Rangehood install in sealed cabinet
 
Hi guys

I'm helping with a kitchen for a client. I'm not running the show, but doing odds and ends to help. The cabinet installer installed the hood cabinet as a solid unit with no removable panel to access the ductwork.

The cabinet guy is insisting that we should remove the motor from the $1000 Range hood to install it up to the pre-installed ducting. Problem is, the motor is a sealed unit with with the duct flange attached - 1 solid piece.

This would void warranty, not to mention that we wouldn't be able to tape the joint, and would only be guessing if the flange was properly seated on the flange.

Thoughts?

The 2nd picture got turned. It's looking up inside the cabinet from underneath.

no pics.

IMO, do not void warranty, there should be access to motor, ducts etc.

Modify the cabinet, or every time that unit has to be replaced It's going to be a problem.

The cabinet guy didn't know about the hood requirement?

Oh the kitchen company knew full well. They just chose to do it this way.
We figured out a way to prehook up the duct and slide the unit up into it. Just won't be able to tape the duct to flange...

Install may require taping to meet manufacturers requirements. I'd be careful about that due to stove fires catching hood grease on fire.

It does. However cab company was able to convince the homeowner that this is better than tearing out the cab. No GC on this kitchen install. My job was to gut and prep the kitchen, then bow out for everyone else to take over. I had no part of hiring the cab company or appliances. Yet here I am helping to install stuff.

Lazy... might want to mention to the customer to get a performance guarantee in writing from the guy for his "solution" before they continue forward...

I said exactly that. Get it in writing. But she won't. Yes the kitchen company was full of excuses. "We've seen it done this way a hundred times and they had no problems".

It might be a bit extreme, but can you bust through the ceiling above to get a bit of tape on the flange?

Bust through the ceiling and you have to bust through the cab... the guys doing the cabs could have easily modified that so it was done correctly...

Then they'd have no problem putting it in writing instead of making you deal with it...

Then after busting through the ceiling and the cab you have to fix them. Having a hole into an attic or space between ceiling and the floor is much worse than not having the duct taped.

No need for an ERV device? 400 to 600 CFM = a darn cold/Hot house when entertaining "Indoors"

How many BTUs are the burners and stove?? do you have outside combustion air supplied?

Why not just run the exhaust out next to the window, not even penetrate the ceiling??????

HOW DO THE HO's CLEAN THE RANCID GREASE OUT OF THE PIPING YOU CAN'T EVER REACH? Mice, Rats, maybe pigeons???

Hood Rat 04-29-2018 09:45 AM

Hi, I handle residential kitchen ventilation projects so I felt compelled to clarify a few things and support points made by others. The cabinet requires a door or removable panel for proper installation, service repair and inspection of a typical range hood "insert" (appliance industry name for guts of a hood shown in first pic). Most inserts are designed under the premise that they may be lifted and secured into an opening in the bottom of the cabinet, then ducted and wired by tradesman. Design for assembly. When not provided for by cabinet supplier, many inserts get hacked together. Flex duct, UGH! Don't alter the insert. You WILL violate the warranty! Make-up air - The single blower motor looks like it could be under 400 CFM but please take this seriously.

You have no idea how many appliances we cannot repair out West as compared to the East Coast due to poor labor and quality issues. The contractors starting from Texas on out to California especially, are garbage. Real shoddy-jerry riggin' work. Some stories you would not believe. I have to throw away a lot of good appliance repair jobs because, we would 1st have to remodel the kitchen in order to get to a customer's built-in jerry-rigged appliances. When doing business out-West be sure to work with Union labor. Its worth the price.
