Consumer Information
A. To ensure quiet operation of the H/ERV, each product model must be installed using sound attenuation techniques appropriate for the installation.
B. The way your heat/energy-recovery ventilator is installed can make a signifi cant difference to the electrical energy you use. To minimize the electricity use of the heat/energy-recovery ventilator, a stand-alone fully ducted installation is recommended. If you choose to connect the H/ERV to the ducting of your furnace air handler for room-to-room ventilation, an electrically effi cient furnace that has a variable speed blower motor will minimize your electrical energy consumption and operating cost.

2.4 INSTALLING THE DUCTWORK AND THE REGISTERS
WARNING
Never install a stale air exhaust register in a room where there is a combustion device, such as a furnace, gas water heater, fi replace or any appliance or equipment that can generate gaseous contaminants, or pollutants. The negative pressure this could create in the room may impair proper evacuation of the gas or pollutants, which may have severe health consequences.
CAUTION
If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts to prevent condensation formation inside and outside ducts, which could cause material damage and/or mold growth. Moreover, if fresh air to building duct and/or stale air from building duct goes/go through an unconditioned space, the unit must be set to operate continuously in cold conditions (below 10°C/50°F). Continuous air movement inside ducts will prevent condensation formation. The unit can be stopped temporarily for maintenance and/or repair purposes in such conditions.
In every case, bathroom fans and a range hood could be used to exhaust stale air. However, please note that an optional bathroom installation kit (no. IKBV1000 for Venmar units) is available for houses where there is no bathroom fan.
2.4.1 FULLY DUCTED SYSTEM (PRIMARILY FOR HOMES WITH RADIANT HOT WATER OR ELECTRIC BASEBOARD HEATING)
STALE AIR FROM BUILDING:

• Install registers in areas where contaminants and humidity are produced: kitchen, bathrooms, laundry room, etc.
• Install registers on an interior wall, 6 to 12 inches away from the ceiling OR in the ceiling.
• Install the kitchen register at least 4 feet away from the range.
• Bathroom fans and range hoods can be used to better exhaust stale air.
• Homes with more than one level require at least one exhaust register at the highest level.

FRESH AIR TO BUILDING:

• Install registers in bedrooms, dining room, living room and basement.
• Install registers in the ceiling OR high on the walls with the airfl ow directed towards the ceiling.
• If a register must be installed in the fl oor, direct the airfl ow up the wall.

2.4.2 EXHAUST DUCTED SYSTEM (DUCTING TO A FORCED AIR SYSTEM)
WARNING
Duct connection to the central forced-air system can be regulated by some codes and standards. It is your
responsibility to consider and comply with your local requirements to avoid any non-compliance.
CAUTION
Do not connect the unit to any forced air system distribution duct.
STALE AIR FROM BUILDING:
Same as for Fully Ducted System, described on point 2.4.1.
FRESH AIR TO BUILDING:

• Connect the fresh air distribution duct of the unit to the central forced-air system return duct at least 10 feet away from the central forced-air system (A+B)*.

• This 10-ft. distance applies only in areas where the outside temperature falls below the freezing point 0°C (32°F).
  NOTE: It is recommended, but not essential that the central forcedair system blower runs when the unit is in operation. NOTE: A home with multiple forced air systems should have one unit on each system.
  2.4.3 SIMPLIFIED INSTALLATION (DUCTING TO A FORCED AIR SYSTEM)
  CAUTION
  The central forced-air system blower must always be in operation when the unit is running since fresh air evacuation and distribution come from the same section. The central forced-air system blower must operate to avoid fresh air to be directly drawn by the evacuation, which would reduce signifi cantly fresh air supply to the building.
  CAUTION
  Do not connect the unit to any forced air system supply duct.
  WARNING
  Duct connection to the central forced-air system can be regulated by some codes and standards. It is your responsibility to consider and comply with your local requirements to avoid any non-compliance.
  Fresh air and exhaust air fl ow through the central forced-air system ducts, which simplifi es the installation.
  The use of bathroom fans and a range hood is suggested to exhaust stale air.
  STALE AIR FROM BUILDING:
  Connect the stale air intake port of the unit to the central forced- air system return duct at least 3 feet ahead of the fresh air distribution from the unit.
  FRESH AIR TO BUILDING:
  Connect the fresh air distribution duct of the unit to the central forced-air system return duct at least 10 feet away from the central forced-air system (A+B)*.

• This 10-ft. distance applies only in areas where the outside temperature falls below the freezing point 0°C (32°F).
  NOTE: A home with multiple forced air systems should have one unit on each system. 2.5 CONNECTING THE DRAIN (HRV ONLY)
  CAUTION
  Install the drain hose included and run it to a drain or a pail. This unit may generate a large amount of water in cooler weather. It is necessary to install the drain hose properly to prevent water damage and/or material damage.

  • Cut the appropriate lengths of drain tubing (see illustration at right).
  • Connect the tubings to the provided adaptor.
  • Make a water trap loop in the tube to prevent the unit from drawing unpleasant odors from the drain source.
  • Add water in the loop to prevent noise or hiss.
  • Make sure there is a distance of at least 2″ between the unit and the tubing loop (see illustration at right).
  • Using the tie wraps provided, attach the tubing as illustrated below.
  • Run the tube to the fl oor drain or to an alternate drain pipe or pail.
  • IMPORTANT: If using a pail to collect water, place the tube end approximately 1″ inside the pail in order to prevent water from being drawn back up into the unit.

2.6 INSTALLING DUAL EXTERIOR HOOD USING TANDEM® TRANSITION KIT (OPTIONAL)
For units set at 110 CFM or less, a Tandem transition kit can be used instead of 2 exterior hoods; but take into account this device will generate approximately an additional 0.2 in w.g. static pressure depending on the installation.
The minimum joist opening needed to install the Tandem® transition is 9¾”. The maximum height of the Tandem transition is 8¾”.
To connect the insulated fl exible ducts to the Tandem transition (Exhaust air to outdoors and Fresh air from outdoors), follow the instructions included with the Tandem transition kit (part no.14690), included in IKSV1000 kit. CAUTION
Select TANDEM speed setting to use this transition kit with your unit. See section 4 for more details.
2.7 INSTALLING THE EXTERIOR HOODS
To avoid cross-contamination:

• Keep at least 6 feet between both hoods OR use approved combined hoods model 14690.
• Install hood(s) at least at 18 inches away from the ground OR depth of expected snow accumulation, whichever is greater.

WARNING
Make sure intake hood is at least 6 feet (1.8 m) away from any of the following:

• Dryer exhaust, high effi ciency central forced-air system vent, central vacuum vent
• Gas meter exhaust, gas barbecue-grill
• Any exhaust from a combustion source
• Garbage bin and any other source of contamination.

Ignoring these recommendations could signifi cantly degrade the quality of the incoming air which, in some cases, could result in health consequences.
In the event of a confl ict between our conditions and local requirements, the latter will have priority. Refer to illustration above for proper connection method of the insulated ducts to the hoods. An “Anti-Gust Intake Hood” should be installed in regions where a lot of snow is expected to fall.
2.8 CONNECTING THE DUCTS TO THE UNIT
CAUTION

• If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts to prevent condensation formation inside and outside ducts, which could cause material damage and/or mold growth.
• Do not use screws to connect the ducts or transitions to the ports so as not to interfere with ports inner dampers operation. A non-functioning damper could freeze the unit, which could cause damages.

INSULATED FLEXIBLE DUCTS
Use the following procedure to connect the insulated fl exible ducts to the ports of the unit (exhaust to outside and fresh air from outside).

1. Expose the fl exible duct by pulling back the insulation, and place it over the inner port ring.
2. Attach the fl exible duct to the port using a tie wrap.
3. Seal the joint using duct tape.
4. Pull the insulation and vapor barrier over the joint, tuck them between the inner and outer rings of the double collar and fasten them in place using duct tape.

CAUTION
The vapor barrier should remain intact and free of cracks or openings. An opening could produce condensation inside or outside duct, which could cause material damage and/or mold growth in the long run. TRANSITIONING TO 6-IN. DUCTS
If using 6-in. ducts, install 5-in. to 6-in. transitions on the ports, and secure using duct tape only. If rigid ducting is used, install a 12-in. section of fl exible duct between the transition and the rigid ducting (see above).
RIGID DUCTS
To prevent potential water leakage in cold side rigid ducting insulation, seal all rigid ducting joints with duct tape.
To avoid transmission of vibrations, always use a 12-inch section of fl exible duct to connect rigid ducts to the unit. To connect insulated rigid ducts to the unit (cold side) using insulated fl exible ducts, follow instructions in section 2.7. To connect regular rigid ducts (warm side) to the unit using non- insulated fl exible ducts, use a tie wrap.
2.8.1 DUCTS CONNECTION
IMPORTANT: Make sure to connect ducting as illustrated below to achieve the factory preset airfl ows. Correct installation will also allow proper drainage of water that may accumulate in ducting. CAUTION
Ducting must not be too crushed. Otherwise, factory preset airfl ows accuracy will be affected. NOTE: Route ducts as straight as possible, minimize the number of elbows and design and install ducts in accordance with HRAI best practices.

CONTROLS

WARNING
Electrical wiring must be done by qualifi ed personnel in accordance with all applicable codes and standards.
