Lighting a Bunsen burner
Close the needle valve most of the way, leaving the valve only slightly open. Connect the tubing to the burner's gas inlet nozzle and to the gas outlet nozzle at the bench. Turn on the source of the methane gas. Slowly turn the needle valve
a small amount to supply gas to the burner.
To ignite the gas using a striker, hold the striker at the side of
the outlet of the burner tube and squeeze and release until a spark
ignites the flame. A match can be used to light the burner by slowly
bringing the lighted match up from the bottom along the side of the
burner tube until the flame ignites.
