The heat is returned to the room through an opening located between the combustion chamber and the Stûv 16 casing. No fan is required since convection is by natural gravity for these models of wood fireplaces and inserts.

Connection to the outside air intake

An opening under the device is specially designed to connect an outside air intake directly to the Stûv 16 combustion chamber. The fire then takes oxygen outside the house and thus ensures optimal combustion.

A mobile smoke deflector opens and closes with the door on the Stûv 16. When the door is open, it allows the smoke to escape, thus avoiding backflow into the room, and when the door is closed, the deflector prevents the smoke from being quickly exhausted, thus ensuring a second combustion of the gases in the device.

A small spring is positioned at the bottom of the Stûv 16 door to ensure its closure when released. When the door of these models of wood fireplaces and inserts is partially closed, it creates a blowing effect on the flames that is very useful for lighting the fire and prevents sparks or embers from falling to the ground.

The hinged door of the Stûv 16 has two hooks to ensure its solidity and make the combustion chamber of these models of wood fireplaces and inserts even more airtight.
