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 high-
est point of the roof that is within a horizontal
distance of 10 feet (see Figure 20).
FINISHING FIREPLACE
Combustible materials, such as wallboard,
gypsum board, 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 noncombustible facing
material, use only noncombustible mortar or
adhesive.

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 dif-
ference of 18" (see Figure 19).
Note: If a decorative shroud is to be installed,
contact the manufacturer for specifications.
