Install in accordance with NFPA 13, latest edition.
Install hangers to provide minimum 1/2 inch space between finished covering and adjacent work.
Place hangers within 12 inches of each horizontal elbow.
Use hangers with 1-1/2 inch minimum vertical adjustment. Design hangers for pipe movement without
disengagement of supported pipe.
Support vertical piping at every floor. Support riser piping independently of connected horizontal piping.
Where several pipes can be installed in parallel and at same elevation, provide multiple or trapeze hangers.
Provide copper plated hangers and supports for copper piping sheet lead packing between hanger or support
and piping.
Prime coat exposed steel hangers and supports. Refer to Section 09910. Hangers and supports located in
crawl spaces, pipe shafts, and suspended ceiling spaces are not considered exposed.
Slope piping per NFPA 13 and arrange systems to drain at low points. Use eccentric reducers to maintain top
of pipe level.
Prepare pipe, fittings, supports, and accessories for finish painting. Where pipe support members are welded
to structural building framing, scrape, brush clean, and apply one coat of zinc rich primer to welding. Refer to
Section 09910.
Do not penetrate building structural members unless indicated.
Provide sleeves when penetrating footings, floors, and walls. Seal pipe and sleeve penetrations to achieve fire
resistance equivalent to fire separation required.
When installing more than one piping system material, ensure system components are compatible and joined
to ensure the integrity of the system. Provide necessary joining fittings. Ensure flanges, union, and couplings
for servicing are consistently provided.
Die cut threaded joints with full cut standard taper pipe threads with red lead and linseed oil or other non-toxic
