1 Begin with the duct collar marked “Exhaust Air In”. Slide a short piece
(12”) of flexible duct over the duct collar. Using duct tape, tape the
flexible duct to the collar. Run the flexible ducting to the main rigid duct
trunk line, which connects to the remainder of the ducts going to and
from rooms in the house. Repeat the steps for the “Supply Air Out” on
the side of the HRV.

Exhaust Air Ducting
The stale air exhaust system is used to draw air from the points in the house where the worst air quality problems occur. It is rec-
ommended that return air ducts be installed in the bathroom, kitchen, and laundry room. Additional return air ducts from strategic
locations (i.e. greenhouse, atrium, swimming pool, sauna, etc.) may be installed. The furnace return duct may be also used to
exhaust from. In this method, the exhaust air is not ducted back from bathrooms, kitchens, etc to the HRV with “dedicated lines”.
This method has become popular and provides good ventilation when installed in accordance with the instructions. The furnace
blower must be running when the HRV is operating for this method to be effective.
