Griddle Protection 2120 (2-Flow) Nozzle – Low Proximity
Application
Option 2b – Nozzle Perimeter Located (Continued)
10 in. to 20 in. (254 mm to 508 mm) above the cooking surface.
The low proximity application uses the 2120 nozzle.
The nozzle is stamped with 2120 indicating this is a two-ow
nozzle and must be counted as two ow numbers.
One 2120 nozzle will protect a maximum cooking area of 1440
in.
2
(92903 mm
2
) with a maximum dimension of 48 in. (1219 mm).
When using this nozzle for griddle protection, the nozzle must
be positioned along the perimeter to 2 in. (50 mm) inside perim-
eter, and aimed at the center of the cooking surface. See Figure
4-47 and 4-48.
