Initial Installation
QUALIFIED INSTALLERS ONLY
Combustible material may be brought up to any finishing edge
ONLY
if the Cool Surface System
(CSS) has been correctly activated allowing heat in the chase to be vented.
This system keeps the front
wall cool enough for any combustible materials. The supplied non-combustible board can still be used but is not
mandatory when the CSS is activated, combustible material may overlap in this situation.
If the CSS has NOT been activated (Traditional Install) you
MUST
use a non-combustible material
directly above the fireplace extending up the front wall 9” from the top finishing edge
, it is recom-
mended to use the supplied non-combustible board. Combustible material must NOT be brought up to the top
finishing edge. Also combustible material CANNOT overlap the non-combustible board on a traditional installation.

WARNING: IT IS ESSENTIAL THAT THE CHASE IS VENTED IN A MANNER THAT RELIEVES THE
ADDITIONAL HEAT ENTERING THE CHASE. ENSURE ONE OF THE AVAILABLE FRAMING OPTIONS
HAVE BEEN CONSTRUCTED IN ACCORDANCE WITH THIS MANUAL. FAILURE TO DO SO CAN
CREATE AN OVERHEATING SITUATION THAT COULD LEAD TO BUILDING FIRE.
Ensure your chase has been constructed in a
manner that vents the chase into the same
room. It is not permitted to vent the chase
into an adjoining room. The CSS bleeds heat
off the fireplace into the chase as opposed to
climbing up the front face. This dramatically
lowers the front wall temperatures allowing
the placement of delicate objects above
the fireplace. Review the guidelines in the
previous sections to ensure your install is in
accordance with the framing specifications.
Follow these instructions to active the CSS
feature. The non-combustible board included
with the fireplace is no longer required when
using CSS.

Figure 40: Inner Finishing Edge Dims
NOTE: These are exact dimension add tolerance when cutting finishing material to ensure fit
around the finishing edge. This is especially important when using the inner edge. The surround
will overlap the inner edge by 0.375” and hide the cut edge.
