F/S Sleeve Location Update

We are updating our combination fire smoke damper location in the sleeve.

• Our new standard is that the damper will be set back 8” from the end of the sleeve.
• Standard sleeve length is 16”. (Wall depth up to 5”)
• Any additional sleeve length ordered will be added to the back side of the damper.
• Consult United Enertech for sleeve lengths for units with smoke detectors.
