Maximum nominal excess fuel at 0.25 osi/4.3"w.c./1.1 mbar = 180%: at 1.0 osi/1.7"w..c./4.3 mbar = 200% Flame Lengths listed on this page are for open still air. Actual lengths when fired in a burner body will vary. The reduced port models of the 4020-6 and -7 pilots provide stronger, higher capacity flames than the standard version with the same exit size.
