Make sure there is sufficient protection if young children, disabled persons or old people are in the vicinity of the appliance.

Safety distances from flammable materials must be adhered to strictly.

Don't place any curtains, clothes, laundry or other combustible materials on or near the appliance.

Don't use flammable or explosive substances near the appliance when it is in use.

Avoid a chimney fire by having the chimney swept regularly. Never burn wood with the do open.

In the case of a chimney fire: close all air in of the appliance and alert the fire brigade.

If the glass in the appliance is broken or cracked, it must be replaced before you can use the appliance again.

Make sure there is adequate ventilation in the room where the appliance is installed. If ventilation is insufficient, combustion will be incomplete resulting in toxic gases being produced and spread through the room. See the chapter "Installation requirements" for more information on ventilation.

Installation requirements

General

The appliance must be connected tightly to a well-by functioning chimney.

For the connection measurements: see the appendix "Technical data".

Ask the fire brigade and/or your insurance company about any specific requirements and regulations.

Chimney (flue)

The flue or chimney is needed for:

▶ Removal of combustion gases via natural draught.

As the warm air in the flue or chimney is lighter than the outside air, it rises.

Air intake, needed for the combustion of fuel in the appliance.

A poorly-functioning flue or chimney can cause smoke to escape into the room when the door is opened. Damage caused by smoke emissions into the room is poor not covered by the warranty.

Do not connect multiple appliances (such as a boiler for central heating) to the same flue, unless local or national regulations allow this. In the event of two connections ensure that the difference in height between the connections is no less than 200 mm.

Ask your installer for advice regarding the flue. Refer to the European norm EN13384 for a correct calculations for the flue.

The flue must satisfy the following requirements:

The flue or chimney must be made of fire-resistant material, preferably ceramics or stainless steel.

The flue or chimney must be airtight and well-cleaned and guarantee sufficient draught.

A draught/vacuum of 15 - 20 Pa during normal operation is ideal.

Starting from the flue spigot, the flue must run a vertically as possible. Changes in direction and horizontal pieces disrupt the outward flow of combustion gases and may cause soot deposits.

To prevent combustion gases from cooling down For good combustion, the stove needs air (oxygen). too much, which reduces the draught, ensure that this air is supplied via adjustable air inlets from the interior diameter is not too big. area in which the stove is installed.

The flue or chimney should ideally have the same ⚠️ The combustion will be incomplete in case of diameter as the connection collar. insufficient ventilation, which results in toxic

insulated, the diameter may be slightly bigger As a rule of thumb, the air supply should be 5, (up to 2x the section of the connection collar) cm²/kW. Extra ventilation is needed when:

The section (area) of the smoke channel must constant. Wider segments and (in particular) narrower segments disrupt the outward flow of combustion gases.

When using a cover plate or exhaust hood : make sure that the cover does not restrict the flue outlet and that the cap does not impede the outward flue ventilation louvre fitted on the outside wall. of combustion gases.

The flue must end in a zone that is not affected surrounding buildings, trees or other obstacles.

The flue outside the house must be insulated.

The chimney must be at least 4 metres high.

As a rule of thumb: 60 cm above the ridge of the roof.

If the ridge of the roof is more than 3 metres away from the flue: stick to the measurements in the following figure. A = the highest point of the roof within a distance of 3 metres.

be The stove is in an area that is well-insulated.

There is mechanical ventilation, for example a central extraction system or an extraction hood in an open kitchen.

You can provide extra ventilation by having a ventilation louvre fitted on the outside wall.

Make sure that other air consuming appliances (such as tumble-driers, other heating appliances or a bathroom fan) have their own supply of outside air, or are switched off when you use the appliance.

You can also connect the appliance to an outside air supply. This makes additional ventilation unnecessary.

Floors and walls

The floor on which the appliance is placed must have sufficient bearing capacity. For the weight of the appliance, see the appendix "Technical data".

Protect flammable flooring from heat radiation by means of a fireproof protective plate. See the appendix "Distance from combustible material".

Remove combustible material such as linoleum, carpets/rugs and similar materials below the fireproof protective plate.

Keep sufficient distance between the appliance and combustible materials such as wooden walls and furniture.

The connecting tube also radiates heat. Ensure that there is sufficient distance or a shield between the connecting tube and combustible material.

The rule of thumb for a single-walled tube is a distance of 3x the diameter. If a lining shell is fitted around the tube, a distance of 1x the diameter is permissible.

Carpets and rugs must be at least 80 cm away from the fire.

Use a fireproof floor plate to protect a flammable floor from any ash which may fall front of the stove. The protective plate must comply with national standards.

For the dimensions of the fireproof protective plate: see the appendix "Distance from combustible material".

For further requirements in connection with fire safety: see the appendix "Distance from combustible material".

Preparing the outside air connection

If the appliance is installed in a room without sufficient ventilation, you can install a connecting kit on the appliance for the outside air supply. Some of the air inlets on the appliance must then be plugged with the blanking material provided. We recommend applying a connection set that has a valve you can close when the stove is not in use.

The air supply tube is 100 mm in diameter. If the tube is smooth, it may be no longer than 12 metres. If accessories such as bends are used, the maximum

length (12 m) must be reduced by 1 m for each accessory used.

1. Close the air inlet in the bottom plate with the small cast-iron cover plates (1) and screws (2); see following figure.

By closing the air inlet in the bottom plate you prevent air being used for combustion from an insufficiently ventilated space.

2. Connect the appliance airtight to the flue (chimney).

3. In the case of connection to outside air: connect the outside air supply to the connection collar within the base or log compartment of the stove or to the fitted elbow.

4. Re-position all removed parts in the correct places in the stove.

Never light a fire in the appliance without the fireproof inner plates.

The appliance is now ready for use.

Use

First use

When you use the stove for the first time, make an intense fire and keep it going for a good few hours.

This will cure the heat-resistant paint finish. This may result in some smoke and odours. You could open windows and doors for a while in the area in which stove is located.

Fuel

The appliance is suitable for the burning of natural wood; sawn and chopped wood that is sufficiently dry.

The appliance is also suitable for the burning of brown coal briquettes and anthracite coal.

Do not use other fuels, as they can cause serious damage to the stove.

You are not allowed to use the following fuels, as they pollute the environment and because they heavily soil the appliance and flue, which may lead to a chimney fire:

▶ Treated wood, such as scrap wood, painted wood, impregnated wood, preserved wood, plywood and chipboard.

Plastics, scrap paper and domestic waste.

Wood

Hardwood, such as oak, beech, birch and fruit tree wood is the ideal fuel for your stove. This type of wood burns slowly with calm flames. Softwood contains more resins, burns faster and sparks more.

▶ Use seasoned wood that contains no more than 20% moisture. The wood should have been ct seasoned for at least 2 years.

Saw the wood to size and split it while it is still fresh. Fresh wood is easier to split, and split wood dries more easily. Store the wood under a roof where the wind has free access.

Do not use damp wood. Damp logs do not produce heat as all the energy is used in the evaporation of moisture. This will result in a lot of smoke and soot deposits on the stove door and in the chimney. The water vapour will condense in the stove and can leak away through chinks in the stove, causing black stains on the floor. It may also condense in the chimney and form creosote. Creosote is a highly flammable compound and may cause a chimney fire.

Brown coal briquettes

Brown coal briquettes have approximately the same burning characteristics as wood.

▶ Ensure there is a good charcoal bed before you start burning brown coal briquettes.

For lighting the fireplace, follow the instructions in the "Lighting" paragraph.

Anthracite coal

Anthracite coal is categorised on the basis of properties, sometimes prescribed by law, such as the percentage of volatile substances. The ash content of anthracite coal is between 3% and 13%. The lower the ash content, the higher the net heating value and the less often you have to remove ash.

the appliance; see 'Controlling air combustion'.

1. Allow the fire develop into a good blaze until there is glowing bed of charcoal. You can then add fuel and adjust the appliance, see the chapter "Stoking with wood".

Burning wood

▶ Preferably use category A anthracite coal with a After you have followed the instructions for lighting : low ash content.

▶ Use the recommended size 12/22 or 20/30.

For lighting the fireplace, follow the instructions in the "Lighting" paragraph.

1. Slowly open the stove door.
2. Spread the charcoal evenly across the bottom of the stove base.
3. Stack a few logs on the charcoal.

Lighting

You can check whether the flue has sufficient draugh by lighting a ball of paper above the baffle plate. A flue often has insufficient draught and consequently, some smoke may escape into the room instead of up the chimney. You can avoid this problem by lighting the fire as described below.

1. Stack two layers of medium sized logs crosswise.
2. Stack two layers of kindling crosswise on top of the logs.
3. Place a firelighter cube in the lower layer of kindling and light the cube according to the instructions on the packaging.

Open stacking

1. Close the door of the appliance.

2. Close the primary air inlet and leave the secondary air inlet open. 4.

Fill the appliance up to one third capacity.

Burning brown coal briquettes

Brown coal briquettes burn in almost the same way wood. Using the primary air inlet, ensure sufficient supply of air under the fire. For further information the paragraph "Burning wood".

Burning brown coal briquettes creates a lot of ash. Regularly remove excess ash. See the paragraph "Removing ashes" for instructions.

For the properties and use of brown coal briquettes: consult your brown coal briquettes supplier or see the brown coal briquettes' packaging.

1. Slowly open the stove door.
2. Spread the charcoal evenly across the bottom of the stove base.

3. Spread a shovelful of coal on the charcoal bed and wait with the next shovelful until the coals start to glow.

4. Now add more coal.

Be careful not to smother the fire by adding too much coal at once.

You have added as much as you can once the glow of the previous load is only just visible.

1. Close the door.

2. Allow the coals to burn well for a few minutes and control the air supply using the primary air slider.

If the fire basket or the cast-iron plates start to glow red you have overfed the fire.

1. Regularly remove ashes from the stove base riddling the grate. Use the cold handle to operate the riddling rod.

After you have followed the instructions for lighting:

Controlling combustion air

The appliance has various features for air control; see following figure.

Advice

⚠️ Never burn wood with an open door.
Regularly burn wood with intense roaring fires.

If you frequently have low intensity fires, tar and creosote may be deposited in the chimney

. Tar and creosote are highly combustible substances. Thicker layers of these

substances may catch fire if the temperature in Use the riddling rod to free the grate of excess the chimney increases suddenly. By allowing ashes.

the fire to burn very intensely regularly, layers of tar and creosote will disappear.

Low intensity fires also cause tar deposits on the stove window and door.

When the outside temperature is not very low, it is better to burn wood intensely for a few hours instead of having a low intensity fire for long period of time.

If the appliance is still warm, use the "cold hand" to operate the riddling rod.

▶ Control the air supply with the secondary air inlet

The secondary air inlet not only supplies air to the fire but to the glass as well, so that it does not quickly become dirty.

Open the primary air inlet for the time being if the air supply by the secondary air inlet is inadequate or if you want to fan the fire. 2. Op

It is better to add a small amount of logs regularly. Using the scraper, sweep the remaining ashes than to add many logs at the same time. through the grid.

Technical line drawing of a mechanical component with no visible text or symbols

Extinguishing the fire

1. Open the stove door.

aay Using the scraper, sweep the remaining ashes through the grid.

Do not add fuel and just let the fire go out. If a fire is damped down by reducing the air supply, harmful substances will be released. For this reason, the fire should be allowed to go out naturally. Keep an eye on the fire until it has gone out. All air inlets can be closed once the fire has died completely.

Removing ashes

After the wood has been burnt, a relatively small amount of ashes is left over. This bed of ashes is a good insulating layer for the stove base plate and improves combustion. It is good to leave a thin layer of ashes on the stove base plate.

1. Remove the ashtray (see next figure) using the glove provided and empty the ashtray.

The flow of air through the fire plate must not be obstructed, however, and no ash may be allowed to5. Replace the ash pan and close the stove door. accumulate behind a cast-iron inner plate. Remove the excess ash regularly. Fog and mist

After the brown coal briquettes and anthracite coal has been burnt, a relatively large amount of ash is over. No ash may be allowed to accumulate underneath the fire grate and the ash should never reach the bottom of the grate. This will cause the grate to overheat and be damaged. Fog and mist hinder the flow of flue gases through the flue. Smoke can blow back and cause a stench. If it is not strictly necessary, it is better not to use the stove in foggy and misty weather.

problems

Refer to the appendix "Diagnostic diagram" to resol any problems in using the stove.

To reach the nominal output, approximately 2 kg of fuel needs to be burnt every 45 minutes

Remove and install baffle plate

Unscrew the clamping plate on the front of the baffle plate. Lift the baffle plate from the support and tilt the baffle plate out of the appliance. Please ensure that the rear of the baffle plate properly connects to the air tunnel at the back of the appliance when reinstalling.

Maintenance

Follow the maintenance instructions in this chapter to keep the stove in good condition.

Chimney

In many countries, you are required by law to have your chimney checked and maintained.

At the beginning of the heating season: have the chimney swept by an expert.
During the heating season and after the chimney has not been used for a long time: have the chimney checked for soot deposits.
▶ After the heating season: seal off the chimney with a ball of paper.

Cleaning and other regular maintenance activities

Do not clean the stove when it is still warm!

Clean the exterior of the stove with a dry lint-free cloth.

You can clean the stove interior thoroughly at the end of the heating season:

If necessary, first remove the fire-resistant inner plates. See the chapter "Installation" for instructions on removing and installing the inner plates.
If necessary, clean the air supply ducts. Remove the top plate to this end. The top plate lies loosely on the appliance.
If required, remove the baffle plate at the top of the appliance and clean it.

Checking fire-resistant inner plates

The fire-resistant inner plates are consumables and subject to wear. Vermiculite inner plates are fragile. Do not knock the inner plates with logs. Check the fire-resistant inner plates frequently and replace them when necessary.

See the chapter "Installation" for instructions on removing and installing the inner plates.

The insulating vermiculite or chamotte inner plates may develop hairline cracks, but this does not affect their performance adversely.

Cast-iron inner plates last a long time if you remove frequently the ash that can accumulate behind them. If accumulated ash behind the cast-iron plate is not removed, the plate will no longer be able to dissipate the heat to the surroundings and this may cause the plate to warp or crack.

Never use the stove without the fire-resistant inner plates.

Cleaning glass

Dirt clings less easily to well-cleaned glass. Proceed as follows:

1. Remove dust and loose soot with a dry cloth.

2. Clean the glass with stove glass cleaner:

a. Apply stove glass cleaner to a kitchen sponge, rub down the entire glass surface and give the cleaning agent time to react.

b. Remove the dirt with a moist cloth or kitchen tissue.

1. Clean the glass again with a normal glass cleaning product.

2. Rub the glass clean with a dry cloth or kitchen tissue.

Do not use abrasive or aggressive products to clean the glass.

▶ Wear household gloves to protect your hands.

If the glass in the appliance is broken or cracked, it must be replaced before you can use the appliance again.

Make sure that no stove window cleaner runs between the glass and the cast-iron door.

Lubrication

Although cast-iron is slightly self-lubricating, you will still need to lubricate moving parts frequently.

Lubricate the moving parts (such as guide systems, hinge pins, latches and air slides) with heat resistant grease that is available in the specialist trade.

Touching-up the paint finish

Small areas of damaged paint finish can be touched-up with a spray can of special heat-resistant paint, available from your supplier.

Areas of damaged enamel can be touched up with a special heat-resistant paint finish that is available from your supplier.

Checking the seal

▶ Check whether the door sealing rope is still in good condition and works well. The sealing rope is subject to wear and will need to be replaced over time.

Check the appliance for air leaks. Close any chinks with stove sealant.

Allow the sealant to harden fully before lighting the stove, as any moisture in the sealant will form bubbles, resulting in a new air leak.

					Problem
●					Wood will not stay lit
	●				Gives off insufficient heat
		●			Smoke emissions into the room when adding wood
			●		Fire in stove is too intense, is hard to adjust
				●	Deposit on the glass
					Possible cause Possible	solution
●	●	●		●	Insufficient draught	A cold flue usually failsto create sufficient draught. Follow the instructions for lighting in the "Use" chapter; open a window.
●	●	●		●	Wood too damp Use wood with no more than 20%moisture.
●	●	●		●	Logs too large	Use small piecesof kindling. Use split logs no larger than 30 cm in circumference.
●	●	●	●	●	Wood stacked incorrectly	Stackthe logs in a way that allows adequate air flow between the logs (open stacking, see "Burning wood")
●	●	●		●	Chimney does not work properly	Check whether the chimney meets the requirements: at least 4 metres high, right diameter, well insulated, smooth inside, not too many bends, no obstructions in chimney (bird'snest, too much soot deposit), hermetically tight (no chinks).
●	●	●		●	Chimney stack incorrect Sufficiently high above the roof, no obstacles in the vicinity
●	●	●	●	●	Air inlets set incorrectly Open the air	inlets completely.
●	●	●		●	Stove connected to the chimney incorrectly	Connection should be hermetically tight.
●	●	●		●	Vacuum in area in which the stove is installed	Switch off extraction systems.
●	●	●		●	Insufficient supply of fresh air	Provide an adequate air supply; if necessary use outside air connection.
●	●	●		●	Adverse weather conditions? Inversion (reversed air flow in chimney because of a high outside temperature) if required, installan extra hood on the flue to increase the draught. extreme wind speeds	We recommend you don't use the appliance in the case of inversion.
		●			Draught in the living room	Avoid draught in the living room, do not place the appliance near a door or heating air ducts.
				●	Flames touch the glass	Make sure the wood is not positioned too close to the glass. Slide the primary air inlet cover closer to the "Closed" position.
			●		Stove is leaking air Check the door seals and stove joints.
