- Locate the assembly and unpack from the crate.
- If the MUA risers are to be field cut, cut the risers in as desired.
(Note: The manufacturer installs a 2" flange for a MUA riser.
This flange is intended to slip inside a MUA boot that is supplied
by the installer.)
- Locate the wall and ceiling joists that will support the assembly.
- Install the threaded rod and angle that will be used to hang the
assembly from the ceiling joists.
- Move the assembly into position as indicated by the markings on the
product. Note the location of the 78" A.F.F. critical hanging
height marking. This point should be level with the bottom back edge
of the hood when it is hung later.
- Install the threaded rod into the hood hanging angles and use
heavy-duty nuts to secure the connection.
- Caulk the seams between the wall and the drop down plenum assembly.
