The Baxi 5114009 is a genuine OEM complete burner kit designed for use in Baxi Solo HE boilers. This kit includes the full burner assembly required to maintain clean, efficient combustion and stable boiler performance.

The burner is responsible for mixing gas and air at the correct ratio and delivering a consistent, controlled flame to the heat exchanger. Over time, burners can become worn, blocked, or corroded, leading to poor combustion, ignition issues, noisy operation, high CO/CO₂ readings, or boiler lockouts. Replacing it with this genuine Baxi burner kit restores safe, efficient operation.
