Hi,
hoping you could take a look at these two diagrams and tell me if I need to install an aux vent to exterior above the roof or if I can use an aav in this case to satisfy code in ontario. Thanks for your assistance. Contractor gave me conflicting advice each time we talked so I'm not satisfied he knows whats what.
