I recently had some spray foam installed in the attic and the crew put it right up against the chimney pipe. Is this a concern? Should I carve out 2" and replace with something?

It says 2" from combustible material. Is spray foam insulation combustible? And if I need to carve away the insulation, that means a insulation radiation shield? But won't that let in cold air to the attic?
