What is wrong with this picture?

Somebody went to a lot of trouble to install this ansul system inside a Gaylord hood. Lots of holes drilled through the stainless Gaylord waterwash hood. No tag on it....Hmmm

They placed the links inside the plenum (behind the fire damper).

It seems wrong to me.

Doug I am sure you know.

Almost looks like you posted the pictures upside down.lol
Somebody did a shotty install.
Heat rises, So links should be at the top foremost point of the hood.
Behind the damper is no good. In the center bottom of the exhaust duct maybe.

Looks like they went with the easiest install procedure. Didnt have to worry about cutting any more conduit or working around fire system pipes.
Installed by owners poeple? Definetly not properly placed.
Washdown hoods are a waste of money. I have yet to see one that can do a adequite job. Better call the hood cleaner!
 
I cleaned a restaurant last year that had bought old hoods and had them installed. They had bought used Gaylord Water Wash hood and had converted them into regular hoods. The problem is that in the back of the hood they had just cut the drain pipes and left them uncovered, so if you cleaned the hood all of the water would drain behind the hood between the wall and the stainless steel back wall.

Needless to say it was a huge mess.

I think sometimes they try to save money by salvaging an old hood, but get it half installed for cheap, and no inspector catches it.

Good eye.
 
If you compromise the stainless on a Gaylord hood (ie. drilling holes in it) it loses its UL listing!
 
I don't get the feeling they were too concerned. It's one of those things that are hidden behind stainless steel panels and "what you don't see, can't be fined" attitude.

I'm surprised they even sell a used water wash hood to be installed as anything but a water wash hood. But I guess I don't know the used hood business that well.
 
1 The system looks to be a Pyro Chem, not Ansul. The plenum nozzle is mounted OK
2. the link holder is upside down. It is upside down because they mounted in too low in the plenum, they wanted the link holder to match the contour of the sheet metal
3. The link holder is out of the air stream, the activation of the system will be delayed.
4. The link holder at the duct entrance will be a bithch to service.
5. I have put sytems in some Gaylord hoods, the last 2 were in hospitals. I had the water wash deactivated during the fire suppression activation.
6. If the water wash is active, the chemical will cause rapid deteriation of the corner pulleys. This will cause the system to not activate. Only Amerex has a mechnical detection system that does not use corner pulleys.
7. Arn't Gaylord Hoods a pain to clean? One of our accounts has a Gaylord water Wash over a charbroiler. The first time we cleaned the hood, every time my helper carried stuff up the 2nd floor kitchen, he put chemical on it. Every time I carried stuff up the the 2nd floor kitchen, I put chemcal on it. Neither of use knew the other was squiting chemical in the hood. After plugging up the drain as least 3 times, we figured the hood was clean. We did the tear-down, polished the Stainless, and were ready to leave. I stuck my hand up the hood and pulled down a glob of grease the size of my fist. It took 3 years before I was pleased w/the job. Last year I got them to let me service the Gaylord water wash. There are 7 hoods w/water wash. $3693.75
later, a bunch of nozzles(some replaced 3 times) and now the water wash hoods actually work, somewhat. More or less, as well as a water wash will ever work

Doug,

I agree with you on this one. As long as the nozzles are working and you got the right chem in the water wash system, in general, they are the easiest to clean of all hoods.

But you get some plugged nozzles, or if it's not being operated regularly, or they're too cheap to buy the right chems, then it just slowly breaks down and is a real pain to clean.

Too many corners that can't be sprayed properly and cleaned to my satisfaction.
 
Doug,

Good information. Thanks.
If I get the job in question I will bring this to the customer's attention.

Rusty is right....when they are working somewhat correctly the systems are pretty easy to clean. But when they have been neglected they can be a huge pain in the ass.
Most places don't bother to have them serviced, nozzles changed etc...sometimes they think replacing the pump and/ or keeping soap in the panel is all that is required.

Here are some photos of another Gaylord system I saw last week.

el Jefe, What you have posted is a picture of the new self cleaning system that is now being marketed by Gaylord. the proof is the small bit of sheet metal you see under the grease. When the grease reaches the proper depth, it just falls off. with a bit more experience, you will learn to recognize this particular hood.
