Otherwise, install
firestop below the framed hole. The firestop should be
installed with no less than three nails per side.

2. Assemble the desired lengths of pipe and elbows nec-
essary to reach from the burner system flue up through
the firestop. Be sure pipe and elbow connections are
fully twist-locked.

3. Cut a hole in the roof using the locating hole as a center
point. (Cover any exposed open vent pipes before
cutting hole in roof). The 9

hole must be measured on the horizontal. Actual length
may be larger depending on the pitch of the roof. There
must be a 1" minimum clearance from the vent pipe to
combustible materials. Frame the opening as shown in
on
Page 16, Figure 15.
4. Connect a section of pipe and extend up through the
hole.
NOTE:
If an offset is needed to avoid obstructions, you
must support the vent pipe every three (3) feet. Use wall
straps for this purpose.
Page 18, Figure 22.
Whenever
possible, use 45° elbows instead of 90° elbows. The 45°
elbow offers less restriction to the flow of the flue gases
and intake air.
5. Place the flashing over the pipe section(s) extending
through the roof. Secure the base of the flashing to
the roof and framing with roofing nails. Be sure roofing
material overlaps the top edge of the flashing as shown
in
Page 18, Figure 22
. There must be a 1" clearance
from the vent pipe to combustible materials.
6. Continue to add pipe sections until the height of the vent
cap meets the minimum building code requirements.
