I have a 1537 and I used the adapter that screws into the back of the stove as a template and drilled 2 holes in the ash door and mounted the fan right to the door. Not the way I wanted to, but it works. I really wanted to make an adapter but after I looked at it I thought it would be ok. I also added a 3 speed fan control and mounted that to the side so I could control the amount of air being pushed in. It worked well this morning, I turned it up high, let it burn for 10 minutes or so, added a load, let it burn for another 10, shook it, rodded under the grate, let it burn another 10, topped it off and let it burn another 10. I shut off the fan, closed the draft on the side about 3/4. We'll see how it is when I get home. I've been a little conserative on putting the air to it until I really figure out what I'm doing. This morning I let it rip, brought up the temp in the house 6 or 7 degrees in an hour. The plan for tonight will be turn fan on high, load'er up see what happens and shut it down for the night. Hopefully it will all work out.
