Storing Transporting, or Shipping
NOTE: If shipping, transport companies require fuel tanks to be empty.
1. Drain fuel tank.
NOTE: Some models have drain plug on underside of fuel tank. If so, remove drain plug to drain all fuel. If heater does not have drain plug, drain fuel through fuel cap opening. Be sure all fuel is removed.
2.Replace drain plug if provided.
3.If any debris is noted in old fuel, add 1 or 2 quarts of clean kerosene to tank, stir, and drain again. This will prevent excess debris from clogging filters during future use.
4.Replace fuel cap or drain plug. Prop- erly dispose of old and dirty fuel. Check with local automotive service stations that recycle oil.
5.If storing, store heater in dry place. Make sure storage place is free of dust and corrosive fumes.
IMPORTANT: Do not store kerosene over summer months for use during next heat- ing season. Using old fuel could damage heater.
Preventative Maintenance Schedule
Never service heater while it is plugged in, operating, or hot. Severe burns and electrical shock can occur.
