What it is

The Sime 6278312 is a premix burner for Sime Format DGT HE and Open DGT HE gas boilers. It mixes gas and air ahead of the burner surface so combustion is stable across the appliance's modulation range. It is listed as a gas boiler spare in the burner category.

Signs this part needs replacing

  • Repeated ignition lockouts or failure to light
  • Unstable or lifting flame, or flame drop-out during modulation
  • Sooting, discolouration or heat damage on the burner surface
  • Poor combustion readings, including rising CO or CO/CO2 ratio
  • Combustion noise such as popping or rumbling at the burner

Before you order

  • Match your appliance model against the fit list above.
  • Check the GC number on the appliance data badge where one is listed.
  • Confirm the burner variant fitted to your boiler before ordering.
  • Gas appliance work must be carried out by a competent, registered engineer.
