Back shelf – What to do?
The use of a back-shelf presents a problem to the designer of a kitchen fire suppression system for it is
an impediment to the delivery of the wet chemical to the potential fire hazard. The same is true for
salamanders that are mounted over an appliance requiring protection. A shelf or salamander that
extends over the appliance not only prevents proper delivery of wet chemical but also is a fire hazard. All
too often, these shelves become storage places for items such as paper plates, doggie bags, or
flammable food preparation liquids. The overhead application of the wet chemical from an Amerex
Restaurant Fire Suppression System would be of help in extinguishing a fire occurring in items placed on
a back-shelf, but that is not the intended hazard for which the system was designed. The shelf or
salamander prevents agent, from an overhead nozzle, from reaching the actual cause of fire in the
appliance.
Amerex has developed the only real world solution to this problem. When a shelf is installed over a
range or a griddle, a small manifold of three special nozzles provides fire suppression protection. The
BSM (back-shelf manifold) is designed to function as supplemental agent application for the area under
the back-shelf. It replaces the agent lost because of the shelf. It provides an area of protection 15” deep
and 42” wide when used over a range.
The back-shelf or salamander can extend 1” beyond the centerline of the appliance with the manifold
nozzle tips located 14” to 19” above the appliance. The first nozzle must be placed ½” outside the edge
of the hazard and on the centerline of the hazard area covered by the shelf.
