Up To 20 Meter Extended Flueing (Ø60 / Ø100 Concentric Vent)
Extended venting of up to 20 metres is possible due to the built-in APS (Air Pressure Sensor). This unit senses air pressure and as such will provide the accurate amount of air required for the burner combustion. This ensures that a consistent heat output is maintained in any weather condition including strong winds. Many other UK boilers are only capable of using flueing systems that extend to 15 metres high. READ MORE ABOUT FLUES AND FITTINGS.
