PENETRATING ROOF
To maintain a 1" clearance to the pipe on a roof with a pitch, a rect-
angular opening must be cut.
1. Determine center point through which pipe will penetrate roof.
2. Determine center point of 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" one measure horizontally down from the
roof rafters.
3. Use roof opening chart (Figure 12) to determine the correct open-
ing length and flashing required.
4. Remove the shingles around opening measured. Cut out this
section.
5. Add next sections of pipe until end penetrates roof line. Check to
see that the proper clearances are maintained. Extend chimney by
adding sections of double wall pipe until pipe is minimum of 30"
above the highest point of the roof cutout. Termination and chimney
must extend a minimum of 36" above the highest point where it
passes through the roof.
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 nailing through shingles (see Figure 13). 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 the flashing and 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 screw holes. A roof coating must also be applied around
perimeter of 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.
Terminations/Spark Arrestor
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. The termination approved for this fire-
place are the 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 15, page 11 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. The RTT-8DM
and RLTT-8DM are approved for flashing installations. When needed,
these adjustable terminations may be used in combination with the
pipe assembly to achieve the correct chimney height.
Note:
In the rare instance there is a problem with the side driven rain
or wind or the chimney is not drafting properly, an ADS-8DM (Anti-
Draft Shield) can be used with round terminations.
