UL - Design Criteria
•
Refer to Table A for Model, Nominal Assembly Length,
and Sprinkler Reducer combinations
• Wet-pipe systems only
•
The hose and ttings have limited exibility and are
intended for direct connection to sprinklers in accor-
dance with NFPA 13, 13D, or 13R
• Maximum service pressure of 13 bar
•
Maximum K80 (5.6K) for 1/2 inch NPT sprinklers or
maximum K160 (11.2K) for 3/4 inch NPT sprinklers
•
Maximum ambient temperature of 107°C for Model
YB25 and YB28, or maximum ambient temperature of
148°C for Model YN25
•
These connections are designed for use in ceilings
with grids that meet ASTM C 635 (Standard Specifi-
cation for the Manufacture, Performance, and Testing
of Metal Suspension Systems for Acoustical Tile and
Lay-in Panel Ceilings) and ASTM C 636 (Standard
Practice for Installation of Metal Ceiling Suspension
Systems for Acoustical Tile and Lay-in Panels) refer-
enced by IBC. The three structural classications are
the following: Intermediate-Duty Systems and Heavy-
Duty Systems. These connections have been approved
for use in all Intermediate-Duty and Heavy-Duty struc-
tural classications
