I've had a Santa Fe now for 10 years. Its a good little stove. I've had to replace both the combustion fan and blower fan in last year due to the loud noises they were making. But that is about it for real repairs. I'm using Pro Pellets and I've noticed that I need to have the feed rate all the way down to get it to burn correctly. If I open it up more it will just fill faster and the fly ash situation can't keep up. While I don't think this is a problem really, I guess it depends on the pellet that I use probably. I keep the stove very clean as I'm good at that. Does any other quad user keep their feed rate all the way down ?? Curious ..
