I searched the internet and found the conversion kit to LP gas at Appliancepartspros.com. their price was the least expensive. The instructions were excellent in describing the removal of the nat. gas orifice and replacement with LP orifice.
The part was delivered 3 days after ordered by Fed Ex., a speedy delivery!
I finished installing my clothes dryer and it works fine. I have some experience with such equipment but recommend professional installation for reasons of safety!
Thank you, R.P.
