19. With the Z-bracket (77) attached, lift the support arm
(74) out of the bracket and remove the vent frame from
the greenhouse to install the polycarbonate panel.
NOTE: The polycarbonate panels for the vents can
be installed with the vent frame attached to the
greenhouse roof if desired. This procedure installs the
polycarbonate panels with the assembled roof vents
removed for easier accessibility.
20. Repeat the steps to assemble and install all remaining
vent frames. Consult the Quick Start section.
