DESCRIPTION
The Generation Structures Vent Kit includes a vent frame,
vent door, and screw hardware necessary to install the
vent kit.
The standard vent kit sizes are 44” W x 8” H, 46” W x 7”
H, and 56” W x 10” H. Refer to Table A for Rough
Opening sizes.
NOTE: The vent hood, vent duct, and insulation barrier
kits are sold separately and not included with
this kit.
When the vent kit is received, check for shipping damage
or missing parts.
Important Installation Tip
The vent layout may permit the knee-brace corner tin to
have a repetitive cut-out pattern for several sheets. If
so, it may be advantageous to the installer to mark the
rough opening by drilling through a specific quantity of
tin while it is still in a stack. This can be accomplished
by marking the four corners of the rough opening cut-out
area and drilling through the stack of tin using a small
diameter drill bit. Single sheets of tin could then be
placed on saw horses and the rough opening cut before
screwing the metal onto the structure.
Tools Required
Drill Safety Glasses
¼” Drill Bit for starter holes. Automated Tin Nibblers
Screw Bits / Hex Head Bits
DANGER
Failure To Follow These Instructions May Result in
Injury!
1. Use Caution When Handling Sharp Metal.
2. Always Wear Safety Glasses When Drilling,
Fastening, Or Cutting Metal.

INSIDE TIN INSTALLATION
NOTE: The interior corner tin should be installed before
the interior ceiling and interior sidewall tin to
allow proper fit and placement of the vent kit.
1. Place a center mark on the knee brace and the
sheet of tin which will be placed in the corner. Install
the plastic sheeting (vapor barrier) and corner tin for
the entire length of the building. Ensure the corner
tin is consistently placed in the center of the knee
brace throughout the house. Refer to Figure 2.
NOTE: If the structure will have a flat-wall on the fan
end of the building, the flat-wall to corner-tin
transition point should be used for starting the
corner tin flush with the column. Refer to the
installation prints to determine if the fan end of
the building has flat walls and pour locations.
2. Proceed to install the interior ceiling tin, interior
sidewall tin, and plastic sheeting (vapor barrier).

Failure to install the metal straight will result
in gaps and unwanted air leaks where the tin

CUT ROUGH OPENING
3. Ensure the vent placement is accurate to the
drawings.
4. Refer to Table A and determine the correct rough
opening size for the required vent kit, determine the
correct rough opening location, and cut a
rectangular hole in the tin.
NOTE: With the corner tin centered on the knee brace,
the flat area of the tin will be the cut-out area.
Always cut the rough opening from the center
section of the tin. Refer to Figure 3.

INSULATION BARRIER INSTALLATION
(Optional)
NOTE: If vent duct will be installed, do not install the
optional Insulation Barriers and skip Steps 5 & 6.
5. Bend the two Insulation Barriers as shown in
Figure 4. The flange should always point outward.
6. Insert the two Insulation Barriers (placed in opposite
directions) into the cut-out opening with the barrier
flange overlapping the edge of the cut-out opening.
While keeping the barriers pressed to the cut-out
opening, install #8 x ½” Lap Tek screws through the
barrier overlapping ends. Refer to Figure 5.

VENT FRAME INSTALLATION
7. Center the vent frame over the rough opening and
attach the vent frame to the corner tin using three #8
x ½” Lap Tek screws along each side and seven
screws along the bottom (Door hinge side). Six
screws can also be installed along the top of the
Vent Frame although do not install the three center
screws at this time. Do Not Over Torque The
Screws. Refer to Figure 6.
NOTE: Once the vent frame is installed, the tin overlap
area may need to be pulled to the column using
Lap-tek or stitch screws.
PULLEY BRACKET INSTALLATION
8. Observe the pulley bracket orientation as shown in
Figure 7 and place the pulley bracket over the three
predrilled holes in the vent frame mounting flange
and attach using three #8 x ½” Lap Tek screws. Do
Not Over-Torque The Screws.
9. Bend the pulley bracket as shown in Figure 8 and
align the pulley bracket holes over the three
predrilled holes in the vent frame. Attach using
three #8 x ½” Lap Tek screws. Do Not Over-Torque
The Screws. Refer to Figure 9.

INSTALLATION
10. The Rope / Cable Attachment Bracket is flat and
preattached on one end for shipment. Refer to
Figure 10. Bend the bracket as shown in Figure 11
and align the bracket holes over the two predrilled
holes in the vent door. Attach using two pop-rivets.
11. When the rope or cable source is located to the right
of the vent door, install the pulley into the left slot
OR with a left source, install the pulley into the right
slot. Attach the rope or cable to the Cable Bracket,
feed through the pulley, and insert the pulley into the
appropriate bracket slot. Refer to Figures 12 and
13.

VENT DUCT ASSEMBLY (Optional)
The vent duct has two sheet metal parts. The duct top has two perforated areas which must be bent to form the side
panels. The bottom is preformed and no additional bending is required except for assembly purposes.
1. Bend the duct top/side part as shown in Figure 14 to
form the sides. The flanges should turn outward as
shown.
2. The bottom duct assembly tabs should be inserted
through the slots in the sides and bent in opposite
directions as shown in Figure 15.
3. Bend the duct ridge tabs outward at the four corners
as shown in Figure 16.

VENT DUCT INSTALLATION
(Optional)
NOTE: The vent duct is sold separately and not
included with this kit. The vent duct is
necessary only if outside-air ventilation is
required instead of attic-air ventilation.
1. Assemble the vent duct as described in Section I,
Vent Duct Assembly.
2. Insert the vent duct between the column and
intermediate post and place the duct so that the vent
duct notches fit on the corner tin ridges as shown in
Figure 17.
3. Screw the vent duct side flanges to the columns with
#8 x ½” pan-head screws. Refer to Figure 18.
4. Cut the bird wire to the appropriate size to fit over
the top, bottom, and side duct flanges. Secure the
bird wire to the column with two #8 x ½” pan-head
screws. Pull the wire tight and attach opposite side
with two #8 x ½” pan-head screws.

VENT HOOD ASSEMBLY &
INSTALLATION (Optional)
The vent hood has three parts. The top is preformed
and no additional bending is required. The two side
parts have perforated areas which must be bent 90
degrees to form the side flange.
NOTE: The vent hood is sold separately and not
included with this kit.
1. Form the two end parts by hand bending the
perforated area 90 degrees to form the flanges as
shown in Figure 19.
NOTE: Ensure one side part is bent in one direction and
the other side part is bent in the opposite
direction.
2. Insert the end tabs through the cover slots and bend
the tabs inward.
3. Place the vent hood over the bird wire and vent duct
flanges and secure the vent hood flanges to the
column, intermediate post, and vent duct flanges
with #8 x ½” pan-head screws. Refer to Figure 20.
