1.4. Operating principle
The insert is made to fit into an existing chimney. It can
also be used as the hearth of a chimney about to be built
and is designed to receive the fire.
Heat is mainly diffused by radiation through the window
and by hot air diffusion around the body of the
appliance.
The air, collected at the bottom of the appliance,
spreads around the body, where it becomes hot with the
appliance wall radiation.
The hot air rising up goes to the room through the grille
located in the hood or to the adjacent rooms via ducts
connected to jets above the appliance's heat
exchanger.
Model 634 10 49 only : The air leaving the heat
exchanger is accelereted by the automatic start of the
fans when the hot air temperature is more than 50 °C.
The fans stop when the air temperature fall down.
This appliance is designed to be used only with the
door closed .
The speed is regulated with the primary air flap situated
on the main door.
A clever secondary air inlet entry through the top of the
glass door and the hearth plate completes the
combustion of volatile components and allows the door
to remain clean.
The draught restrictor enables you to balance the
combustion rate.
