CSS Heat Release

Valance

A valance may be desired to accentuate or hide the outlet. This is an optional decorative feature that covers up the CSS outlet gap. Minimum opening and valance dimensions must be followed to ensure safe heat dissipation. Combustible material is acceptable when constructing the valance. It is acceptable to wrap the valance around the three sides of a built out chase.

Side Discharge

Construct the framing in a way that provides two gaps, one on each side of the chase as shown in. Each gap should be a minimum of 21 inch (533mm) by 3 inch (76mm). It is essential that these dimensions are followed and not to deviated from them when using combustible materials inside the chase.

False Ceiling

If your ceiling dimension is greater than the minimum You may want the heat discharge lower on the wall. To do this a false ceiling is required to properly evacuate the heat from the chase.

Open Chase (built-out installations)

This could be considered the most discreet option 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 a Valance to work in conjunction with this option.
