Modern KDZ fireplace cassette insert is compact heating equipment. It can be fitted into existing open fireplaces. 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 cassette insert transfers heat by radiating energy through the front glass by means of installed fans.
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.
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.
USE CONVENIENCY
It is easier to keep the insert clean thanks to the grate and an ash pan, where ash collects.
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.
