Take care not to touch the door as it will be hot when the fire is

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

to close.

REC IPRO C ATING GR ATE

Your Charnwood Cove is fitted with a reciprocating grate to enable

wood to be burned and ash to be cleared. The grate has two

positions:

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 door opening tool supplied as shown in Fig. 2. The grate is

put into the 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. To riddle the appliance the tool should be

moved between the lower and horizontal 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.

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 Cove stove has been designed to work with the minimum

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

closing the door - 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 is made from hard

material. Ensure that you have good balance before operating the

fire.

When using the stove in situations where children, aged and/or

infirm persons are present a fireguard must be used to prevent

accidental contact with the stove. The fireguard should be

manufactured in accordance with BS 8423:2002.

This stove is capable of intermittent operation.

FUE L

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.

PETROLEUM COKE IS NOT SUITABLE FOR USE ON THIS

APPLIANCE. ITS USE WILL INVALIDATE THE GUARANTEE.

This stove is not designed to burn household waste. For advice on

other fuels, please contact Charnwood.

Approximate suitable log sizes are:

Cove 2 370mm(15in) long and 75mm (3in) diameter

Cove 3 500mm(20in) long and 75mm (3in) diameter.

Log moisture content of <20% is recommended.

DOO R OPERATI ON

The door handle has been carefully designed to be removed from

the stove during normal operation and re-fitted prior to loading and

de-ashing. However, if you need to open the door when the fire is

running at maximum then the additional use of a cloth or glove may

LIG HTING

The stove may be lit 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 air control

fully (see Fig. 1). Light the paper or fire lighters. Close the door 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.

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.

CON TROL LING TH E FIRE

The fire is controlled by the single air control knob shown in Fig. 1

TM

This unique QuattroFlow air control* provides carefully balanced

primary, secondary, tertiary and bypass air to enable optimum

burning conditions without the need to fiddle with multiple controls.

The rate of burning and hence the output is controlled by the air

control

Open the air control fully (boost position) when lighting or when

rapid burning is required. It should not be left fully open for long

periods as this can cause over-firing or excessive smoke production.

For high output move the air control to the high output position or

for low burning to the fully closed position. (see Fig.1).

When the fire is burning normally the air control gives enough

airwash to keep the glass clean. However, it will not always be

possible to keep the glass clean with the air control fully closed. For

correct firing we recommend the use of a stove pipe thermometer

which may be purchased from your supplier or from Charnwood.

The Cove 2 blu is fitted with an air control stop for use in a smoke

control area. This stops the stove from burning too slowly.

REF UELLI NG

Keep the firebox well filled but do not allow fuel to spill over the top

of the fuel retainer.

Logs should be evenly distributed, filling the firebed to give the most

pleasing flame pattern. The air control must be fully opened after

refuelling until the flames are established above the fire. It is best to

refuel on to a hot bed of embers. If at this point the fire starts to die,

the door must be cracked open until the fire is revived. If the fire has

started to die down before refuelling, then more kindling wood must

be added, the air control opened fully and the door cracked open to

re-establish the firebed before adding larger logs (see suitable log

sizes in Fuel section). This will avoid excessive smoke emission.

Care should be taken, especially when burning wood, that fuel does

not project over the fuel retainer or damage to the glass may be

caused when the door is closed. It can also cause the glass to blacken

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

when the door is opened.

In smoke controlled areas do not fill the stove above the level of the

air holes in the back bricks, as overloading can cause excess smoke.

Do not operate with the door left open except as directed by the

instructions as this can cause excessive smoke.

RIDDLING

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 door shut (see Fig. 2). Place the

tool onto the riddling lever and rotate between the lower and

horizontal 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 closed

position for burning wood.

ASH C LEARA NCE

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 Door Opening tool

and gloves provided. Ensure that the tool is fully engaged before

lifting (See Fig.3). When carrying the ashpan, it should be kept

horizontal and supported by the carrying handle to prevent it falling

off the tool. 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.

Special Points when Burning Wood

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.

MAI NTENA NCE

Cleaning

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 or soft brush when the stove is

cold. Should re-painting become necessary then special high

temperature paints are available from your supplier or from

Charnwood.

Cleaning the Glass

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

withstand high temperatures. Before cleaning the glass open the

door and allow it 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.

When Not in Use

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 door left ajar. It

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

Spraying the inside of the door 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.

Door Seals

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.

Servicing

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,
