Ideal Connecting Venturi Imax Xtra 174448

The connecting venturi is a gas and air metering component used on Ideal Commercial Imax Xtra boilers. It sits in the air/gas pathway and shapes the flow so the mixture reaching the burner stays within the range the appliance was set up for. This is the Ideal part numbered 174448, listed by the manufacturer as a connecting venturi for the Imax Xtra range.

• Combustion readings drift outside the values expected for the appliance, with no other obvious cause
• Unstable or noisy flame at the burner, or a flame that will not hold steady
• Repeated ignition faults or lockouts after the appliance has been serviced
• Soot deposits or discolouration around the burner area
• Visible damage, cracking, blockage or debris build-up on the venturi itself

• Confirm the appliance model and serial number against the compatibility list, as the Imax Xtra range covers several output sizes
• Check the part number on the component being removed against 174448 before ordering
• Inspect the surrounding seals and gaskets while the venturi is out, and replace any that are compressed or perished
• Work on the gas and air pathway should be carried out by a competent engineer, with combustion readings checked after reassembly
