I am looking at a Demo model Wolf 36" Range DF366 from a dealer. The range has never been used but is a floor demo model and is about 4 years old. Does anyone know of any changes that Wolf has made on their ranges in the last 4-5 years I should be concerned about. The only thing the seller indicated is that it is NG only and cannot be converted to LP. I think Wolf changed their racks in the oven to have one ball bearing rack, I�m not sure when that change was made. The seller is a Wolf Dealer, should the 5 year warranty start once they sell it as a demo? Is there a bad year to buy Wolf ranges when they were having problems? I know some of the high end ranges have problems, so I want to understand what I am getting myself into.

Also I need to have a hood that I can vent out the back and down under the house. I am considering a remote blower Wolf. FI you want a horizonal discharge is that a different hood or an added kit to the vertical discharge.

Thanks

Greg
