TLCEK — Insulated 15- and 30-degree Elbow Kits

Assets/Details

  • The insulated elbow is used when offset is required.
  • Locking bands must be used on all elbows.
  • A maximum of 6 feet is allowable between offsets.
  • Elbow is fully insulated and can be used with the same 2-inch clearance as chimney lengths.
  • Elbow support must be used with all offset installations and will support 15 feet of chimney.
  • Elbows do not have twist-locking ridges, so they can be rotated to attain optimum positioning offset and allow chimney to return to correct vertical alignment prior to installing locking bands.
  • May not be used outdoors.
  • Elbow kits include: 2 elbows (Exception: 12” and 14” sizes include four 15° elbows assembled into two 30° elbows) 4 locking bands (Exception: 10”, 12” and 14” sizes include two locking bands) 1 elbow support All hardware
