For replacement of Heat Exchanger Seals on Flexicom, Ultracom & Betacom2 Boilers

• This door seal is a spare part for the heat exchanger of CXI, HXI, Ultimate, Ultracom, Ultracom2, Betacom, Easicom, Eden, Energy, Xtramax, SXI, Ultrapower and British Gas appliances.
• The heat exchanger transfers heat from a boiler’s burner to water.
• All boilers have a primary heat exchanger

The burner heats up to raise the temperature of the water in the system

Only combis have a secondary heat exchanger this allows the heat to be transferred between closed systems.

Seals are designed to prevent leaks of water or harmful gases as they move through the boiler.
