gas fireplace code questions

I have a Heat-n-glo gas fireplace I'm installing in a remodel. It vents straight up through the ceiling and then through the roof. There's about 1 foot from the ceiling to where it passes through the roof...this is the attic space. I boxed out with 2x6 around the flue and installed a metal firestop on the top portion (10" x 10"). So, from the inside looking up, you can see the 2x6 box and firestop. The drywall goes up to the box I made. Above the firestop is blown insulation, but none of it is touching the flue...that I know about.

So, is this all acceptable code wise? Do they usually drywall up to the flue on the inside? Seems like a lot of heat could escape up and through that area since there is no insulation. Does the drywall need to be taped and mudded at the seams?

I live in Minnesota.

the firestop is usually two sided or designed to drop down into the room. You could also maintain the required distance around the pipe with sheetrock and finish it with a collar. Yes sheetrock is fire resistant but the paper on it is not.

It's in the teens out right now. Looking at the firestop from below I can see a whole bunch of condensation taking place. I haven't caulked around the firestop yet. But this is the only barrier there is between the inside and the attic space. Seems like a terrible waste of heat.

Wondering if I'm missing something. Should I drywall up to the flue as well and then caulk that?

Anyone know where I can get some answers for this?
