I would like to know the difference between an outdoor ceiling fan listed as damp compared to wet.. I have an open outsid porch/deck with roof just ahe fron and sides are open not screen or glass. The top is covered and one side is butted up to back of house, leaving front ans sides open, spindles are on front and sides as are the steps . Can I use your indorr/oputdoor damp rating fan on this typr or porch or do I have to use one wet rated? Please help no one at Lowe's or home depot know and neither do my friends Thanks Frank
