I'm having trouble with this crappy stove. It soots up, shuts down every few hours and isn't putting out enough heat. I have done everything, cleaned everything. I think the stove is just crap. I keep reading about factory settings and modes like 1-4-1, etc. Where are you finding these settings? How do I find them and set them? I have looked in the manual and on the site and found nothing. Everyone talks about the settings, but no one says how to do it. I guess I'm way out of the loop. Can anyone point me in the right direction? Thanks
