5.3 PLANNING
OF THE
DUCTWORK
All units in this manual are prebalanced.
• Keep it simple. Plan for a minimum of bends and joints.
• Keep the length of outside insulated duct 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.

! 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.
• Install the stale air exhaust register in the main area where the contaminants are produced: kitchen, living room, etc. Position the
register 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 desired,
you can install another register (sold separately).
• If the register is installed in the kitchen, it must be located at least 4 feet (1.2 m) from the range.
• Install the register 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall OR install it in the ceiling.
Fresh / Filtered air distribution ductwork
• Install the fresh / filtered air distribution register in a large, open area in the lowest level to ensure the greatest possible air circulation.
Keep in mind that the filtered air register must be located as far as possible from the stale air register. If desired, you can install
another register (sold separately).
• Install the register in the ceiling OR 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall. The duct lenght should be
at least 15’ (4.6 m). (The filtered air will then flow through the room and mix with room air, ensuring a continuous renewed airflow.)

CAUTION
Make sure the vapor barrier on the insulated ducts does not tear during installation.
Use the following procedure for connecting the insulated flexible ducts to the Tandem® transition* (EXHAUST AIR TO OUTSIDE and
FRESH AIR FROM OUTSIDE).
NOTE: If the joists are perpendicular to the ducts, or if the connection to the exterior hood is in a limited area, your installation will need
two exterior hoods instead of one. In this case, do not use the Tandem® transition. Identify each insulated duct. For fresh air from
outside duct, use the blue sticker dots (one dot at each end). For exhaust air to outside duct, use the red sticker dots (one dot at each
end). (No dots for HRV 2600 and HR 2.6 units.) Then, go to point 5.5.2 and refer to the optional single hood enclosed instructions.
*Patented.
5.5.1 CONNECTION TO TANDEM TRANSITION
1. For each duct, pull back the insulation to expose the interior flexible duct.
2. Connect the interior flexible duct to the smaller part of the Tandem transition (5’’ oval) using a tie wrap.
NOTE: If you are using a 6’’ diameter insulated duct, use the bigger part of the Tandem transition (6’’ oval).
