It burns the coal much more completely and you'll be much happier with the unit. I don't know what I was thinking, not to recommend that earlier. I have two metal fan blade wheels I'm not using anymore on the shelf. After converting, you'll never go back the way it was. It works so much better!!!
Matthaus wrote:Yes, you can search ebay for a fan and save yourself some money, if I remember correctly the flue outlet is right under the stoker (unless you have a top vent), so you will need a low profile fan or fashion a right angle adapter.
I attached a pic of a stove with the external fan mounted.

Just replace the fan with an external fan unit, 30 to 60 SCFM that will fit over the inlet. Your stove will operate better and you won't have any more issues with burned out fans.
Matthaus wrote:How about a picture? Sounds like you already have a separate combustion fan, if so just call Alaska or the dealer and order a metal fan. I am thinking though that if your stove is direct vent and you are melting plastic fans when the power goes off then you might want to hook the direct vent to some kind of an UPS to keep it running long enough to vent the hot gas till it goes out.
Bottom line is we can probably help you if we have more information.
