TYPICAL DVS MID-V INSTALLATION WITH A-COIL
BRANCH DUCTWORK
After the floor and ceiling holes have all been located
and drilled, it’s time to install the 3” branch ducts. Run
the 3” duct parallel to the joists whenever possible as this
takes less space. The 3” duct should then be fastened to
the joist with strapping material. If the 3” duct is in an
unconditioned space, it must be insulated to local code
then all connections must be tapped to ensure a continuous
vapor seal. Do not damage the vapor barrier on the 3” duct.
If it is damaged, the holes must be taped with foil tape.
If possible run the 3” duct between the insulation and
the vapor barrier. Use of non-insulated ductwork can be
used in conditioned spaces.
