9. INTERIOR DUCTING
Ducting to the central forced air ductwork system, or if used, a dedicated duct system, should be
made of galvanized metal whenever possible.
To minimize airflow losses, runs should be kept as short as possible using 45 degree elbows
instead of 90 degree. Whenever possible use “Y” fittings instead of “T” fittings.
All joints must be fastened with screws, rivets or duct sealant and wrapped with a quality duct
tape to prevent leakage. If standard grills are used, it is recommended that wall grills of not less
than 6” x 12” and floor grills of no less than 4” x 10” be used to minimize air flow restrictions.
10. FRESH AIR SUPPLy DUCTING
Fresh air supply ducting to the living space may be either a dedicated or an indirect duct system.
Please refer to figures I and II.
Should the indirect method be used it is suggested that at the point of connection to the HRV
that a short length of flex duct be used to electrically isolate the two systems.
Fresh air supply grills may be either wall or ceiling mounted. Avoid locating these grills where
room occupants may be exposed to the fresh air supply as this air temperature may be slightly less
than the room air temperature.
Also, it is recommended that adjustable grills such as round “Tech Grills” be used to permit
balancing of the ventilation by room application.
It is recommended that a breathing “T” be installed in the fresh air duct between the HRV and the
central distribution system. This will maximize efficiency, but hard connection is acceptable.
