PENETRATING ROOF
To maintain a 1" clearance to pipe on a roof with a pitch, a rectangular
opening must be cut.
1. Determine center point where pipe will penetrate the roof.
2. Determine center point of the roof. Pitch is the distance the roof
drops over a given span, usually 12". A 6/12 pitch means that the
roof drops 6" for each 12" measure horizontally down from roof
rafters.
3. Use roof opening chart (Figure 15) to determine correct opening
length and flashing required.
4. Remove shingles around opening measured. Cut out this section.
5. Add next sections of pipe until end penetrates roof line. Check to see
that proper clearances are maintained. Extend chimney by adding
sections of double wall pipe until pipe is minimum of 30" above
highest point of roof cutout. Termination and chimney must extend
a minimum of 36" above highest point where it passes through
roof.

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 16). 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.

Storm Collar Installation (SC1)
Place storm collar over pipe and slide down until it is snug against
open edge of flashing (see Figure 17). Use SC1 for all round termina-
tions. 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
with termination. Terminations approved for this fireplace are RT-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 termination only.
Figure 18 shows an RLT-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 and
RLTT-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.
