2. Assemble desired lengths of pipe and
elbows necessary to reach from fireplace
flue up through firestop. Be sure all pipe
and elbow connections are fully twist-
locked (see Figure 8, page 12).
3. Cut a hole in the roof using locating hole
as a center point. (Cover any exposed
open vent pipes before cutting hole in
roof.) The 11
1
measured on the horizontal; actual length
may be larger depending on pitch of roof.
There must be a 1" clearance from vent
pipe to combustible materials. Frame
opening as shown in Figure 9 page 12.
4. Connect a section of pipe and extend up
through hole.
Note: If an offset is needed to avoid
obstructions, you must support vent pipe
every 3 feet. Use wall straps for this pur-
pose (see Figure 14, page 15). Whenever
possible, use 45° elbows instead of 90°
elbows. The 45° elbow offers less restric-
tion to the flow of flue gases.
5. Place flashing over pipe section(s) ex-
tending through roof. Secure base of
flashing to roof and framing with roofing
nails. Be sure roofing material overlaps
top edge of flashing as shown in Figure
16. There must be a 1" clearance from
vent pipe to combustible materials.
6. Continue to add pipe sections until height
of vent cap meets the minimum building
code requirements described in Figure 7
on page 10.
Note: You must increase vent height for
steep roof pitches. Nearby trees, adjoining
rooflines, steep pitched roofs and other
similar factors may cause poor draft or
down-drafting in high winds. Increasing
vent height may solve this problem.
7. Twist-lock vent cap onto last section of
vent pipe.
Note: If vent pipe passes through any occupied
areas above first floor, including storage spaces
and closets, you must enclose pipe. You may
frame and sheetrock enclosure with standard
construction material. Make sure and meet the
minimum allowable clearances to combustibles.
Do not fill any required air spaces with insulation.
