I just got a plan, stamped by an engineer, for a site built, UL listed, wood fired pizza ovem with nothing more than double wall 8" pipe coming out the top and no hood. the Serno Plate for the unit specifically states that the cooking equuipment is to be provided with an exhaust hood. The plans also indicate to comply with building code, mechanical code and local etc etc...

I'm thinking seperate hood required?
 
Normally direct vent to outside, like a fireplace,

Unless some reason they can't do that , the. Yes vent a hood
 
The picture that has the completed red colored unit sitting in the parking lot looks like something from Jack and the Beanstock, like this would be something the giant would have in his castle in the sky.
 
plan shows an 8" double wall out the top of the unit. It seems to contradict the plate affixed to the unit stating that the equipment shall be equiped with an exhaust hood . Maybe the 8" is enough?

Does IMc allow direct venting???

Thought this question has been talked about before
 
Fire department telling me no suppression and no hood per NFPA 96. Combine that with engineer stamped plan calling for no hood and direct vent, I think that's where we are going.
 
"the Serno Plate for the unit specifically states that the cooking equuipment is to be provided with an exhaust hood." From the original post.

If the manufacturer of the oven requires a hood, I don't see how you can not require one. It would violate the listing of the oven.

Isn't this part of the assembly?

NFPA 96 is not a referenced standard in any of the I-Codes. Is it a Massachusetts ammendment. Or does the manufacturer refreance it in their installation instructions?
 
according to FD

Trust but Verify

Worked with to many FD officials who shot from the hip when it came to application of the correct code.

304.2 Conflicts.

Where conflicts between this code and the conditions of listing or the manufacturer's installation instructions occur, the provisions of this code shall apply.

Exception: Where a code provision is less restrictive than the conditions of the listing of the equipment or appliance or the manufacturer's installation instructions, the conditions of the listing and the manufacturer's installation instructions shall apply.
 
It sounds like what you have there is a double wall flue that connects to a class A vent (chimney). I doubt that this would simply dump into a hood, although I would say that a suppressions system would be in order. Go to the most restrictive between the manufacturer's specs and the code.

NFPA 96 referenced in the Oregon Fire Code has a state amendment. Sounds like you have trust issues with the local fire official.
