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 safety
control to shut down heater. Foreign matter may also require fuel system to be
cleaned frequently.
