If you are running a Masterbilt XL with two burners, you can just use one burner or instead of turning dial counterclockwise, you can turn it slowly clockwise for a lower flame than the “LOW” setting.
@Jonathon You need a natural gas propane grill so you can just let it run 24/7/365 and never have to worry about running out of fuel or coming home to a grill that isn’t ready to sear a steak!
