This section outlines the basic requirements for all chimneys, fireplaces, and vents. It covers definitions, materials, design, construction, and installation standards. It also includes general safety provisions, like clearances to combustibles, which are critical for preventing fires.

  1. Factory-Built Fireplaces

This section addresses the standards for factory-built fireplaces, including their installation and maintenance. It provides guidelines on the materials that should be used, the required clearances, and specific installation procedures to ensure safe operation.

  1. Masonry Fireplaces

The guidelines for masonry fireplaces, which are built on-site using bricks, stone, or other masonry materials, are covered in this section. It details construction practices, proper dimensions, clearances, and ventilation requirements to ensure safe and efficient operation.

  1. Chimneys

This section outlines the standards for different types of chimneys, including masonry, metal, and factory-built chimneys. It covers the construction, installation, inspection, and maintenance requirements to ensure that chimneys safely vent smoke and combustion gases from the home.

  1. Vents

This section provides guidelines for the installation and maintenance of vents used with gas, oil, or solid-fuel appliances. It covers vent types, materials, clearances, and installation methods to ensure proper ventilation and prevent backdrafting, which can lead to dangerous situations like carbon monoxide poisoning.
