A protective covering or housing for the top of a chimney intended for preventing the entry of rain, snow, animals, etc.

The pipe connecting a fuel-burning appliance to a chimney.
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.
Units of masonry projecting from or projecting upward and outward from the face of a wall or chimney in courses to form a support or ledge for a beam, rafter, or other member.
Chimney and stovepipe deposits originating as condensed wood smoke.
(also referred to as a Saddle) A ridge that extends from the back of the chimney to the slope of the roof, with the purpose of shedding water away from the connection between the chimney and the roof.
The slight slope or beveled edge on the top surface of a chimney designed to shed water away from the flue liner.
(Chimney Safety Institute of America) The CSIA is a non-profit, tax-exempt educational institution dedicated to chimney and venting system safety.
A valve, usually a movable or retractable plate, for controlling the flow of air or smoke.
Damper (Top Mount)
Located on the top of the chimney. Works by closing off the top of the flue when not in use so that cold air does not enter the home and that heat/cold air does not get drawn up an open flue. A cable is run down the side of the flue and attached to the side firebox wall. The cable controls the opening and closing of the damper
A connector from an insert or hearth stove to the first flue tile in a fireplace.
Double wall pipe where exhaust air is removed by the liner and combustion air is brought into the appliance between the inner liner and outer wall.
The rising gas creates a pressure difference called draft, which draws combustion air into the appliance and expels the exhaust gas outside through the chimney.
Dryer Vent Cleaning
The lint that is generated in drying the clothes ends up in the dryer venting system. The lint that is removed by hand from the lint trap on the dryer is a very small portion of lint that accumulates in the venting system. Build-up of lint causes the dryer to take more time in drying the standard load of clothes and becomes a fire hazard.
Chamber of a fireplace or stove where the fire actually burns.
Brick composed of clay and silica and designed to withstand high temperatures such as those found in a firebox.
Wood, coal, pellet, or gas heating appliances that fit inside an existing fireplace.
Sheet metal or other materials used in waterproofing roof valleys or the angle between a chimney and a roof.
The passage in a chimney for conveying flue gases to the outside atmosphere.
Special liner required by codes and standards to cover the inner surface of the flue. The liner serves as a buffer between flue gases and chimney walls and is designed to contain the products of combustion.
a gas burning appliance that burns propane or natural gas; the insert goes into an existing fireplace and creates a powerful heating source. The flue (venting) goes up through existing chimney and exhausts to the outside.
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.
Floor area within the firebox of a fireplace or a fireplace stove.
The interior component of a double-wall chimney.
A field-constructed chimney of bricks, stones or reinforced Portland cement concrete, lined with suitable chimney flue liners built in accordance with applicable building code requirements.
A hearth and firebox of solid masonry units such as bricks, stones, listed masonry units, or reinforced concrete, provided with a suitable chimney.
A single chimney containing more than one flue.
National Fire Protection Association – an International Codes and Standards Organization.
Small balls or blocks made of wood sawdust with no additives.
A thin coat of mortar applied to the inside of a masonry chimney or to the walls of a smoke chamber.
Chemical alteration of wood, coal, or other combustible materials as a result of the application of heat.
In reference to relining a chimney where pipe and insulation are placed through an existing flue that needs repair .
Chamber in a fireplace directly above the smoke shelf and extending to the base of the flue.
The area at the bottom of the smoke chamber created as the back wall of the firebox arches forward. The shelf is located at the intersection of the smoke chamber and the firebox. A damper is normally located on the forward side of the smoke shelf.
Single Flue Chimney Cap
A chimney cap designed to attach to and cover one clay tile flue.
Stainless Steel Liners
Stainless steel pipe, either rigid or flexible, made for relining flues of masonry chimneys when the original clay liner has cracked or broken. May also be used to create a lining in a masonry chimney that was made without a clay liner.
Soft, black, or brown, velvety carbon particle deposits inside appliances, chimneys or connectors, originating in oxygen-poor flames.
The tendency for warmer air to rise within a structure, creating lower pressure in the lower areas of the building.
Alteration to temperature inside a chimney or duct system that causes the metal surfaces to expand.
Fixed or removable ring, tube, or lining usually located in the hole where the chimney connector passes through a wall and enters a chimney or vent.
Opening above a fireplace firebox through which flue gases pass from the firebox to the flue. The fireplace damper frame assembly is usually located at the throat of a fireplace.
Top Sealing Damper
(also called a top-mount damper) 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 much more efficient than throat dampers because they provide a silicone rubber gasket seal rather than metal to metal.
Unvented, Ventless or Vent Free
Term used relate to either a low BTU gas log or a gel fueled fireplace that does not require a flue or chimney for ventilation.
UL – Underwriters Laboratories
Schebler Chimney Systems products carry specific certifications indicating satisfaction of safety standards set by Underwriters Laboratories.
A continuous passage from the flue collar to the draft hood. Flue gas temperatures at the outlet do not exceed 600 degrees.
Incorporating a closed circuit video camera and monitor, for inspecting the interior of flues and other inaccessible areas. This provides a very detailed part of the inspection process.
Enclosed appliances, most commonly constructed of steel or cast-iron, used for burning wood for the purpose of heating an indoor space.
