Baxi Burner Assembly 30/39kW 720541601

The Baxi 720541601 is a burner assembly rated for 30/39kW operation, manufactured by Baxi for the Avanta range of gas combi boilers. It sits at the heart of the combustion process, presenting the gas and air mixture at the burner head so that it ignites evenly across the surface and produces a stable flame into the heat exchanger. The assembly is common to both Baxi and Broag Remeha badged versions of the same 39C combi platform.

• Elevated carbon monoxide readings during flue gas analysis
