hello my name is jason,
i am working closely with a friend(builder) building a 3000 sq ft home. i opted for foam insulation and zero clearance wood burning stove. the idea being to heat most of the house with the stove. the hvac contractor (supposedly knew) i was foam insulating but now says he didnt know. we went with an 80% lennox unit with the thought we didnt need a 90% due to the stove. the insulation guy told me i needed a 90% because of the foam and fresh air issues. i have the feeling my builder and/or the hvac guy wont say they made a mistake. now my builder states i can build plywood boxes over my units and pipe in fresh air for the 80% unit. sounds funny to me.
if anyone knows what i need to do please *! thank you
