I think that is the attic insulation shield. If so, it goes on the attic side of the support box if the top of the support box ends before the roof. The purpose is to stop blown-in insulation or any other debris from falling into the support box which must remain clean inside. We haven't seen pictures of the chimney part of the install yet so I am not sure if it's necessary for your install.
Thank you, The ceiling box is just sitting in the ceiling opening. Im going to have to attach everything from the roof side. I wasnt able to push it into the ceiling as far as I want (3" down from the ceiling) which has me thinking that the box is hitting the roof decking. I wont know for sure until I get the roof opening cut and have a look inside. If the box sticks out past the shingles I think I'm supposed to bend the edges of the box over the rooftop and nail down. If it doesn't go that far and I have room to install the insulation collar, Ill slip it on. Ill send pics.
Thanks again for all your help~

If you got the kit, it comes with 2 adapters. One is for single-wall stovepipe (red x) and the other is for double-wall (green circle) DVL stovepipe. I think that one end of the DVL adapter is 1/8" larger. That end goes into the support box.

Here is what I ended up with.

Looks kind of unfinished to me but if this is the way it's meant to be I guess it's okay. I have the other DVL adapter on its way. Is that little eighth inch of space at the top of the pipe enough for the air to move? Just wondering if I should stick with this adapter or use the one that's on its way. Supposed to be 72 degrees tomorrow so I took off of work I'll get the chimney installed and post some pics for you guys to see

Quick question, The DVL adapter for connecting the DVL to the ceiling box arrived yesterday. The one that came with the kit is installed ,see above. If that is correct and sufficient why is there another type available? Is it Superior in some way? I have about 1/8" gap between the top of the DVL and bottom of the ceiling box where as the newly arrived adapter has holes all around it. Just wondering if it is a better choice or should I just send it back for a refund. Thanks~

completely forgot about the fresh air intake while building the hearth. Im going to have to cut a hole thru the hearth and then down thru the floor. I plan on using flex line, like for a dryer vent with some metal clamps then paint it with high heat paint. Is it ok to leave the intake side of the line under the house, below the belly paper, or should I run it out thru the skirting? Thank you~

Belly paper is fine since its outside the air envelope of the house, put a screen on the end to prevent critters

OK, thank you, saves me from running extra dryer vent :) In my reading people are saying you could get bad air or "moldy" air but I think Im ok.

The fire just want oxygen to burn, since it’s direct connect to the stove it should be pretty static for all times since the door is shut and the stove is considered air tight (to an extent)

nice! thank you very much for the colored picture :) believe it or not that made all the difference for me. I will to dry fit it today. I have scrubbed the install for today. I think its way too cold for the silicone and shingles. I just know id end up breaking at least one shingle, smh. Next Thursday, if the weather man isn't wrong haha, its supposed to 63 degrees. I'm not a gambling man but I feel better about the roof work in warmer temps. Im just going to regroup, reorganize and get my thoughts together till then. Oh and cancel that Amazon order ;) thanks again~
As said, that thing on the stove is to close off the top of the support box poking up into the attic.

Is a “square-to-round collar”. Providing you install as directed, this allows the top of the box to act as an attic insulation shield. Surrounding attic insulation should not be higher than the top of the box. In a perfect world, you would have minimum of 3” freeboard. For example, if portion of box poking up is 18”, surrounding insuwould be no deeper than 15”.

You don’t want attic insulation spilling into the top of the box and falling down alongside the chimney within.

You can use the box as an attic insulation shield as long as you have a storm collar to cover the top of the box. It can't be left open.
