Fire rated drywall over wood stove?

Currently there is brick under and on two sides of the walls with drop ceiling on the ceiling. This is in a finished basement. I'm removing the ceiling and it's getting drywall instead so my question is should this be type-x drywall or will normal drywall do? I can't imagine a drop ceiling would be to code but regular drywall wouldn't be...?

Do you have the specs on the wood stove?
That will list clearances
My last house had normal sheetrock over the stove
I think the issue would be if the wood stove was raised up really tall & there was onky maybe 24" clearance above the stove
For most stoves at/near floor level I do not think normal sheetrock is a problem

Most stoves require at least thirty inches of clearance to combustible walls, furniture, etc.
With heat shields on the stove this distance can be reduced
Stove at my last house I bricked around the area
It had a passive heating wall behind the brick
As the wall heated up cooler air would be drawn from under the stove platform & up behind the stove between the brick wall & cement board wall
Then out vents at the top of the brick wall

As far as I know, drywall is combustible.
Maybe not the gyproc itself, but the paper definitely is.
Your clearance to combustibles is what you need to look at and each stove is different. Normal drywall is okay to use as long as the ceiling isn't too close to the stove. 5/8 drywall will still have that combustible paper on the face. Goto a concrete board if you are really worried about it. Paint it up......but is paint combustible?
