Your cart is empty.Tjernlund In-Line Draft Inducers assure positive draft when restricted boilers and furnaces, poor chimneys or negative pressures in buildings prevent proper exhaust of combustion gases. The venturi action starts air moving up the stack instantly & keeps it moving smoothly. These units are quick and easy to install and completely automatic in operation. In-Line Draft Inducers are built for long-lasting, trouble-free service and available in sizes and capacities to meet virtually all heating system requirements. The Vari-Draft control permits adjustment to individual job requirements.

I use this in an wood burning stove for a detached shop. The smoke would back blow into the shop to the point I couldn't see. Spent about an hour putting this on the 4" pipe of the stove. Now the smoke is pulled through the fan and goes smoothly out of the chimney.

My gas water heater is a crappy Rheem low NOx with motorized damper valve unit that only works well when there is a strong flue draft or when the water heater has been running and the flue is warm. If it were not for a local gas company rebate i would not have gotten this unreliable low NOx version. However, this draft inducer fan makes the gas heater run more reliably and the heater does not fault out and throw error codes as much, and it is about an order of magnitude more reliable than before. This fan did the trick. I used a generous amount of high temp heat duct aluminum foil tape to seal the pipe around and after the fan to make sure exhaust gases are not coming into the house. The fan makes some noise and a little bit of vibration, but it is acceptable and inline with my expectations. I put in a breakbean IR sensor on the motorized damper valve with a relay to only turn on the draft inducer fan when the damper is open. Its been working well for a year now so far.

I have a through the wall pipe for my wood stoveWas getting smoke during startup and loadingThe fire was also not burning like it should "lazy fire"-Solved the smoke problem about 95 percent which is great!-Fires are really easy to light and they continue to flame when the doors shut-Gets the wood stove up to operating temperature within minutes (250 degrees)-Makes starting and maintaining heat much easier for my older dad--less work.If you are having any wood stove problems get one of these--rated at 575 degrees.Used an angle grinder to cut the hole (came with a sticker that adheres to the pipe)I used self tapping screws instead of the ones included.Used Red high heat silicone to seal it (under the side flanges and then on the top and bottom on the outside.Insert the small flange on top--into the stove pipe, then put in the bottom, once flush push the unit up and hold (may need some help) while you get your first screw into place.Bought a 3 foot plug with open wires and wire nutted the like colored wires together (fan and plug)--plug in, the fan is on--unplug the fan, is off--easy.Mounted the fan vertically after the damper and before the elbow (includes examples for locations and wiring differences).So far so good--been running without issue about a week.

The good: The draft inducer works great.We bought it to help with a smoke problem in our newly built coal fired forge.The inducer works great! We were a little skeptical about its ability to move enough air to be effective.It turns out to have plenty of volume.The installation was a little tricky but the wiring was a piece of cake. I wish it would come with all the hardware. Missing was a conduit clamp that you have to use to keep the incoming conduit from getting cut over time.The bad: Well, it really isn't all that bad. Just annoying.The problem is in the template. You have to be VERY careful when applying the template to the exhaust tube or it will not line up square which causes the mounting holes to be off just enough to be problematic.Once the hole is cut out in that case, it can't really be easily fixed properly.We wound up replacing one piece of the exhaust tube. Luckily I had made a copy of the template just in case.Overall thought this is a good product.Hopefully it will last for the long haul.

No more smoke filling my basement when I light up my woodstove cold. I used to be plagued by this problem. I'd open my woodstove door and I could feel that cold draft blowing down my chimney and unless I could get my stove hot fast my basement would fill with smoke and I'd have to open the windows. Not fun when you live in northern Canada and it's -30°C outside. This unit came with a cutout template for my stovepipe that helped with an easy installation. I am very please with this. Hands down one of the best investments I could have done for my wonderful woodstove life.

I just finished installing and testing for few hours, and I thought I will write down some notes about this draft inducer. My water heater is an "orphaned water heater" (type these words in Google and you will see some sites with good info). The first picture shows the rust on the top of my water heater due to backflow that happens in windy days :o(The inducer is well made, and comes as pictured. You will need to wire to plug in (I used an old desktop power cord). Inside the package, there is a template to be used (as a sticker) to make the appropriate cut in the duct and make the 4 holes to attach the inducer. It also contained 4 small bolts with metal clips (like those in cars called u-clips or panel clips) that go over the metal duct and has a thread to secure the screws.The owner manual says that can be installed from 3-6 inches duct. Yet, it will not fit well for 3 inches. Mine was 3 inches, and I used a drill bit to make the starting point, and a jigsaw with a metal blade to make the cuts. Once I made the cuts, I realized that there is no way for the lateral flaps to stay over the duct without bending it (this could cause a serious leak). Also, I should have waited to make the holes until the inducer is mounted on the vent duct. The holes did not align up in this attempt.So, I went to a closest hardware store, bought 4 inches duct and 2 pieces of adapters (3 to 4 inches). To make new cuts, got a Tjernlund specification pdf file on the web to get the size of the hole, make a simple template on paper, and restarted. Once it was mounted nicely, I made the holes, put the clips. And discover that 2 of the 4 bolts do not have clearance to use a nut or screwdriver to tighten. A bad design. I ended up using a needle plier to tighten.Although this product description in Amazon seems to indicate that you can control the speed with Vary-Draft control, there is nothing in the box to do it. So, it is a single speed as it comes (I think there is a more expensive package that includes few other things but it's 3-4 times more expensive). You plug in and it runs. To avoid this little motor to run all the time, I bought a "Century 7 Day Heavy Duty Digital Programmable Timer - Dual Outlet" here in Amazon. It allows you to program up to 8 on-offs a day. I have programmed 3 on-offs in weekdays and on weekends in slightly different times.The 2nd and 3rd pic shows both sides of the installation. The screws on the motor side are the ones without enough clearance for a screwdriver. The little zip ties and wire on the motor were used while I was installing the duct with the mounted draft inducer (since the weight tend to turn the duct). It allowed me to maintain the level for the motor as the user manual specifies while I was using some screws to secure the vent. The last pic is the timer that controls when the motor will be running. It is not a perfect solution, but simple enough for us that we have a regular schedule during the week with work and school. I have posted 4 pictures, so I hope that it will eventually show up.I hope that this helps a little.
