When two (2) 2D duct nozzles are used to protect a single
duct, the cross sectional area of the duct must be divided
into two equal symmetrical areas. The nozzle must then be
installed on the centerline of the area it protects and aimed
directly into the duct opening.
The nozzle(s) must be installed on the centerline of the duct,
with the tip located 0 to 6 in. into the opening, and aimed
directly into the duct opening. See Figure 3-1.
