Why do you clean a Fireplace?

Many people love coming home to see a cozy fire in the fireplace.  This is always a favorite for special family occasion.  Some people only burn wood in the fireplace occasionally while others have a warm fire every evening during the winter months.  A fireplace can also be extremely dangerous.  According to www.usfa.fema.gov, “Heating fires account for 36% of residential home fires in rural areas every year. Often these fires are due to creosote buildup in chimneys and stovepipes.”   The main reason for these fires is carelessness and a lack of cleaning.  We will discuss how to clean a fireplace.

How do you clean a Fireplace?

Cleaning and inspecting a fireplace annually can prevent multiple issues.  Many homeowners clean their own fireplace chimneys.  This is fine as long as you know how to thoroughly and properly clean a fireplace chimney.  As seen in the diagram below, there are multiple components to a fireplace and its chimney.  fireplace chimney

Once you seal up the opening of the fireplace to prevent dust from escaping, you can proceed to the roof.  The first thing you need to know is the size of your chimney flue.  The most common sizes for fireplace flues are 8″x13″ and 13″x13″.  You will need a wire brush that fits snugly inside the flue.  Now you can start by inserting the chimney brush from the top and working your way down.  Sometimes if the flue has extra creosote build up, you may need to pass the brush through the flue multiple times.

The most important thing to know when you clean a fireplace.

Look at the above diagram closely.  When you clean a fireplace flue, all the highly flammable creosote is not swept down the fireplace floor.  It is resting on top of the smoke shelf.  This is the most important spot to clean when you clean a fireplace chimney.  Now you have a pile of flammable creosote just a few inches above the flame.  You will need to reach up into the fireplace with a vacuum hose or other appropriate tool to remove all the creosote.  Once you remove all of the creosote that is on the smoke shelf, you now need to sweep out the rest of the firebox and discard of all the ashes.  These are the most basic steps in how to clean a fireplace and the chimney.








    *Note: If you have a terra cotta clay chimney
    flue lining, be sure to measure the true length and width of the
    inside of your chimney flue space.

    *If there is a terra cotta clay flue liner, does it protrude out of
    the top of the chimney at least 2 inches? If there are at least 2
    inches and the terra cotta clay is in good condition, you will use
    our stainless steel, terra cotta top plate that has a 1 1⁄2inch edge
    that goes all the way around (like a shoebox lid).

    *If your terra cotta clay flue is in bad shape at the top, you may
    need to just take a hammer and tap all around that terra cotta,
    taking it away to make the surface flat at the top of your chimney.
    In that case, you will simply use the flat top plate that comes with
    our liner kit.



    *Note: If you have a terra cotta clay chimney
    flue lining, be sure to measure the true length and width of the
    inside of your chimney flue space.

    *If it is on the back of the stove, is it parallel with the back of the stove or is it at an angle, like 45 degrees?

    *If it is at an angle you will use an insert stove adaptor (an insert liner kit) rather than a two-part tee with cleanout cap.


    Usually pellet stoves have an exhaust hole id of 3 inches. However, if you are going up more than 15 feet to the top of your chimney you need to use a pipe and/or flex liner that is 4 inches diameter.





    If you are only venting a hot water heater then the exhaust hole diameter is probably 3 inch diameter. If it is 3 inch diameter and you are going up more than 15 feet to the top of your chimney, you must use a 4 inch diameter flexible liner or ridged pipe for proper draft. We also suggest to go ahead and use a 4 inch diameter flexible liner or ridged pipe even if the total length is 15 feet or less.


    Not the depth or any other dimension inside your fireplace.
    Most gas log fireplaces require an 8 inch liner kit or rigid kit. But do not assume that is the case for the gas log fireplace kit you are installing. Obey the requirements for that specific unit that are in your installation/instruction manual.
