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. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
 
 

 
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). 
 
 
 
 
 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
*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.

Figure 17                 10-FOOT RULE 

CAUTION

: Do not seal openings on the rooftop flashing.

Follow the installation instructions provided with the
termination being used.
