Before fitting the riddling grate (Fig. 1) remove the fuel retainer and

the wood ash retainer. The wood ash retainer is not required when

the riddling grate is fitted.

Undo the nut on the riddling blanking hole using a 10mm spanner.

Remove the cover and spacing washer (ensure you keep these in a

safe place as you will need to replace them if the riddling grate is

removed).

Feed the riddler rod through the hole on the right hand side of the

stove, and slide one washer onto the rod, (if there is not sufficient

room to the right of the stove to do this then remove the riddler

knob , fit one washer over the rod and then slide the rod through the

hole from the inside of the stove.)

Feed the rod through the two side fireplates and slide the other

washer on to the rod so that the washers end up outside the two side

fireplates. With the side fireplates pushed together fit the retaining

clips so that the washers come inside the clips.

Slide the side fireplates apart so that they rest against the sides of the

firebox. Slot in the front and rear support plates.

Fit the grate plates into position through the front and rear grate

support plates, making sure they locate correctly onto the riddler

rod. Fit the fuel retainer. Slide the ashpan under the grate.

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.

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

materials – ensure that you have good balance before operating the

fire.

Do not use an aerosol spray on or near the stove when it is alight.

There is a risk of explosion or flash ignition of the spray.

The stove is suitable for intermittent operation.

This stove has been designated to burn 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. Approximate suitable log sizes

are 255mm (10in) long and 75mm (3in) diameter.

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.

This appliance has been approved by HETAS as an intermittent

operating appliance for burning dry seasoned wood logs only. HETAS

approval does not cover the use of other fuels either alone or mixed

with wood logs nor does it cover the instructions for use of other

fuels.

Tool required for fitting the riddling grate:

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.

LIG H TING

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 chimney to evaporate.

Light the stove using dry kindling wood and paper or fire lighters. Put

the paper, or fire lighters, and kindling in the firebox and cover with a

few small dry logs. Open the air controls – the primary air control in

the door and the airwash control - fully (see Fig. 2) Light the paper or

fire lighters. The door may be left cracked open for a few minutes to

assist the combustion and heat up the firebox more quickly. When

the kindling wood is well alight add a few more small logs, close the

doors but leave the air controls fully open. When the flames are

established around these logs, load the stove with the required fuel

load. Maintain the air controls at maximum at this stage. 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. During the lighting period, do not leave the stove

unattended.

When relighting the stove, leave the ash on the base if burning wood,

unless it is becoming too deep, in which case some of it may be

removed. If burning high ash content fuel, clear the grate and empty

the ashpan before relighting.

ASH C L EARAN CE

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

air control slider and the airwash control (see Fig. 2).

The front air control slider should only be used when lighting or

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

long periods as this can cause over-firing. For low burning it should be

closed.

The airwash control is used most of the time to control the burning

rate and to keep the glass clean. Fully extended gives full airwash for

faster burning and clean glass whereas fully closed gives low burning.

It will not be possible to keep the glass clean if this control is fully

closed, particularly immediately after refuelling.

When the stove is hot, these controls must only be operated using

the tool provided or a glove to avoid the danger of burned fingers.

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 controls 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 ash. If at this point the fire starts to die, the

doors 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 controls opened fully and the door cracked open to

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

sizes in Fuel section).

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 black

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

when the doors are opened. In smoke controlled areas do not fill the

stove above the level of the front firebars. Liquid fuels are not to be

used on this appliance.

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

For correct firing we

recommend the use of a stove pipe thermometer which may be

purchased from your supplier or from ourselves.
