Chimney Fire in Prairie Village, KS Captured on Camera

 

A chimney fire occurred in February of 2023 in the 4600 block of West 82^nd St, Prairie Village Kansas. The neighbor captured photos of the fire department putting out the fire and sent them to us. The neighbor happens to be a client of HearthMasters. Since it is not common to get photos of chimney fires while they are in progress, we decided to post this event in order to warn people about the dangers of chimney fires.

Chimney fires occur when flammable creosote ignites inside a smoke chamber or flue due to an errant spark, a fire that is too large, or the use of paper, which can be pulled upward by draft and ignite the creosote. The amount of creosote inside the flue, along with draft, will determine how long the fire keeps going.

Most chimney fires are extinguished by expanding creosote, and often homeowners are unaware that they occurred. The damage may be found later by a chimney sweep. The interior and exterior of a chimney may be severely damaged by expansion and contraction caused by the heat of a chimney fire, making it unusable, and causing thousands of dollars of damage. Chimney fire damage is covered by homeowner’s insurance.

Some chimney fires are noticed at the time the occur, and that is when the fire department is called to put it out. Homeowners should always call the fire department when a fire occurs because it might not be contained inside the chimney if there are any breechings in the masonry or if combustible framing is incorrectly installed next to the chimney, which unfortunately happens too often. 

One of our customers stayed up all night watching his house after a chimney fire occurred, and had to call the fire department back three times because it kept reigniting combustible framing in the wall area. Had he not stayed up the house may have burned completely, 

After a chimney fire has occurred, the chimney should be inspected by a qualified professional chimney sweep using a chimney camera. If damages are found, which is very likely, the sweep should document the damages with photos and a written evaluation report for insurance purposes. Homeowners should not attempt to remove burnt creosote or do an inspection themselves.

How to avoid chimney fires

Chimney fires occur during cold weather months when people use their chimneys. A chimney fire occurs when accumulated creosote in a flue or smoke chamber ignites from a spark.

All wood creates creosote - even dry hardwoods- so it is imperative that flues serving fireplaces or wood-burning stoves, or fireplace inserts are swept regularly to remove this flammable substance. The NFPA recommends sweeping once per year for fireplaces, and at least twice during the season for heating appliances (wood stoves or inserts). A house fire can occur if the fire in the chimney escapes the flue liner or if burning embers fly out of the top of the chimney onto the roof. (Asphalt roofs can catch fire as well as wood shingle roofs). 

Most chimney fires are of short duration and go unnoticed by the homeowner - with damages usually found later during an inspection by a chimney sweep. 

 

Signs of a chimney fire:

•  Loud whooshing or roaring or freight train like sound
•  Flames shooting out the top of the chimney
•  Red glowing stove pipe
•  Backup of smoke into the house
• Sudden poor draft

It is a good idea to keep a chimney fire extinguisher near your fireplace or wood stove and use it if you notice a chimney fire, then get out of the house and call the fire department immediately. Fire can spread to nearby combustibles and cause a house fire. Be sure to keep an eye out for smoke smell or flames even after the fire department is gone because interior wood framing could smolder for hours afterwards and ignite if it gets enough oxygen.

After the fire: Call your local professional chimney sweep to have a thorough inspection and any needed repairs completed before using the appliance again. Most chimneys are severely damaged on the interior during a chimney fire and should not be used until inspected by a qualified professional. Any breaks or blown out sections in flue tiles or warped or buckled seams in steel liners or chimneys can be a fire and Carbon Monoxide hazard.

Tis the Season for Chimney Fires

It’s that time of year again – the season for chimney fires. As a chimney and fireplace service company we see the results of the lack of proper maintenance and improper installation that can cause fires and destruction of property, and in some cases injury or death. Chimney fires are preventable and should be avoided because of the risk that they could escape the chimney and catch the house on fire.  

All types of wood – even hardwood- creates creosote when burned. It accumulates on flue and smoke chamber walls and must be periodically removed. Chimney sweeping should be done by a professional chimney sweep who has the proper equipment to do the job right. First, tarps and a vacuum are set up. Then the sweep brushes the flue with wire brushes for masonry flues, or poly brushes for metal flues, and removes the creosote from the flue and fireplace or wood stove. Next, the sweep should run a chimney camera through the chamber and flue to inspect it and make sure there are no broken flue tiles, missing mortar, or blockages, or in the case of a manufactured fireplace or stove, that all of the metal pipe seams are solid and unwarped. The chimney sweep will then do a visual inspection of the interior and exterior chimney, check for proper clearance to combustibles and proper installation of components, then provide a report on its condition.

It is very common for repair issues to arise with any type of chimney. Regular maintenance is
needed in order to keep the system functioning properly. Exterior masonry repairs should be done in the spring or summer, but if the chimney needs a new flue liner this can be done any time of year. Chimney fires can cause costly damage to a masonry or metal chimney system. If relining is necessary, it will cost thousands of dollars. Fortunately, chimney fires are covered by homeowner’s insurance. However, it is best to avoid a chimney fire in the first place.  

According to the U.S. Fire Administration there were 83,300 house fires caused by heating in 2018.  The National Fire Protection Association’s latest press release dated November 22, 2010 estimates that 66,100 home fires caused 1.1 billion in property damage, 1,660 injuries and 480 deaths in 2008, which was a 0.5% decline from 2007.  15,200 (23%) of all home heating fires are creosote fires, which the NFPA calls “failure to clean” fires that were confined to a chimney or flue, or involved solid-fueled space heaters, chimneys, connectors, and fireplaces.  See the entire news release at www.nfpa.org

Tips:

1.       Never burn a dry Christmas tree in a fireplace.

2.       Only burn dry, seasoned hard or soft cordwood in a stove or fireplace

3.       Only burn one piece of hedge to two pieces of other types of wood.

4.       Have the chimney inspected and swept annually, or twice per season if using a wood stove.

5.       Have a Draw Collar installed for hard-starting wood stoves.

6.       When purchasing a new home have the chimney inspected by a CSIA Certified Chimney Sweep prior to closing so you know what you are getting into.

7.       If you hear a whooshing sound, or freight-train like sound, or the room fills with smoke, get out of the house and call the fire department. Go outside and see if flames are shooting out the top of the flue.

How to Avoid a Chimney Fire that Can Lead to a House Fire

House fire caused by flammable
creosote and improper construction

Creosote is a flammable substance that must be removed from the flue and smoke chamber periodically in order to avoid having a chimney fire. 

Since all wood creates creosote, including dry hardwoods, creosote is impossible to avoid when burning wood in a fireplace, wood-burning stove, circulating fireplace, or stove insert.

Creosote can only be removed by brushing the flue and chamber out with wire or poly brushes that are made especially for this purpose. Professional chimney sweeps know what size and type of brush to use for the type of flue system installed. There are many different types of venting systems, so knowing how to properly maintain each type is critical.

In a masonry chimney with a wood-burning fireplace the most common type of flue system is made out of vitreous clay tile, and the smoke chamber is usually made out of brick, stone, or block. This type of venting system accumulates more creosote than a stainless steel flue liner does because it is more porous.

Stainless steel flue liners don't accumulate as much creosote if they are properly insulated and installed correctly, but can be damaged by a chimney fire so maintenance is necessary.

Smoke chambers that are not parge coated with insulating mortar per IRC Code requirements allow more creosote accumulation due to their rough surfaces and corbels which decrease the flow of smoke and tar vapours.

The National Fire Protection Association and the National Chimney Sweep Guild recommend that creosote be removed after 1/8" accumulation on flue walls.

The creosote being removed should be stage 1 which is very light and ash-like, or stage 2 which is more dense. If there is any accumulation of stage 3 glazed baked-on tar-like creosote, something is not right with the system, the fuel being used, or the operation of the appliance. Stage 3 creosote is the most flammable type, and is most often associated with chimney fires.

A chimney fire occurs when a spark ignites the flammable creosote, usually in the smoke chamber just above the damper, and flame may spread through the remaining fuel source (creosote) on the flue walls.

Stage 3 Creosote on flue walls

Chimney fires can be of short or long duration, but almost always cause damage to the smoke chamber and flue liner due to the quick temperature differential that occurs to the masonry during a chimney fire. Damages may occur to the face wall above the fireplace opening inside the house, to the back wall of the chimney, or to the top portion of the chimney and cement cap due to expansion. Fresh breaks may be found in the masonry and cement cap in a masonry chimney.

Burnt creosote that has been on fire

In a manufactured fireplace and metal chimney damages may occur to the metal smoke chamber and metal chimney pipe in the form of buckling, warping, and opening of seams. With a Class A chimney system serving a wood-burning stove, the same type of damage can occur.

In either case, the damage must be repaired, or parts replaced before further use because the system is no longer functional if it has damages.

Unfortunately, most chimney fire damage is found only during inspection of the system during routine chimney cleaning/inspection maintenance by a professional chimney sweep. Most chimney fires go unnoticed by homeowners when the fire occurs because they either don't recognize the whoosh of air and increased draft during a chimney fire, or are out of the room when it occurs and the fires goes out before they return.

After a fire has damaged a chimney system, the flue liner and chamber may have cracks and gaps that would allow a second fire to escape to nearby combustible wood framing. This is how a house fire due to chimney fire commonly occurs. Another way a house fire can occur is if flame and sparks shooting out the top of the chimney catch the roof on fire.

Water damage from rain and condensing acidic flue gasses often causes mortar joints between tile liner sections to deteriorate and leave gaps, which may also allow heat and flame to escape the flue system and cause a house fire.

The only way to know if the flue system has damages is to sweep it first to remove creosote, then run a special chimney camera through the chamber and flue. Photos may be taken with this type of camera. If damages are found, do not use the appliance until it is properly repaired by a professional chimney contractor.

Signs of a Chimney Fire Everyone Should Know

By Marge Padgitt
HearthMasters, Inc.  

Chimney fires are more common than most people realize. Most chimney fires occur without the

homeowner noticing because the fire often is snuffed out by expanding creosote inside the chimney.

Chimney fires can occur in chimneys that are connected to wood-burning stoves, open wood-burning fireplaces, and fireplaces with gas logs installed. It only takes a spark or heat to ignite creosote.

Fire damage is often found during a routine inspection by a professional chimney sweep. Signs that a chimney fire has occurred are cracked or shattered flue tiles; blown out sections of flue tiles; blown out mortar joints in the flue and smoke chamber; smoke damage to the fireplace face or other areas of the house; expanded and cracked masonry at the facial wall above the fireplace opening, back of the chimney, or top of the chimney; a cement cap that is lifted or broken bond with the top course of bricks; cracks in a cement cap; damaged chimney cover; or damaged stainless steel chimney with warping or buckled seams.

Damages to a masonry chimney or steel chimney can be extensive and very costly to replace,  and if the fire escapes the chimney, a house fire can endanger life and property. Avoiding a fire in the first place is the smartest thing to do.

What are the signs that a chimney fire is occurring? During a chimney fire, the following may occur:

·       Loud roaring or whooshing sound coming from the chimney

·       Freight-train like sound

·       Loud cracks or pops (this is the flue tiles breaking)

·       Sudden smoke backup into the house

·       Flames shoot out the top or sides of the chimney chase

·       If not contained inside the chase, a house fire may occur

What to do in case of a chimney fire:

·       Throw a chimney fire extinguisher in to the firebox

·       Shut off the air supply by closing glass doors or closing the combustion air intake

·       Get the family out of the house

·       Call the fire department

·       Keep watch for at least 48 hours in case fire ignites again in nearby combustible framing

·       Call a professional CSIA Certified Chimney Sweep to inspect the chimney and provide an evaluation report before further use. Be sure to follow the sweep’s advice regarding any repairs needed. Find a professional chimney sweep at the Midwest Chimney Safety Council site at www.mcsc-net.org or the Chimney Safety Institute of America site at www.csia.org. 

How to avoid a chimney fire:

Wood should be split and stacked at least 6 months before use

·       Have the chimney inspected and swept on a regular basis by a professional CSIA Certified Chimney Sweep- once per year for open fireplaces or twice for wood-burning stoves or inserts.

·       Burn only dry cordwood - get a moisture meter and make sure that there is only 15% moisture content in the wood.

·       Never burn pine (except hard yellow pine), hedge, railroad ties, wrapping paper, or treated wood.

·       Do not depend on a chimney sweeping log to remove creosote and do an annual inspection.

·       Use Anti-Creosote-Remover spray on logs each time you burn to reduce creosote buildup.

·       Realize that all wood creates creosote and maintenance is necessary to remove flammable creosote.

·       Burn hot fires rather than small or smoldering fires. Smoldering fires create a lot of creosote buildup and are the primary reason that chimney fires occur.

·       Read the owner’s manual.

Keep Your Fireplace in Tip Top Shape for Winter

Keep Your Fireplace in Tip Top Shape for Winter 

By Marge Padgitt, President of HearthMasters, Inc.

The following are some tips for keeping your fireplace in good order for the winter: 

•    Have all chimneys inspected annually by a professional chimney sweep to be sure they are in good working order. The sweep will inspect the interior with a chimney camera and the entire exterior wood or masonry structure visually.  He will look for cracks, gaps, or missing mortar joints in the flue, check for proper flue size, check the smoke chamber and fireplace condition, flashing, crown, and chimney cover.

•   Have flues serving wood-burning appliances swept annually or bi-annually to remove flammable creosote and reduce the risk of chimney fire. All wood creates creosote - even dry hardwoods. 

•   Have the furnace or water heater flue inspected annually by a professional to be sure it is not a Carbon Monoxide risk. Blockages or flues in poor condition can be a CO risk. Even a CO detector does not register all levels of CO. 

•   Have gas direct vent fireplaces or stoves tuned up and serviced annually to assure proper performance. Dirt, dust, and spiders clog orifices and can make the unit inoperable. Annual service is required by the manufacturer for warranty coverage on all brands.

•   Have a chimney cover installed to keep damaging rain and animals out of the flue. A cover should be installed on each flue or a custom-cover can be made to cover all flues and the cement crown.
  
•   Masonry problems such as cracked mortar or bricks, deteriorating mortar or spalling bricks should be repaired in the spring and summer months to allow for proper curing so plan accordingly.

•   Have an elastomeric sealant applied to the cement crown to protect it from weather damage.
