PLENUM PROTECTION
NOTE: An Amerex KP & ZD Kitchen Fire Suppression System have the same listed
criteria for the protection of the Duct and Plenum.
PLENUM PROTECTION LIMITATIONS –
SINGLE FLOW POINT NOZZLE (P/N 11982)
The Amerex Appliance, Plenum Nozzle (P/N 11982) is capable of protecting plenums up to 10 feet (3.048m)
long with either a single inclined filter bank or a “V” bank filter arrangement. The filter height cannot exceed
24 inches (60.96 cm). Each plenum nozzle uses one flow point. The nozzle must be positioned 4 inches
(10.16) maximum from the end wall of the hood, aimed horizontally and positioned down 1/3 the vertical filter
height from the top of the filter. The width of a “V” bank filter arrangement is limited to a maximum of 48” (122
cm).
PLENUM PROTECTION – MULTIPLE NOZZLES
Plenums exceeding 10 feet (3.048 m) in length may be
protected by using multiple plenum nozzles. Each nozzle must
be protecting an area of no more than 10 feet in length.
Nozzles may be positioned facing each other or facing the
same direction as long as the entire plenum area is being
covered. Nozzles may not face in opposite directions from a
common tee.
