Installation
Requirements and
Recommendations
that Apply to ALL
Reznor ® Roof Curbs
• Before installation, verify (1) that the curb ordered is the appropriate one for the
unit and (2) that the curb supplied is the correct size.
• Position the curb depending on roof structure and so that the air inlet is not facing
into the prevailing wind. Depending on the weight and the roof structure, tread
material may be required under the rails. Curb and equipment must be level.
• If installing more than one system, it is recommended to minimize structural span
deflection to discourage sound transmission.
• Mounting hardware and flashing must be field supplied.
• Assembly and installation of the curb are the responsibility of the installer.
