CHASE INSTALLATIONS
Instructions for chase installations are included with the chase style
termination chosen. In a multiple chase installation, be sure to provide
adequate distance between terminations to prevent smoke spillage
from one termination to another. We suggest that terminations be
separated at least 24", center to center and stacked at a vertical height
difference of 18" (see Figure 21).
Note: If a decorative shroud is to be installed, contact the manufac-
turer for specifications.
