Regulations to be observed

• Local and building law regulations
• The stove must be installed by a professional and connected to the chimney. The specific national regulations for safe installation of the connector must be complied with. The connecting piece used must possess an opening for cleaning.
• The stove must be regularly checked by a professional.
• The stove has national technical approval from the Deutsches Institut für Bautechnik (DIBt) (German  Institute for Civil Engineering) for room-air independent operation.

Due to its general technical approval, the stove can be used simultaneously with an approved ventilation system without additional safety device.

Equipped with a self-closing combustion chamber door, the stove is approved to be connected to multi-flue chimneys provided that it operates with a room-air dependent combustion-air supply.
Room-air independent operation requires that the exhaust gases of the fireplace be discharged through a single-flue chimney or the exhaust duct of a single-flue air-exhaust chimney. Exhaust gases may also be discharged into multiflue exhaust gas systems if all connected fireplaces are part of the same utilisation unit/action range of the ventilation system. Individual differences can be discussed with your district master chimney sweep.

Chimney design

The chimney design is according to DIN EN 13384 -1 and -2 or to the specific national regulations.
The chimney must comply with the temperature class T400.

Necessary data

Closed operation with billet wood / wood briquettes:

• Nominal thermal output: 5,0 kW
• Waste air mass flow rate: 4,16 / 3,94 g/s
• Waste air temperature at connection duct: 300° / 336 °C
• Minimum delivery pressure at nominal thermal output: 12 Pa

Combustion air supply

Ambient air independent combustion air connection

By an ambient air independent operating mode, the combustion air must be added from outside through a leakproof line or through a supply duct in the chimney. Thus, speak with your district chimney sweep master. Due to energy saving reasons, the combustion air inlet should be able to be blocked if the stove is not being operated. This can occur through a shut-off valve in the combustion air line or through the air slide valves on the stove. If a shut-off valve is used, this must be clearly identified with CLOSED/OPEN.
Through the shutoff, it is avoided that heat is removed from the set-up room through the constant circulation of cold combustion air and cold combustion air lines may lead to an increased formation of condensation.

Attention:
The combustion air line may not be closed during operation!

In order to feed the combustion air to the stove externally via a pipe instead of from the room in which it is installed, it is possible to screw a Ø 125 mm combustion air pipe to the back of the stove or at the bottom. If the combustion air pipe installed is longer than 3 m, calculations will have to be carried out to verify an adequate supply of combustion air. At extremely low outdoor temperatures, condensation can occur on the combustion air duct. For this reason it must be insulated with a suitable insulating material. Observe the rules of the oven and air heating construction craft.
Use the Olsberg combustion air pipes with sealing lip.

Installing the stove

The floor on which the stove is installed must be even and horizontal. The stove may only be set up on sufficiently stable floors. If the load-bearing capacity is insufficient, suitable measures (e.g. plate for load distribution) must be taken to achieve this.

This plate (sheet metal or glass) also protects the floor. If the flooring or carpet is inflammable, a stable and noncombustible spark protection plate must be used. This must extend 50 cm to the front and 30 cm to each side beyond the edge of the combustion chamber opening. Under the stove no spark protection plate is required.

Assembly sequence

• If intended, install the OEC or OEC SMART1.

• Install the side cladding.

• The Ø150mm stovepipe connection can be installed at the top or rear. The stove is supplied ready for connection from above. If you wish to connect it at the rear, the following steps must be carried out to make the necessary modifications:

  • Break out the cover in the back panel.
  • Replace the connector sleeve and the sealing cover.
    Stove installed straight in the corner
    

• Decide where the stove is to be installed. There must be no objects made of combustible materials within a distance of 80 cm of the stove’s radiation area, measured from the combustion chamber’s inspection glass, nor may any be placed within this area subsequently. Depending on the installation position of the stove in front of walls that need to be protected (flammable or load-bearing), the following distances from walls need to be observed in accordance with the position of the combustion chamber door to the wall / side panel or the back panel (see schematic diagram). When not dealing with walls that need to be protected, you merely need to observe a minimum distance of  approx. 5 cm to allow for proper heat dissipation.

• Install the pipe lining (provided on site) in the chimney. The connection height can be individually specified for a top stovepipe connection, however should not exceed 1.5 m from the connector sleeve. For the rear stovepipe connection heights please refer the “Technical Data“ chapter. No combustible material is permitted within a radius of 20 cm around the stove pipe.

• Connect the stovepipe at both connection points with stove putty so that the stove pipe is permanently sealed.

• Push the stove onto its planned position and orient it so that the stovepipe fits into the pipe lining

The stovepipe connections must be tight. The stovepipe must not protrude into the chimney.
Bear in mind that on partition walls in accordance with test specification EN 13240 the temperature of 85°C can be reached, and with light wallpaper or similar combustible construction materials this can result in colour changes.

Operation

Permissible fuels

The following fuels are approved:

• Natural shopped wood in the form of billet wood
  Maximum length: …………………33 cm
  Circumference:………. approx. 30 cm

• Wood briquettes to DIN EN 14691
  Maximum length: …………………20 cm

OperatingOpBillet wood reaches a moisture content of 10 to 15% after being stored outdoors for 2 to 3 years (only covered at the top) and is then ideally suited for heating.

Freshly cut wood has a very high moisture content and so burns badly. Apart from the very low calorific value it is also harmful for the environment. The increased condensate and tar formation can lead to fireplace and chimney sooting.

This diagram shows that the consumption rate with freshly-felled wood (calorific value 2.3 kWh/kg) is almost twice as high as the consumption rate with dry wood (calorific value 4.3 kWh/kg)

You will only achieve optimum combustion and heat in an environmentally friendly way with these fuels. Adding the fuel in small quantities avoids unnecessary emissions. Clean burning can be identified by the fact that the firebrick becomes a light colour.

According to the German Federal Immission Control Act, it is forbidden e.g. to burn the following fuels in stoves:

• Moist wood or wood treated with wood preservatives
• Sawdust, chippings, grinding dust
• Bark and chipboard waste
• Slack coal
• Other wastes
• Paper and cardboard (except for igniting)
• Straw

Please note before heating for the first time

• Remove all accessories from the ash pan and combustion chamber.
• The odour given off by the evaporation of the protective coating disappears after the stove has been burning for several hours (ventilate the room well).
• The stove has a high quality temperature resistant coat, which does not achieve its final strength until the stove has been heated for the first time. You should therefore never leave anything on the stove and not touch the surfaces as the paint coat could otherwise be damaged.
• As soon as the kindling material has burned down, put on 2 burnouts consisting of 3 kg wood ensuring that the temperature resistant coating reaches its final firmness.

Igniting

• Before ignition, check that no flammable objects are placed on the stove.

• Empty the ash pan if necessary and slide back in.

• Open the combustion air slide valve complete.

• Grate in open position = operating lever pulled out

• Stack small amounts of firewood and, on top of it, kindling material (igniter cubes and dry, smaller kindling) and set the material alight.
  

• Close the door to the combustion chamber so that the kindling material can catch fire.

• Once there is a basic firebed, add more fuel according to the heat requirement (see chapter “Heating”).

Caution:

When heating up the fireplace, difficulties in igniting the firewood can occur if a flue draught has not yet formed in the chimney, and ventilation devices/systems are operated at the same time. In this case briefly opening a window in the installation room or temporarily switching off the ventilation system can help.

Combustion air slide valve

• Operating lever on “0”: all slide valves closed

• Operating lever on “I”:
  Secondary air slide valve completely open / Primary air slide valve completely closed

• Operating lever on “II”:
  Secondary air slide valve completely open / Primary air slide valve completely open

Regulation of combustion air

Position of operating lever:
“II”: Ignition position, max. heat output
“I”: Nominal heat output with billet wood
“1”: Nominal heat output with wood briquettes
“0”: Obtain glow

• As the secondary air also contributes to the cleanliness of the glass pane, the operating lever should be set on “I” minimum. This also applies in the event of low-load operation.
• When not operating the lever should be set on “0”, to reduce the cooling down of the room.

Fire grate

• With the help of the operating lever the fire grate can be opened or closed to move the ash from the combustion chamber to the ash pan by pushing the fire grate back and forth.
• Primary air can only enter the combustion chamber if the fire grate is set on open position.
  

Heating

• Only place the quantity of fuel required to achieve the heating requirement.
  For a nominal heating output 5,0 kW:

  • max. 1,5 kg billet wood; burning time >45 min

  • max. 1,3 kg Wood briquettes; burning time >45 min
    For max. heat output allowed:

  • max. 3 kg billet wood

  • max. 3 kg wood briquettes

• Open the combustion chamber door slowly for adding new fuel, as otherwise the combustion gases can escape.
  Attention:
  When adding more fuel, make sure that you never put more than 1.5 kg of fuel into the stove. The maximum filling height of the fuel in the combustion chamber is 20 cm. If you insert more, there is a risk of overheating.

• Empty the ash pan or combustion chamber in good time. Otherwise it is possible for the combustion air intake to be blocked or for the grate to be damaged.

• Only remove the ash pan to empty it.

• Clean the ash pan compartment regularly after removing the ash pan to remove any ash that may have been spilled (e.g. use a vacuum cleaner).

Attention:
Any stove and ash residues must have been left to cool before being removed.

Heating during the transition period

Prerequisite for the stove to function well is the correct delivery pressure (chimney draught). This very much depends on the external temperature. Therefore, if the external temperatures are high (above 16°C) the delivery pressure can be disrupted.

What to do?

• Open the combustion air slide valve complete.
• Only put on a small quantity of fuel.
• Frequently stoke the ash.

Cladding

• The cladding may not be overheated, as cracks could appear.
• Use a maximum of 3 kg wood or briquette for heating.
• As the natural cladding comes from a „grown“ boulder, structure and colour scheme may be very different.
• The surface may be altered under temperature influence.

Special information

The manufacturer’s guarantee expires if the stove is significantly or permanently overloaded above the nominal heating output, or if fuels other than those listed are used.

• The stove must only be used with the combustion chamber door shut.
• Never remove hot ashes. Only store ashes in a fireproof, non-combustible container.
• Attention: The surfaces get hot! Always use the enclosed glove when operating the stove.
• Convection air openings may not be covered.
• Never use white spirit, benzene or other inflammable, hazardous materials to ignite the fire.
• The combustion air supply fittings must never be altered. In particular, it must be ensured that any necessary combustion air pies are open while the fireplace is being used.
• Do not make any changes or modifications to the stove.
• We urgently point out that the following local and building regulations must be observed.

Cleaning

glasses
painted surfaces| as required| when cold with a slightly damp microfibre cloth

Measure the negative pressure in the combustion chamber.

Above the combustion chamber opening there is a measuring socket on which the negative pressure in the combustion chamber can be measured with a suitable measuring device during heating operation with the door closed.
