Combustion air supply
Regel-air® for use with room-air-dependent fireplaces
In the case of room-air-dependent fireplaces, the air required for combustion must flow in from outside into the rooms where the fireplaces are installed. The Regel-air® window rebate vents FFL serve as an approved supply air element. They provide the necessary supply air and guarantee proper combustion and flue gas extraction. The inflow of outside air prevents any dangerous negative pressure from developing.
Living comfort is not compromised by the use of the recognised vents.
The number of visually unobtrusive Regel-air® window rebate vents that are not visible to the naked eye can be correctly calculated for the combustion air supply.
