LISTINGS & APPROVALS
Exposed Installation - General (UL & C-UL)
In accordance with the UL and C-UL Listings, TYCO CPVC 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 ar- eas such as small closets and bathrooms. Where sprinklers are not re- quired, and when approved by the authority having jurisdiction, it is ac- ceptable 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 di- rectly 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.
