As a general matter the Coal-trol works with the 140. There are caveats, though:
- Alaska has been telling their customers since we first started selling Coal-trol that they void the warranty on any stove that gets the Coal-trol installed on it. I believe there is some question as to what they can legally deny warranty coverage on (e.g. car companies and dealers can't void the warranty on everything when you install an aftermarket stereo), but I'm not a lawyer and I don't know for sure one way or the other. Regardless, the fact remains that Alaska is likely going to give you a lot of resistance if you need to get a motor replaced or some other warranty repair/replacement.
- We only support the use of Coal-trol on this appliance for use with coal. We had a report of one person looking into burning pellets in their 140 with the Coal-trol. We do not know if the 140 is certified for burning this fuel and do not want to encourage using the stove in a way that is not tested and cleared by the manufacturer.
- If you intend to install on a 140, please contact us with the current rating of the blower fan. We've run a 140 for a couple of hours without problems due to current draw, but we'd want to be sure the ratings of the blower and our fan circuit are sympatico. We also want to make sure you understand the warranty issue clearly, to avoid hard feelings down the road.
