Design and installation of ductwork must be according to
standard HVAC practice to deliver required quantities of fresh
air to temperature-controlled space and exhaust equivalent
quantities of room air to the outside.
Keep intake and exhaust duct runs as short as possible with
few bends or elbows.
• Keep duct sizes as large as possible throughout the
installation.
• Use a 6 in. diameter round duct for all connections to and
from the ventilator.
• Separate outside intake and exhaust vents by at least
6 ft (2m).

ventilator to the return air plenum of the air handler is an
excellent way to distribute fresh air and exhaust stale air
from all parts of the house, while reducing installation costs.
When choosing this method, balance the ventilator when
the air handler is running and interlock the ventilator so that
it can run only when the air handler runs. See Fig. 6. An
alternate method is to balance the ventilator when the air
handler is not running and let the ventilator run whether the
air handler is running or not, see Fig. 7. An independent
installation is shown in Fig. 8.

handler operates, fresh air is distributed through the
heating/air conditioning supply registers. When the air
handler is off, fresh air is delivered through both sup-
plies and returns.
