Mr. Heater F299201 Vent-Free Blower Accessory Kit (2016-present), Multi

Fit perfectly and easy to install. Works great.

More getting done! Blower made a difference but feel it could be bigger and pushing more air. I do like this setup for my 1000’ square foot shop. Very happy!

I'm a completionist. If I open a device and find an unused bunch of solder pads on the PCB, I dream of soldering something to it and getting an extra feature, so to find out Mr Heater took all of the fans out of their appliances and that I can add it back to mine, I had to do it. I saw people saying it gets its air from the back, where there is no room, but mine is on legs so that's not true. I saw a video of someone unscrewing a cover plate to expose the port this fan screw into, but that's also not true, for my model, since that port was covered with a tack welded steel plate, and I had to knock that plate out with a hammer to install the fan. The fan came with a temperature sensor to screw into a steel plate in the fan, and that was very difficult, because to line up the sensor with its hole, and get its screws into its screw holes without bending any of the thin sheet metal took a lot of patience. You will never be able to do any of that without taking the whole front off the unit, and then putting the front back on was a pain in the ass, since the metal kept deforming, so tabs weren't lining up. I finally got it all back together and, unlike what so many people said, the Auto feature works great. So what is this fan? Does it cool the inside of the unit or does it push air around the room? It does suck air in the unit, but it has a steel duct to lead that air straight out the front, so almost none of that cold air ends up in the unit. After 30 minutes on high, my unit was too hit to pick up from the sides, and hot enough that I would worry about it melting something that touches it. I kept checking the screw-attached safety label, which is plastic, to see if that had melted; it hadn't. Since the unit isn't staying cool, does the fan move air around the room? It does dump out about as much air as a computer's power supply, right into the path of rising heat at the top of the unit, but it does that ONLY on the left side (while facing the front of the unit - the side it's installed on) so if this is helping mix the super hot air with some cool air, it isn't doing it on both sides, which is stupid. Why doesn't that duct connect toa widener on the inside that goes across the whole unit? In summary, it's a rough install, it does work as advertised and it's nice that all of the screws it uses match the other ones the case uses. If the unit was meant to have it, I think everyone should have it, but I can't tell you it does a good job of cooling the unit. It surely adding some cool air to the hot air the unit makes, but if it adds enough to matter, or if it mixes that air well is still a question. It's too bad Mr. Buddy engineers don't come on here and explain the reason the fan ports air from back to front, skipping the inside, and why it's only spraying air out one side.

Works great!!!

Perfect fit for my 30k BTU Mr heater. Installed in minutes. Seems to function as it’s supposed to. Very quiet as well.

Products performed as advertised.

I had ordered this for a Mr.Heater I’d ordered for my parents it was super easy to install works great highly recommend it .

My gas heater is mounted to the wall so in order to make this work I had to use some plastic shims (as shown in picture) to bring the heater away from the wall about 3 inches to allow the air to flow through the fan otherwise it wouldn’t of worked in pushing air. It works a little bit, I mean it’s a small fan it can only do so much but it does help move heat around a bit. I don’t like how it takes along time for the fan to turn on and off when it’s on automatic mode because it’s ran of a thermostat. I wish there was a way to improve that feature . Overall not a bad fan it’s just more expensive than it should be in my opinion
