There are a few explanations as to why you maybe smelling a burning smell when you turn on your furnace for the first time of the season.

On every furnace there is a protective coating on it which protects your family from gasses like carbon monoxide which is naturally produced when the heating process begins. If you start smelling burning when you first turn on the furnace this could be because of the coating and this smell should go away within a few minutes.
