After some long research and not wanting to be late with my initial pellet purchase I have decided to buy some 'New England Wood Pellets".
http://www.pelletheat.com/products-a...-products.html
I have heard nothing but positive feedback about these pellets, from Forums and stove dealers.
Also called Napolean customer service and they basically, the stove can burn hardwood or softwod if it meets the following P.F.I. pellet stadards for my stove as follows:
* Size 1/4" to 5/16" diameter, 1/2" - 1 1/2" long maximum
* Ash Content 1% maximum (Premium grade) / 3% maximum (Standard grade)
* Moisture Content 8% maximum
* Heat Content Approximately 8200 BTU per pound minimum
That said N.E. Wood Pellets fits the bill !
Thanks,
