A general rule of thumb is you can run CPVC anywhere sprinklers are not
required. If you want to run CPVC in an area where sprinklers are
required, you have to use sprinklers that are specially listed to allow
CPVC in those spaces.
If you had an office building that was framed in steel, then you could
use CPVC.
Your case is very similar. You want to run the piping in a
non-combustible area and supply pendent sprinklers in the ceilings. I
don't believe that violates any listings of the CPVC piping.

I have an interesting question to ask of everyone here. I am being asked to
install an NFPA 13, non-residential sprinkler system in a small, new building
that will be constructed with wood. However, the wood trusses will consist of
fire rated lumber with a flamespread rating of less than 25, which will not
require sprinkler protection since they would considered to then be
non-combustible, or at the worst, limited combustible.
With that being said, could you then install CPVC piping in these concealed
areas without also having to use the specially listed concealed sprinklers
(such as the CC1, CC2, HIP, BB1, etc.) heads that Tyco makes ?
Remember, you can only install CPVC in an attic or a combustible concealed
space if you also use those specially listed heads but if the area is
technically not combustible I would say that you could use CPVC just like if
you were using CPVC above an gyp board ceiling in an office for example - if
you take the listing literally.
What does everyone else think ?
