Because the ignitor is wet.
because the fire will burn up the shelf.
Then you might hurt yourself
The obvious answer is - because they will ignite !
An automatic spark ignition (igniter) works by allowing a spark to come on at the same time the gas comes on. The spark ignition module is inside the burner area. The burner should then light.
An oil burner typically ignites using an electric igniter or a spark igniter. The igniter generates a spark or heat that ignites the oil to initiate combustion.
A Bunsen burner striker is a tool used to ignite the gas coming out of a Bunsen burner. It produces a spark that ignites the gas, allowing the burner flame to be adjusted and controlled for heating purposes in the laboratory.
A flint is commonly used.
The correct sequence of steps for lighting a Bunsen burner is: B. Open the gas adjustment at the base of the Bunsen burner first, followed by C. Connect the gas supply. Finally, A. Apply the spark above the barrel of the Bunsen burner to ignite the gas.
No. You can not light a Bunsen Burner by turning on gas and oxygen. It takes a spark. (Actually, it takes a certain temperature to get the reaction started. The spark simply brings the material extremely near the spark up to that temperature.)
Screw out spark plug then screw in non fouler then screw in spark plug in non fouler.
Copper sulfate does not extinguish a lighted splint. When a lighted splint is exposed to copper sulfate, the flame may change color due to the presence of copper ions, but the splint will continue to burn as long as there is sufficient oxygen available for the combustion reaction to occur.
A burner is typically ignited using a spark produced by a piezoelectric igniter or a match or lighter. Gas burners may also have a pilot light that remains on to ignite the burner when needed.
