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 16).
Note:
If a decorative shroud is to be installed, contact the manufac
-
turer for specifications.
10 FOOT RULE
All flue gas outlet chimney terminations must extend a minimum of
3 feet in height above the highest point where it passes through the
roof and must be at least 2 feet above the highest point of the roof
that is within a horizontal distance of 10 feet (see Figure 17).
FINISHING FIREPLACE
Combustible materials, such as wallboard, sheet rock, drywall, plywood,
etc. may make direct contact with sides and top around the fireplace
face. It is important that combustible materials do not overlap the face
itself. Brick, glass, tile or other noncombustible materials may overlap
the front face provided they do not obstruct essential openings like
louvered slots or any other opening. When overlapping with a noncom-
bustible facing material, use only noncombustible mortar or adhesive.
