Here is a list of articles describing in more detail a variety of fire hazards that occur because of inadequate distance between a heating appliance, flue vent connector, chimney, or other building component and combustible materials.
Our page top sketch of a three-sided chimney is courtesy Carson Dunlop Associates. These articles on chimneys and chimney safety provide detailed suggestions describing how to perform a thorough visual inspection of chimneys for safety and other defects. Chimney inspection methods and chimney repair methods are also discussed.
Fire Clearances for several common types of manufactured chimneys are summarized at Fire Clearances for Metal Chimneys and just below are links to the specifications of each type of manufactured or metal chimney:
Fire Clearances for Metal Chimneys
FIRE STOPPING in BUILDINGS explains the need for a block to natural chimneys that can occur in building walls, speeding the spread of a building fire
Flue Vent Connectors - Heating Boilers, Furnaces, etc - the flue vent connector is a metal pipe connecting a heating furnace, boiler, or other heating appliance to its chimney. Failure to respect the necessary distance between the flue vent connector and combustible surfaces is one of the most common fire hazards in buildings. See Indoor Chimney & Vent Connector Fire Clearances for details of this topic.
Holes in Masonry Chimneys often are not noticed by building owners who do not enter attics or attic knee wall spaces where an older masonry chimney, particularly a brick chimney, may have lost bricks, cracked, or moved, creating a serious fire hazard.
Three-Sided Chimneys - Three-sided chimneys - chimneys which do not provide full masonry thickness or fire protection around all sides of the chimney flue.
Wood Burning Boilers, Furnaces Fireplaces Stoves are often installed without a building permit and without safety inspections.
Particularly when heating costs for conventional heating oil and gas are rising and high, these devices see extra service and may be run longer or hotter than usual in a home. The result is an increase in house fires where wood stoves, coal stoves, or fireplace inserts have been improperly installed or where the chimney has become creosote-laden and catches on fire.
