well i finally installed my nps40 napoleon today,nice day 55 degrees. so far i played around with settings seems to be a stove that changes nicely with the settings.ran with windows open for a hour or so and smell was very little if any. trying energex pellets,which i did vacuum before putting and had about two cup fulls of fines per bag. will be interesting to try when colder.this forum has helped alot with piping suggestions,pellet brands etc. thanks everyone
