Re: I need to change the wick on my dk 23 corona kerosene...
What make and model is it? They are very simple to change,never heard of 1 "Not" lighting tho,unless you have water in tank and the wick sucked up the water...water don't burn,You can also raise the wick in their now if it has never been raised,as long as it don't have "riviet"looking things attached to sides of wick to fit it wick housing(Sears is good for that)If it a round or square heater it pretty much the same you have to remove the outer shell of heater, its always a good idea to dump out fuel first,at the base of wick their is usually 3 wing nuts or screw that hold wick Assembly in,after removing them you pull housing up to remove ,notice how the old one is on and remove and put new one on,when putting back in make sure wick fans out and goes to bottom tank,put back to gether and your done,most replacement wicks come with directions and height setting for the wick, Its not real hard as long as you pay attention

From your description, it sounds like the wick may need replacing or the tails of the wick are not hanging all the way down into the tank. And, therefore they are drying out. Thus, your flame gets low and eventually goes out. The only way to know is take the heater apart. If you're not comfortable doing that check with your local hardware stores, like True Value or Ace. many of these store do repairs on kerosene heaters and replace wicks. It can be a messy job, but someone has to do it.
well other then getting dirty and tearing it apart...... on the dk-12 when you install the new wick the black line needs to match up with the adjusting coller then you push the wick onto the teeth and assemble the hard part on mine is the piece below the wick that guides the wick in the bottom there needs to be a little slack so the wick can get raised and lowered. I hate to sound like I like ace hardware but from where I am at there guy there is great rebuilding these.
try bringing your wick up to the fully raised position and pinch and bend the wick toward the igniter until they line up right. I have two coronas one of which has a broken igniter due to wear and tear. If you open the little door,press down the start lever,and light the wick with a barbecue grill lighter,you can safely light the heater if lining up the wick fails.
You must be very careful and follow the instructions exactly on these wicks. The pins must be inserted into the holes on the wick holder. It is also easy to install the wick holder upside down. Look for a small up arrow on the side.
You must soak your wick for at least 30 minutes, preferably 1 hour. I know it's tempting to light it right away, especially when you are freezing, but you must wait. Wicks work by using capillary action. The fuel must have time to soak in properly.
All wicks are NOT created equal. Buy good ones, under no circumstances should you buy the ones that Walmart sells. They **** and you will be changing it in a day or two. Home depot sells a decent one, but for the really good ones visit Miles Stair wick shop. He also has some good info to deal with condensation and moisture problems.
Also note these heaters will not work if they are dirty. They must be absolutely clean of all dirt and debris, every single part. Especially the parts that come in contact with the wick.
Regular maintenance, good wicks and good fuel will keep these heaters working.
