The lining is one of the most important parts of the chimney. It channels heat and gases up through the chimney top and blocks the resulting heat from causing combustible materials from catching fire. Cracked or damaged lining isn’t good and it’s important that you replace it before you start using your chimney again.
Your fireplace should be a great addition to your home, but you must be careful because it can also be dangerous. So, it’s important to understand fireplace safety before using this home element.
