Until a few years ago, Clay or Terra Cotta tile has been the standard material used in masonry chimney construction . These flues are susceptible to cracks and breakage during a chimney fire, or to deterioration after years of use and/or due to lack of cleaning and maintenance.
Even if you know your chimney is lined, and the chimney has seemed to perform fine for decades or a brand new chimney, an annual inspection will either find a safety problem or help you rest assured that your venting system is in good condition.
Poor construction, creosote, water damage, moisture damage, amount of usage, efficiency of the furnace and mortar deterioration are some of the reasons why these flues must be re-lined.
Flexible Stainless Steel chimney liners are the most cost effective and efficient re-ling product available.
Why should you even bother to install a liner? They aren’t cheap, but their benefits definitely outweigh their cost. The liner will protect your flue system, damaged or not, from the transfer of heat in your system to nearby combustibles.
Liners also keep your masonry safe from byproducts of combustion that can be extremely corrosive and damaging to your flue system. The gases produced by combustion will actually eat away at or deteriorate the mortar located in between the flue tiles in your chimney.
The question is what type of liner and who installs it.
Alloy is the strength of stainless steel to resist corrosion. The following fuels should be matched with following alloys:
Wood, Pellet: 304, 316, 321 or 316Ti Alloy
Coal, Oil, gas (cat, 1): 316 or 316Ti Alloy
316TI is the better of the bunch, having traces of titanium in it, to help prevent corrosion.
The liner you should use is constructed of high quality 316Ti stainless steel for extra protection against corrosion and tested to withstand a chimney fire of up to 2100 degrees Fahrenheit.
The seams should consist of many layers that are crimped for a super strong and airtight
If you have a clay flue, or even if you have a masonry flue with no lining, have a thorugh inspection done immediately, to give you the the piece of mind in knowing that you and your loved ones are safe!
