Title: How to Prevent Fireplace Chimney Fires


1
  • How to Prevent Chimney Fires
  • The chimney is more than just an architectural
    structure in your home. It has an important
    function which is to carry toxic gases emanating
    from the fireplace, furnace or stove out of your
    home. As you unwind in front of your fireplace
    and bask in the sparkling flame, the condition
    of your chimney is probably the farthest in your
    mind. However, the truth is, if you do not spare
    a thought for the health of your chimney then
    that relaxation might not last.
  • This is because dirty chimneys are prone to
    chimney fires, which can lead to injuries and can
    also damage structures as well as homes.
  • Warning Signs
  • To prevent a chimney fire one must be sure its
    clean, that the chimney doesnt have a massive
    buildup of soot or creosote and is properly
    build. Some factors may warn you that the
    chimney might go up in flames. Whenever the
    following signs appear, its best to call a
    professional chimney sweep or to get rid of it
    immediately
  • A loud popping and cracking noise and a lot of
    dense smoke. It can create an intense smell that
    emanates out of your chimney
  • A massive buildup of a dark brown or black powder
    in your chimney, which can be creosote or soot.
    Creosote flakes and pieces found on the roof or
    ground are also a cause of worry and should be
    cleaned immediately
  • The warped metal of the damper, a warped metal
    smoke chamber connector pipe or a warped
    factory-built metal chimney
  • Cracked or collapsed flue tiles, or tiles with
    large chunks missing
  • Discolored or a distorted rain cap
  • Damaged roofing material, which is mainly caused
    by hot creosote
  • Cracks in exterior masonry
  • Evidence of smoke escaping through mortar joints
    of masonry or tile liners.
  • Chimney fires can be explosive and easily
    conspicuous to neighbors and passersby.
  • However, some are less dramatic due to the fact
    that they do not get enough air to fuel them and
    one would only notice during a chimney
    inspection. Still, they can cause damage to the
    chimney structure.

  • What are the effects of chimney fires on
  • Factory Built Metal Chimneys
  • Most factory-built metal chimneys require special
    tests before they are installed. These include
    testing the ability of the chimney to withstand
    high flue temperatures without sustaining
    damage. However, if there is a chimney fire,
    damages might still occur and factory-built
    metal chimneys will need to be replaced if
    damaged in any way.
  • Masonry Chimneys
  • Regardless of whether the flue is older, tile
    lined chimney fires in a masonry chimney can
    melt mortar, crack tiles and damage the outer
    masonry material. This happens mostly when
    thermal shock occurs causing tiles to crack and
    mortar displaced. This gives a leeway to flames
    and is extremely hazardous.
  • How to Prevent a Chimney Fire
  • Use dry wood. Wet wood does not burn as hot as
    dry wood and churns out more smoke. Wet wood
    often leads to rapid creosote buildup.
  • Clean your chimney. It is often easy to tell if
    the stove pipe needs cleaning, i.e. when the
    smoke does not draft up but comes out of the
    door.
  • Burn your wood stove daily. Burning wood stove
    hot enough on a regularly will help prevent
  • the buildup of creosote.
  • Use creosote remover powder. This is a powdery
    substance that when put in woodstove before
    burning a hot fire turns the creosote into a
    powder. This does not in any way substitute for
    cleaning your chimney, but rather helps reduce
    creosote and minimizes chances of a creosote
    chimney fire.
  • Burn the hardest firewood you can find. Softwood
    has a lot of pitch in them which also
    contributes to the creosote buildup and chimney
    fire.
  • Regular chimney cleaning. Ensure regular cleaning
    of your fireplace interior including the floor.
    Also, vacuum and ensure you wear protective gear
    while cleaning your fireplace.
