22' Install Manual 10-W1 Vent Installation Stage 2
Included in the Growing Dome
®
kit for completing the vent installation (Stage 2) are the following:
2
– 6’ nylon cord (restrainer cords for top vents)
2
– 3-1/2” nylon cords (restrainer cords for bottom vents)
4
– eyebolts, fender washers, and nuts
6
– screw eyes (2 per top vent / 1 per bottom vent)
1-
3/4” bronze star drive screws (to attach
hinges and
crossbars)
Crossbars
– 2 @ 30” (for top vents) & 2 @ 36” (for bottom vents)
Bayliss solar powered openers (for “A” top vents)
Univent solar powered
openers (for “E” bottom vents)
Vent gaskets (cut to length)
Hex head screws to attach vent gaskets
The vent gaskets are used to create a weatherproofing seal when the vents close. It is easier to install the
gaskets before installing the crossbar.
See “Vent Gasket Installation” Video 10-V1. The vent gaskets are cut to
length and may come as one piece or two pieces that are butted up to each other
. Butting the gaskets doesn’t
lead to any problems but always place the shorter piece towards the hinge end as the gasket is harder to screw in
closer to the point of the vent.
The hinged side of the vent does not need gaskets. Place the length of gasket in position with the rubber edge
towards the vent itself and press up against the vent to make a tight seal. Mark the edge of the metal of the
gasket with a pencil on the strut before you install it. You will need to open the vent in order to install the gasket
and the pencil line will show exactly where you want the gasket to be located. Screw the gasket firmly in position
with a
3/4” hex head screw in every hole. They are provided with the kit. (A new 1/4” magnetic hex bit will make
the process much easier.)
The vent crossbar is installed parallel to the strut that the vent is hinged on and in such a manner that the holes,
which are drilled diagonally on the ends, follow the line of the struts. It is best to take measurements to ensure
that the crossbar is indeed parallel to that strut. Use 1-
3/4” bronze star drive screws through these holes to attach
the crossbar. The two top vents use the 30” crossbars and the two bottom vents use the 36” crossbars. The holes
in the middle of the crossbars are pre-drilled for the specific openers which come with your dome kit.
Be aware that once the openers are installed to the crossbars and the vents themselves, they will be trying to
force the vents open as the inside of the dome heats (that’s their purpose). You will need to make sure you untie
the restraining cords so that the vents can open. After the openers are attached, you will need to re-tie the
restraining cords per the instructions
in “The Restraining Cord Stage 2” section at the end of this Step.
First, fix the Univent opener bracket onto the crossbar.
See “Univent Opener Installation” Video 10-V2. The
opener bracket is screwed through the two holes in the crossbar, as shown in the video, using the short screws
provided in the kit, screwing through the holes in the crossbar and into a backing plate provided in the opener kit.
Attach the arms of the opener to the bracket by squeezing the arms together and inserting the prongs into the
slots of the bracket. Place the other end of the actuating arm against the glazing making sure the pressure of the
