Gas Fireplace Hearth Extension Requirements

Gas fireplaces are an increasingly popular way to add comfort and ambiance to homes. However, there are also important safety considerations to keep in mind when installing a gas fireplace, including the need for a hearth extension.

A hearth extension is a non-combustible barrier that extends out from the fireplace opening. It helps to protect the floor and surrounding area from heat and sparks. Hearth extensions are required for most gas fireplaces, and the specific requirements will vary depending on the fireplace model and the local building codes.

When choosing a hearth extension, there are a few things to keep in mind:

Size: The hearth extension must be large enough to extend beyond the fireplace opening by at least 18 inches on the sides and 12 inches in front of the fireplace.
Material: The hearth extension must be made of a non-combustible material, such as tile, stone, brick, or metal.
Thickness: The hearth extension must be at least 1/2 inch thick.

In addition to the above requirements, hearth extensions must also be installed according to the manufacturer’s instructions and local building codes.

Here are some additional tips for installing a gas fireplace hearth extension:

Make sure the hearth extension is level and securely attached to the floor.
Seal the joints between the hearth extension and the floor to prevent heat and sparks from escaping.
Keep the hearth extension clean and clear of debris.

By following these requirements and tips, you can ensure that your gas fireplace is safe and enjoyable for years to come.
