What it is

The Alpha 1.020394 is a seal for the heat exchanger flue outlet pipe. It is fitted to Alpha Cd70S (LPG) appliances, where it seals the joint between the flue outlet pipe and the heat exchanger. The seal prevents flue gases and condensate from escaping at this connection.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the seal
  • Soot or condensate staining around the flue outlet joint
  • Signs of flue gas leakage at the heat exchanger connection
  • Water or condensate dripping from the joint
  • Combustion readings outside the expected range during servicing

Before you order

  • Confirm the appliance model is Alpha Cd70S (LPG)
  • Check the existing seal for damage or deterioration
  • Verify the part number 1.020394 against the manufacturer's parts list
