What it is

The Ideal 078881 is a sightglass assembly, marked Sup 3, used on Ideal Commercial Concord Super Series appliances. It forms the viewing window into the combustion chamber, allowing the flame and burner condition to be checked during servicing and commissioning. It is supplied by Ideal Spares as a complete assembly.

Signs this part needs replacing

  • Cracked, chipped or crazed sight glass
  • Glass discoloured or coated with soot, obscuring the flame view
  • Condensation or moisture trapped behind the glass
  • Staining or leakage around the sightglass mounting
  • Damaged or perished sealing face on the assembly

Before you order

  • Check the appliance GC number against 41-415-68 or 41-415-69, or confirm the model in the compatibility list.
  • Confirm the existing assembly is marked Sup 3, as earlier sightglass assemblies differ.
  • Check whether the mounting gasket or seal needs renewing at the same time.

Not sure which part?

Tell the parts assistant what it's going into — the appliance make and model, or the GC number off the data badge — and it will check this part is on the fit list.
