This high proximity application uses the 290 nozzle. <br /> Hlgh Pmxlmlty Application;35 in.t0 40 in. (689 tO 1016 MM) The nozzle is stamped with 290 indicating this is a 2-flow nozzle <br /> above the c00king OUft0e. and must be counted as two flow numbers. <br /> This high proximity application uses the 1N nozzle.
