LDVR Series Direct Vent Gas Fireplace
10007317
A hearth is not mandatory but is recommended for aes-
thetic purposes. We recommend a noncombustible hearth
which projects out 1” (305mm) or more from the front of
the fireplace.
Cold climate installation recommendation:
When installing this unit against a non-
insulated exterior wall or chase, it is
mandatory that the outer walls be insulated
to conform to applicable insulation codes.
Hearth
Noncombustible materials such as brick or tile may be
extended over the edges of the face of the fireplace. DO
NOT cover any vent or grille panels.
If a Trim Kit is going to be installed on the fireplace, the
brick or tile will have to be installed flush with the edges
of the fireplace.

To mount the appliance:
1. Choose the location.
. This unit comes with four (4) flanges pre-mounted on
both sides of the fireplace to allow two different drywall

while flange “B” is for 5/8” drywall.
3. Bend the desired flanges out 90° on both sides of the
fireplace. Slide the fireplace into the framed opening
until the flanges contact the front surfaces of the fram-
ing. Level the unit and secure it firmly in place.
