Exterior ducting installation

weatherhood Location

•   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 a minimum of 2m (6’) away from dryer vents and furnace exhaust 

(medium or high efficiency furnaces), driveways, oil fill pipes, gas meters, 
or garbage containers.

• At a minimum height of 460 mm (18’’) above the ground, or above the 

level of expected snow accumulation.

• At a minimum distance of 1m (3’) from the corner of the building.
• Do not locate in the garage, attic, crawl space, or underneath deck.

Locating the Exhaust weatherhood

•  At least 460 mm (18") above ground or above the depth of expected snow accumulation
• At least 1m (3’) 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
• Do not locate in a garage, workshop or other unheated space

Installing the ducting to the weatherhoods

A well designed and installed ducting system will allow the HRV to operate at its maximum 
efficiency. The inner liner of the flexible insulated duct must be secured to the sleeve of the 
weatherhood (as close to the outside as possible) and to the appropriate duct connection on the 
HRV. The insulation should remain full and not crushed. The outer liner, which acts as a vapor 
barrier, must be completely sealed to the outer wall and the HRV using tape and/or caulking. A 
good bead of high quality caulking (preferably acoustical sealant) will seal the inner flexible duct to 
both the HRV duct connection and the weatherhood prior to securing them.
To minimize airflow restriction, the flexible insulated duct that connects the two outside 
weatherhoods to the HRV should be stretched tightly and be as short as possible.
Twisting or folding the duct will severely restrict airflow.

See “Installation Diagram Examples” for installation examples.

  Using the duct connection of 

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

Push the hood into the opening 
and then attach the hood to the 
outside wall with mounting 
screws. 
Repeat the installation 
procedure for both the supply 
and exhaust hoods.

2

  Pull the insulated flexible duct 

through the opening until it is 
well extended and straight. 
Slide the duct’s inner vinyl sleeve 
over the hood duct connection 
and secure. Pull the insulation 
over the duct and pull the vapor 
barrier over the sleeve. Secure 
with appropriate tape or 
sealant.

  Using a caulking gun, seal 

around both hoods to prevent 
any leaks.
