STEP 8: INSTALLING AIR DISTRIBUTION COMPONENTS
All plenum duct and supply tubing runs as well as room
terminator locations must be in accordance with air
distribution system requirements listed in Section 1 of
this manual. Where taping of joints is required, UL181
approved tape is required.
Plenum Duct Installation
All tees, elbows and branch runs must be a minimum of 24"
from the fan coil unit or any other tee, elbow or branch run.
Keep all tees and elbows to a minimum to keep system
pressure drop on larger layouts to a minimum.
