Wick replacement should be performed on a completely cool heater after the tank is empty and the remainder of the kerosene in the heater has been burned off.
Step 1
Remove the batteries from the heater.
Step 2
Remove top guard by unscrewing 4 screws, or in newer models just by releasing it from the main grill.
Step 3
Take off the top plate.
Step 4
Lift the burner assembly out of the heater.
Step 5

Step 10
Lift off the entire Wick Assembly.
Step 11
To remove the wick from the adjuster, fold it and slide it out. Caution: the teeth holding the wick are very sharp.
Step 12
The replacement wick has a black line. Fold the new wick and slide it into the adjuster. The black line on the outside of the wick should match the bottom edge of the adjuster. Press the wick against the teeth inside the adjuster to obtain a firm grip. Start at the bottom row of teeth and slowly work your way up in a circular motion.
Step 13
Ensure that the gasket is still in place on the burner tank.
Step 14
Slide back the wick and adjuster mechanism on the draft tube of the heater tank, making sure the wick fits evenly in place.

Step 16
Position the adjuster shaft to the front of the heater and reinstall the wick adjusting knob.
Step 17
Check the wick movement by rotating the knob clockwise and counter-clockwise. The wick should move up and down freely.
Step 18
Snug but do not tighten 4 wing nuts on the mounting studs.
Step 19
Raise the wick a little and check for correct clearance between wick holder and draft tube (all around), or for correct clearance use 7/32 dia. drill bit.

Evenly tighten wing nuts in several steps.
Step 21
Check height of wick, 3/8 inch above rim of wick adjuster.
