How to light a garden citronella torch?

Question:I purchased ten citronella torches but am a bit puzzled about lighting them. I have the citronella fuel. The top of the torch has a black tube with a string and cap attached to it. Not exactly sure how to use this!! Any tips would be really helpful! Thanks!

Answers:
Unscrew the attached cap. Underneath it will be another cap with a slot and a wick sticking out of the slot.
Unscrew the cap with the slot and put the citronella fuel in the canister
Replace the slotted cap and wick. Pull about an in of wick out of the top side of the slotted cap.
Replace the canister in the torch stand.
Light the wick.
Should burn 4 to 6 hours
