*Also available with 1/8" N.P.T.
Based on 3.5" w.c. for City gases and 11" w.c. gas pressure for LP
gases.
"City" gas is any gas with specific gravity of less
than 1.0; LP gas is any gas with a specific
gravity of more than 1.0 (Propane or Butane).
Flat flame jets have 1/8" N.P.T. so they are gas tight without
the hex bottoming. This allows turning of jets for exact
positioning of flat flame.
