"FOR YOUR SAFETY READ BEFORE OPERATING"
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."

some gas is heavier than air and will settle on the floor."
Warning if you smell gas
No naked flames, no smoking!
Avoid causing sparks, do not switch on or off electrical equipment or lights
Open windows and doors
Shut off the main gas supply
Warn occupants and leave the building
After leaving the building alert the local gas supply company
