What it is
The Ideal 157904 is a gas injector with a 5.5 mm bore, supplied as a spare for Ideal Commercial boiler appliances. It is the metering component that controls the flow of gas into the burner, so the bore size directly determines the input rate and flame characteristics of the appliance. This injector is listed against the Ideal Commercial Concord range and is identified on the manufacturer's parts listing as the BNR 5.5 mm diameter injector.
Signs this part needs replacing
- Burner flame is weak, uneven or lifts away from the burner surface
- Appliance fails to reach its rated heat output or runs noticeably cooler than expected
- Sooting, discolouration or a yellow, lazy flame at the burner
- Ignition is unreliable or the burner extinguishes shortly after lighting
- Gas input readings at the meter fall outside the values given in the appliance data plate
Before you order
- Confirm the appliance model and serial number against the compatibility list, as injector bore sizes differ between variants and fuels.
- Check the existing injector marking or measure the bore to confirm 5.5 mm is the correct size for your appliance.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
