What it is

The rear sealing cap kit is a flue assembly component for Ideal gas boilers. It seals the rear of the flue manifold, closing off the joint where the manifold meets the appliance casing so that products of combustion stay within the flue path. It is used across the Ideal Logic and Logic+ Heat range and is supplied under part number 176053.

Signs this part needs replacing

  • Flue gas readings drifting outside the expected range on a combustion analysis
  • Visible cracking, hardening or distortion of the existing seal
  • Staining or condensate tracking around the rear of the flue manifold
  • A smell of combustion products near the appliance casing
  • The cap or seal disturbed or damaged during servicing of the flue manifold
