A:Answer Hi Lisa,
The LP BTU ratings for the cook top burners on the new NY58J9850 Dual Fuel Flex Duo Slide-In Range are as follows: Right front - 16.5 LP; Right rear - 4K LP; Left front - 11.5K LP; Left rear - 7.5K LP; Center oval - 7.5K LP. The LP conversion kit comes packaged with the Range, and should be installed by a qualified gas installer.
Samsung Slide-in Ranges do come with a filler kit to fill the gap between the back of the Range and the wall, but there's currently no back splash accessory available. I would suggest working with a kitchen designer for assistance determining possible solutions.
Thank you!
Ms. Samsung
