BSM: Back Shelf Manifold Asy. – (P/N 17461 with nozzles)
The BSM (P/N 17461) is comprised of three Amerex nozzles, positioned on a 45º angle and
spaced 12” apart. All nozzles are in the same plane of alignment and at the same height. This is
accomplished by the use of the Amerex manufactured manifold. The manifold is constructed from a
custom aluminum extrusion which is machined to the precise requirements needed to maintain
proper alignment of the nozzles. Connection to the nozzle branch piping may be made from either
end of the assembly. The opposite end of the assembly is to be plugged with a 3/8” pipe plug. The
manifold should appear as illustrated.
The BSM is to be used as an assembly of three nozzles and will carry a flow point value of one (1).
It is designed to extinguish fires located under the back shelf when they occur on the back three
burners of a six-burner range (15” x 42”) or the back portion of a griddle. It never takes the place of
the overhead nozzle, but simply provides additional agent to extinguish any and all fires beneath
the back shelf or salamander.
The same limitations apply to salamanders that are applied to back shelves.
When the BSM is used to protect a griddle positioned under a back shelf, the manifold is installed
on the centerline of the portion of the griddle covered by the back shelf or salamander. The
maximum amount of back shelf coverage allowed for griddles is 16”. The location of the overhead
nozzle is always to be to the front edge of the griddle. See required nozzle and aiming
requirements on the next pages for details on griddle protection.
The following pages are examples of manifold placement under several conditions of back shelf
use. The following schematics represent the only nozzle combinations permitted with a BSM.
Note : When using the BSM assembly for range protection only the Range Nozzle (14178) is
permitted in the overhead protection position as indicated on the schematics.
