When converting most common fueled appliances, such as Cooktops, ovens,

lowers the BTU's.

Why would that be? LP gas has approximately twice the BTU content by volume as
natural gas. Even if if the orifice was reduced by half, the heat content would
be the same, not less.

For example, re-jet a Viking gas cooktop for LP, and each burner's BTU
rating drops by 500, as per spec sheet he

on page 2.

I don't have the spec handy, but my gas fireplace rating is lower with
LP than NG as well.
