Before proceeding with the conversion,shut off the gas supply to the appliance prior to disconnecting the electrical power.
Be careful when working on the handling of sheet metal parts of your gas range.
To avoid burns, do not convert gas types until the cooktop surface has cooled.
Remove grates, burner caps and burner heads.

Burner Cap
Burner Head
Burner Body
Nozzle
Remove the brass nozzle in the chimney of each burner using a 5/16” or 8 mm nut driver.
Replace it with an appropriate nozzle for the new type of gas (see "Before Converting the Gas”).

To prevent leakage, make sure the nozzles are securely screwed into the gas supply tubes.
Place each burner head on the burner body. Position the relevant burner cap exactly on top of the burner head.

If the size of low flame (simmer) seems not normal after the gas conversion, see "Surface Burners" section to adjust the low flame (simmer) setting.
