Found an interresting hood issue the other day.... the fire suppression company had been signing off on the hood and fire suppression system for years. (Before my time) .

Had a small problems with getting the hood cleaned and started digging ----

this is what our office found that had been approved by somebody in 1996 ----- enjoy the pictures Bon appetit !!!

For the newbies, start listing the violations for the install if it were installed using today's codes - Please make refrence to application code when posting please -- i.e. 2006 IFC or NFPA 96, etc.
 
Reminds me of a client, now out of business. After several cleanings, I got enough grease removed and found screws holding an elbow to something. I removed the screws and the elbow. I found 1/2 plywood as part of the duct system. At least there were no penetrations through the plywood. The duct tape holding the rest of the duct was in good shape.

We went to my girlfriends class reunion, the festivities were held in a local resturant. The person in line ahead of me was the insurance agent who had the account. I asked if the cardboard hood made it difficult to get insurance. I got a blank look. The hood was made of cardboard and duct tape. Nice taping job. And the grease vapors from the fryer did go up into the hood, so the draft worked OK.

I did look as far back as the 1988 Mechanical Code and found only referenes to metal hoods, metal ducts and 18" clearances. I think I would require them to paint the wood with silver paint. That should make everything OK.
 
Primer grey is only approved for carboard ducts above a Type II hood - carboard used in grease ducts must covered by metalic (or high gloss) grey. :)
