STORING, TRANSPORTING, OR SHIP-
PING
NOTE: If shipping, transport companies
require fuel tanks to be empty.
1. Drain fuel tank.
NOTE: This model has a drain plug on
underside of fuel tank. Remove drain plug
to drain all fuel. Be sure all fuel is removed.
2. Replace drain plug.
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 and drain plug.
Properly 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

IMPORTANT: Do not store kerosene over
summer months for use during next
heating season. Using old fuel could
damage heater.
Never service heater while it is plugged in, operating, or hot. Severe burns and electrical shock can
occur.
