The Q1LI is supplied with two sets of standoffs that serve as a framing guide and must be used when the
unit is being installed as a replace. The front set of standoffs mount to sides of the unit (see Figure 27)

and can be adjusted as needed to
account for the thickness of the wall
material. The rear standoffs attach
to the back corners of the unit and
are not adjustable. Combustible
material can touch the standoffs
but must not encroach past them.
If the Q1LI is being installed into a
pre-existing masonary replace it is
not necessary to use the standoffs.
Installation of the standoffs will
require a T20 screwdriver. Remove the
installed screws in the noted locations,
place the standoff over the holes, and
re-install the screws.
