Modern KDZ K fireplace cassette insert is compact heating equipment. It can be fitted both into existing open fireplaces and in a new mantel. Thanks to the applied solutions, such as turbines (forced convection), the cassette insert enables very effective use of heat from combustion of wood, making the equipment a very economical source of heat. It allows to effectively heat a room, in which it is installed. KDZ K cassette insert transfers heat by means of radiation and thanks to fans, provides a lot of hot air.

MAXIMUM USE OF ENERGY

More effective combustion and maintaining of the temperature for a longer period of time is achieved through lining the furnace with Termotec, a material that accumulates heat and increases the temperature inside.

The cassette is equipped in turbines fitted under the furnace with the capacity of 280 m3/h and low power consumption (38W). The turbines are responsible for forced circulation of air in the device, which results in more effective heat transfer to the surroundings. The equipment features three-stage control of the fans operation. Depending on made selection:

- position 0 - the turbines start automatically and operate with reduced speed after the temperature sensor reading reaches 50°C. (The sensor is installed under the ash pan at the front of part of the cassette.),

- position 1 – the turbines operate continuously with reduced speed, depending on the operation of the cassette insert,

- position 2 – the turbines operate continuously with full speed, regardless of the operation of the cassette insert.

 

DESCRIPTION OF AIR CIRCULATION

Natural air circulation - starts upon firing up of the cassette insert,

Forced air circulation - starts when the fans are started up. The purpose of the fans is to increase the air flow along the external walls of the cassette insert, and first of all to collect and transfer the heat energy to the room. The fans are installed directly at the front of the cassette insert, underneath the furnace. Apart from the fans, the kit comprises a controller and a head with a temperature sensor, all interconnected by capillary tubes. The power is supplied to the fans with the capacity of 280 m3/h from 230 V mains. The system can be started automatically or manually. Air is drawn from the room via two holes at the front of the cassette below the door. Flowing air collects heat from the space surrounding the furnace and transfers it to the room.

 

DESCRIPTION OF THE COMBUSTION AIR CIRCULATION

Air to the furnace is drawn from the room.The amount of primary air supplied under the fire grate is controlled using a mechanism (a controller) located under the insert door.

The stove has a system of double air supply to the furnace - primary air and an air curtain.

Primary air is supplied under the fire grate located in the furnace bed. Air is supplied to the furnace from a space (air chamber) underneath the grate, on which combustion takes place.

Secondary air is supplied through holes in the upper part of the cassette insert. This way oxygen is supplied to the upper part of the furnace. Air control, the so-called air curtain, is provided by a mechanism installed over the stove door. Opening of the mechanism enables supplying air to the upper part of the insert, where reburining of the gases coming from combustion of wood takes place, the same reducing the emission of harmful CO to the atmosphere.

 

USE CONVENIENCY

It is easier to keep the insert clean thanks to the grate and an ash pan, where ash collects. Additionally, the application of the clean glass system reduces the deposition of soot. The glass is separated from the furnace by an air curtain. Air directed onto the guide “licks” the glass, moving flames and smoke away from it, which significantly reduces the deposition of soot, making the glass stay clean. 

 

MODERN DESIGN

The cassette insert is equipped in a single decorative glass, which makes it look elegant and modern. This solution makes optically the front of the insert bigger and emphasizes the view of fire. The insert door is equipped in a convenient handle.

 

ECOLOGICAL COMBUSTION

The unit meets the requirements of Ecodesign standards and the restrictions of the BImSchV 2 standard, which determines the maximum CO emission.
