What it is

The Sime 5185121 is a conversion kit to LPG for Sime gas boilers in the Dewy and Planet Dewy ranges. It allows a compatible appliance to be converted from natural gas to liquefied petroleum gas. The kit is listed by Sime for use across the Dewy 30/80, Dewy 30/130 and Planet Dewy models.

Signs this part needs replacing

  • The boiler is being installed or operated on an LPG supply rather than natural gas.
  • The existing conversion components are missing, damaged or incomplete.
  • The appliance is not running correctly on LPG, with unstable or incorrect burner performance.
  • A previous conversion has been removed or reversed and the boiler is being returned to LPG operation.

Before you order

  • Confirm the boiler model and, where shown, the GC number against the fitment list.
  • Check the appliance's current gas type and whether conversion to LPG is required.
  • Verify that part number 5185121 matches the number on the existing component or the manufacturer's parts list.
