Clearance Requirements
There is no minimum clearance requirement between the wall opening and the sleeve exterior. However, to
facilitate installation, clearances between the wall opening and the damper sleeve are recommended. Although
there is no maximum allowable clearance, a minimum overlap of 1/2 in. (13mm) between the wall and the flange/
retaining angle must be maintained.
1. Single Flange Method
Damper/sleeve assemblies must be installed in wall openings using flanges and sheet metal screws as illustrated
and describe below. This method is only applicable to 11/2 hour rated damper; the 3 hour damper and dampers
larger than 36 in. x 36 in. (914mm x 914mm) will require a minimum of 11/2 in. x 11/2 in. (38mm x 38mm) legs.
• Flange on front (grille end) of sleeve must be a minimum of 16 ga. (1.6mm) steel and have a 5/8 in. minimum
flange leg. Using #10 sheet metal screws, screw from inside of sleeve through the rear portion of the studs (as
shown in Figure 1 & 2). Space screws a maximum of 6 in. (152mm) on center and a maximum of 2 in. (51mm)
from the corners (minimum of two screws per side). No retaining angles are required on the side of wall opposite
from the grille.
