Never use gasoline, naphtha, paint thinners, alcohol, or other highly flammable fuels. Do not use heavy fuels such as No. 2 fuel oil or No. 2 Diesel. Using heavy fuels will result in: • clogged fuel filter and nozzle • carbon build up on spark plug • the need of non-toxic anti-icer in fuel during very cold weather IMPORTANT:Use a KEROSENE ONLY storage container. Be sure storage container is clean. Foreign matter such as rust, dirt, or water will cause the flame- out control to shut down heater.
