Combustion air supply
Combustion air supply – Regel-air® for the support of room-sealed heating appliances
With room-sealed heating appliances, the air required for combustion must flow from outdoors into the rooms where the heating appliances are installed. The Regel-air® window rebate vents FFL are used as approved air intake elements. They ensure the required air intake and guarantee perfect combustion and flue gas evacuation. A dangerous negative pressure cannot occur because outdoor air is flowing in.
Living comfort is not affected by the use of the approved window vents.
The number of Regel-air® window rebate vents, which are not visible, can be calculated correctly for combustion air supply.
