FLASHING INSTALLATION (V6F-8DM OR V12F-8DM)
Determine flashing to be used with roof opening chart. Slide flashing
over pipe until base is flat against roof. Replace as many shingles as
needed to cover exposed area and flashing base. Secure in position
by nailing through shingles (see Figure 15). DO NOT NAIL THROUGH
FLASHING CONE.
Installing Flashing on a Metal Roof
When installing flashing on a metal roof, it is required that putty tape
be used between flashing and roof. Flashing must be secured to roof
using #8 x 3/4" screws and then sealed with roof coating to prevent
leakage through screw holes. A roof coating must also be applied
around perimeter of flashing 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 17 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 combina-
tion 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.
