Pre-Installation Requirements

1. Verify that the roof structure can adequately support the combined weight of the unit and curb

assembly.

2. Ensure that the selected installation location provides sufficient service and operational

clearances.

3. Remove any twist within the curb due to roof supports and square the curb.

4. Level the curb.

5. Secure the curb to the roof support members.

6. Install 2-inch thick boards or rigid insulation around the curb.

7. Install cant strips around the curb.

8. Bring field supplied roofing felt up to the top of the curb nailing strips. Nail felt into place.

9. Install field supplied flashing under the lip of the curb flanges and over the felt.

10. Apply sealant to the four corners. Caulk all joints between the curb and the roof. Attach the

gasket material to the curb’s top flanges (entire perimeter) and to the supply and return air duct

opening panel flanges

Suggested Tools

• Two chain come-alongs. These have the pulling power to bring the shipping splits together, one

on each side of the unit. Cable come-alongs are not strong enough and normally will fail. The

chain versions work well.

• Two long drift pins to keep holes aligned as the sections come together.

• One half-inch or 3/4-inch electric impact gun. These are very effective to tighten the bolts at the

base once it’s close enough together to get the bolts in.

• Caulk guns.

• Standard battery impact gun or battery drill for installation of screw in joint strips, hubcaps, and

inlet or exhaust hoods.

• Nut setters for battery impact gun - 3/8-inch and 5/16-inch.

• Utility knives for cutting section-to-section gasket.

• A couple of large pry bars.

• Proper size sockets and wrenches to remove lifting lugs when in positions. Multiple size sockets.

Must have 15/16-inch and 1 1/16-inch sockets.
