Flue Gases in attic

[Mike Schulz]

Codeman,

Inspected a ranch home today that had a direct vent fireplace. The exhaust hood on the exterior was up under the eave and was in compliance for distance to the perforated soffit. I turned on the fireplace and let it run the whole time I was there. When I went into the attic the smell about knocked you out from the flue gasses being sucked through the soffit. The builder was there and claims it is a energy star home and the that attic is sealed from habitable areas. He also claims the gases in the attic pose know risk and is allowed. It just doesn't sit well with me and I think it's a risk of leakage into the home.
Is there any code that says no gases in the attic?
