Sent: Friday, May 30, 2014 2:32 PM To: [email protected] Subject: Re: Hibachi grills The plenum/duct interface is the most dangerous place in the hood/plenum/duct assembly but it's a Class I Hood System (combustible/flammable vapors) and so weld sealed along it's entire length. Mechanical codes require that the duct be insulation wrapped under certain circumstances (this is a Drucker for sure, I've only seen this wrapping in high-rise and within concealed spaces, but I hesitate to say that's the "WHY" as I've never studied cod on this). This sounds like you are required to either have sprinklers in the plenum (which would necessitate a penetration--bad juju), or that they want the area outside the duct/plenum interface protected for the probably "happened once and we're damned sure not gonna have that happen again" fire solution. The route of greasy vapors is collected by the hood and then enters the hood duct system which is a separate fire area until it encounters some sort of air scrubber or exits the building (a minimum ten feet from any property line). I love cooking, eating, cooking history, recipes, cooking fires, both controlled and not, and cooking/restaurant fire protection. And a good shot of single malt or a quality mezcal. That's a hint should any of you ever happen to be where I am and there's a bar close by }:-P On Fri, May 30, 2014 at 11:16 AM, Steve Mackinnon <[email protected]> wrote: > Thank you Ron. > The exhaust duct reduces to a third of its size within the plenum > (above the grill hood), and the mechanical code is locating the > upright heads outside of the duct in the cavity created by the > reduction.
