The Model IL Nozzle, Part No. 551026, Is a one (1) flow

■ 37 3/8 In. (94.9 cm). It can also protect a round duct with a
maximum diameter of 31 7/8 in. (81 cm).
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

duct(s) of protected ventilation hoods. Detectors shall be
located in the plenum area of the ventilation hood.

Exhaust Duct(s).
Each exhaust duct must have at least one (1) detector _
installed in the duct entrance, located in the air stream of the
cooking vapors at a maximum of 12 feet (3.7 m) into the ,

If an electrostatic precipitator Is located at or near the base of
the exhaust duct, it is necessary to locate a detector below the
precipitator, at the base of the duct, and also locate one in the
duct, just above the precipitator. See Figure 3 -23a.
