What it is

The Ariston Venturi G20 is a gas/air mixing component used in the combustion circuit of Ariston CLAS Premium EVO appliances. It meters the incoming gas stream and draws in combustion air to form the correct mixture before the burner. This version is specified for G20 (natural gas) operation at 35-38 kW.

Signs this part needs replacing

  • Boiler locks out or fails to establish a stable flame on ignition
  • Unstable or lifting flame at the burner
  • Whistling or roaring noise from the combustion area
  • Poor combustion readings that cannot be corrected by servicing
  • Visible damage, blockage or debris in the venturi throat

Before you order

  • Confirm the appliance is set for G20 (natural gas) and rated 35-38 kW
  • Check the existing venturi part number against 6500672700
