CARE AND MAINTENANCE
As with any good appliance, preventive as well as corrective maintenance is occasionally required. Please
read the following section carefully in order to enjoy the greatest benefits from your heater.
INSPECTlON OF THE WlCK
NOTE: One of the simplest but also the most important components of your heater is the wick.
With proper attention, the wick will last at least one heating season and, depending on the quality of
the fuel used, possibly longer, it helps to perform routine maintenance operations of the wick.
1. lndications that the wick may need attention are:
ⅷ low flame
ⅷ
tar deposit on the top edge of the wick
ⅷ difficulty in turning the wick adjuster knob
ⅷ a flickering or dying flame
2. Clean the wick by burning dry as follows:
1) When the fuel gauge indicates empty, but the heater is still burning, raise the wick to its highest
position and allow the flame to consume the remaining fuel in the tank.
NOTE: Burning the wick dry can at times create odors. For the burning dry procedure, remove your heater
from the living area of your house into a well-ventilated area such as a garage or even a sheltered
area outside. If you burn the wick dry outside, be sure that the heater is not exposed to strong drafts
during the procedure.
2) After the heater has cooled completely, remove the heater cover as described in items 1 and 2 of the
next section.
3) Remove any residue from the wick with a small brush such as an old toothbrush. Cinders or soot in the
burner around the wick may be vacuumed away. Be careful when removing such material from the wick
with a brush, to do so gently so as not to tear the top surface of the wick.
4) Remove any tar deposits on the top of wick adjuster and primary air tube using a scraper.
NOTE: When good wick performance is no longer achieved by the burning dry process, it may be
necessary to replace the burned wick with a new one.
5) Before reassembling the heater, take a few minutes to wipe the parts with a soft cotton cloth or paper
towels.
6) Reassemble the heater, following directions in item 11 of the next section.
NOTE: If the flame is still low after cleaning the wick, the wick may contain some water. It is then necessary
to replace the wick and empty all kerosene (paraffin) from the fuel tank. Dry the tank thoroughly and
refill with fresh, pure kerosene (paraffin).
INSPECTION OF THE IGNITER COIL (EVERY TIME)
If the wick does not igniter or is hard to ignite, check if the igniter filament is broken.
If the igniter coil is found to be defective, replace as described on page 14.
