Inside the house 7

  1. Stovepipe Also called connector pipe. It joins the stove to the chimney.
  2. Flue collar The venting starts here and runs from this point to the outdoors.
  3. Ceiling support box It carries the weight of the chimney pipe above it.
  4. Stovepipe adapter It connects the stovepipe to the ceiling support.
  5. Trim collar It hides the gap where the chimney comes through the ceiling.
  6. Attic insulation shield It keeps loose insulation and debris away from the chimney.
  7. Elbow Here it turns the stovepipe from upright to level, toward the wall.

Roof and outside wall 10

  1. Chimney pipe It is insulated between its walls. It comes in sections that lock together.
  2. Chimney cap It keeps rain out. One maker calls it a rain cap.
  3. Roof flashing Its base lies on the roof. Its cone fits round the pipe.
  4. Storm collar With the flashing it makes the opening in the roof weatherproof.
  5. Spark arrestor A screen that stops sparks from leaving the chimney.
  6. Wall thimble The chimney passes through it on its way out of the house.
  7. Tee Its side branch comes through the wall. Its top carries the chimney.
  8. Tee cap (tee plug) It comes off so the chimney can be inspected and cleaned.
  9. Wall support It carries the weight of the chimney outside the wall.
  10. Wall band (wall strap) It steadies the chimney sideways.

How this list was compiled: Every name checked on 2026-09-30, a name kept only where two independent sources use it: two factory-built chimney makers' installation instructions, read in Internet Archive copies (https://web.archive.org/web/20141114180604/http://www.duravent.com:80/docs/duraplusHTC_L820_2012-sept_w.pdf and https://web.archive.org/web/20190630181954/http://supervent.com/-/media/selkirk/reference-documents/common/file/installation/chimney/superventusa/superventsuperprousa-instructions.pdf); a wood stove maker's owner's manual (https://archive.org/details/manualsbase-id-600719); and Wikipedia, Flue (text only).

How it works

The parts of a wood stove chimney are shown on a factory-built metal chimney, the kind sold in sections. The first drawing takes it straight up through the ceiling and the roof. The second takes it out through a wall.

Up through the roof

The stovepipe runs from the flue collar on the stove to the ceiling, where an adapter joins it to the ceiling support box. From the box up, the pipe is insulated chimney pipe. It passes through the attic inside an attic insulation shield, then through the roof flashing and storm collar, and ends at the chimney cap.

Out through a wall

Here an elbow turns the stovepipe toward the wall. The chimney crosses the wall inside a wall thimble and meets a tee outside. The tee stands on a wall support, its tee cap comes off for cleaning, and wall bands hold the pipe to the wall on the way up.

  • Stovepipe and chimney pipe are different things: stovepipe is the thin pipe in the room, chimney pipe the insulated one beyond the ceiling or wall.
  • Makers' names differ: one says chimney cap, tee cap and wall strap where another says rain cap, tee plug and wall band.

Questions and answers

What are the parts of a wood stove chimney called?

Going up: flue collar, stovepipe, adapter, ceiling support box, chimney pipe, attic insulation shield, roof flashing, storm collar, spark arrestor and chimney cap. A chimney that leaves through a wall has an elbow, wall thimble, tee, wall support and wall bands instead.

What is the difference between stovepipe and chimney pipe?

Stovepipe, or connector pipe, is the pipe inside the room between the stove and the chimney. Chimney pipe is the insulated pipe that goes through the ceiling, attic, roof or wall. An adapter joins one to the other.

What does a storm collar do on a chimney?

It is a ring that fits round the chimney pipe just above the roof flashing. Together with the flashing it makes the opening in the roof weatherproof.

What is a wall thimble?

A sleeve that lines the hole in an outside wall. The chimney passes through it to reach the tee outside, where it turns and rises up the wall.
