replaces are required to have the supplied standoffs installed.
The replace is supplied with two standoffs. Bend and install these
standoffs on top of the replace ensuring that the height of the standoff
maintains a 6" clearance.

Installing the Nailing Flange Extension
Once the replace is placed into the rough framed opening, the supplied
Nailing Flange Extension (Part No. H42074) must be fasten securely
into place, with nails or wood screws. as shown in Figure 8.
The Supplied nailing extension must be placed along the top edge of the
replace and securely fastened in place to the non combustible header
and combustible wood framing.

NON-Combustible material of the same size and thermal characteristics,
ie: cement board or equivalent. This is recommended in applications
where the facing materials will not adhere to the metal nailing ange.
Note: Clearance from top of replace to a combustible ceiling within
the replace enclosure.
