So i got the Centrifugal Blower 115 Volts Fasco # 50747-D401 delivered today. It was a perfect match with my Federal Airtight insert. It made a big difference in spreading the heat around the room and the entire floor. I just need to ground this thing, i didn't have the proper wiring to do so.... I attached a photo as well.
Looks good. I wonder. Is it possible that you can reverse the mounting so that the wires are toward the wall (chmney) rather that toward the room? That means that the squirrel cage and motor are oriented upwards, above the exhaust, rather than down. Seems like that would look better.
If not, at least you have a solution and a working part that fits the stove. Glad to be of help. I believe you can attach the green ground wire from the 3-wire cord to any part of the cage or the stove. That should ground it out.
