3. INSTALLATION (CONT’D)
3.7 INSTALLING THE EXTERIOR HOODS
Choose an appropriate location for installing the exterior hoods:
• At a minimum distance of 6 feet (1.8 m) between the hoods to
avoid cross-contamination
• At a minimum distance of 18 inches (457 mm) from the ground
VD0028
Make sure the intake hood is at least 6 feet (1.8 m) 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.
Refer to illustration at right for connecting the insulated duct to the
hoods. An “Anti-Gust Intake Hood” should be installed in regions
where a lot of snow is expected to fall.

3.8 CONNECTING THE DRAIN
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 outside temperature typically remains below -25°C (-13°F), (over a 24-hour
period) for several days in a row, combined with an indoor humidity of 40% or higher.
3.8.1 HRV UNITS
Cut 2 sections of the plastic tube, minimum
12” long, and attach them to each inner drain
fitting, located under the unit.
Join both short sections to the “T” junction
and main tube as shown, to prevent the unit
from drawing unpleasant odors from the drain
source.
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.
SOLO UNITS ONLY
Insert both drain plugs (included in parts
bag) in alternate drain fittings located on top
of the unit.
