CONNECTING THE DUCTS TO THE HRV

EXHAUST TO
OUTDOOR HOOD
Do not handle unit by
the collars / collar
openings to avoid
damaging the collars
& foam insulation.
INSTALLING DUCT TO HRV
Flexible Duct: Slide flexible ducting onto duct connection and affix with cable tie.
Solid Ducting: slide duct over duct connection, screw in place and seal.

SUPPLY AIR GRILLES LOCATION

Without a forced air furnace: fresh air should be supplied to all habitable rooms
from high wall or ceiling locations. Grilles that diffuse the air comfortably are
recommended.
With a forced air furnace: Connect to the furnace ductwork.

EXHAUST AIR GRILLE'S LOCATION

Draw stale air from the points where the worst air quality problems occur: bathroom,
kitchen, and laundry room. Additional return air ducts from strategic locations may
be installed. The furnace return duct may also be used to exhaust from.
As per building codes and installation requirements for combustion
appliances: Air return ducts, or openings for air return, should not be
placed in enclosed spaces containing combustion appliances that are
subject to spillage.

• Ducts should be kept short and have as
TO HOME
few bends or elbows as possible.
• 45º elbows are preferable to 90º.
• Use "Y" ducts instead of "T" ducts
whenever possible.
• All duct joints must be fastened with
screws or duct sealant and wrapped
with aluminum foil duct tape to prevent
leakage.
• Galvanized ducting from the HRV
to the living areas in the house is
recommended whenever possible.
• To reduce noise a short length
(approximately 300 mm, 12'') of
nonmetallic flexible insulated duct should
be connected between the HRV and the
supply/exhaust ductwork system.
• The main supply and return line to/from
the HRV must have the same diameter
as the duct connection or larger.
• Branch lines to the individual rooms may
be as small as 100mm (4'').
INSTALLING
THE DRAIN
Install the drain hose making a
"P" trap, secure the condensate
line drain to HRV by sliding into
connection. Fill the condensate line
with water.
