What it is
This is a heat exchanger cleanout gasket supplied with its plate, manufactured by Johnson & Starley. It seals the cleanout aperture on the heat exchanger of Johnson & Starley warm air units and boilers, allowing the cleanout cover to be refitted with a sound gas-tight joint after servicing.
Signs this part needs replacing
- Visible cracking, hardening or flattening of the gasket material
- Signs of leakage or staining around the heat exchanger cleanout cover
- Gasket breaks up or sticks to the mating face when the cleanout plate is removed
- Combustion readings or flue gas analysis indicating a poor seal at the cleanout
- Gasket reused after a cleanout and no longer seating correctly
Before you order
- Confirm the appliance model and variant against the fitment list
- Check whether the unit is a standard, MAF, MAF VI or Mk3 build
- Inspect the cleanout plate and mating face for damage before refitting
- Verify the existing gasket and plate arrangement matches this assembly
