What it is

The Andrews 7781602 is a 130 mm flue seal used on Andrews water heaters. It seals the flue joint at the appliance, preventing flue gases and condensate from escaping into the surrounding space. It is a serviceable component, replaced during flue maintenance or repair.

Signs this part needs replacing

  • Visible cracking, hardening or perishing of the seal material
  • Soot staining or discolouration around the flue joint
  • Condensate weeping or damp marks at the flue penetration
  • Flue gas odours or draughts detected near the flue joint
  • Seal displaced or no longer seated correctly in the flue opening

Before you order

  • Confirm the flue diameter matches 130 mm
  • Check the appliance model against the manufacturer's parts list
  • Inspect the flue joint and surrounding components for damage before fitting
