909010489 Genuine LPG Injector Jet 0.68mm for Smeg Gas Cooktops and Cookers, Smeg Burner Gas Jet for LPG

909010489 is a genuine Smeg LPG jet with a 0.68mm orifice. Also called an injector, a jet screws into the gas supply under a burner and controls exactly how much gas flows through to it. LPG jets are much smaller than natural gas jets for the same burner, so the gas type and the size must both match. Check which burner on your Smeg takes a 0.68 LPG jet before ordering.

Why the right gas jet matters on a Smeg cooktop

The jet sets the gas flow, and the burner is designed around it. A jet that's too large for the gas type gives a big, lazy yellow flame that leaves soot on pots and can produce carbon monoxide. Too small and the flame is weak and may lift or go out. Jets can also partly block with spilled food or debris, giving a small or uneven flame on one burner. New jets are needed when converting a cooktop between natural gas and LPG, or when a jet has been damaged by the wrong tool. Never drill out a jet to make it bigger.

Who should fit gas jets

Changing jets is gas work, and in Australia it must be done by a licensed gas fitter, who will also adjust the simmer settings, test for leaks and update the gas type label when converting. Turn off the gas at the appliance isolation valve or cylinder before any work begins, and never use the cooktop with a jet missing.

Questions about this part

How many jets do I need for my cooktop?

One for each burner that uses a 0.68 LPG jet. Different burners take different sizes, so a full conversion usually needs a set. Your gas fitter or the Smeg installation manual will list the jet size for each burner.
