Ideal Injector Kit 4.0 Dia 179297

The Ideal Injector Kit 4.0 Dia is a factory injector assembly supplied for Ideal Commercial appliances. The injector sits in the flow path and presents a fixed 4.0 diameter orifice, so the rate of flow through that point is set by the size of the jet rather than by an adjustable screw or regulator. It is listed under Ideal part number 179297 and is also referenced by the alternative number 8904205.

Because the orifice diameter is fixed, the injector is matched to a specific appliance and application. A worn, blocked or incorrect injector changes the flow rate at that point, which is why the diameter marked on the kit should be checked against the appliance data before fitting.

• Flow at the appliance is weak, uneven or noticeably different from the commissioned setting.
• The injector orifice is blocked, partially blocked or visibly contaminated with debris or scale.
• The jet shows mechanical damage, distortion or wear around the orifice.
• Output or combustion readings drift and cannot be brought back to specification by normal setting up.
• The injector has been removed for cleaning and the orifice diameter no longer matches the appliance data plate.

• Confirm the appliance model and, where a GC number is shown on the data plate, quote it when checking compatibility.
• Check the diameter marked on the existing injector against the 4.0 figure for this kit before ordering.
• Note the alternative number 8904205 so the correct item can be identified if the original number has been re-labelled.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
