A:Answer Hello,
Thank you for your interest in the GE Freestanding Double Oven
Gas Range model JGB850SEFSS.
Yes, Using LP (liquid propane) gas instead of natural will lower the
BTU* output, thus slowing the cooking process.
The main reason is simply when converting to LP gas from Natural
gas you use a reduced size orifice. LP is a heavier fuel to combust, and
the reduced orifices are used in order to prevent large flames and soot issues.
As a result, BTU rating does decrease noticeably on the larger burners but is
not as noticeable on the smaller burners.
POWER / RATINGS
Bake/Broiler BTU Rating - LP (000's BTU's) 10.0 / 10.0 - Upper; 13.5 / 0.0 - Lower
