I am trying to remove my single wall telescoping pipe so I can take it outside to re-paint it, This is obviously inside the house. My pipe comes straight off the top of the stove and up through the ceiling kit. It consists of 2 4' sections (top and middle) and then the telescoping section which is also 4'. My issue is when lifting the pipe up it only telescopes about 1/2 inch leaving at least another 1/4 to 1/2 and inch left. I do not want to damage anything by torquing it too much and was wondering if there were any tricks to maybe lubricating the telescopic sleeve or something on those lines to help make it slide up easier? I would also like to mention that when the installer hooked up the pipe, he put a self tapping screw through the telescopic sleeve to keep it from rising up when the stove is running. The screw created a pinch. I feel like I pried it out pretty good, but was very conscious about prying to hard and puncturing the pipe.
Assuming I can get the pipe off, is it advisable to remove all sections before sanding and painting or is it ok to leave them all attached and work on it as one big piece, Leaning towards taking it all apart for eases of movement, but wanted to hear what others typically do.

Thank you
 
Can you move the stove out of the way while the pipe is raised. Once the stove is moved, just drop the pipe.
 
It's not a lube issue, it's a creosote issue. Creo is built up on inside face of outer tube, preventing inner tube from sliding down inside it. You can either follow Limestone's suggestion, or brush the tube first (Sooteater up thru stove is an option).
 
I will give the cleaning a try. I could move the stove with some help (weighs nearly 500 lbs) but the pipe is still in the flu outlet and would put stress on the whole pipe if it did not release. Thank you for the suggestions.

The next step would be to lift from the top, but that would be much more work.
