FIGURE 1 - Vent Kit

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

overlaps.

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.

ROPE / CABLE BRACKET

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.
