Left corner fireplace insert ALBERO AL11L.HD
Left corner fireplace insert ALBERO AL11L.HD This steel model has a nominal power of 11 kW and features a glass front and a side window on the left side. The corner design provides a wide view of the fire, allowing the flames to be visible from two directions.
The heating load range from 5.5 to 14 kW allows the insert's operating intensity to be adjusted to the current heating demand. At the same time, this model allows for the creation of a warm enclosure, so it can also be used in installations designed to gradually release energy into the room.
AL11L.HD is one of the popular ALBERO fireplace insert seriesThe line combines solutions that support efficient combustion with the ability to personalize the handle, covers, and fireplace insert.
Front glazing and left side window
The most important distinguishing feature of the model is corner glazing with side glass on the left sideThis arrangement allows you to observe the fire both from the front and from the left side of the room.
As a result, the insert works well in built-ins placed against a wall, on the border of two functional zones, or in a location visible from several parts of the living room. This allows the fireplace to serve as a distinctive element of the open-plan living area.
The glazing dimensions given for the AL11L.HD model are: 590 × 430 × 375 mmHowever, before installing the unit, please use a current technical drawing to ensure all installation dimensions of the unit are correctly taken into account.
Left-sided fireplace insert for various arrangements
The left side glass should be adjusted to the fireplace's location and the direction from which the fire will be most frequently viewed. Therefore, the AL11L.HD model may be a suitable solution, for example, when the lounge area is located on the left side of the building.
Moreover, the corner design allows the fireplace to visually open up to a larger portion of the room. This means the fireplace doesn't restrict the view of the fire to a single axis, as is the case with inserts with straight front glass.
Heat-resistant ceramic glass
The doors are equipped with heat-resistant ceramic glass suitable for operation at temperatures up to 800°CThe material allows for safe observation of flames and retains its properties during proper use of the insert.
At the same time, the steel door, made with a special profile, provides adequate rigidity and resistance to high temperatures. This design supports proper door adhesion and sealing during regular use of the fireplace.
A system that helps keep the glass clean
The ALBERO AL11L.HD fireplace insert is equipped with an air curtain supporting the clean glass effectThe airflow directed along the inner surface of the glazing helps reduce the build-up of soot and other contaminants.
This allows the front and side windows to remain clear for longer periods of time. However, the system does not eliminate the need for periodic cleaning of the glass.
The effectiveness of an air curtain is influenced by factors such as wood moisture content, chimney parameters, lighting method, and air supply settings. Therefore, the device should be used in accordance with the manufacturer's instructions.
Nominal power 11 kW
The nominal power of the ALBERO AL11L.HD insert is 11 kWThe heating load ranges from 5.5 to 14 kW, allowing you to adjust the device's operating intensity depending on the current heat demand.
The model can be used as an additional heating source in the living room, open-plan living area or other room intended for the installation of a wood-burning device.
The power selection should take into account, among other things, the cubic capacity of the room, the building's insulation standard, the interior layout, and the parameters of the chimney flue. Therefore, it's worth consulting a qualified installer when selecting an insert.
Thermal efficiency at the level of 83%
The thermal efficiency of the AL11L.HD model is 83%A properly designed air supply system supports stable combustion and efficient use of the energy contained in the wood.
The special design of the rear body allows for the introduction of secondary air into the upper combustion zone. This air helps to burn the gases produced during fuel combustion.
As a result, the combustion process can be carried out more precisely, which helps to reduce the products of incomplete combustion and maintain the declared efficiency of the device.
Emission parameters AL11L.HD
Pollen emissions at 13% O2 totals 38 mg/m³. In turn, CO emissions at 13% O2 totals 1243 mg/m³.
Obtaining the declared parameters requires the use of properly seasoned wood, ensuring proper chimney draft and correct connection of the device.
Furthermore, the fuel quantity, ignition method, and airflow adjustment must meet the requirements specified in the manual. This ensures the insert can operate within its intended power range.
External air intake
The steel base of the insert is equipped with external air intake damperThis allows the air needed for combustion to be supplied directly from outside the building.
This solution reduces the need to draw air exclusively from the heated room. This is particularly important in modern buildings characterized by high airtightness.
The diameter of the intake port is 125 mmThe duct should be designed to allow the free flow of an appropriate amount of air to the furnace.
A fireplace insert for a house with heat recovery
The AL11L.HD model is adapted for use in buildings equipped with heat recoveryThe external air intake helps reduce the impact of the fireplace on the air balance in the room.
At the same time, the fireplace installation and mechanical ventilation should be properly designed and adjusted. This will ensure proper operating conditions for both systems.
It's important to plan the air supply before beginning construction. This helps avoid conflicts with other installations and maintain required installation distances.
Exhaust gas discharge through a 200 mm flue
The diameter of the flue pipe of the AL11L.HD fireplace insert is 200 mmThe chimney and exhaust connection must be adapted to the parameters of the appliance.
Before installation, it is necessary to verify, among other things, the height and cross-section of the chimney, the available draft, the method of connection and the possibility of periodic cleaning of the installation.
The final assessment of the connection conditions should be carried out by a qualified installer or a person with appropriate chimney qualifications.
Possibility of creating a warm building
The ALBERO AL11L.HD insert allows you to make warm fireplace installationThis allows the use of carefully selected storage materials that absorb some of the heat energy and then gradually transfer it into the room.
This allows for heat release to be more evenly distributed over time than with a standard lightweight convection enclosure. However, the materials used and the enclosure design must meet the requirements of the specific installation.
The ability to create a warm enclosure does not mean freedom in restricting airflow. The entire system must be designed in accordance with the device documentation and thermal protection principles.
Required active fields of the grids
The active area of the outlet grilles should be from 770 to 880 cm². In turn, the required active area of the inlet grilles is in the range of 440 to 720 cm².
Intake vents allow cooler air to be drawn into the space around the body. The heated air can then be discharged into the room through exhaust grilles.
Thanks to a properly designed flow, heat is effectively transferred to the interior and the built-in elements are protected against excessive temperature increases.
P265GH boiler steel body
The insert casing is made of P265GH boiler steel grade compliant with EN 10028-2This material is intended for applications requiring operation at elevated temperatures.
