Incidentally, I didn't ask you....I made a statement. 11"wc for LP is not
ideal delivery pressure, 10" wc however is. 8.5" wc is too low and will
give an excessively yellow flame and a "dirty" burn.

3.5 inches WC is normal manifold pressure for natural gas. 11 inches
wc is normal manifold pressure for LP, although some LP burners go as
low as 8.5 Inches WC. Don't ask me, check with rour gas supplier. Or
a service tech with a manometer who knows how to check it.
