<br /> Example:A four burner range has a hazard size of 20 in.(51 cm)in length and 27 in.(69
<br /> cm)in width.Follow down the Range Length column in the Nozzle Positioning Chart until
<br /> you 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.(8 cm)radius of the hazard area centerline.
