I am designing a combustion air sys

I am designing a combustion air sys

(OP)
I am designing a combustion air system for a residential home.  The Mechanical room has appliances that total 573,000 btu/hr.  The General Contractor has suggested that we place two openings (12"x12")in the mechanical room wall that will feed into a small storage room that will have one large louvered opening (18"x18")in an exterior wall (the louvers will be interlocked to the Gas Valves on all appliances).  I have read through the Uniform Mechanical Code 2000 edition several times, and I can't determine if this is up to code.  Any thoughts?

RE: I am designing a combustion air sys

I do not know if you have had this thread answered yet, but here goes.  According to the 2000 International Mechanical Code Appendix A, this would be considered as "All air from outdoors through horizontal ducts or direct openings" and requires 2 openings (1 at no more than 12" below the ceiling of the mechanical room and the other at no more than 12" above the floor of mech room), each having at least 1 sq. in. per 2,000 BTU.  With the BTUs you gave each opening would need to be at least 16.5" square.  This would include both the interior wall and the exterior wall.

Hope this helps and is not too late.
