What it is

The Alpha 3.021583 is a heat exchanger seal kit for Alpha gas-fired appliances. It provides the sealing components required at the heat exchanger assembly, where a sound water- and gas-tight joint is essential to safe and correct operation. The kit is listed for the Alpha CD90S and CD115S LPG models.

Signs this part needs replacing

  • Seals that have hardened, flattened or cracked with age
  • Repeated pressure loss or air ingress traced to the heat exchanger
  • Seals disturbed or damaged during heat exchanger removal or servicing

Before you order
