The Problem

During original construction, it is not uncommon for masons to improperly align the flue liners or neglect to fill the joints between the flue liners with the appropriate refractory mortar. As stated in The BOCA National Mechanical Code, M-1207.2.1 Fire-Clay flue liner:  The fire-clay flue liner shall be installed ahead of construction of the chimney as the chimney is carried up and carefully bedded one on the other in an approved medium-duty refractory mortar, with close joints left smooth on the inside. Even if the mason filled the joint with mortar, it most likely was the same mortar used to lay the brick, block or stone, which is not an approved refractory. In fact, standard mortar has almost no refractory properties. Standard mortar in the joints of flue liners cannot withstand the adverse conditions present within a chimney environment. The result of using standard mortar is rapid deterioration of the joint, ultimately leaving dangerous openings between the flue liners.

STAINLESS STEEL CHIMNEY LINERS

Fireplace LinersAlso known as fireplace liners, flue liners, chimney flues, or flexible chimney liners.  Chimney liners are the passageway in the fireplace or furnace flue through which gases (carbon monoxide) and smoke travel in order to escape your home safely.

Stainless steel chimney liners separate the fireplace or the furnace exhaust from the rest of your house. A wise homeowner will want to know about the condition of the whole chimney, including the fire liners, in the home he/she owns or plans to buy.

Advantages of stainless steel chimney liners :

  • Stainless steel chimney liners have a lifetime warranty.
  • Stainless steel chimney liners provide superior fire protection for your home.
  • Meet code requirements for safe operation and resale.
  • Stainless steel chimney liners are one long continuous piece not sectional (no connectors or fireplace mortar joints to shift or separate like clay tile chimney liners).

When your original construction fire clay flue tile liners are cracked, the cracks open during the heating phase and allow gases to pass through to your chimney walls. The gases, being acidic, attack the masonry and will shorten the life of your masonry structure. In addition, this will lead to carbon monoxide in your home.  Stainless steel chimney liners are needed to exhaust all poisonous gas and chimney smoke out of your home safely.

The NFPA (National Fire Protection Association) Code 211 requires that all masonry chimneys be lined. Unlined chimneys are so unsafe that researchers characterized building chimneys without chimney liners as “little less than criminal”.  The installation of fire liners in chimneys has been recommended since the early part of the 1900’s.
