Locate the ERV Roof Curb

— Prior to locating the ERV roof

curb consider the structural support required for the rooftop

system, the duct drop location in relation to the joists, and the

100 equivalent foot duct length limitation between the ERV

and RTU. Allow sufficient space for service, clearance, and lo-

cations of vents or other sources of air. Refer to Fig. 2 and 3 for

ERV clearance requirements. Refer to the rooftop installation

instructions for more information regarding location and instal-

lation considerations for the RTU curb.

Assemble the ERV Roof Curb

— Connect the curb side and

the curb end. Insert the tabs on the curb end into the slots on the

curb sides. See Fig. 6. Press firmly until the pieces lock into

place. It may be necessary to exert additional force on top of

the curb to lock the pieces in place. Ensure the curb pieces are

locked together prior to proceeding further. Repeat for other

corners of the roof curb.

NOTE: If lifting or moving the roof curb assembly, hammer

the tabs over 90 degrees.

Prepare Roof Curb Location

— Cut a hole in the roof for duct

openings. See Fig. 7 for duct opening dimensions. Frame the

opening to provide adequate structural support.

Set the ERV Roof Curb

— Fit the roof curb assembly by mea-

suring across the corners of the curb to ensure a square fit. Set

the roof curb over the roof opening. Level the curb by placing

shims under the bottom flange of the curb. Secure the curb in

place by welding or fastening the curb to the roof.

NOTES:

1. Clearance above cabinet is 24 inches.

2. All dimensions shown in inches.
