Ideal Restrictor Plate 545kW 178148

The Ideal 178148 is a restrictor plate rated for 545kW, supplied as part of the casing assembly for Ideal Commercial appliances. It is a manufacturer-supplied component that forms part of the casing arrangement on the Imax Xtra EL range. Because the plate is matched to the 545kW output of the appliance it serves, the rating must be confirmed against the boiler before ordering.

• Combustion readings drifting outside the values expected for the appliance after servicing
• Flue or heat exchanger temperatures running higher than normal for the same load
• Visible distortion, corrosion or heavy soot build-up on the plate
• Noise or vibration from the flue path that was not present previously
• Repeated lockouts or shutdowns that persist after the usual service checks

• Confirm the appliance is the 545kW Imax Xtra EL variant, as the plate is rated to that output
• Check the part number against the appliance data plate and any service documentation
• Inspect the casing seals and gaskets while the casing is open and replace any that are damaged
