Can I use this for house furnace (75,000 BTU) vent? This is the vent that goes all the way to the roof and out.

Not sure. I'm using it for a portable a/c vent into ceiling space. It is kinda thin and doesn't seem durable enough for a furnace vent

I don't think so. You can do that by using the roof vent with exhaust flapper.

This unit is designed to be vented outside. Hopefully you already have the duct connections to an exterior hooded vent. I've seen it vented to recirculate in an attic space, but that's definitely not recommended and isn't code-compliant in most jurisdictions. I have 2 of these in my own home and just put 3 in my parent's home. Love it!

I can't be sure. this motor covers a wide variety of applications, differing mainly by whose name is on the original vent kit. I have used this same motor to replace a variety of roof vent motors over the years, and they always fit. as long as the fan blade hub is bored for a 1/2" diameter shaft, and the outer diameter of the motor is the same, it will fit. the shaft is plenty long enough to allow placing the fan blades in the right position, and the mounting adapters supplied may or may not be needed. The only real change you may need to make is the bolts holding the motor together and serving as mounting bolts may have to be removed, and inserted form the opposite end of the motor...this is easily done, and it depends on how the motor needs to be mounted. It is pretty straight forward to replace the motor, but being in the attic, it is a predictably hot, miserable job! Be sure to turn off the power before starting this job!

I can't see why not. If you build a plywood frame around it or fit it to the window size as you would a window air conditioning unit, it should work. Keep in mind weather could possibly enter the vent if you keep it in all year.

Possibly, but I don't think the manufacturer intended it to be mounted that way. You'd need to contrive a way to keep it from falling out of the duct opening. As well, there usually is no electrical outlet nearby at the ceiling level. Better might be to get a different kind of unit, such as an In-line booster, with an air pressure switch to sense when the furnace fan comes on. Trickier to install, but more likely to do the job correctly.

The 60000 btu would work great. It is over sized but for the priceit is worth it. I have 750 sq ft garage with 12ft ceiling and it heats it up fast. Less strain on the unit.

I would think you would want at least the 75,000 BTU and may be better to move up to a 100,000 BTU unit.

YES. You need to vent anything with combustion. BUT this is the external module. The exhaust VENT is the narrow strip you see near the top front.

I would say no. This fan mounts in the wall. It fits through the thickness of the wall and vents directly to outside, using no duct. If you need to use a 4 inch vent pipe, I would buy a fan made for that application.

You should be able to.Instead of using the vent mount,just use the old mount.

Would not recommend trying even if it fits. This unit gives off some heat and needs clearance to vent itself. Also the pressure relief valve is on the top.

I have a Zephyr overhead vent and these would not work because they weren't long enough. I had to order directly from the mfg.

Felickz, I guess I misspoke about the size of the vent piping size, Which this fan does vent 6". I also recommended using the Broan 636 fan-jack but meant to use the Broan 634 fan-jack for roof installation or if venting sidewall use the Broan 843 which both have a back draft dampers. Hope this clears this up!!! Mark Innovative HVAC Systems, Inc.

No. It moves a lot of air and it would be restrictive to go to a 4 inch duct.

I would think it would need to be mounted to the supply duct so that it blows through the house with the rest of the hot air from the furnace.

Not exactly. The hole on the fan is 6". With that said I put a new 6" duct from the fan to the hole in the roof. The hole in the roof is a 4" hole. I just put a 6" to 4" transition and the fan runs fine. It is super quiet and gets plenty of flow.
