Terminations with 16" slip pipe sections are
available. The RTT-8DM and RTTL-8DM are
approved for flashing installations. When
needed, these adjustable terminations may be
used in combination with the pipe assembly to
achieve the correct chimney height.
Note: In the rare instance there is a problem
with the side driven rain or wind or the chim-
ney is not drafting properly, an ADS-8DM
(Anti-Draft Shield) can be used with round
terminations.
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 16).
Note: If a decorative shroud is to be installed,
contact the manufacturer 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 high-
est point of the roof that is within a horizontal
distance of 10 feet (see Figure 17).

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.
