I am building a new house (floor plan attached) and will install an IS on a raised hearth outside the 2nd bedroom. I would appreciate your thoughts about using an OAK. The house will have a full 9' walkout basement, spray foam insulation (r. 30 fiberglass between basement and 1st floor), and Marvin Integrity windows. Competitors for air: the bath exhausts will be on an HRV system, and the 2nd bath will rarely be used, the kitchen may have outside venting, but it will rarely be used, the electric dryer will be used once a week, and the high efficiency propane boiler in the basement will have intake and vent pipes that terminate outside the house. Although I would rather not use an OAK, I certainly want the stove to operate properly.
1. Use an OAK--necessary/advisable/optional?
2. If OAK, can I draw combustion air from the basement, or does that present problems, negative pressure or otherwise?
3. If I terminate the OAK outside the house, would it be better to go down to the basement, and then straight out the east wall (under the 2nd bedroom) (long horizontal run, but only 1 90 degree bend), or down to the basement east a few feet, then south and out somewhere under the front porch (shorter horizontal run, but 2 90 degree bends.)
Many thanks.
