Discharge Duct Installation
If an interior furnace or air handler will be connected to the
supply duct system, the supply duct connector should be
equipped with a damper. See Figure 8.
If no interior furnace or air handler will be connected to the
ductwork, the duct connector may be a 12”diameter round duct.
See Figure 9.
When locating the duct connector, check carefully for floor
joists, axles, wheels and frame members that could interfere
with the installation of the duct connector or the running of the
duct. Ideally, the duct connector should be located in the bottom
of the main duct, forward of center of the manufactured home.
Do not install duct connector under a register.This will help to
eliminate the transmission of sound into the home.
To locate the center of the duct, first cut a 6” hole in the
fiberboard below the duct at the desired location.After locating
the duct center, increase the hole in the fiber board to
approximately the size of the duct connector.
