What it is

The Ideal 178146 is a restrictor plate rated at 395kW, listed by the manufacturer under the casing assembly group. It sits within the flue and combustion path of the appliance, where it controls the flow of gases through the heat exchanger and helps hold the gas/air ratio within the range the boiler was set up for. It is an Ideal Commercial component intended for the Imax Xtra EL range.

Signs this part needs replacing

  • Combustion readings drift outside the values recorded at commissioning
  • Flue gas analysis shows the appliance running outside its specified CO/CO2 band
  • Visible distortion, corrosion or erosion of the plate surface
  • The plate no longer seats correctly or its fixing points are damaged
  • Repeated lockouts or unstable firing after other combustion components have been checked

Before you order

  • Confirm the appliance model and rating — this plate is specified for the 395kW version
  • Check the part number stamped or printed on the existing component against 178146
  • Have the appliance recommissioned and combustion readings re-taken after fitting
