1.
Fasten the roof support to the roof using the screws
provided.
FIGURE 13.
The roof support is optional. In this
case the venting is to be adequately supported using ei-
ther an alternate method suitable to the authority having
jurisdiction or the optional roof support.
2.
Stretch the 4" diameter aluminum flexible liner to the
required length. Slip the liner a minimum of 2" over the inner sleeve of the air terminal and
secure with 3 #8 screws. Seal using a heavy bead of the high temperature sealant.
3.
Repeat using 7" diameter aluminum flexible liner.
FIGURE 12.
4.
Thread the air terminal pipe assembly down through the roof. The air terminal must be
located vertically and plumb. Attach the air terminal assembly to the roof support, ensuring that
a minimum 16" of air terminal will penetrate the roof when fastened.
DO NOT CLAMP THE FLEXIBLE ALUMINUM LINER.
5.
Remove nails from the shingles, above and to the sides of the chimney. Place the flashing over the air terminal and
slide it underneath the sides and upper edge of the shingles. Ensure that the air terminal is properly centered within the
flashing, giving a 3/4" margin all around. Fasten to the roof. Do
not
nail through
the lower portion of the flashing. Make weather-tight by sealing with caulking.
Where possible, cover the sides and top edges of the flashing with roofing mate-
rial.
6.
Apply a heavy bead of weatherproof caulking 2 inches above the flashing.
Slide the storm collar around the air terminal and down to the caulking. Tighten to
ensure that a weather-tight seal between the air terminal and the collar is achieved.
Attach the other storm collar centered between the air intake and the air exhaust
slots onto the air terminal. Tighten securely.
FIGURE 14.
Attach the vertical rain
cap.
Spacers are attached to the 4" inner flex liner at predetermined intervals to
maintain a 1-1/4" air gap to the 7" outer liner. These spacers must not be removed.
7.
If more liner needs to be used to reach the fireplace, follow the same procedure as found in
EXTENDED HORIZON-
TAL AND CORNER AIR TERMINAL INSTALLATION
. The vent system must be supported approximately every 3 feet for
both vertical and horizontal runs. Use Wolf Steel support ring assembly
GA-GD-010.370
or equivalent noncombustible
strapping to maintain a clearance to combustibles of 1".
