Maximum nominal excess fuel at 4.0 osi/6.9"w.c./17.2 mbar = 180%: at 16 osi/27.7"w.c./69 mbar = 200%. Flame Lengths listed on this page are for open still air. Actual lengths when fired in a burner body will vary. * With optional 4-20667-1 Valve/Orifice. The reduced port models of the 4030-6 and-7 pilots provide stronger, higher capacity flames than the standard version with the same exit size.
