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.
