Worcester Bosch Flue Gas Collector 8716119319

The Worcester Bosch 8716119319 flue gas collector is a flue assembly component used on Worcester Bosch Greenstar CDi Classic ErP appliances. It sits in the flue gas path at the outlet of the heat exchanger, gathering the products of combustion as they leave the appliance and directing them into the flue. Correct sealing and flow through this collector support stable combustion and consistent appliance performance.
