Plenum and Curb to Structural Steel

An additional side (or access) panel may need to be removed in order to gain access to the inside of the plenum assembly. The bolts should be tightened in an even and consistent manner as to pull the two sections together and compress the gasketing.

After the plenum is assembled

Use all provided hardware to tighten and join the mating sections together. Any side panels removed to gain access to the interior of the plenum should be reattached. The assembled plenum has holes in the curb cap to fasten the plenum to the already installed roof curb.

The plenum is now ready to have gasketing placed in the mounting location between the plenum and the fan. After the gasketing has been attached the fans can be lifted and set into place.

materials. Consult an architect or structural engineer for proper means of attachment.

Place 1/2 inch thick x 1/2 inch wide silicone gasket around the perimeter of top edge of curb, adhesive side down (gasket provided in Vektor-CD hardware kit).

To align holes properly, the plenum needs to be centered on the curb.

When holes are provided in the curb, install 316 stainless steel screws (provided) in all holes. Use anti- seize gel (provided) to prevent galling / welding of all stainless steel fasteners.

When holes are not provided in the curb (non Greenheck curb): Drill 0.28 in. diameter holes in curb using bypass air plenum holes as a template. Install 5/16 in. self-tapping screws (provided) in all the holes.
