Installation Instructions
Note: When installing each section, be sure to rig each piece
separately using the lifting lugs provided.
1. Mount roof curb to roof deck in accordance with local codes.
2. Install 3/16-inch thick x 1/2-inch wide, closed-cell neoprene gasket
on the top edge of the curb, adhesive side down (gasket provided).
Leave no gaps between gasket sections to ensure tight seal.
3. Place the bypass air plenum (BAP) onto the previously installed
gasket and secured roof curb. If a BAP is not provided for the unit,
skip to Step 5. Pre-drill pilot holes into the roof curb and attach
the BAP to the roof curb using the provided 5/16-inch self-tapping
screws. Screw fasteners are to be installed in all pre-punched curb
holes.
4. Install 3/16-inch thick x 1/2-inch wide, closed-cell neoprene gasket
on the top edge of BAP, adhesive side down (gasket provided).
Leave no gaps between gasket sections to ensure a tight seal.
5. Place the curb cap of the fan housing onto the gasket and BAP
(onto roof curb if BAP is not provided). Attach the curb cap
using the provided 5/16-inch self-tapping screws. If a BAP is not
provided, pilot holes must be drilled into the roof curb.
6. Install the final nozzle subassemblies as shown in the submittal
drawing. Align flange bolt holes and fasten sections using the 316
stainless steel bolts, washers, and lock washers provided.
7. Follow electrical connection and pre-start-up checks as listed on
page 3.
Duct Connection to Curb
The end of the customer supplied duct is secured between the roof curb's top edge and the curb cap of either
the Vektor-H or bypass air plenum. If an isolation damper is present in the roof curb, the duct is located between
