Notice
FOR USE AS A REPLACEMENT OF MODEL G4A SPRINKLERS
NOTE:
1. Testing has shown that use of a “nipple extension” will not affect the listing of the sprinkler.
2. For RETROFIT installations, per
NFPA 13 (2010) section 8.15.19.4,
“which allows the use of nipples as the same pipe
thread size as the existing outlet when revamping existing systems”.
3. Do not exceed 8-18 ft-lbs of torque during installation.
