I have a Duravent Direct Vent flue for a gas stove in a woodframed “chimney”. I need to replace the chase cover, so the top section of the flue needs to be separated from the rest so I can slide the chasecover off and on. I tried twisting and pulling, but the sections don’t seem to want to separate. Is there a trick to this?

I assume you know they lock together with a bayonet lock.
Dan, that's what I thought too. From the looks of it there are 4 indentations where the pipes connect, but from the way those indents look I don't see how they could be bajonet locks. I'll try again in the morning.

twist them till the seams line up...they will always seperate in that configuration....
The way I hear this, he is having a hard time twisting the parts in the first place.but if this was not put together with concern for seam alignment, that suggestion would not help. It only needs to untwist about 1-1/2" to free up the lock joint, but to do what you say copuld have him trying to untwist as much as 330°

I hope he doesn't do that. Would be pretty funny to be in the house when the wood stove starts turning around..;)
after it has been together and used a while, some creosote on the inside can act like a glue and you have to be more forceful.
tapping with a hammer all the way around the joint a couple times can help break that seal a bit.
But I am not sure you need to separate the pipe itself. Just taking the cap off should get you where you want to go.
Also, check to see if there are pop rivets or sheet metal screws in the joints to stabilize.
only other thing I can think of is some idjit used some silly cones in the joint
