3. INSTALLATION (CONTD)
3.7 INSTALLING TWO EXTERIOR HOODS
Choose an appropriate location to install the exterior hoods:
There must be a minimum distance of 6 feet between
the hoods to avoid cross-contamination.
There must be a minimum distance of 18 inches from
the ground.
Refer to figure at right for connecting insulated ducts to the
exterior hoods. An “Anti-gust intake hood’ should be installed
in regions where a lot of snow is expected to fall.
WARNING
!
Make sure the intake hood is at least 6 feet away
from any of the following:
Dryer exhaust, high efficiency furnace vent,
central vacuum vent
Gas meter exhaust, gas barbecue-grill
Any exhaust from a combustion source
Garbage bin and any other source of
contamination.
3.8 CONNECTING THE DRAIN
CAUTION
A drain tubing (included) must be installed for all HRV units. For ERV units, it is not required, however, it is
recommended for climates where the outdoor temperature typically remains below -13°F, (over a 24-hour period)
for several days in a row, combined with an indoor humidity of 40% or higher.

Make a water trap loop in the tube to prevent the unit from
drawing unpleasant odors from the drain source. Make sure this
loop is located OVER the “T” as shown. Run the tube to the floor
drain or to an alternative drain pipe or pail.
IMPORTANT
If using a pail to collect water, locate the tube end approximately
1” from the top of the pail in order to prevent water from being
drawn back up into the unit.
