STORM COLLAR INSTALLATION (SC-10)
Place storm collar over pipe and slide down until it is snug against
the open edge of the flashing (see Figures 24 and 25). Apply water-
proof caulking to all seams and notches around storm and also at
base around shingles.
TERMINATIONS
Standard Installation
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.
Terminations approved for this fireplace are RLT-12D, which can be
used for flashing or chase and STL-12D for chase style termination
only. Figure 26, shows an RLT-12D round top termination.
Follow installation instructions provided with termination being used.
CAUTION: Do not seal openings on the rooftop
flashing. Follow the installation instructions provided
with the termination being used.

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. Terminations must be separated a
minimum of 24" center to center and stacked at a minimum vertical
height difference of 18" (see Figure 27).
Note:
If a decorative shroud is to be installed, contact the manufac-
turer for specifications.
