OVERLAPPING NOZZLE COVERAGE (Continued)
Overlapping Appliance Nozzle and Hazard Zone Locations
– Group Protection
1. For each group of protected appliances under a common
hood(s), the overlapping nozzles must be located from
right to left so that each end nozzle is located a maximum
of 6 in. (152 mm) inside the outside edge of the cooking
hazard of each end appliance, and the inside overlapping
nozzles must be located between the two end nozzles at a
maximum spacing of 12 in. (304 mm). See Figures 4-108
and 4-109.

2. When obstructions are located adjacent to appliance(s)
protected by overlapping nozzles, the overlapping appliance
nozzle spacing must start with the appliance(s) adjacent to
the obstruction. See Figure 4-110.

3. When an appliance requires dedicated protection with a
protected area intended for overlapping appliance nozzle
protection, the group protection option will be required for
appliances on either side of the appliances using dedicated
protection. Group protection using overlapping appliance
nozzles must begin with the protected appliance(s) adjacent
to the dedicated appliance protected. An overlapping appli-
ance nozzle(s) must be positioned within 6 in. (152 mm) of
the edge(s) of the appliance hazard surface area(s) adja-
cent to the dedicated nozzle protection. See Figure 4-111.
