temperature.
3. The agent reacts with hot grease forming a soap-like
layer (saponification) that helps prevent the escape of
combustible vapors, thus preventing re-ignition.
The shutdown of all sources of fuel and electric power that
produce heat to all equipment protected by the system is
required upon system actuation. It is recommended that
make up or supply air fans, integral to the exhaust hood(s)
being protected, should be shut down upon system actua-
tion. Exhaust fan(s) in the ventilation system should remain
on during system discharge as they assist the dispersion of
chemical through the ventilating system.The system is UL
Listed with or without exhaust fan shutdown.
The KITCHEN KNIGHT II and the KITCHEN KNIGHT
Restaurant Fire Suppression System are compatible as long
as separate installation guidelines are followed per each
system design manual. Exception:The actuation limitations
for the KITCHEN KNIGHT II system may be utilized for the
KITCHEN KNIGHT system.Also, control heads, prior to
Model No. 3, may be utilized on KITCHEN KNIGHT II
sytems, provided that the limitations used with those control
heads are followed.

The Model IL Nozzle, Part No.551026, is a one (1) flow
nozzle.A single IL nozzle is capable of protecting square or
rectangular ducts with a maximum perimeter of 50 in. -
(127 cm), with the diagonal being a maximum of 18 3/4 in.
(47.6 cm). It can alsoprotect a round duct with a maximum
diameter of 16 in. (40.6 cm).
The Model 2D duct nozzle, Part No.551038, is a two (2)
flow nozzle.A single 2D nozzle is capable of protecting
square or rectangular ducts with a maximum perimeter of
100 in. (254 cm), with the diagonal being a maximum of
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
directly into the duct opening.
