1 2 3 4 30 5 6 Stûv 22 - combustion Combustion air. The air needed for combusion is drawn from the outside of the building structure (under the fire or at the rear of the appliance). Combustion. The air intake, the combustion chamber and the extraction of smoke for an air-tight system, which does not hinder the insulation and ventilation of the building. Air chases combustion smoke from the window. This means you can continuously make the most of the view of the flames. The smoke is diverted through a heat exchanger then extracted through the flue. 1 2 3 4 Window lowered In open fire mode, the air taken from outside the building is brought to the fire opening inlet (overfeed by bypass). Therefore an open fire does not con- sume the warm air in the room and does not through internal ventilation off-balance. In open fire mode, the valve opens and allows the smoke to pass through without zig-zagging towards the flue. The draw needed is reduced, as well as the risk of smoke being driven back into the room. 5 6 Open fire
