I should think you have the wick up to height. light the wick then check on
it after about 10 mins, the flame tends to get larger as the stove warms up,
you want a nice BLUE flame with no sign of yellow.
I used to be able to trim the wicks just once a week, and I had 6 double
burner stoves burning , sometimes 24 hours a day if it was cold.
