(69 <br /> Icm)in width.Follow down the Range Length column in the Nozzle Positioning Chart until <br /> vou come to 20 in.(51 cm). Continue down this column until the correct width appears in <br /> the width column.When the width of 27 in.(69 cm)is arrived at,read across to the radius <br /> column to determine the size of radius allowed,for positioning of the nozzle,from the hazard <br /> area centerline.In this example,the correct radius is 3 in. (8 cm).The nozzle can be aimed <br /> straight down anywhere within a 3 in. (S cm)radius of the hazard area centerline. <br /> _. <br /> __ _ _ _ -- _ __ . _ _ <br /> Noxxle must be located�heigbi�wise�anywhere witbin the shaded area, <br /> '!_ _and centered above the cooking su�ce.
