WARNING:

causing property damage, personal injury or loss of life.
A. This appliance does not have a pilot. It is equipped with an ignition device which automatically
lights the burner. Do not try to light the burner by hand.

the floor because some gas is heavier than air and will settle on the floor.

• Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's
instructions.

hand, don't try to repair it, call a qualified service technician. Force or attempted repair may result
