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-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 C)! 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 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 200mm .

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.

i

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

• Starting from the flue spigot, the flue must run as vertically as possible. Changes in direction and horizontal pieces disrupt the outward flow of comFor good combustion, the stove needs air (oxygen). combustion gases and may cause soot deposits. This air is supplied via adjustable air inlets from the To prevent combustion gases from cooling down area in which the stove is installed.

• To prevent combustion, guess from cooling down too much, which reduces the draught, ensure that The combustion will be incomplete in case of the interior diameter is not too big. insufficient ventilation, which results in toxic

The flue or chimney should ideally have the same gases being produced and spread through the diameter as the connection collar.

For the nominal diameter: see the appendix As a rule of thumb, the air supply should be "Technical data". If the smoke channel is well 5.5cm^2/kW . Extra ventilation is needed when:

insulated, the diameter may be slightly bigger. The stove is in an area that is well-insulated. (up to 2x the section of the connection collar).

The section (area ) of the smoke channel must be constant. Wider segments and (in particular) narrower segments disrupt the outward flow of combustion gases. You can provide extra ventilation by having a ven
When using a cover plate or exhaust hood : make sure that the cover does not restrict the flue out. Take 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
The flue must end in a zone that is not affected by 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: 60cm above the ridge of thence, see the appendix "Technical data".
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.
The floor on which the appliance is placed must have sufficient bearing capacity. For the weight of the appli
Hence, 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".

Floors and walls

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 in fit 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".

Preparation

Please check the appliance for damage caused during transport or any damage or defects immediately after delivery.

If you detect damage caused during transport or any other damage or defects, do not use the appliance and notify the supplier.

remove the detachable parts (vermiculite interior plates, baffle plate) from the appliance before you call it.

By removing removable parts, it is easier to move the appliance and to avoid damage.

Note the location of the removable parts, so that you can re-position the parts in the correct place later on.

Removing inner plates

Vermiculite inner plates are light and tend to be ochrous in colour on delivery. They insulate the combustion chamber to boost combustion. Cast iron inner plates protect the combustion chamber and dissipate heat to the surroundings.

1. Slide the inner plate at the top of the appliance forwards (1); see following figure.

1. Push the plate upwards so that you can tip it diagonally (2).
2. Lower the plate to the bottom in the space (3).
3. Remove the plate from the appliance using the door (4).
4. Repeat instructions (1) to (4) for the two remaining plates.

Sides of inner plates

1. For both sides, slide the front inner plate forwards as far as possible (1); see following figure.

1. Detach the baffle plate at the back by unscrewing the M8 screw (13mm) (2).
2. Lift up the baffle plate from the back.
3. Tip and lower the baffle plate (3).
4. Remove the plate from the appliance using the door (4).

Mounting the legs and ash drawer

Fit the legs to the appliance; see the following figure.

1. Push the second plate up a bit (2) and tip it diagonally (3) and (4).
2. Remove the plate from the appliance through the door (5).
3. Remove the third plate in the same way as the second one by repeating instructions (2) and (3).
4. Slide the first plate into the position of the second plate and remove it in the same way.

Baffle plate (chimney pipe plate)

1. Take off the back cover (1); see following figure. You now have access to the combustion area from above.

1. Tip the stove from the side.

2. Fit the four legs on the bottom plate using the washers and the M8 nuts that are found on the bottom plate.

3. Mount the ash drawer under the bottom plate below the door using the M8x12 screws

4. Set the appliance upright on the mounted legs.

Support the appliance when placing it upright to the flue from the the side, upper side or the rear. so that not all the weight is not on the legs.

Mounting the handle and operating knob

Secure the handle using the M6x20 screw supplied(2) to the front piece and the operating knob for the air regulator (1); see following figure. 4

Connecting to the side, upper side or the rear

First of all, choose whether to connect the appliance to the flue from the the side, upper side or the rear.

1. Mount the sealing collar (300-8) on the flue opening with the two screws and M8 nuts; see following figure.
2. Apply sufficient sealant to the seal (300-7).
3. Close off the other connection options with the (2) sealing covers and clamping plates supplied using air M6 screws.
4. Use enough sealant

Preparing the connection to the flue

When connecting the appliance to the chimney you have the choice of connecting via either the side, the rear or the upper side. See the paragraph 'Connect to the side, upper side or rear'. It is also possible to make a connection using the 400-200 attachment that can be ordered separately; see the paragraph 'Connecting using attachments'.

Connecting using attachments

The 400 and 200 attachments increase the heat exchange area of the stove thereby making it more efficient. By using the optional attachments (sold separately), you can make side and upper connections.

Sealant and materials supplied.

Follow the instructions given in the paragraph 'Connecting to the side, upper side or rear' section to create the flue opening and to mount the collar connection supplied.

Installing and connecting

1. Position the stove in the correct place, and make sure it is level.
2. Connect the stove to the fuel hermetically.
3. Re-position all removed parts in the correct places in the stove.

Never use the appliance without the ver-miculite 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 the stove is located.

Fuel

This stove is only suitable for burning natural wood, sawn and chopped wood that is sufficiently dry.

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 place a firelighter cube in the lower layer of kind-pollute the environment and because they heavily soil ling and light the cube according to the instructions the appliance and flue, which may lead to a chimney on the packaging.

You can check whether the flue has sufficient draught by lighting a ball of paper above the baffle plate. A cold 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.

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.

1. Close the appliance door and completely open the compact stacking air slider in the door.
2. 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

After you have followed the instructions for lighting :

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.

Open stacking

If the logs are stacked openly, the wood will burn quickly as the oxygen can reach each log easily. If you want to use the stove for a short while, make open stack.

If the logs are stacked tightly, the wood will burn more slowly as the oxygen can only reach some logs easily. If you want to burn wood for a longer period, make a compact stack.

1. Close the door of the appliance.
2. Control the fire with the air slider in the door.

Fill the appliance half-way at most.

Controlling combustion air

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

The main air vent (1) regulates the fire.

The baffle plate has permanent vents (2) that allow afterburning.

Advice

Never burn wood with an open door.

Stoke the fire regularly and thoroughly.

stances 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 ash

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.

The flow of air through the fire plate must not be obstructed, however, and no ash may be allowed to accumulate behind a vermiculite inner plate. Remove the excess ash regularly.

You can remove the excess ash with the aid of a small shovel.

Fog and mist

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.

If you frequently burn at a low setting, tar and creosote may be deposited in the flue. Tar are creosote are highly combustible substances.

Thicker layers of these substances may catchRefer to the appendix "Diagnostic diagram" to resolve fire if the temperature in the chimney increases any problems in using the stove.

Always open the door carefully.
- Close the door immediately after adding fuel.
- Topping up with a few logs regularly is better than adding many logs in one go.

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.

Checking fire-resistant inner plates

The fire-resistant inner plates are consumables and subject to wear. 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.

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.
