sealing chimney tee with tee cap

i have a fireplace on the first floor. directly above it on the second floor a franklin stove was installed and hooked into the chimney via a tee. i have removed the stove ( i live in tampa, florida and would rather have the room space) and i want to close off the tee. i want to continue to use the main fireplace 10-20 times per season so i want to seal up the tee and make sure it's safe.

can i just slap on an 8" tee cap and seal it with chimney adherent and put some drywall in front of it. should i put some type of insulation between the end of the tee and the drywall that will rest against it? this part of the chimney is probably about 10-12 feet above the main fireplace so i don't expect it to get very hot.

any help would be greatly appreciated so that i don't burn the house down!

What you propose is legal. Key is all areas sealed with fire-proof caulk or cement. Use screws on the cap and seal properly.

Hope this helps!
