  2. Intake Section & Throat
  3. Intake Doors
  4. Vent Cap
  5. Sprinkler
  6. Disinfecting & Flushing System
  7. Discharge Door
  8. Heat Sensor
  9. Pneumatic Doors
  10. NFPA

Floor Frame & Padding

  • Minimum 2” of bearing surface supporting each leg.
  • Opening can be square or round.
  • Rough opening should be 8” wider than the diameter of the chute.

Minimum of two inch bearing

Intake Section & Throat

  • 16 Gauge Aluminized Steel with slip joints (allow slight variations in height.)
  • One piece integral throat section (not added in the field).

Fully welded factory throat

Intake Doors

  • Stainless steel, self-closing, self-latching, with protected closer
  • Piano style hinge with deflector flap.
  • UL labeled doors (rated 1.5 hours with max temp rise 250 degrees in 30 minutes)

 

Vent Cap

  • Purpose of a vent is to dissipate odors and hot gases, smoke and flames in event of fire within the chute.
  • NFPA 82 code requires a full diameter vent penetrating and extending 3’ above the roof.

Sprinklers

PER NFPA 82

  • Above the top intake
  • Every alternate floor down to, and including the first floor above discharge
  • Sprinkler heads fuse at 165 degrees F to open up and flood the chute

OTHER

  • Sprinkler heads are installed in top corner of intake throat, with protective guard.
  • The automatic sprinkler heads furnished with the chute should be installed and piped in accordance with NFPA standards (by others).

Disinfecting & Flushing System

Disinfecting & sanitizing unit (D&S) flushing head & access door

  • A flushing spray head at top of each chute
  • Lockable access door above top intake
  • Manual shutoff valve – (installation & connection by others)
