How Often
How To
Item
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.
