Worcester Bosch Blast Tube PL10/14 87161565810

The blast tube is the Worcester Bosch component that sits at the burner end of the combustion assembly, directing the air and fuel mixture into the combustion chamber and shaping the flame pattern. It is listed for the PL10/14 appliance range and carries the Worcester Bosch part number 87161565810. As a combustion-path component, it is exposed to high temperatures and repeated ignition cycles throughout its service life.

• The burner flame becomes unstable, lifts off the burner head or fails to hold a steady pattern.
• Combustion readings drift outside the expected range and cannot be corrected by normal servicing adjustments.
• Soot deposits or discolouration appear around the burner and combustion chamber.
• The appliance locks out on ignition, or ignition becomes rough and inconsistent.
• Visible distortion, cracking, corrosion or heat damage is found on the tube during a service inspection.

• Note the model and GC number from the appliance data badge and confirm it matches the compatibility information for this part.
• Check the existing blast tube against the part number and alternate numbers listed here before removing it.
• Inspect the burner gasket and any seals at the same time, as these are commonly disturbed when the blast tube is removed.
