What it is

The Ideal 178145 is a restrictor plate rated at 320kW, supplied for Ideal Commercial appliances. It sits in the flow path of the appliance and limits the passage of flue gases or air so that combustion stays within the design parameters for that output. It is a serviceable component, so it is replaced when flow is restricted beyond specification or the plate itself is damaged.

Signs this part needs replacing

  • Combustion analyser readings drifting outside the values recorded at commissioning
  • Unstable, lifting or noisy flame at the burner
  • Repeated lockouts or overheating during normal running
  • Visible distortion, corrosion, sooting or blockage found when the plate is inspected
  • Flow through the appliance noticeably reduced against previous service records

Before you order

  • Confirm the appliance model and, where shown on the data badge, the GC number against the compatibility list before ordering
  • Check the rating on the existing plate matches the output of the appliance it is being fitted to
  • Inspect any gasket or seal disturbed during removal and renew it if it is no longer serviceable
