The purpose of this optional Cool Surface System, or CSS, is to naturally re-direct the convective heat from
the replace. Using this CSS lowers the temperatures of the front wall for installations where a TV, artwork etc.

is desired directly above the replace.
The outlet of the CSS can be raised
higher up the front wall, within 4” of the
room’s ceiling. The CSS must be vented
directly into room where the appliance
is installed. If using the maximum facing
material thickness you will not be able to
install a surround. A maximum total of 1”
facing material (1/2” on top of cool wall
layer) is allowed if you are installing a
surround.
Note: You can install the Cool Surface
System without the Combustible Facing
Kit. Doing so requires a non combustible
facing material (see Owner’s Manual for
replace installation instructions).
Note: Dual Convection Fan Kit
(50-3212) may not be used in
conjunction with CSS.
Prior to installation of the CSS make
sure the desired location is large
enough to comply with the combustible
clearances of both the CSS and the
replace (see Owner’s Manual for
replace installation instructions). Refer
to the Framing and ClearanCes section of
this manual for the required installation
dimensions of the CSS.
Please refer to Figure 1 and Figure 2 to
ensure that all CSS parts are accounted
for and have not been damaged.

The CSS has been designed to allow for
installations where a vertical run of vent
is required without having to jog the
vent pipe around the CSS. The horizontal
vent shield supplied with the replace is
not required (see Owner’s Manual) when
vertically venting and the vent pipe can
simply be run straight up through the cut
out in the CSS.

Shown below are the minimun framing requirements and clearences for the HDK with recess framed above
the replace. Figure 11 shows the miniumun framing requirements for a 30” tall recess. The recess height
is adjustable as long as all minimun dimensions are met.
*IMPORTANT NOTE* - The optional Combustible Facing Kit CANNOT BE USED when a recess is
framed above the replace and non-combustible facing material must be used as outlined in the replaces
Owner’s Manual. If using a mantle, revised clearances CANNOT BE USED and mantle clearances must be
followed as outlined in the replace’s Owner’s Manual.
