Question: On the attached picture (condensate for HRV and Furnace): Do I have to vent through the roof?
Interpretation: (On. Reg. 403/97) Section 220.127.116.11(3) indicates that the vent must go through the roof when fixtures are on 3 or more stories. Traps are required to prevent air flow from one unit to another on adjacent levels.
