Brick Oven Chimneys

Any brick oven with a mouth and a face, which between them creates the flue, needs a chimney.

The chimney serves to move the smoke away from the face of the oven and the baker.

The height of the chimney determines how far away the flue gases go as well as the draft of the chimney.

For indoor ovens or ovens attached to homes, the 2 in 10 rule applies; the chimney must be 2 feet above the ridge of the house or 10 feet away from the building and roof.  Higher chimneys create better draft.

Chimney materials vary.  Outdoor ovens with low chimneys typically have clay flue tiles with stone or brick exteriors.  Indoor chimneys typically have insulated stainless steel chimney for ease and safety.  Occasionally it is possible to vent the oven flue into an existing masonry chimney.

A chimney chase is a wood structure built around the metal chimney to either conceal the metal or create a substrate for a stone or brick veneer.

All chimneys are capped with a metal or stone cap.
