Worcester Bosch Baffle Retainer Key 87161119580

The Worcester Bosch baffle retainer key (part number 87161119580) is a small locating component used inside the heat exchanger of Worcester Bosch oil-fired boilers. It holds the baffles in their correct position within the flue ways, keeping the flue gas path as the designer intended. Correct baffle alignment matters for heat transfer and combustion performance, so the retainer is a functional part rather than a cosmetic one.

• Baffles sitting loose, dropped or misaligned in the flue ways
• Rattling or metallic noise from the heat exchanger area during firing
• Soot or heavy deposits building up around the baffle positions
• Reduced heat transfer, with the boiler struggling to reach or hold temperature
• Retainer found distorted, corroded or broken during a service strip-down

• Confirm the boiler model and serial number against the compatibility list, as the Camray range covers several output variants
• Check the existing part against alternative number 1021678 before ordering
• Inspect the baffles themselves at the same time, as a damaged retainer often accompanies damaged or displaced baffles
• Work on the combustion side of an oil appliance should be carried out by a competent engineer and the boiler re-commissioned afterwards
