Ideal Venturi Imax Xtra F280-F560 174384

The Ideal 174384 is a venturi for Ideal Commercial Imax Xtra appliances. It sits in the gas and air train ahead of the burner, where its tapered throat creates the pressure drop that draws in and mixes combustion air with the gas supply. Correct mixture at this point governs flame stability, combustion quality and the readings an engineer sees at the flue.

• Unstable or lifting flame at the burner, or a flame that will not hold steady across the range
• Combustion readings drifting outside the expected figures on a flue gas analyser
• Sooting or discolouration around the burner and heat exchanger
• Repeated lockouts or ignition faults traced to the gas and air mixture
• Visible damage, distortion or blockage at the venturi throat or its connections

• Confirm the appliance model and serial number against the compatibility list, as the venturi is matched to the Imax Xtra range
• Check the part number on the existing component and cross-reference it with 1780732 before ordering
• Inspect the surrounding seals and gaskets while the gas and air train is open, and replace any that are perished or compressed
• Work on the gas-carrying sections of the appliance must be carried out by a competent, registered engineer
