Solvent cements used shall be those referenced in Harvel Plastics,
Inc. Installation Instructions (such as Spears FS-5 or equivalent),
which meet or exceed the requirements of ASTM F656 and ASTM F493,
and shall be approved by the National Sanitation Foundation (NSF)
for use with potable water. Socket type joints, sizes 3/4”
- 3”, shall be made up using the One-Step solvent cement joining
method. The solvent cement joining method chosen shall be applied
in strict accordance with the appropriate procedures as outlined
in Harvel Plastics Installation Instructions.
MAINTENANCE:
Maintenance shall be in accordance with the Standard for Inspection,
Testing, and Maintenance of Water Based Sprinkler Systems as defined
by NFPA 25.
LIMITATIONS:
• CPVC systems are intended for use at a maximum working pressure
of 175 psi and ambient temperature of 150°F.
• CPVC systems shall employ sprinkler heads having a maximum
temperature rating of 225°F or lower, regardless of type.
• CPVC products shall be installed in wet pipe systems only.
• Air or compressed gas shall never be used for pressure
testing.
• CPVC sprinkler systems shall be hydrostatically tested
for 2 hours at 200 psi, or 50 psi in excess of the maximum working
pressure when the maximum working pressure exceeds 150 psi. Lines
shall be slowly filled with water and the air bled from the highest
and farthest sprinkler heads before test pressure is applied.
• Only Teflon® tape or a thread sealant specifically
approved for use with Harvel® CPVC Fire Sprinkler Products shall
be used in making threaded connections.
• Where freeze protection is required, only glycerin based
anti-freeze solutions shall be used and installed in accordance
with NFPA 13. Do not use glycol base anti-freeze solutions or contaminated
glycerin solutions.
• CPVC is not approved for use in combustible concealed spaces
where sprinklers are required to protect these areas as defined
by NFPA 13, unless certain specific application sprinklers are installed
per their listing. Refer to Harvel’s current Installation
Instructions for additional information.
• CPVC sprinkler piping may be installed in a plenum space
adjacent to, but not over, openings in the ceiling such as open
ventilation grills, and require the use of schedule 80 fittings
for use on 1 _” and larger pipe sizes. Refer to Installation
Instructions for additional detail.
• Minimum protection when installed “concealed”
shall consist of: 3/8” gypsum wallboard or drywall, suspended
membrane ceiling panels weighing not less than .35 pounds per square
foot, or 1/2” plywood soffits. Minimum protection for NFPA
13R and 13D systems may consist of 1/2” plywood.
• Harvel® BlazeMaster® pipe is Listed for use in
exposed applications with certain limitations. When installed without
protection, “exposed” pipe is to be installed beneath
smooth, flat, horizontal ceiling construction. Exposed categories
include: standard coverage and residential pendent and sidewall
sprinkler applications, light hazard extended coverage and residential
sprinkler pendent and sidewall sprinkler applications, use in unfinished
basements with exposed solid wood joists, light hazard upright quick
response sprinklers, and system risers (in 13R & 13D occupancies).
Refer to Harvel’s installation instructions for specific sprinkler
head temperature ratings and spacing requirements. The product must
be installed in strict accordance with NFPA 13, 13D, 13R and Harvel’s
current CPVC Fire Sprinkler Piping Products Installation Instructions
(HFS-3).
• Harvel CPVC Fire Sprinkler Products must be installed in
accordance with Harvel’s current installation instructions
(HFS-3).
