month after installation to
clear any soot falls which may have occurred due to the
difference in combustion between the stove and the open
fire.

Fig. 1. shows the main parts of the fire and the
descriptions used throughout these instructions. If spare
parts are needed then please refer to the exploded
drawing at the end of these instructions to find the
relevant part numbers.

When using the stove in situations where children or
infirm people are present please use a fire guard to
prevent accidents. The fire guard should be manufactured
in accordance with BS 6539.

2’’ 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’’.

Wood

Only dry well seasoned wood should be burnt on this
appliance as burning wet unseasoned wood will give rise
to heavy tar deposits. 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.

Peat

Ensure that the peat is well dried before use. Burning wet
peat will give rise to heavy tar deposits and reduced
outputs.

PETROLEUM COKE IS NOT SUITABLE

FOR USE ON THIS APPLIANCE, ITS USE

FUELS

The following fuels may be burnt on this stove. Please
pay careful attention to the special points regarding 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 following smokeless fuels may be burnt on this
appliance:

Anthracite Stove Nuts,
Coalite,
Homefire,
Maxibrite,
Welsh Dry Steam Coal (Large Nuts).

Coal

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

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 alternative.

MULTIFUEL GRATE

Your Charnwood stove is fitted with a multifuel grate
which enables solid fuel, wood and peat to be burned
equally effectively.

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.

Movement of the grate from one position to the other is
effected using the tool supplied. The grate is put into the
wood position by moving the tool direction of the arrow
‘W’ (marked on the handle of the tool) until the tool is
vertical. The grate is put into the solid fuel position by
moving the tool in the direction of the arrow ‘C’ until the
tool is horizontal.

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.

Care should be taken to ensure that ash is cool before
emptying it into plastic liners or bins.

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. Open the air slide in the door
fully and light the paper or fire lighters. Close the door
and allow the fire to burn until the fuel is well ignited
then load with more fuel close the air slide in the door
and adjust the secondary air control to the required level.

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. In the meantime the room should be
kept well ventilated.

Before relighting the stove, riddle, remove any clinker
from the firebed and then empty the ashpan.

CONTROLLING THE FIRE

The fire has three air controls as shown in Fig. 1. The
slide in the door is for use when lighting the stove and
for boosting the fire. It is also used when burning
smokeless fuels or coal. To close it completely tighten
the knob. The secondary air controls are used for
controlling the fire in normal use - they also help to keep
the glass clear.

Always close the door tightly after replacing the ashpan.
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 ourselves.

RIDDLING

When burning wood or peat, ash should be allowed to
build up and generally riddling every other day will be
sufficient.

When burning solid fuels riddling twice a day is usually
sufficient.

The fire should be riddled with the door shut. Place the
tool on the knob and rotate between the horizontal and
the 45 degree position several times as shown in Fig. 2.

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 wood
or solid fuel position as required (the tool should be
vertical for wood or horizontal for solid fuel).

From time to time, particularly when burning coal or
smokeless fuels, the fire may benefit from being poked. It
will also be necessary to occasionally clear the ash from
the side plates onto the middle of the grate.

Due to variations between different installations a certain
amount of experimentation will be necessary to find the
most suitable setting for the controls. Generally you
should find that keeping the air slide on the door closed
and using the secondary air to control the fire will give
the most satisfactory results and keep the glass clear.

FAN OPERATION

There is a thermal cut out linked into the fan control.
This means that the fan will not operate until the stove
warms up. The fan is turned on and off at the mains
supply. To control the speed of the fan turn the knob on
the right hand side of the stove to give the desired
circulation. Turn the knob clockwise to increase or
anti-clockwise to decrease the circulation.

ASH CLEARANCE

The ashpan should be emptied regularly before it
becomes too full. The most convenient time to remove
the ash is just before riddling the stove since the ash will
then be at its coolest.

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.

REFUELLING

Keep the firebox well filled but do not overfill to prevent
fuel from spilling 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.

OVERNIGHT BURNING

Empty the ashpan, if necessary, and then riddle the fire if
you are burning solid fuel. If the fire is very low then it
may be necessary to add a little fuel and open the air
control for a brief period until the fire is burning brightly
before loading with fuel. When burning wood use large
logs overnight as they will burn more slowly than small
ones. Some experimentation may be necessary to find the
setting most suitable for the particular fuel used and the
draw on the chimney. The knob on the air slide in the
door may be tightened to close the slide completely. If
the secondary air controls are completely closed then
some blacking of the glass is likely to occur. They may
therefore be left slightly open in most cases.

To revive the fire, empty the ashpan if necessary, riddle,
(when burning solid fuel), and open the air controls.
When the fire is burning well load on more fuel as
