Primary air deflected through grate 13 is complemented by secondary, flushing air promoting cleaning of heat-proof glass and flow of smoke gases and burning of materials, and tertiary air deflected in equipartition through the back and side walls of the firebox, which lights still combustible gases, ensuring more efficient combustion.
  • the solution according to the invention offers the advantage of corresponding with the new DIN Standard, demanding higher requirements from combustion products. It conforms with higher level standard prescriptions with its higher efficiency and with more favorable flue gas emission. Deflection of smoke gases through the back prevents occurring of usual coming out of smoke when opening the firebox door.
  • the fireplace insert according to the invention can be built in cockle stove or fireplace built in wall as well. Conditions of proper operation should be created according to the code of building fireplaces.
