Ideal Injector Kit Dia 3.35 System 18 176892

The Ideal 176892 is an injector kit with a 3.35 mm diameter, produced for System 18 appliances in the Ideal Vogue family. The injector controls the flow of gas into the burner, so its bore size directly affects the gas rate and combustion performance of the appliance. It is a serviceable component and is replaced as a complete kit rather than as a loose jet.

• The boiler fires but the flame is weak, uneven or unstable across the burner.
• Combustion readings drift outside the expected range and cannot be corrected by adjustment.
• Sooting, discolouration or deposits around the burner or heat exchanger.
• Repeated ignition failures or lockouts shortly after the burner lights.
• The injector is visibly blocked, corroded or damaged when inspected during a service.

• Confirm the appliance model and GC number against the compatibility list, as several Vogue S18 variants use different injector sizes.
• Check the existing injector marking to confirm the 3.35 mm bore is the correct one for the appliance.
• Note the alternative part number 1782581 when cross-referencing older documentation or stock records.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
