Large Wood Burning Stove, Combustion Air

[mjpeisher]

All,
I have a large "commercial size" wood burning stove. (Kitchen is sized for approximately 750 people per meal, 3 meals per day) The kitchen has a hood currently over it, with exhaust and supply fans for the airflow.

Since this is a solid fuel burning appliance, with the combustion operation exposed to the room, I would think that the room needs to be positively pressurized to avoid backdrafting the carbon monoxide back into the room. If the room was negative, it would be the equivalent of having a large fire in the fireplace while the attic fan was on.

However, common sense tells me one thing, but I can't find a code to back it up. Anyone provide some direction here?

IMC/IPC/IBC/NFGC 2006?
ASHRAE Handbooks?

Anything would be helpful.
Thanks.

open fire?
I'd think negative pressure above the stove (the hood can do that). then slightly higher pressure in the kitchen, and then higher pressure in the remaining areas. If an open fire is even legal.
