TERMINATIONS / SPARK ARRESTOR
The fireplace system must be terminated with the listed round
top or chase terminations. In any case, refer to the installation
instructions supplied with the termination. The terminations
approved for this fireplace are the RT-8DM and RTL-8DM
that can be used for flashing or chase and ET-8DM, ETO-
8DM, ETL-8DM and ETLO-8DM for chase style termination
only. Figure 15 shows an RTL-8DM round top termination.

TERMINATION
CAUTION: Do not seal openings on the rooftop flashing.
Follow the installation instructions provided with the
termination being used.
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 chimney 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 inches,
center to center and stacked at vertical height difference of 18
inches (see figure 16).

MULTIPLE CHASE INSTALLATION
*NOTE: If a decorative shroud is to be installed, contact the
manufacturer for specifications.
10-FOOT RULE
All flue gas outlet of chimney termination 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 THE FIREPLACE
Combustible materials, such as wallboard, gypsum board,
sheet rock, drywall, plywood, etc. may make direct contact
with sides and top periphery of the fireplace face. It is
important that combustible materials do not overlap the face
itself. Brick, glass, tile or other non-combustible materials
may overlap the front face provided they do not obstruct
essential openings like louvered slots or any other opening.
When overlapping with a non-combustible facing material,
use only non-combustible mortar or adhesive.
