An alloy of stainless steel that is highly resistant to corrosion used for relining flues where flue gasses may contain highly corrosive elements. This alloy is used most often when relining a flue that will vent a modern, high-efficiency gas furnace. Since most of the heat generated by such an appliance goes into warming the home, flue gas temperatures tend to be relatively low. Low flue gas temperatures keep moisture in the flue gasses from evaporating and being eliminated up the flue. This combination of moisture in the flue gas, along with other chemicals that may be inducted into the flue from the surrounding environment, such as those from chemical cleaners and laundry supplies, can contribute to a very corrosive flue gas composition. AL29-4C is made to resist such corrosive environments over a long period of time.
ALUMINUM RELINING PIPE
Aluminum can be used as a relining pipe when it will be relining flues for low-efficiency gas furnaces. These devices produce neither enough heat nor enough moisture to constitute the need for a more durable stainless steel relining pipe.
An odorless, colorless, tasteless poisonous gas that is a byproduct of incomplete combustion.

The inner portion of the chimney that contains the products of combustion. It can be made of clay tiles or of metal. For flues to be serviceable, they must remain in tact, free from perforations, cracks or damage of any kind that could allow the products of combustion to pass into the living spaces of the home, or the heat from the products of combustion to endanger combustible materials near the flue such as framing, walls, ceilings, insulation, or floors.

GAS FIREPLACE LOGS
Artificial logs made of ceramic or fiber used in conjunction with a burner fueled by natural or liquid propane gas to simulate woodburning. These can be either vented or vent free.
Fireplaces that have either been converted from wood to gas or were constructed for gas. Most often their primary purpose is atmosphere rather than heat.
Heating or cooking appliances that use natural gas or liquid propane as their fuel.
The area directly in front of the opening of the fireplace usually constructed of masonry or other heat resistant material for the purpose of shielding the floor from excessive heat.
Interlocked flexible stainless steel relining pipe constructed from stainless steel of at least .007" thickness. Its weight and thick outer walls make it more impervious to damage and therefore easier to clean and easier to install in most masonry chimneys.
A heating device that returns to the heating environment more than 90% of the heat it generates. Such a device has, therefore, relatively low flue gas temperatures. The lower flue gas temperatures result in more moisture that condenses on the interior flue walls. This situation significantly increases the opportunity for corrosion within the flue.
A heating device that returns to the heating environment less than 90% of the heat it generates. Such a device has a warm enough flue gas temperature to allow for the vaporization and release to the environment most of the moisture created in the combustion process. This allows for a flue gas environment that is substantially less corrosive than that created by a high-efficiency gas furnace.
MULTI-FLUE CHIMNEY CAPS

National Fire Protection Association. The NFPA 211 is the authority on the current codes and standards pertaining to any oil, gas or solid fuel burning appliances.
That portion of a chimney located between two completely vertical portions that bends away from vertical for architectural reasons. This bend can be as much 45 degrees. Offsets in chimney are often difficult to negotiate when relining a chimney with stainless steel relining pipe. That's why flexible relining pipe is so often used in the relining process.
Interlocked flexible stainless steel relining pipe made and constructed of at least .007" thickness stainless steel and shaped into the form of an oval for a more optimal fit into certain types of masonry chimneys.
Interlocked flexible stainless steel relining pipe made and constructed of at least .007" thickness stainless steel and shaped into the form of a rectangle for more optimal fit into larger chimneys serving fireplaces.

Metal plates installed just above the firebox of a masonry chimney that are used for sealing the flue shut when the fireplace is not in use. Since they seal metal to metal, the seal is quite leaky even when the plates are new. Over time, the plates rust and deteriorate as they are exposed to heat and moisture. When this happens they lose almost their entire flue sealing capacity.
A device installed at the top of a chimney for the purpose of sealing the flue shut when the fireplace is not in use. They are often used as replacements for throat dampers that are installed just above the firebox when a masonry chimney is built. Top sealing dampers are as much as 90% more efficient than throat dampers because they provide a silicone rubber gasket seal rather than metal to metal.
