Nope. There's direct vent boilers, but the vent discharge has to be above possible snow drift height; there's no specific height stipulated.
It certainly can't be discharged below grade.

Actually it's very specific thanks to your government.
NOAA can provide the historical max depth of snow accumulation for most areas. The 12" of clearance is above this depth.

Our local gas utility uses the 12" rule. Anything less, the furnace gets red-tagged.

I kinda disagree. As Kurt mentioned, snow drifts. Snowfall depth records don't account for drift heights.
Yep, read it. No height, and drifting is noted as a reason.

Here in the lovely Garden State, the anticipated snow level is 6 inches; so the vent termination must be 18 inches above the ground or roof.

You didn't mention who the manufacturer is, but this is Weil-Mclane's direct-vent requirements. I would assume they are all pretty much the same.
