Question: do i have to put a baffle around it to keep attic insulation away from it?
Document: I got this to replace one where the motor burned out, I got the exact same model so I did not have to get into to the attic and rip the case out of the framing, I just put the guts of this one into the old case that was mounted. The old one was about 12 years old and got a lot of use.
Like the SD 480 Garden Cart. I had to purchase some of the parts just to put it together. Then there was the lousy helicopter model that I received and threw away. Not seeing the item has its disadvantages. But I have also saved lots of money by purchasing the items on line. Quality Control is missing in some companies.
This thing really moves some air around with the vent/fan. The only complaint is that it is a little louder than what we are used to, but it does the job.
Bought this to replace my existing fan that went out. Since it was the same one, all I needed to do was swap the inside parts and the cover. Did it all in the bathroom, no time in the attic.
This heater is going on three years for us and it's going strong. We don't have an adjustable thermostat for the heater though and it can really put out some heat, but all we do is turn it off for a bit and leave the vent going. I've been very impressed by this combo
Purchased this unit and replaced an older model. This unit runs much quieter, seems to work well so far. Be prepared to work in the attic to install these units, they cannot be installed from below.
In my case, I just replaced it all except the housing of course, since I don't want to crawl up in the attic and deal with that mess. I'll order the remaining two units, do the replacements, and wait for another 30 years before I need to change them out again.
Quality brand name, that's why I purchase it to replace our noisy one. However, this unit vibrates and is very noisy. The metal is so weak that it reverberates when the fan is turned on. I'm going to have to put some screws in the unit to stop the vibrating. I wouldn't purchase it again
Rebuilding a send house and discovered these on sale here . Great Price . Have not totally installed the inner parts as of yet but the cans are up & wired . After I get the Sheetrock in and test them I will do an update. I complaints about the exhaust , but I just installeda flex  hose up in to the attic where the odor will be  in the ventilation draft part of the attic.
Very easy to use the "plug in parts" (the fan, light and heater) to replace my existing system. My heater went out in the my old unit and when I bought this new unit i thought I would have to go into the attic and replace the whole unit. Not the case at all. Broan made all the parts interchangeable and all I had to do was unplug the old heater and replace it with the new heater.
Answer: yes
