Ideal Venturi Imax Xtra 80-120 174381

The Ideal 174381 is a venturi used on Ideal Commercial gas appliances. It sits in the gas and air path ahead of the burner, where its tapered bore accelerates the gas stream and draws combustion air in with it to form the correct mixture.

Because the mixture strength is set by the venturi's internal profile, the part has a direct effect on flame quality, ignition reliability and combustion readings. It is listed by Ideal under part type Venturi and is common to the Imax Xtra 80-120 family as well as several other Ideal Commercial models.

• Combustion readings drift outside the expected range and cannot be corrected at the gas valve
• Unstable or lifting flame at the burner, or a flame that will not hold steady after ignition
• Repeated ignition failure or lockout on start-up
• Soot deposits or discolouration around the burner inlet
• Visible damage, cracking or blockage in the venturi throat or its sealing faces

• Confirm the appliance model and GC number against the compatibility list, as the same part number is shared across several Ideal Commercial ranges
• Check the venturi currently fitted against part number 174381 and alternative number 1780740 before ordering
• Inspect the gasket or seal at the venturi joint and replace it if it is compressed or damaged, so the joint seals correctly on reassembly
