CHASE INSTALLATIONS
Instructions for chase installations are included with chase style ter-
mination 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 19).
Note:
If a decorative shroud is to be installed, contact manufacturer
for specifications.

10 FOOT RULE
All flue gas outlet chimney terminations must extend a minimum of
3 feet in height above highest point where it passes through roof and
must be at least 2 feet above highest 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 fireplace face. It is important that combustible materials
do not overlap face itself. Brick, glass, tile or other noncombustible
materials may overlap front face provided they do not obstruct es-
sential openings such as louvered slots. When overlapping with a
noncombustible facing material, use only noncombustible mortar
or adhesive.
Storm Collar Installation (SC1)
Place storm collar over pipe and slide down until it is snug against
open edge of flashing (see Figure 17). Use SC1 for all round termina
-
tions. Apply waterproof caulk around perimeter of collar to provide
a proper seal.

Terminations/Spark Arrestor
Fireplace system must be terminated with listed round top or chase
terminations. In any case, refer to installation instructions supplied
with termination. Terminations approved for this fireplace are RT-
8DM, RTL -8DM and RLT-8DM that can be used for flashing or chase
and ET-8DM, ETO-8DM, ETL-8DM and ETLO-8DM for chase style ter
-
mination only. Figure 18 shows an RTL-8DM round top 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. RTT-8DM,
RTTL-8DM and RLTT-8DM are approved for flashing installations.
When needed, these adjustable terminations may be used in combi
-
nation with pipe assembly to achieve correct chimney height.
Note:
In the rare instance there is a problem with side driven rain or
wind or chimney is not drafting properly, an ADS-8DM (Anti-Draft
Shield) can be used with round terminations.
