NOTE: Overlapping nozzle spacing and height requirements are based on the appliances protected
for each individual zone. Nozzles must always be located at the start and end of each zone, no
more than 12” from the end of the hazard zone (edge of 1st/last cooking appliance surface). Refer
to “Overlapping Appliance Protection” on page 19. Zones cannot overlap.
NOTE: All hazard surfaces in a zone must be within 35”-50” of the nozzles in that zone.
Group Protection Example 1 – Appliance line separated by unprotected space.
End nozzles must be located 12” or less (horizontally) from the end of the hazard zone. Standard
overlapping nozzles must be spaced no further than the maximum allowed interval 36” on center. Refer to
“Coverage Exceptions” on page 21 for more details on coverage exceptions.
