What it is

The combustion tube set is a manufacturer part for Andrews water heaters, supplied under part number Z497. It forms part of the combustion chamber assembly, where the burner flame and flue gases are contained and directed. The set is listed in the manufacturer's catalogue as a combustion box kit.

Signs this part needs replacing

  • Visible corrosion, scaling or heavy soot build-up on the tube surfaces
  • Cracking, perforation or burn-through of the tube material
  • Distortion or warping of the tube, which can affect flame pattern
  • Unstable flame, flame lift or combustion readings outside the appliance's specified tolerance
  • Flue gas leakage around the combustion chamber area

Before you order

  • Confirm the appliance model and serial number against the manufacturer's parts list
  • Check that Z497 is the correct combustion tube set for your Andrews water heater
  • Inspect the surrounding seals, gaskets and fixings, as these may also need attention
  • Verify the existing combustion chamber components before removal so the assembly can be refitted correctly
