DAFS (Double Air Flow) technology allows additional oxygen to be supplied through the air jets strategically positioned at the back of the combustion chamber. Making the unit more efficient, reducing emissions, cleaner glass and better heat output (Excludes Seguin Multivision series).
1. Normal combustion with primary air (ambient air): gases and fumes are burnt.
2. Double combustion: Seguin adds a double back plate at the back of the appliance. Additional oxygen enters in this double back plate (air coming from the ambient room or directly connected to the outside air). When this air reaches 600°C in this double back plate, it is injected inside the combustion chamber thanks to the air jets (holes). Those holes are located at a certain level of the combustion chamber (middle) in order to burn again gases and fumes not burnt during the primary phase.
All Seguin fireplaces have the option to be equipped with an outside air kit which is directly connected to the outside of your home. The firebox can then operate without using air from inside the room, with both primary and secondary air combustion stages being drawn directly from the fresh air outside.
Better efficiency, recommended for 6 star rated homes or homes that are tightly sealed, no oxygen drawn from inside your home
