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 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.

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 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 shows an RTL-8DM round top termination.

CAUTION: Do not seal open- ings on the rooftop flashing. Fol- low the installation instructions provided with the termination being used.

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, contact manufacturer for specifications.
