Option 2: Open Chase (built-out installations) - This could be considered the most discreet option
when considering the CSS. The chase must be constructed in a way that stops short of the ceiling, leaving
it totally vented above. Minimum framing dimensions must be followed when constructing this option and
not to deviated from them when using combustible materials. Consider
Option 3: Valance to work in
conjunction with this option.

Optional: False Ceiling - If your ceiling dimension is greater than the minimum (Figure 37) You may want
the CSS Air discharge lower on the wall. To do this a false ceiling is required to properly evacuate the heat
from the chase. (See Figure 38).
