Broag Venturi Assembly 10 Sections S103079

The Broag Venturi Assembly 10 Sections is a gas/air venturi component used on Broag Commercial GAS 320 ACE and GAS 620 ACE condensing boilers. It forms part of the combustion air and gas mixing arrangement, where the venturi creates the pressure differential that drives premix gas and air into the burner. It is supplied as a Broag Commercial spare part under SKU S103079.

• Combustion readings that cannot be brought into specification after servicing, such as unstable or drifting CO2/O2 values.
• Visible damage, cracking or deformation of the venturi body or its connections.
• Soot deposits, debris or contamination within the venturi passage restricting gas and air flow.
• Boiler lockouts or ignition faults traced to incorrect gas/air mixture at the burner.
• Audible whistling or unusual noise from the air/gas inlet path under demand.

• Confirm the boiler model and output against the fit list, as the venturi is matched to specific GAS 320 ACE and GAS 620 ACE variants.
• Check the existing venturi assembly for physical condition and any part markings before ordering.
• Confirm the number of sections required matches the 10-section assembly specified here.
• Allow for the combustion analysis and gas safety checks required after fitting a combustion-related component.
