FLASHING INSTALLATION (V6F-8DM
OR V12F-8DM)
Determine the flashing to be used with the 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 nail-
ing through shingles (see Figure 13). DO NOT
NAIL THROUGH FLASHING CONE.
Installing Flashing on a Metal Roof
When installing the flashing on a metal roof,
it is required that putty tape be used between
the flashing and the roof. The flashing must be
secured to the roof using #8 x 3/4" screws and
then sealed with roof coating to prevent leakage
through the screw holes. A roof coating must
also be applied around the perimeter of the
flashing to provide a proper seal.

Storm Collar Installation (SC1 or SC2)
Place storm collar over pipe and slide down
until it is snug against the open edge of the
flashing (see Figure 14). Use SC1 for all round
terminations and SC2 for all terminations
with slip sections. Apply waterproof caulk
around the perimeter of the collar to provide
a proper seal.

The fireplace system must be terminated with

approved for this fireplace are the 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 15
shows an RTL-8DM round top termination.
CAUTION: Do not seal open-
ings on the rooftop flashing. Fol-
