What it is
The terminal outlet is the external end of the flue assembly on a Worcester Bosch boiler. It forms the point where the products of combustion and the steam produced during normal operation leave the flue and discharge to outside air. It is supplied by Worcester Bosch under part number 87161112090 and sits within the flue and terminal component group.
Signs this part needs replacing
- Visible cracking, distortion or impact damage to the terminal body or its grille
- Corrosion, staining or discolouration around the terminal outlet
- Condensate or combustion staining on the wall or surface behind the terminal
- Boiler lockout or flue-related fault codes traced to the terminal or flue run
- Discolouration or sooting at the discharge point suggesting the flue is not clearing correctly
Before you order
- Check the boiler model and GC number on the appliance data badge, as flue components vary with appliance location and model
