Ideal Venturi Deflector 176901

The Ideal 176901 is a venturi deflector, a small internal component that sits in the air and gas path of the appliance. It shapes and directs the incoming flow so the mixture reaching the burner stays consistent, which is what keeps combustion stable across the firing range.

It is supplied under the Ideal Spares banner and is used across the Vogue range, including the commercial variants of those appliances. The part is also listed under the alternative number 1782537.

• Unstable or weak flame at the burner, with the appliance struggling to hold a steady firing pattern
• Repeated ignition lockouts or flame supervision faults after the boiler has fired
• Soot deposits, discolouration or heat marking around the burner and combustion chamber
• Flue gas readings that drift outside the expected range on a combustion analyser
• Whistling, popping or unusual intake noise from the air and gas path

• Check the GC number on the appliance data badge against the compatibility list, as several Vogue variants use different numbers
• Confirm the alternative number 1782537 if you are working from an older parts reference
• Inspect the surrounding seals and gaskets while the assembly is apart and replace any that are perished or flattened
