Heat resistance on hearth

[Brindle]

Hi folks, have someone who wants a hearth tiling (quarry tiles). A pot belly stove will be on top of them. Will a Flexible rapid (or normal setting) be affected by any heat displaced from the stove. I assume it will be fine, but thought I'd check with the forum.
Thanks
Bob

Rapid set is fine

Cheers Gaz, and I read on another thread that standard rapid is better heat wise than flex.

Thanks a lot
