6 .6 Installing the Ducting
Observe the following conditions when installing the
ducting:
• Ducting must be appropriately sized for your
application.
• Run ducting as straight, smooth, and taut as possible,
minimizing the number of 90° bends and loops,
which can reduce airflow.
• Fasten the ducting securely to prevent sagging.
• Do not allow ducting to be flattened or kinked.
• Trim excess ducting lengths following installation.
• Insulate ducting when it is located in high-heat areas.
• Ensure that ducting is properly protected against
damage when routed through open areas.
• Do not route ducting through an engine room or any
area where it may be exposed to dangerous vapors
or exhaust fumes.
If a transition box is used, the total area of supply air
ducts going out of the box should be at least equal
to the total area of the supply ducts going into the
box. Refer to “Minimum Duct and Grille Sizes per BTU
Capacity” on page 5 for minimum duct diameters.
