What it is

The Ariston 60000633 is a gas restrictor with a stated diameter of 4.50 mm, used in the gas train of selected Ariston gas boilers. It meters the gas flow through the appliance so the burner receives the correct input rate for its setting. It is listed by the manufacturer under gas boiler spares.

Signs this part needs replacing

  • Gas rate or burner pressure readings that cannot be set to the values in the appliance instructions
  • Combustion readings at the flue outside the expected range for the appliance
  • Unstable or weak flame at the burner, or repeated failure to establish a flame
  • Whistling or hissing from the gas train that persists after the inlet pressure has been checked
  • Restrictor found blocked, damaged or missing during a service or gas train inspection

Before you order

  • Confirm the appliance model and GC number from the data badge against the fit list above
  • Check the diameter marked on the restrictor currently fitted, as more than one size is used across the range
  • Confirm the appliance is a natural gas (NG) model, as the fit list covers NG variants only
  • Check the manufacturer's parts list for your exact model variant before ordering
