(Primarily for homes with radiant hot water or electric baseboard heating.
See illustration at right.)
Moist, stale air is exhausted from the high humidity areas in the home, such as
bathrooms, kitchen and laundry room.
Fresh air is supplied to bedrooms and principal living areas.
If required, bathroom fans and a range hood may be used to better exhaust stale
air.
Homes with more than one level require at least one exhaust register at the
highest level.
2. TYPICAL INSTALLATIONS
2.1 FULLY DUCTED SYSTEM
There are three common installation methods.
VH0077
(For homes with forced air heating. See illustration at right.)
Moist, stale air is exhausted from the high humidity areas in the home, such as
bathrooms, kitchen and laundry room. Fresh air is supplied to the cold air return
or the supply duct of the furnace. If required, bathroom fans and a range hood
may be used to better exhaust stale air.
Homes with more than one level require at least one exhaust register at the
highest level.
NOTE: For this type of installation, it is not essential that the furnace blower runs
when the unit is in operation, but we recommend it.
2.2 EXHAUST DUCTED SYSTEM (SOURCE POINT VENTILATION)
VH0078
(For homes with forced air heating. See illustration at right.)
Fresh air and exhaust air flow through the furnace ducts, which simplifies the
installation.
The use of bathroom fans and a range hood is suggested to exhaust stale air.
NOTE: For this type of installation, the furnace blower must be running when
the unit is in operation.

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, door latches, door hinges, dampers,
duct collars, cabinet, etc.
• Inspect the interior of the unit for damage. Ensure that the fan motor assembly, recovery module, insulation, dampers, condensation tray
are all intact.
• If the unit was damaged during shipping, contact your local distributor. (Claim must be made within 24 hours after delivery.)
When applicable local regulation comprises more restrictive installation and/or certification requirements, the
aforementioned requirements prevail on those of this document and the installer agrees to conform to these at
his own expenses.
When performing installation, servicing or cleaning the unit, it is recommended to wear safety glasses and gloves.
3.2 LOCATING AND MOUNTING THE UNIT
Choose an appropriate location for the Unit:
• Within an area of the house where the ambient temperature is kept between 50°F and 104°F
• Away from living areas (dining room, living room, bedroom), if possible
• So as to provide easy access to the interior cabinet for every three months and annual maintenance, and to the control panel on the
side of the unit;
• Close to an exterior wall, so as to limit the length of the insulated flexible duct to and from the unit
• Close to a drain. If no drain is close by, use a pail to collect run-off
• Away from hot chimneys, electrical panel and other fire hazards
• Allow for a power source (standard outlet)
Hang the unit with the 4 chains and springs provided (see illustrations at right).
VD0037
VD0279
3.3 PLANNING OF THE DUCTWORK
a) Follow the instructions in Section 3.4 (next page) to determine the appropriate duct diameters for your system.
b) Keep it simple. Plan for a minimum number of bends and joints. Keep the length of insulated duct to a minimum.
c) Do not use wall cavities as ducts. Do not use branch lines smaller than 4” Ø.
d) 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 recovery module. Use sheet metal for the kitchen exhaust duct.
e) Be sure to plan for at least one exhaust register on the highest lived-in level of the house if it has 2 floors or more.
NOTE: Prior to installation of the unit, remove its shipping bracket by unscrewing its wing nut and
loosing its both retaining screws.

Use the table below to ensure that the ducts you intend to install will be carrying air flows at or under the recommended values.
Avoid installing ducts that will have to carry air flows near the maximum values and never install a duct if its air flow exceeds
the maximum value.
3. INSTALLATION (CONT’D)
3.4 CALCULATING THE DUCT SIZE
VI0003
PROBLEM:My installation requires two exhaust registers (one for the kitchen, one for the bathroom).
I will connect these registers to a main duct which will connect to the unit (high speed performance
value of 140 cfm). What size of duct should I use for the main exhaust duct and for the two end
branches leading to the registers? (See illustration at right.)
SOLUTION:Simplified method. (For a more detailed method of calculating duct size refer to the ASHRAE
or HRAI HANDBOOK).
Main duct: Table above indicates a 6” Ø duct: Recommended air flow: 120 cfm; maximum air flow:
180 cfm. The high speed air flow of 140 cfm is close enough to the recommended value (120) and
far enough away from the maximum value (180). Therefore a 6” Ø duct or larger is an appropriate
choice for the main exhaust duct.
End branches: Each end branch will have to transport an air flow of 70 cfm (140 divided by 2). Table
above indicates a 5” Ø duct: Recommended air flow: 75 cfm; maximum air flow: 110 cfm. The high
speed air flow of 70 cfm is close enough to the recommended value (75) and far enough away from
the maximum value (110). Therefore a 5” Ø duct or larger is an appropriate choice for the 2 end
branches.
NOTE: A 4” Ø duct would have been too small because the maximum acceptable value for a 4” Ø
duct is 60 cfm.

3. INSTALLATION (CONT’D)
3.5 INSTALLING THE DUCTWORK AND THE REGISTERS
STALE AIR EXHAUST DUCTWORK:
• Install registers in areas where contaminants are produced: Kitchen, bathrooms, laundry room, etc.
• Install registers 6 to 12 inches from the ceiling on an interior wall OR install them in the ceiling.
• Install the kitchen register at least 4 feet from the range.
• If possible, measure the velocity of the air flowing through the registers. If the velocity is higher than 400 ft/min., then
the register type is too small. Replace with a larger one.
FRESH AIR DISTRIBUTION DUCTWORK:
• Install registers in bedrooms, dining room, living room and basement.
• Install 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 level.)
• If a register must be floor installed, direct the air flow up the wall.
Never install a stale air exhaust register in a room where there is a combustion device, such as a gas furnace, a
gas water heater or a fireplace.
The ductwork is intended to be installed in compliance with all local and national codes that are applicable.

FRESH AIR DISTRIBUTION:
3.5.2 EXHAUST DUCTED SYSTEM (AS ILLUSTRATED IN SECTION 2.2)
There are two methods for connecting the unit to the furnace:
METHOD 1: SUPPLY SIDE CONNECTION
• Cut an opening into the furnace supply duct at least 18 inches
from the furnace.
• Connect this opening to the fresh air distribution port of the HRV/ERV
(use metal duct, see illustration at right).
• Make sure that the HRV/ERV duct forms an elbow inside the furnace ductwork.
• If desired, interlock (synchronize) the furnace blower operation with
the HRV/ERV operation. (See Section 5).
When performing duct connection to the furnace, installation must be done in accordance with all applicable
codes and standards. Please refer to your local building code.
When performing duct connection to the furnace supply duct, this duct must be sized to support the additional
airflow produced by the ERV/HRV. Also, use a metal duct. It is recommended that the ERV/HRV is running when the
furnace is in operation in order to prevent backdrafting inside ERV/HRV.
