CHIMNEY LINER (Chimney Flue)


A Chimney Liner aka Chimney Flue in a masonry chimney is defined as "A clay, ceramic, or metal conduit installed inside of a chimney, intended to contain the combustion products, direct them to the outside atmosphere, and protect the chimney walls from heat and corrosion." Although building codes vary from one state or locality to another, the installation of Chimney Liner or Flue Lining has been recommended since the early part of this century, and indeed most fire codes now mandate liners.

In the 1940's and again in the 1980's, masonry chimneys were tested by the National Bureau or Standards for durability due to rising concerns about their performance and safety.

The chimney is one of the most taken-for-granted parts of a home. Typically it tends to receive neither the attention nor the concern usually accorded other household service systems. The fact that chimneys may do their job reasonably well, even when abused or neglected, contributes to this atmosphere of indifference. Chimneys are far from the passive black holes that most people assume them to be. They perform several vital functions, and their simple appearance misrepresents their complex construction and performance requirements.

A chimney deteriorated by constant exposure to the weather can be a potential safety hazard.

Traditional dampers are located in the "throat" of a fireplace. They are made of cast-iron and are housed in a low-tech frame work. Cast-iron plate and frame do not seal tightly, allowing energy dollars to escape.

These cast-iron dampers do not seal well they have a leaky, rough, metal-to-metal seal.

Recent lab studies have shown that even a new throat damper can leak up to $200 of heating and cooling a year. Imagine how much energy an old, rusted out damper leaks!

The Lyemance Energy-Saving Damper seals tightly to save you money.

With an annual chimney inspection — and possible sweeping — you can improve fireplace and heating flue performance, and snuff out chimney fire and carbon monoxide concerns. Chimney inspection confirms if the chimney liner has the ability to contain the products of combustion (i.e., heat, moisture, creosote, and flue gases)

The byproduct of enjoying a crackling flame is creosote buildup (the major cause of chimney fires) and soot, which can restrict air flow and damage the fireplace chimney. The chimney for the heating flue, gas or oil,
