The chimney’s flue builds up with creosote which needs to be professionally swept by a licensed chimney sweep. In some cases there could be a very thick layer of creosote that could be very difficult to remove, and very dangerous not only to breathe in, but creosote (especially stage 4 creosote) is highly flammable, which can cause chimney fires.

The flue pipe’s role is to carry harmful fumes from a furnace outside the house. It is also referred to as a furnace exhaust stack or vent, and plays a vital role in household safety. Furnaces work by using oxygen, heat, and fuel to produce and distribute warmth. During this process, they emit harmful combustion gases like carbon monoxide, nitrogen dioxide, and sulfur dioxide. Redirecting these gases outside the house is crucial to protect human health.
Furnace flue pipes play a vital role in furnaces, as they carry harmful fumes from the furnace to the outside, ensuring that families breathe in clean and safe air. Inhaling these fumes can lead to severe health issues and, in some cases, fatalities, underscoring the importance of keeping these hazardous gases outside. To ensure optimal operation, it is crucial to maintain, inspect, and replace your furnace flue pipes regularly.
Corrosion, regular wear, weather conditions, debris, and bird nests have the potential to harm furnace flue pipes. The expansion and contraction of pipes due to temperature changes may lead to leaks. Moreover, inadequate airflow can hinder a flue pipe from receiving sufficient air, causing it to draw combustion gases inside the house. A deteriorated or damaged flue pipe poses risks as it could allow harmful fumes to enter your home. If you observe any of the following indicators, your furnace flue pipe might require replacement:
Chimneys, Fireplaces an vents shall be inspected at least once a year in accordance with the requirements of 15.1 (NFPA211. 14.2.1)
Cleaning, maintenance & repairs shall be done if necessary (NFPA211.14.2.1).
If the flue liner in a chimney has softened, cracked or otherwise deteriorated so that it no longer has the continued ability to contain the products of combustion (I.E. heat, moisture, creosote & flue gases), The liner shall be removed & replaced, repaired, or relined with a listed liner system. (NFPA211.14.9)
Masonry chimneys shall be provided tight (NFPA211. 14.2.1)
