OBC states to cove unless 3.2.5.14 (5) is meet

according to Blazemaster

Exposed Installation- General (UL & C-UL)
In accordance with the UL and C-UL Listings, BlazeMaster pipe and fittings
may be installed without protection (exposed), subject to the following
additional limitations:
Note: NFPA standards permit the omission of automatic sprinklers in areas
such as small closets and bathrooms. Where sprinklers are not required,
and when approved by the authority having jurisdiction, it is acceptable
to install BlazeMaster products exposed in these areas.
Note: Where piping is required to be mounted directly to the ceiling/wall,
the use of listed hangers for thermoplastic sprinkler piping mounted directly
to the ceiling/wall is permitted. The resulting clearance between
the pipe and the ceiling/wall as a function of using the listed hanger is
acceptable.

Read Page 10 an more for the installation

The exposed installation is more involved

The one question is this a NFPA 13 , 13D or 13R install can change the requirements
