Any new appliance
should be treated with respect. Before use, all exposed
metal surfaces should be given a coat of good automotive
polish to seal the pores of the enamel finish and help
preserve the finish. Before storage in late spring, they
should again be cleaned up and given a coat of polish.
Polish is cheap, and you paid good money for the
appliance. Why not keep it in good condition, as it only
takes a few minutes a year to do it?
Familiarize
yourself with the details of the unit. Carefully remove
the burner unit and raise the wick. Note the appearance
and height of the wick. With all of the kerosene heaters
with which I am familiar, the wick should protrude about
inch at maximum height, and completely retract into its
slot when in the off position. (With radiant units, the
grill can be opened and the burner removed. With
convective units, three perimeter screws around the base
of the tower must be removed, then the circular tower
carefully lifted straight up and removed to gain access
to the burner unit.)
Kerosene stoves with normal wicks
that rise should have the wick trimmed to the height of
the trimming guide visible when the catalytic converter
is removed. The saturated wick design used on some
Butterfly stoves (#2413, 2416, 2418, etc) is unique in
that the wick itself does not move, but rather the fuel
flow is what controls the heat output. The
catalytic converter of these Butterfly stoves is
virtually identical to all other catalytic converters, so
the illustration below is graphic enough to show you what
the inside of a catalytic converter look like. Click to

The reason for
the exercise mentioned above is because it will become a
regular ritual, so you might as well see how easy it is
to do...the units are all designed for this. Reassemble
the unit in the reverse order.
Initial
Seasoning
Your unit,
regardless of type or style, is now ready for initial
seasoning. Take the unit out of the home, say to a garage
or covered patio for ventilation. This will protect it
from strong drafts and from rain for this session. Pour
at least a half gallon of kerosene into the tank, then
let it be for at least a half hour so the wick can become
fully saturated.
After the half
hour, light the unit with the wick set at the maximum
height, and let it burn in that position until the burner
is completely red and flames of 1" appear above the top
of the burner. Then turn the wick down about half way
between the high and low settings and let it burn. During
this initial burning, all of the preservative oil on the
combustor unit is burned off (smelly), the metal becomes
properly annealed, the enamel surfaces are fully cured,
and the entire unit "conditioned" to its designed
configuration for use. After hours of burning, the flames
will begin to die down and the upper part of the burner
unit will change color from red to black. Now is the time
to turn the wick to its maximum height and let it burn.
It will take at least another hour before the flames die
out, and then the tar residues on the top of the
fiberglass wicks will burn off (very smelly).
The reason for
this initial seasoning burn being done at a reduced wick
height is because the new wick is in pristine condition,
so its capillary action is at maximum capacity. By
burning the wick dry during the first burn, the wick
itself becomes seasoned and will last considerably longer
in use.
Your kerosene
appliance is now ready to give you years of odor free
performance. Inexpensive kerosene appliances in
particular will perform much better if properly
seasoned.
