Chimney liners serve as an extra layer between the inside of the chimney and the framing of your home. This provides another layer of protection as common defects can appear in the chimney. Defects, no matter how small, can begin a process that will further erode the chimney and can pose a threat to your family’s safety through the creation of health risks. Poisonous gases could potentially infiltrate the home.
The Importance of Furnace Liners
Furnaces, boilers and hot water tanks exhaust large quantities of water vapor during the normal combustion process of natural gas. Oil and gas furnaces produce by-products which can literally eat away the flue lining. Any type of furnace liner that is breached can cause a fire, since heat can reach combustible parts of the home. Clay liner that have gaps or cracks, allow this moisture into the interior structure which eventually deteriorates the masonry structure from the inside out. Additionally, gases vented from gas burning appliances can escape the lining and migrate into the home.
Blockage in a furnace flue is extremely hazardous because it can cause carbon monoxide fumes to enter your home
One of the most common problems that can occur with chimneys is blockage, regardless of what type of furnace fuel is used.
A furnace flue inspection should be scheduled
- At least once per year
- Before moving into a new home
- Before the installation of a new furnace
