Is PVC considered combustible?

[Bill Smith]

I'm a little wiped out and can't remember - In regards to clearance from a single wall w/h vent - is pvc considered a combustible material? Thanks in advance.

Thanks Robert;

I got home last night after the inspection (house built in 1940 with lots of additions - 4 crawlspaces, 3 attics, 3 ac systems, 5 heating zones, 7 sub panels) and I was completely spent. I appreciate the response.
