Description
The Auto-Draft can be installed on any wood or coal burning stove pipe 5" to 8" in diameter. It is designed to solve draft problems without increasing the height or diameter of the chimney. With the Auto-Draft your hard starting stove draws immediately. No smoky back up--even with moist or hard to ignite types of wood. Once the fire is burning, adjust the variable speed control knob on the electrical box to achieve the maximum efficiency of your stove. The Auto-Draft provides for total utilization of your wood, leaving only a fine ash residue in most cases.

works well to keep smoke from coming out of the fire box when you open the stove door to put in wood. great for getting the fire going. I turn it down or off once logs are burning ( it does make the wood burn hot and will burn it faster than normal if you keep it running). Very pleased.

Helps my coal forge to get the smoke up that chimney. Seems to be working nicely.

I've had a wood stove in my basement for almost ten years. My stack runs straight up 5-6 feet to insulated chimney pipe, out horizontal another 6, then up 20. Getting a natural draft going is usually easy, but there are rare occasions where negative pressure in the basement from atmospheric conditions or the power vent on the gas furnace causes us some serious trouble keeping smoke from billowing out of the stove. Before lighting I could even feel a powerful, cold down draft from outside. After installing this fan, any issues with the draft in the same conditions have been non-existent. It also keeps the excessive smoke smell from filling up the basement that even starting up a small amount of kindling would have before. Don't expect it to pull up all of the fumes when the door is open. You will still know by nose that a fire is going; it will just be a light scent like a fireplace. I don't normally run it on full speed when lighting and turn it off after the stove warms up. Installation could have been easier, though. Do what other have said and toss the instructions. I pulled the entire pipe from stove to insulated chimney pipe, to make it easier to work with and to inspect for creosote buildup. I carefully measured and cut my pipe with a dremel and jigsaw, making sure the top lip would slip into the pipe and the blades wouldn't catch. Then I marked and drilled holes and used the splined studs that came in the hardware kit(the ones the instructions don't even mention). The last nut by the motor was a pain because they don't give you enough clearance for even a 1/4" ratchet. Just make sure you install yours above any heat exchanger or cleanout your stack might have. I put mine above the Magic Heat we had for years just to make sure it didn't leak. Also, invest in a tube of 600° F sealant for $4-8.The included fiberglass gasket tape is not going to seal around all the gaps that even a perfect cut would have. I caulked around ever joint from the fan to the chimney. Pulling that off to clean is better that breathing carbon monoxide. When I saw it puffing some smoke, the blower housing that should have had factory powder coat sealing it got small beads around it. The build quality one this unit is decent, but the design could use improvements. I already mentioned the blocked screw hole that made things harder for me. The electrical box cover also vibrates so I gave it a tiny bead just by the blower to keep it still without blocking air cooling for the control. That at least was easy to solve. The control could have been made easy turn for a more awkward installation I sure some people have. And I had to add a cord to it. Every other fan or blower I see on the market has a simple a plug. They could have included one with clear warnings not to let it anywhere near the hot surfaces. Mine is well away from anything. There is also a large(about 2" sq). hole by the blower shaft open to the insides of the pipe. This does draw in air to keep heat from the motor but I'm worried starting a fire after power goes out might have that hole belching smoke for a long time before a draft gets going. It doesn't seem to let out any flue gasses when the coals are dying down, though. I'll have to cut out some sheet metal or machine a block to make it smaller and slip that over the shaft when I have no power to keep smoke in. It just would be nice if something was included to block that hole in an emergency. All in all if you have draft issues with a freshly cleaned chimney, then you need something like this. It also lets you load your stove without smoke puffing out of the door. I've had mine for only a short time and don't know the longevity of it, but I'm happy with it for now.

I am a career tradesman with the proficiency to build, fix, modify and install just about anything and this product has compelled me to take the time to write the FIRST negative review I have EVER written in my life about ANYTHING. Read that again.... I cannot comprehend how a company can manufacture, promote, sell and pretend to stand behind something this utterly flawed and useless. 1.) The fan housing is JUNK because: - it is spot welded and smoke comes out of the seams * I sealed the inside with wood stove cement to fix - The paint is garbage and melts/burns off during the first fire *I'm a resilient redneck who doesn't complain but the house filled with noxious fumes - The opening where the fan motor shaft enters the housing is literally a 2" hole straight into the stove pipe....smoke pours out. Who designed this? Are you kidding me? * I machined a custom metal plate that sealed the hole to within 1/32 inch and it was almost a solution - The flanges that screw to the stove pipe leave substantial gaps at the corners. I sealed with a large amount of high temp goop, but will the average buyer know how to do that? -The fan control knob faces the Wong way and is hard to reach. * I modified the mounting hardware to fix this but JFC! 2.). The speed control switch is JUNK. Died after 2 days of use. Replaced with fan control switch from hardware store. 3.). Fan blades inside stove pipe obstruct air flow too much when not running. It has to run constantly or it restricts up-draft more than whatever issue you're trying to fix. I am throwing this in the garbage. There are no redeeming qualities even worth mentioning. JUST DONT BUY IT.

We have had so many smokey room problems over the years with our woodstove and this has in a way solved all of it. I personally think that all woodstoves should be required to have a draft enducer built in in some way. I did alot of pre-reading so the install went realativley smoothly. I bought a new piece of 6 inch piece from Lowes, cut it to size and installed the fan on the clean pipe (no mess) and then replaced a section with the fully assembled piece. Its mounted horizontially. A few changes I made. I did the potentiometer adjustment to make the slower fan speed much slower. I havent had the need to use the slowest speed much though, so its was probably not nessessary. I then removed the switch from the ridiculously ugly housing its installed in (they could have done so much better) and relocated it into a single din housing that I mounted on the wall behind the wood stove. Everything sealed with black high temp RTV. Install went well and came out clean. The PROS, if there is even one or two coals left, I can get a fire going again by putting in a few new logs, turning on the fan and leaving the door open an inch or two, the draft coming in is enough to get new logs burning. Anytime I want to stoke a slow fire, just do the same as described for a minute or two. Anytime we need to add new logs on a low burning fire, we will turn on the fan, and then put logs in. No smoke enters the room at all, which is a huge change to what we experienced before we got the draft enducer(fan). Cons, its fugly. Looks like it was enginered in the 1920s. Leaks like a strainer until every edge is sealed. As others have said, the RTV will let off some seriously bad fumes when first fired. If you stay in the room your eyes will be stinging all day. All in all I am happy with this thing and my wife enjoys the benefits enough to give me a pass on its looks.
