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 stove is not suitable for use in a shared

flue system.

Your Island stove has been designed to work with the minimum

effort. If any operation - such as riddling the grate or opening and

closing the doors - begins to require extra force then the cause must

be investigated and corrected to prevent damage being caused to the

stove.

Remember that the stove will be hot and that it is made from hard

materials - ensure that you have a good balance before operating the

fire.
This stove is capable of intermittent or continuous operation.

F U E L

This stove is intended primarily for burning wood. 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 woods

(such as Ash, Beech and Oak) are better than soft woods (such as

Pine and Spruce.) 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.

1) In the open 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 closed 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 closed position ash is able to build up on the grate

as is necessary for effective wood 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

The door handle has been carefully designed so that in normal use it

may be operated using bare hands. However, if you need to open the

doors when the fire is running at maximum then the use of a cloth or

glove may be required.

Take care not to touch the doors as they will be hot when the fire is

burning. Turn the door handle clockwise to open, and anti-clockwise

to close. The stove is normally run with the doors shut.

M U LT I G R A T E

Your Charnwood Island is fitted with a multi grate to enable wood to

be burned and ash to be cleared. The grate has two positions:-

open position by moving the tool up until the handle is in the 1

o'clock position. The grate is put into the closed position by moving

the tool down until the handle is in the 5 o'clock position. To riddle

the appliance the tool should be moved between the 1 o'clock and 3

o'clock positions several times. When burning wood the ash should

be allowed to build up and riddling should only be carried out once

or twice a week.

L I G H T I N G

Light the Stove using dry kindling wood and paper or fire lighters. Set

the grate into either the closed position or the open position as

required. Place the paper, or fire lighters, and kindling on the grate

and cover with a few small dry logs. Open the thermostat control

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

R I D D L I N G

When burning wood, ash should be allowed to build up and only

riddled when the ash begins to cover the slots in the rear fireplate.

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. After riddling, the grate should be put back into the open

or closed position as required (the tool should be in the 1 o'clock

position for open grate or in the 5 o'clock position for closed grate).

to become hot before adjusting thethermostat 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.

At first only light a small fire and burn it slowly for two hours to allow

any residual moisture in the bricks to evaporate.

When relighting the stove, riddle slightly and then empty the ashpan.

C O N T R O L L I N G T H E F I R E

The fire is controlled by the water temperature thermostat. The

water temperature is set by the control knob shown in Fig. 1. Turn

the knob clockwise to increase the water temperature or anti-

clockwise to decrease.

This thermostat controls both primary and secondary air, enabling

just one control to be used. The balance between primary and

secondary air for particular flue conditions is pre-set using the sliding

control mounted on the thermostat box beneath the stove. Once set

this should not need to be adjusted.

R E F U E L L I N G

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

spilling over the top of the front fire bar. Logs should be evenly

distributed, filling the firebed to give the most pleasing flame pattern

Care should be taken especially when burning wood that fuel does

not project over the front fire bar or damage to the glass may be

caused when the doors are closed, it can also cause the glass to black

up . Maximium filling height is such that logs cannot fall from the fire

when the doors are opened. Liquid fuels are not to be used on this

appliance.

A S H C L E A R A N C E

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.

For overnight burning the fire doors must be closed. Use large logs

rather than small ones.

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. 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, add some small logs and open the thermostat

control to maximum. When the fire is burning well load on more fuel

as necessary and move the thermostat control to the desired setting.

D o o r Se al s

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.

S P E C I A L P O I N T S W H E N

B U R N I N G W O O D

The grate should be kept in the closed 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 sides or back 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 lighting the fire a few small

dry logs with a good amount of kindling will help to get the fire up to

temperature quickly.

M A I N T E N A N C E

C l e a ni ng

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 then special high temperature paints are

available from your supplier or from Charnwood.

C l e a ni ng th e G la ss

The glass in the doors is a special ceramic glass which is able to

withstand high temperatures. Before cleaning the glass open the

doors and allow them to cool. Clean the glass using a damp cloth and

then wipe 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. Aerosol spray cleaners should

not be used near the appliance whilst it is under fire.

W h e n No t in U s e

If the fire is going to be out of use for a long period (for instance in

the summer) then to prevent condensation, and hence corrosion, the

air control should be left fully open and the fire doors left ajar. It is

also advisable to sweep the chimney and clean out the fire. Spraying

the inside of the doors and firebox with a light oil, such as WD40,

will also help to keep all internal parts working well.

After long periods where the fire has been out of use, the chimney

and appliance flueways should be cleaned before lighting.

Page 5

S e r vici n g

It is recommended that the fire is serviced once a year to keep it in

first class working order. After cleaning out the firebox thoroughly,

check that all internal parts are in good working order, replacing any

parts that are beginning to show signs of wear. Check that the doors

seals are in good condition and that the doors seal correctly. A

servicing guide is available on request. Repairs or modifications may

only be carried out by the Manufacturer or their approved agents.

Use only genuine Charnwood replacement parts.

T H R O A T P L AT E A N D F L U E WAY

C L E A N I N G

It is important that the throat plate and all the stove flueways are kept

clean. They should be checked approximately once a week, by

looking up into the firebox for signs of soot or fly-ash on the throat

plate and at the sides of the firebox. If there are signs of a build up of

soot or fly-ash deposits then the fire must be let out in order to clean

the throat plate and flueways.

Before attempting to clean the throat plate and flueways ensure that

the fire is cold. Wear suitable gloves to prevent irritation from soot

deposits. To remove the throat plate lift the whole plate up until it

comes clear of the rear brackets, then swing the back edge forwards

and unhook(see Fig. 4.).

C H I M N E Y S W E E P I N G

The chimney should be swept at least once a year. Where a top

outlet is used it will generally be possible to sweep the chimney

through the appliance.

First remove the front firebar, side fire plates, 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. 4), the side fireplates, and front firebar .

Different types of sweep's brushes are available to suit different

flueways. For standard brick chimneys a wire centre sweep's brush
