What it is

The Baxi combustion test point plug, part number 720127401, is a service component used on the Bermuda BBU 15 HE appliance. It seals the combustion test point on the appliance, allowing flue gas readings to be taken during commissioning and servicing and closing the port off once testing is complete.

Signs this part needs replacing

  • Flue gas or combustion readings escaping from the test point during analysis
  • Visible damage, cracking or corrosion on the plug body
  • Perished, flattened or missing sealing washer
  • Plug seized in the test point or hex/head rounded off
  • Soot staining or condensate tracking around the test point

Before you order

  • Confirm your appliance is a Baxi Bermuda BBU 15 HE
  • Check the existing plug and its seal for damage before ordering
  • Verify the part number 720127401 against the manufacturer's parts list for your model
  • Confirm the test point is accessible and the appliance is isolated before work begins
