INSTALLING DUCTS GOING TO / FROM OUTSIDE
PRACTICAL
TIPS
• Decide where your intake and
exhaust hoods will be located.
Locating the Intake
Weatherhood
• Should be located upstream (if
there are prevailing winds)
from the exhaust outlet
• At least 4' - 6' (2m) from the
exhaust weatherhood
• At least 6' (2m) away from
dryer vents and furnace
exhaust ( medium or high effi-
ciency furnaces)
• A minimum of at least 6' (2m)
from driveways, oil fill pipes,
gas meters, or garbage con-
tainers
• At least 18" (457mm) above
the ground
• At least 3' (1m) from the cor-
ner of the building
• Do not locate in a garage, attic
or crawl space
Locating the Exhaust
Weatherhood
• At least 6' (2m) from the
ventilation air intake
• At least 18" (457mm) above
ground
• At least 3' (1m) away from the
corner of the building
• Not near a gas meter, electric
meter or a walkway where fog
or ice could create a hazard
• Not into a garage, workshop
or other unheated space
When installing the weather-
hood, its outside perimeter
must be sealed with exterior
caulking.
A well designed and installed ducting system will allow the ERV to operate at its maximum efficiency.
Always try to keep duct runs as short and straight as possible.
See Installation Diagrams for installation examples.
INSTALLING THE DUCTING
TO THE WEATHERHOODS
The inner liner of the flexible insulated duct
must be clamped to the sleeve of the weath-
erhoods (as close to the outside as possible)
and to the appropriate port on the ERV. The
insulation should remain full and not be
squished. The outer liner, which acts as a
vapor barrier must be completely sealed to
outer wall and the ERV using tape and or
caulking. A good bead of high quality caulk-
ing (preferably acoustical sealant) will seal
the inner flexible duct to both the ERV port
and the weatherhood prior to clamping.
To minimize air flow restriction, the flexible
insulated duct that connects the two outside
weatherhoods to the ERV should be stretched
tightly and be as short as possible.
Twisting of folding the duct will severely
restrict air flow.

1 Using the collar of
the outside hood,
outline the intake &
exhaust holes to be
cut. The holes should
be slightly larger than
the collar to allow for
the thickness of the
insulated flexible
duct. Cut a hole
for both the intake
and exhaust hoods.
