Chateau™ Direct Vent Gas Fireplace
20011957
A hearth is not mandatory but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth which projects out 12” (305 mm) or more from
the front of the fireplace. The hearth cannot exceed 1¹⁄₂”
(38 mm) in height from bottom of fireplace for ease of
door accessibility. (Fig. 4)
Cold climate installation recommendation:
When installing this unit against a non-
insulated exterior wall or chase, it is
mandatory the outer walls be insulated to
conform to applicable insulation codes.
Hearth
Framing and Finishing
1. Choose the unit location.
2. The unit is shipped with four (4) nailing flanges
mounted near the front corners on the side with the
valve box assembly . (Fig. 4)
3. Frame the fireplace with a header across the top of
the standoff. (Fig. 5) It is very important to allow for
the finished wall face along with marble, tiles or any
other noncombustible face finish material desired
when setting the depth of the framing.
4. Attach the fireplace nailing flanges to the frame as
shown in Figure 4.

5. The gas components are located in the valve box as-
sembly attached to the side of the unit.
6. The U-channel located on the top of the unit as well
as the nailing flanges on the sides that were men-
tioned in Step 1, are designed to accommodate non-
combustible board (recommended Dura-Rock). They
are positioned 1” (25mm) back from the face of the
unit. NOTE: The U-channel depth can be adjusted
by loosening the hex nut inside the channel.
If marble, tile or any other noncombustible decora-
tive face finish material is desired, a 3” (76mm) wide
noncombustible board (recommended Dura-Rock)
is to be nailed to the nailing flanges on both sides
of the unit. Also, 12” (305mm) of noncombustible
board is to be nailed to the front face of the U-chan-
nel and the top framing member above the standoff.
Combustible material can then be brought to the
outside edges of the noncombustible board installed
earlier. Any noncombustible decorative face finish
could be brought to the sides and top of the unit and
can cover the framing and sheet rock. If a decora-
tive facing is not desired, then the noncombustible
boards must be double thickness and brought flush
with the face of the unit.
Final Finishing
Noncombustible materials such as brick or tile may be
brought to the edges of the face of the appliance.
