PORTABLE FORCED AIR HEATERS

®

STORING,
TRANSPORTING,
OR SHIPPING

Note: 

If shipping, transport companies re-

quire 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 dur-
ing 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 heating
season. Using old fuel could damage heater.
