What it is
The lower baffle is a Worcester Bosch component listed under part number 8737602342. It is fitted within the heat exchanger assembly of Greenstar 2000 Combi appliances, where it directs the flow of combustion gases across the heat exchanger surfaces. Correct fitting of the baffle is essential to maintain efficient heat transfer and stable combustion.
Signs this part needs replacing
- Overheat faults or repeated overheat lockouts during demand
- Combustion readings drifting outside the expected range on a flue gas analysis
- Sooty deposits, discolouration or localised hot spots around the heat exchanger
- Rattle or unusual combustion noise from the heat exchanger area
- Visible distortion, cracking or corrosion of the baffle on inspection
Before you order
- Confirm the boiler model and GC number against the fitment list before ordering
- Check the existing baffle position and orientation so it can be refitted correctly
- Inspect the heat exchanger and seals while the appliance is open, as other components may also need attention
- Verify the part number 8737602342 matches the component being removed
