Recently purchased a lake/second home that came with an Ashley Automatic 25HF Looks like this That is just a web image that I found. My stove is in great physical condition. I'm not worried about efficiency because I will only visit this house 4-6 days per month over the winter. I fired it up last time I was there and it heated the house great, however I don't know how to control the intake. Not sure what the dial you see in the picture is for and how that relates to the intake. Anyone know how to operate this stove? Is is possible to get an overnight burn in one of these? Any other useful info? Thanks!
