Do not store or use gasoline or other flammable vapors and

liquids in the vicinity of this or any other appliance. Do not

attempt to start the burner when excess oil has accumulated,

when the furnace is full of vapor, or when the combustion

chamber is very hot.
For use with grade 1 or 2 fuel oil. Do not use gasoline,

crankcase oil, or any oil containing gasoline!
Never burn garbage or paper in the heating system and never
