Consumer Information
A. To ensure quiet operation of the ENERGY STAR certified 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 significant 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 a simplified installation that operates your furnace air handler for room-to-room ventilation, an electrically efficient furnace that has an electronically commutated (EC) variable speed blower motor will minimize your electrical energy consumption and operating cost.
C. Installation of a user-accessible control with your product model will improve comfort and may significantly reduce the product model’s energy use.

2.2 INSTAll IN iG 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, fireplace 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.

2.2.1 FULLY DUCTED SYSTEM (T-i) (THIS CONFIGURATION ALLOWS RECIRCULATION MODE TO OPERATE.)
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.
    VENMAR A180H75RT Air Exchanger - fig6

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 airflow directed towards the ceiling.
  • If a register must be installed in the floor, direct the airflow up the wall.
    NOTE: For this type of configuration, the Ti option must be selected on the LCD screen when auto-balancing the unit.

2.2.2 EXHAUST DUCTED SYSTEM (T-2) (THIS CONFIGURATION ALLOWS RECIRCULATION MODE TO OPERATE.)
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.
STALE AIR FROM MOLDING:
Same as for Fully Ducted System, described on point
2.2.1. 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+BY.
  • This 10-ft. distance applies only in areas where the outside temperature falls below the freezing point 0°C (32T).
    NOTE: The central forced-air system blower operation can be synchronized with the unit (see Section 3.3). It is recommended, but not essential that the central forced-air system blower runs when the unit is in operation.

2.2.3 simplified insTAllATion (T-4) (THis confiGurATion does noT Allow recirculATion mode To operATe.)

CAUTION
The central forced-air system must be synchronized with the unit since fresh air evacuation and distribution come from the same section. The central forced-air system must operate to avoid fresh air to be directly drawn by the evacuation, which would reduce significantly fresh air supply to the building. See Section 3.3 for ducting.
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 flow through the central forced-air system ducts, which simplifies 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 forcedair 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   ntral forced-air system (A+B)*.

2.4 insTAllinG THe exTerior Hoods

To avoid cross-contamination:

  • Keep at least 6 feet between both hoods.
  • 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 efficiency 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 significantly degrade the quality of the incoming air which, in some cases, could result in health consequences.
    In the event of a conflict between our conditions and local requirements, the latter will have priority.

VENMAR A180H75RT Air Exchanger - fig12

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.

2.5 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 flexible ducts to the ports of the unit (exhaust to outside and fresh air from outside).

  1.  Expose the flexible duct by pulling back the insulation, and place it over the inner port ring.
  2. Attach the flexible 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.

VENMAR A180H75RT Air Exchanger - fig13

TrAnsiTioninG To 8-in. ducTs
If using 8-in. ducts, install 6-in. to 8-in. transitions on the ports, and secure using duct tape only. If rigid ducting is used, install a 12-in. section of flexible 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 flexible duct to connect rigid ducts to the unit. To connect insulated rigid ducts to the unit (cold side) using insulated flexible ducts, follow instructions in section 2.4. To
connect regular rigid ducts (warm side) to the unit using non-insulated flexible ducts, use a tie wrap.
NOTE: It is recommended to use 8″ ducting instead of 6″ ducting if required airflow is over 200 CFM and long run of ducting or high quantity of elbows is used. It will prevent having too high static pressure in the ducting.
IMPORTANT: Make sure to connect ducting as illustrated below to get airflows reading accuracy. Correct installation will also allow proper drainage of water that may accumulate in ducting.

CORRECT  INSTALLATION

VENMAR A180H75RT Air Exchanger - fig14

CAUTION
Ducting must not be too crushed. Otherwise, airflows reading accuracy will be affected.
CAUTION
Insulated ducts must have the same diameter as the ports to ensure proper drainage of water that may accumulate in ducts.

INCORRECT INSTALLATION

VENMAR A180H75RT Air Exchanger - fig15

NOTE: Route ducts as straight as possible, minimize the number of elbows and design and install ducts in accordance with HRAI best practices.
