No problem!
Now if I could just remember how to convert PSI to " WC without googling.
Just remember - 27.7"WC = 1psi.
Also, just another tidbit of info that alot of other folks probably are not aware of - the pressure in a propane tank varies GREATLY due to ambient temps - at 0F, it's only ~25psig and at 100F it's up to ~180psig!
