2. TYPICAL INSTALLATIONS
Use the following illustrations as guidelines to help you decide on how the unit will be installed.
The unit should be hung from the joists.
If required, bathroom fans and a range hood may be used to exhaust stale air. Also, for homes
with more than one level, we recommend one exhaust register at the highest level.
There are 2 installation methods: Fully ducted and Central Draw Point.
NOTE: An electrical outlet has to be available within 3 feet of the unit.
2.1 FULLY DUCTED SYSTEM
(PRIMARILY FOR HOMES WITH RADIANT HOT WATER OR ELECTRIC BASEBOARD HEATING)
Stale air coming from the registers located at the highest level
of the house is exhausted to the
outdoors.
Fresh air from outside is filtered
and supplied by the register located
in the lowest liveable level.
Homes with more than one
level require at least one exhaust
register at the highest level.
See figure at right.
VH0081

2. TYPICAL INSTALLATIONS (CONT’D)
2.2 CENTRAL DRAW POINT (CONNECTION TO A FORCED AIR SYSTEM)
Stale air coming from the
registers located at the highest
level of the house is exhausted to
the outdoors.
Fresh air from outdoors is filtered
and supplied to the return (plenum)
or the supply duct of the forced air
unit. See figure at right.
For this type of installation, it is not
essential that the forced air system
blower runs when the unit is in
operation, but we recommend it.
NOTE: Home with multiple forced
air systems should have
one unit on each system.
VH0082
3. INSTALLATION
3.1 INSPECT THE CONTENT OF THE BOX
Inspect the exterior of the unit for shipping damage. Ensure that there is no damage
to the door, ports, power cord, etc.
3.2 LOCATING THE UNIT
Choose an appropriate location for the unit.
• Within an area of the house where the ambient temperature is between 10°C (50°F)
and 50°C (122°F) (basement, furnace room, closet, etc.)
• Away from living areas (dining room, living room, bedroom), if possible
• So as to provide easy access to the interior of the unit, for maintenance
• Close to an exterior wall, so as to limit the length of the insulated flexible duct to
and from the unit
• Away from hot chimneys and other fire hazards
• Allow for a power source (standard
3-prong grounding outlet)
• Close to a drain. If no drain is
close by, use a pail to collect run-off
Slightly bend all 4 hooks located
on both sides of the unit in order
to hang it to ceiling joists with the
4 chains and springs provided.
See illustration beside.
CAUTION
Make sure the unit is level.

3. INSTALLATION (CONT’D)
3.3 PLANNING OF THE DUCTWORK
• Keep it simple. Plan for a minimum of bends and joints
• Keep the length of insulated ducts to a minimum
• Do not ventilate crawl spaces or cold rooms. Do not attempt to recover the exhaust air
from a dryer or a range hood. This would cause clogging of the filters and recovery
module
• If the house has two floors or more, be sure to plan for at least one exhaust register
on the highest lived-in level
3.4 INSTALLING THE DUCTWORK AND REGISTERS
3.4.1 FULLY DUCTED SYSTEM (AS ILLUSTRATED IN SECTION 2.1)
!
WARNING
Never install a stale air exhaust register in a closed room where a
combustion device operates, such as a gas furnace, a gas water
heater or a fireplace.
Stale air exhaust ductwork
• Install the stale air exhaust registers where the contaminants are produced:
kitchen, living room, etc. Position the registers as far from the stairway as possible
and in such a way that the air circulates in all the lived-in spaces in the house
• If a register is installed in the kitchen, it must be located at least 4 feet (1.2 m) from
the range
• Install the registers 6 to 12 inches (152 to 305 mm) from the ceiling on an interior
wall OR install them in the ceiling
• If possible, measure the velocity of the air flowing through the registers. If the
velocity is higher than 400 ft/min (122 m/min), then the register type is too small.
Replace with a larger one
Fresh air distribution ductwork
• Install the fresh air distribution registers in bedrooms, dining rooms, living room
and basement
• Keep in mind that the fresh air registers must be located as far as possible from the
stale air registers
• Install the registers either in the ceiling or high on the walls with air flow directed
towards the ceiling. (The cooler air will then cross the upper part of the room and
mix with room air, before descending to occupant’s level)
• If a register must be floor installed, direct the airflow up the wall
