Description from the creator

The point we are trying to make is that OEM's state in their installation manuals that static pressure levels above .60 wci in a duct run are not acceptable, yet the present code could technically approve a duct run that amounts to 1.25 wci of pressure.

How is that possible? For two main reasons; the termination hoods have no governing criteria as it relates to static pressures they create, and the typical ell the trade uses creates much more pressure than what the code 5 foot reduction penalty implies.

How we figured:
The use of a 4" x 4" gooseneck roof vent (.70 wci), 25 feet of pipe at .01 wci per foot (.25 wci), two standard ells at .15 each (.30 wci)
