Stoves and fireplaces are beautiful decorative objects which can provide great enjoyment, but they must also be functional to create comfort and to meet different requirements. JC BORDELET has therefore developed a heat and combustion regulation system that is both effective and easy to use. The air inlet is adjusted by adjusting the inlet handle located on the door of the ash drawer or on the lower part of the front. The nozzle valve and air inlet valve are used to regulate the combustion rate.
