What it is

The draught diverter housing is an Alpha component for CB28 and CB28X LPG gas boilers, supplied under part number 3.012786. It forms the housing around the draught diverter, the section that stabilises the flue draught and routes combustion products away from the appliance. The housing is a serviceable part and is replaced when the existing unit is corroded, distorted or no longer sound.

Signs this part needs replacing

  • Visible corrosion, perforation or holing of the housing
  • Soot deposits or staining around the diverter area
  • Flue gas spillage at the diverter picked up during commissioning or a service check
  • Heat distortion or physical damage to the housing body

Before you order

  • Confirm the boiler is a CB28 or CB28X LPG model before ordering
  • Check the existing housing against part number 3.012786
  • Inspect the diverter area for corrosion and sooting to confirm the fault lies with the housing
  • All gas-related work must be carried out by a Gas Safe registered engineer
