30" X 48" GRIDDLE
The schematic above shows the protection method on two different size griddles (30”x42” & 30”x48”) that
are positioned under a back-shelf. Note that the shelf extends 1” beyond the center of the griddle (16”)
and covers the entire width of the griddle, all which are within the parameters of the listing. Also,
recognize that the centerlines of the manifolds are congruent with the centerline of the hazard covered by
the back-shelf. Each manifold must be located on the centerline of the hazard area it is to protect.
The P/N16416 nozzle plus a BSM (back-shelf manifold) will protect griddles up to 30”x42” maximum, with
a back-shelf that covers no more than 16” of griddle. Total flow point value is 2 flow points. The
overhead nozzle must be located on the front edge of the griddle aimed at a point 7” back from the center
of the hazard area on a straight line from the nozzle to the center of the hazard.
The P/N14178 nozzle plus a BSM (back-shelf manifold) will protect griddles up to 30”x48” maximum, with
a back-shelf that covers no more than 16” of griddle. Total flow point value is 3 flow points. The
overhead nozzle must be located on the front edge of the griddle aimed at a point where a straight line
from the nozzle to the center of the griddle crosses an 11” square placed over the center of the griddle.
