Project step-by-step (8)

Step 1

Glass & Screen

  • Check the glass doors for cracks or defects, assuring they operate smoothly and are clear of soot.
  • Be sure spark screens move in their track smoothly and are tangle-free.

Step 2

The Hearth

  • The hearth includes the floor of the fireplace and the area in front of the fireplace.
  • The hearth should be made of non-flammable material and should extend a minimum of 16 inches from the front of the fireplace out to any combustible material (carpet, wood floor, etc.).
  • Clean out the ashtray and vacuum the hearth.
  • Inspect the firebrick for cracks and defects on the floor of the hearth and on the walls of the firebox.

Step 3

Log Grate

  • Be sure your fireplace has a grate for the logs to sit on.
  • Proper airflow around the logs will enable the logs to burn efficiently.

Step 4

Creosote Buildup

  • Creosote is the black tar-like natural byproduct of burning wood.
  • Creosote can build up inside the flue, on the damper or inside the firebox, causing chimney fires.

Step 5

The Damper

  • Use a mirror and light to inspect the damper door located just above the firebox. Be sure it opens easily and closes completely.
  • Look for creosote buildup.

Step 6

The Flue

  • The flue is the passageway in a chimney that conveys flame and smoke to the outer air.
  • A flue liner protects the inside of the chimney from collecting creosote. It has a smooth, easy-to-clean surface, enabling the fire to draft properly.
  • Again, use a mirror and light to inspect the chimney flue for any creosote buildup or defects. If available, use a snake inspection camera to get a closer look down the flue.
If no flue is present, do not use the fireplace! Stop and get advice from an expert.

Step 7

The Chimney Structure

  • Go outside and inspect the integrity and soundness of the chimney structure. If you’re comfortable, use a ladder to get on top of your roof.
  • Look for missing bricks and cracks in the grout between the bricks.
  • Make sure the flashing around the chimney is intact and installed properly.
  • Be sure the chimney cap and grate are clear of debris.
  • Look for black residue between the chimney bricks.
    • Note: This means creosote could be seeping through.
  • Look to see if your chimney sways or has a bow
    • Note: This means it could be structurally unstable.

Step 8

Be on the Safe Side

  • Replace batteries in carbon monoxide and smoke detectors.
  • Be sure your fire extinguishers are fully charged and easily accessible.
