Zero Clearance Chimney & Fireplace

Termination Cap or Chimney Cap:

The last piece of the top most part of a factory-built chimney pipe system, which serves the purpose of arresting sparks, keeping water out of the flue, and providing an outlet for cooling air on air-cooled chimney system.

Chase Cover (bottom pan):

A custom-made flashing that keeps water out of the chimney chase and home while providing an opening for the pipe termination.

Chase:

A pathway for a manufactured chimney pipe to pass through.  Chases are commonly built on the home to resemble a traditional chimney, to provide lateral support for the chimney pipe, and keep the cold weather from cooling the flue.

Firestop / Firestop Spacer:

A manufactured component of a factory-built chimney that separates the fireplace enclosure from the attic areas and still allows proper heat clearances to adjacent combustibles.  This slows the spread of fire through a home in the instance of a house fire and is required by building code.

Chimney:

The structure that passes through the construction of the home and encloses the flue (or flues).

Fireplace:

This is the firebox or place where you build the fire or place the gas logs.

Hearth:

The non-combustible floor area in front of the fireplace that is required for safety.  NFPA code requires the outer hearth to extend 18″ from the fireplace opening.
