What it is
The Ideal 176558 is an LPG orifice kit, listed by the manufacturer as an injector. The orifice is marked 3.4 and is the component that sets and meters the gas flow rate reaching the burner on an LPG-fuelled appliance. It is used on Ideal Commercial appliances, principally the Evomax range.
Signs this part needs replacing
- Gas rate at the appliance cannot be set to the figure in the manufacturer's instructions
- Combustion readings drift outside the expected range for LPG, or CO readings rise
- Sooting, a lazy or unstable flame, or visible burning at the burner that does not match the appliance's normal pattern
- Repeated ignition faults or lockouts on start-up
- The orifice is blocked, damaged or has been drilled or altered from its original marking
Before you order
- Confirm the appliance model and GC number, as the same appliance family can use different orifice sizes for different gas types
- Check that the 3.4 marking matches the orifice size specified for the appliance and gas type being worked on
