Within this Baxi Burners category we list either Main Burner and burner components and pilot injectors as well as Pilot burner assemblies. Baxi Main burners are the component within the boilers that create and manage the flame which in turn heats the water. Baxi Pilot burners are a spare or device which light the main burners and can be either permanent or electonic, switched on upon demand. Pilot Injectors are a small but important part within the pilot assembly which helps regulate the supply of gas or LPG. All our Baxi Burners spares are new and genuine manufacturer spares.
