What it is

The Andrews 7781603 is a 200 mm flue seal for Andrews water heaters. It seals the flue connection at the appliance, preventing flue gases and condensate from escaping at the joint. It is a service part intended for maintenance and repair of Andrews hot water equipment.

Signs this part needs replacing

  • Visible cracking, hardening or perishing of the seal material
  • Condensate or water tracking around the flue joint
  • Flue gases or combustion odours detected near the appliance connection
  • The seal no longer sits tightly or has become displaced from its seating
  • Soot staining or discolouration around the flue collar

Before you order

  • Confirm the flue connection on your appliance takes a 200 mm seal
  • Check the appliance model against the manufacturer's parts list to confirm 7781603 is the correct item
  • Inspect the flue collar and sealing face for damage before fitting a new seal
  • Isolate the appliance and allow it to cool before removing the existing seal
