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.
Models Affected: F/S-3V-I, F/S-3V-II, F/S-AF-I AND F/S-AF-II
