Storm Collar Installation (SC1 or SC2)
Place storm collar over pipe and slide down
until it is snug against open edge of flashing
(see Figure 16). Use SC1 for all round ter
-
minations and SC2 for all terminations with
slip sections. 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

this fireplace are 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 17

Terminations with 16" slip pipe sections are
available. RTT-8DM and RTTL-8DM are
approved for flashing installations. When
needed, these adjustable terminations may
be used in combination 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.

CHASE INSTALLATIONS
Instructions for chase installations are includ
-
ed with 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 difference of 18"
(see Figure 18).
Note: If a decorative shroud is to be installed,
