Show photos of the hood from the outside including at least one of the hood and the cooking appliance below it.

Have you checked for a plate with the model number, serial number, voltage, etc?

Did you confirm that there is not enough flexibility in the fan housings to accommodate sliding the baffle assemblies under them? Maybe contact is intended. Or, maybe the fan housings have "drooped" in some manner from their intended mounting. Experiment by pushing up on them.

Thank you guys for the responses. Here's a photo of it from outside, as well as the plate with the model number, etc.

As for the flexibility, everything is very rigid. The fan is attached to a plate that bolts to the top of the unit and the baffles are all boxed out, so they also have no flexibility. I attached another photo with the baffle slid right up against the fan body so you can see how much interference there is.

Tis a mystery. Are the baffles themselves less "thick" than the baffle assembly ends such that they would go under the fan housings when properly aligned with them?

is there a grease trough missing that should be positioning these differently?

The manuals are linked here. The Installation Instructions describe how to attach the blower to the hood. Given that the hood was previously installed and the filters fit OK, I will guess that the blower -- model VIV1200; see page 8 for instructions on how to attach it to the hood -- was not reinstalled correctly and hangs too low, blocking the filters. I would remove the blower and reinstall it, carefully following the instructions on page 8. Worth a try!

Thanks for the info @wdccruise. I'll look at it again, but the re-install of the blower was pretty straightforward. As you say, worth another look though.

My gut says I'm missing a piece that would hold the baffles on the bottom, but I dont' see where it would attach... I may just have to get my local sheet metal guys to bend something up for me.

I can imagine that if Steps 3 and 4 of the blower Installation Instructions (page 8) weren't followed correctly, the blower could hang too low.

3. Engage tab on ventilator with slot in rough-in plate AND engage slot in ventilator with barrel nut on threaded stud.

4. Push ventilator towards the back of hood to fully engage.

Added:

I would also make sure that the Top of Hood is properly installed; the Rough-in Plate is flat (i.e., not bent) and the Rough-in Plate properly installed (i.e., as high as possible to the Top of Hood). Any mistake could also cause the blower to hang too low.

@wdccruise Thanks again. I HOPE that is the issue and I just need to adjust. My HVAC guys installed the fan unit when I wasn't there, so it is definitely worth a second look.

You are missing the grease trough that the filters sit in - its a long track that hooks on to the lip. We have a similar hood and once you have that piece the filters will clear the blower

@dcarendt Thank you so much! Any chance you could send me a pic of yours, maybe with one or two of the baffles removed so I can see the relationship? Additionally if it wouldn't be too much trouble, would it be possible to send a pic of the grease trough itself, away from the rest of the unit? Hopefully I can have one of the local sheet metal shops bend me something up. That part must have gotten tossed somewhere along the line in the remodel...

If you're ever in the Bend, OR area I'd happily buy you lunch and a beer or three! Thanks again!

dcarendt: "You are missing the grease trough that the filters sit in - its a long track that hooks on to the lip"

Are you saying that the grease trough attaches here?

here you go. the trough has a higher lip on the back end that hooks under and catches under

@dcarendt . Thank you so much for your help. Not only did it let me know what I was missing, I actually found the part leaning against the corner of the garage behind some materials! Thanks again for chiming in. Don't forget if you end up in Bend, Or to look my up for your free lunch.

• Bubba: "Well, we finally finished installing that hood!"
• Hubba: "Yeah, looks great!"
• Bubba: "What about this piece of metal?"
• Hubba: "Dunno. Well, you know there are always left over parts in a job like this."
• Bubba: "Yeah, I'll just stick it in the corner. They'll probably never miss it."
• Hubba: "So Bubba, where are you going now that we've finished?"
• Bubba: "Far away from here!"
