  • Wood Fireplaces and Stoves: venting must be terminated to the outdoors vertically.
  • Pellet Stoves: most are vented horizontally, directly through the wall to the outdoors.
  • Fireplace Inserts: most are vented vertically through the roof, via the existing chimney.
  • Electric Fireplaces: no venting is required.
