Nailing Flange Extension
1. Ensure that the two
long
mounting brackets are facing the bottom of the
termination. (See inset). This will provide more heat protection at the top of
the termination, where temperatures are highest.
2. Attach to the faceplate of the termination using four sheet metal screws.

Installing The Standoffs
To avoid elevated mantel temperatures, all
Vista 38 ST
Series gas fireplaces are
required to have the supplied standoffs installed.
The fireplace is supplied with two standoffs. Bend and install these standoffs
on top of the fireplace ensuring that the height of the standoff maintains a 6"
clearance.

Installing the standoffs.
Installing the Nailing Flange Extension
Once the fireplace is placed into the framed opening, the supplied nailing exten-
sion must placed along the top edge of the fireplace, and nailed in place to the
framing, as illustrated below. The supplied nailing extension must be placed
along the top edge of the fireplace and securely fastened in place to the lintel and
combustible wood framing.
Note:
The nailing flange extension can be substituted with a piece of
NON-
COMBUSTIBLE
material of the same size and thermal characteristics, i.e.; cement
board or equivalent.
