Bruce,
The Hilti FS-One Installation Instructions submitted on May 2, 2007 still do not contain
the listed and tested fire stopping assemblies for each type of penetration. In the
installation instructions under "Notice About Approvals", it refers you to the UL Fire
Resistance Directory or Hilti Firestop Manual for the listed and tested assemblies. Those
are the assemblies that you need to submit to us for review. We need one assembly for
each type/size of penetration (plastic pipe, copper pipe, duct, etc.). Above is a link to
the Hilti website containing several listed and tested assemblies using FS-ONE which may
help. They are organized by type of penetration. You may want to contact the Hilti
Representative -- they are usually helpful. Please submit 2 copies of each assembly.
Sincerely,
Ann Bullis
Assistant Building Official
