Inspect the batteries
If the igniter filament does not get hot enough to ignite the wick and the igniter filament appears to be normal,
replace the batteries. For best results use non-alkaline batteries only.
Inspect the wick
Inspect the wick before each use to see if carbon has accumulated on the wick. If it has, perform the Carbon
Removal procedure described on page 9.
Check the height of the wick as described on page 7.
WICK MAINTENANCE
Carbon and tar will build up on the top of wick after the heater has been in use for a while. It is very important that the carbon
and tar build up be removed in order for the heater to burn properly, and in order for the heater to properly extinguish. After
every 2-3 tankfuls of fuel, check the top of the wick. If it feels hard and brittle, there is a build up of carbon on the wick. You
might even observe a coating of black carbon on the top of the wick. A wick that is in good condition will feel soft.
There are other checks you can perform to determine if there is a build up of carbon on the wick. If it is difficult to turn
the wick adjuster knob, if it is hard to ignite the heater, if it is difficult to obtain the proper wick height, these are signs
that there may be a build up of carbon on the top of the wick. To eliminate the carbon build up from the top of the
wick, perform the "Carbon Removal / Dry Burning" procedure outlined in the next section.
CARBON REMOVAL / DRY BURNING
The "Carbon Removal / Dry Burning" procedure creates a strong odor. Therefore, this procedure should always be
performed outdoors on a windless day. You can consider using a porch or other well ventilated area, but keep in
mind the fact that a strong odor is produced.
Carbon Removal Prodedure :
- As the fuel level in the heater approaches empty, continue to burn the heater without refilling. Once the
tank becomes empty and the flame starts to burn out, raise the wick to its maximum height and leave it
burning until it burns out completely. After it has burned out, wait 60 minutes, reignite the wick (use a
match, if necessary), and allow it to burn out again. Once it has cooled off, use a small brush or an old
toothbrush to remove any ash that remains.
- This procedure should remove the carbon from the top of the wick. The wick should feel softer. If some
parts of the wick still feel stiff, pinch these sections with a pair of small pliers. This will break up any
remaining carbon into small pieces. Once you have done this, add a small amount of kerosene to the tank
and repeat the "Carbon Removal" process again. After completing the "Carbon Removal" procedure, refill
the tank and wait at least 60 minutes for the wick to absorb enough kerosene before reigniting the heater.
You should perform the "Carbon Removal" procedure within 7 days of your first use of the heater. After that, the "Carbon
Removal" procedure should be performed whenever the build up of carbon causes the wick to become stiff. "CARBON
REMOVAL" SHOULD BE DONE EVERY WEEK DURING THE HEATING SEASON.
IT MAY BE NECESSARY TO DO IT MORE OFTEN DEPENDING UPON THE CARBON BUILD UP ON THE WICK.
CHECK THE WICK FREQUENTLY TO DETERMINE WHEN TO DO THE "CARBON REMOVAL" PROCEDURE.
