Chimney Liners... Why Would I Need One?

Why Do I Need A Chimney Liner?

Figuring out if you need a chimney liner may seem like an overwhelming decision. However, the benefits of a chimney liner outweigh any costs. Safety, efficiency, and easy maintenance are all great advantages of installing your own chimney liner.

Installing a chimney liner will help ensure the safety of your family and home. Fireplaces produce toxic gases that may not be routed out the top of your chimney, instead they may enter your home. Toxic gases include carbon monoxide and other combustion gases. Having a chimney liner will provide a safe outlet for gases to leave your fireplace. The liner is an efficient way of exiting gases from your home. Also, chimney liners that are made from flexible stainless steel expand and contract with temperature. The expansion and contraction of the liner does not allow as much creosote to buildup. Creosote is extremely flammable and can easily cause a chimney fire.

Creosote buildup can cause chimney fires, but so can overheating. A chimney liner protects the chimney's masonry-work from becoming overheated and cracking. When this occurs, gases can enter the home and ignite a fire in the flue. The liner will guard the chimney from wear and tear and last a lifetime. Rock-Flex chimney liners are provided a lifetime warranty just for this reason.

Energy efficiency is another advantage of chimney liners. Chimney liners help burn hotter fires while minimizing heat loss because they keep the optimal airflow within the flue. Therefore, since you will be burning an efficient fire, you will sure see money savings in energy bills because the need for adding fuel is reduced.

Not only do chimney liners save you money through energy efficiency, they are also much easier to maintain than a traditional fireplace. Chimney liners do not have as much creosote buildup as brick and mortar chimneys. They are also more accessible and easier to clean.

How To Install A Chimney Liner Through A Damper

 

When installing a chimney liner, getting the liner through the damper opening can be something of a challenge. A typical 6" round liner is 6.25" on the outside diameter. Your damper opening is probably in the range of 5". There are generally two ways to get around this problem.

Option 1: Widen the damper opening. Remove the damper door. This may give you some added clearance. If not, you can continue by removing the damper housing that it usually mortared in place. Sometimes using a reciprocating saw (sawzall) or grinder and just cutting an opening large enough to slide the liner through is sufficient. Should you need additional clearance, brick removal is permissable since that is a non-structural area.

Option 2: Ovalize a section of the liner. You will need to take a couple of measurements: the opening width of the damper, and the distance you will need from the damper to the exhaust of your insert or stove, which determines the length that you will need to ovalize. Once you have that information, uncoil the liner, and starting at one end, ovalize the liner to the thickness and length needed.

How to ovalize the liner: There are number different items you could use to ovalize the liner, and they will give you the same results. One we have found that works well is a wide board (a 2x10, perhaps, or something close to that) a couple of feet in length. Start with the liner secured with your knees, and begin from the end by pressing down and work towards the length you need. Continue pressing down, going forward then back again until you have the width and length needed. The liner is sturdy and will not crush, so you can apply pressure to it to achieve the dimensions needed.
Make sure you have the correct length and thickness, so you won't have to remove it and redo it. Once you have the liner ovalized, install that end first down the chimney flue. After you have it through the damper, re-form the very end of the liner back to round with your hands so the connector will fit.

 

When Is It Time To Reline My Chimney?

You Know It's Time When...

A chimney liner, or flue, is the inner portion of a chimney that contains and channels the products of combustion. For a chimney liner to work properly, it must be free from perforations, cracks, or damage of any kind. If it isn't intact it can allow the products of combustion, such as carbon monoxide, moisture, smoke, and creosote, to seep into the living spaces of the home, or the heat from the products of combustion to pose a fire risk to combustible materials near the flue such as framing, walls, ceilings, insulation, or floors.

Repair or replacement chimney liners typically are made of either rigid stainless steel or flexible stainless steel. Most masonry chimneys are constructed with an inner liner of clay tiles. Relining systems are available if an original clay tile liner was either never installed, or when the tile lining cracks, crumbles and deteriorates over time. Water damage, chimney fires, or just age can cause the deterioration of your clay liner.

Tips on Relining

To figure out the maximum size flue liner you can install, go on your roof and measure the inside diameter of your existing flue opening. You also need to know what length of liner to buy. If it's for a fireplace chimney and you still want to use it as a fireplace, measure from the top of your chimney to the top of the smoke chamber. You must also measure the size of your fireplace opening, height and width. If you're relining in order to use a wood stove, measure from the top of the chimney to where you'll be connecting the stove. Also measure the inside dimension of the exhaust on your wood stove, which establishes the size of liner you need.

When deciding between a rigid or flexible liner bear in mind that, although a rigid liner has the advantage of smooth walls, a flexible liner is far easier to install. Rigid pipe has to be assembled as you install it and long lengths can mean trouble if you happen to drop the partially assembled pipe down the chimney. A general rule of thumb is if you only need to reline about 12 feet (3.7 meters) of straight chimney, go with rigid liner, otherwise choose flexible.

Insulating your liner is important because it will give your chimney a better draft and help it stay cleaner longer. Especially when burning wood, an uninsulated flue will quickly lead to a build up of creosote.

Characteristics Of A Good Chimney Liner

Rockford Chimney Supply

Flexible chimney liners are stainless steel cylindrical tubes that reside inside a masonry chimney. These steel tubes are inserted into a masonry chimney, often within the existing flue. A flexible chimney liner is used most often with masonry chimneys that have several bends or even imperfections in them and that are not completely straight. Most flexible chimney liners come in a wide range of sizes to fit your fireplace or fireplace insert.

A chimney liner, or flue, is very important in the construction of your fireplace since it is the innermost portion of a masonry chimney that funnels smoke away from the heating source. For a chimney liner to work properly, it must be free from holes, cracks, or any other kind of damage. If the liner is not completely intact it can allow the products of combustion, such as carbon monoxide, moisture, smoke or creosote to seep into the living spaces of the home. Sometimes the heat from the fireplace poses an additional fire risk to combustible materials near the flue such as framing, walls, ceilings, insulation, and even floors.

Characteristics of a Good Chimney Liner
One of the most important reasons to buy a good flexible chimney liner is to create an additional barrier between a chimney fire and your family. As chimneys age, they do begin to deteriorate and threaten the safety of the home. A flexible chimney liner also allows for easier cleaning of the chimney and extends the life of your masonry chimney.

High-efficiency furnaces that are found in recent renovations and new homes vent acidic moisture into chimneys. Over time this moisture can destroy a masonry chimney. A white film on the chimney’s bricks is a sure tell sign of excess moisture in the masonry chimney. If you notice this white film, invest in a good flexible chimney liner to prevent any damage to your home.

What to Look For in a Flexible Chimney Liner
Most flexible chimney liners are made of stainless steel alloy. An average cost for stainless steel flexible chimney liners is $20 to $40 per foot, which makes them a reasonable choice when replacing or adding a chimney liner to your existing masonry chimney.

When purchasing your flexible chimney liner, look for the properly szed liner possible. Once installed the liner should be insulated. Proper insulation allows the liner to heat up correctly and allows for a good draft and overall heating of the home. Insulation could be a insulation blanket, organic vermiculite, or even a concrete insulation mixture that is poured down the flue to fill the extra space between the chimney liner and the flue.

Clay Flue Liner Pit Falls & A Solution

Hearth and Chimney Tips Presented By Rockford Chimney Supply

A clay flue liner is found along the pathway of the exhausting fumes in a chimney. It is essentially a functional layering, found along the chimney’s flue (outlet). Flue liners are not needed in all chimneys. However, clay tile flue liners do deteriorate over time.

The best solution when the tile is showing signs of deterioration is to replace it with a stainless steel chimney liner. Stainless steel chimney flue liners can be easily installed without any professional help.

Understanding Clay Flue Liner Advantages

Clay tiles aren’t the most durable material and need to be inspected frequently. If any signs of deterioration show in the terra cotta tile it is recommended you install a rigid or flexible chimney liner kit, easy to install.


Visit Rockford Chimney Supply at http://rockfordchimneysupply.com/ they have a wealth of information on chimney lining kits and are there to answer any questions you may have before making a decision. For improving the chimney’s safety and the safety of your family please note this article, possibly bookmark it for future reference. The internal walls of older chimneys become porous over a period of time. Thus, they present an easily-attachable surface for smoke and chimney soot.


If such materials stick to the flue, they will cause a chimney fire if neglected. Metal flue liners ensure that debris and gases produced from burning fuel into your chimney do not stick to the internal wall of the chimney liner.

Rock-flex flue liners have another fire-fighting feature. They have been UL tested and approved to withstand temperatures up to 2100 degrees. This means that even if a chimney fire occurs, the liner will withstand the heat and break easily. Due to this, the fire is readily extinguished.

A Simple List of Essential Chimney Products

Your chimney is crucial to making your fireplace safe and enjoyable. With a little effort and a few essential chimney products, you can make sure your chimney works safely and efficiently all season long.


Keep the Hot Stuff In and the Wet Stuff Out
A chimney cap is an essential part of your chimney. A properly installed chimney cap will keep sparks and embers from flying out of your chimney. A chimney cap will also keep rain from entering your chimney. Water that mixes with chimney residue can create acid slurry that will weaken the interior of your chimney.

Air: A Fire’s Best Friend
A poorly performing chimney can lead to smoke and harmful indoor air pollution. A ventilation van can increase the efficiency of your chimney, leading to safer, cleaner burning fires.

Shrug Off the Elements
Chimney flashing is a flexible metal shield placed around your chimney where it meets the roof. Chimney flashing is important to avoid leaks around your chimney. Flashing is available in kits or can be custom crafted at metal fabrication shops.

Keep Your Chimney Safe
Made of tile, concrete or metal, a chimney liner is crucial for keeping your chimney in safe working order. A chimney liner keeps smoke, heat and toxic gasses from entering your home. Flexible metal liners are available as replacement or retrofit items.

Avoid a Drafty Chimney
When not in use, a chimney should be closed with a damper to avoid drafts and heat loss. A top sealing tamper installed at the top of your chimney can provide a weatherproof barrier when you’re not burning a fire.

Clean Chimney Tools
Although your chimney should be professionally cleaned and inspected annually, cleaning it yourself is a great way to keep your chimney safe. Flue brushes can clean the inside of your chimney and are available in round, square or rectangular shapes. Some manufacturers also sell fire logs that break sticky creosote down and make it easier to sweep.

Why Homes Need a Chimney Liner

Written By The Staff of Rockford Chimney Supply http://rockfordchimneysupply.com/
With winter in full swing and the temperature dropping, many Home Owners will begin utilizing their chimney. It is important to make sure it is safe and will work efficiently. If your chimney was built in the past 50 years, you will most likely need a chimney liner. Even some “newer” models of chimneys could use one. This piece will talk about what a chimney liner is and why you would need one for your chimney.
What is a chimney liner?
A chimney liner is metal tubing that simply goes inside of the flue of the chimney and acts like a chimney within a chimney. There are two different liners: rigid and flexible both being made out of stainless steel. The majority of chimney liners on the market today resemble a dryer vent hose, but the Rock Flex brand of chimney liners are the exception to the rule.
If you are looking for the Cadillac of chimney liners then the Rock-Flex is the way to go. The design of your chimney will depend on which liner you would choose. If your flue is a straight shot to your fireplace then you could use either a flexible or rigid flue liner. If you have bends or it is not a straight shot then using a flexible chimney liner is the way to go.
A chimney liner can attach to any heating source that is being vented through your chimney including fireplace inserts, regular fireplaces, furnaces, and other heating appliances. Chimney liners are good with most heating fuels including wood, gas, and oil. If you are heating your home with coal or pellet, depending on your configuration in your home, we would recommend either a combination of a chimney liner and a Class A chimney system such as DuraTech.
Chimney liners are becoming required in most home sales and home inspectors are suggesting that they have them put in to make code.
So why would you need a chimney liner in your Home?
Masonry chimneys are typically lined with clay tiles to prevent buildup; however, over time they can crack and develop creosote buildup. This cracking can be contributed to the moisture getting into the masonry joints and expanding and contracting with the temperature . Creosote is a carbon by product from burning wood and other fuels. It can buildup over time and these gooey looking flammable deposits can cause a chimney fire that could devastate your home and property.
Installing a chimney liner in your home helps to protect from creosote build up by funneling the smoke from your heating source through your chimney creating a barrier between your flue tiles and the smoke. By insulating the chimney liner, the creosote has a harder time of building up since the liner stays warmer longer which in turn keeps the creosote from building up in the cold air. Tiles that are missing or even have small cracks create areas where creosote can build up and become a hazard.
Some chimneys are built without a clay lining, in which case they would definitely be candidates for a chimney lining system. The biggest reason why you need to have a chimney liner installed is to extend the life of your chimney. Overtime your masonry chimney will deteriorate from the intense heat and just general usage. By having a chimney liner installed, you extend the life of your masonry chimney.
What is the cost of a chimney liner?
If you have a chimney sweep install a chimney liner it could cost you thousands of dollars. There is an alternative that many DIY homeowners are taking advantage of which are DIY chimney liners. DIY chimney liners are a fraction of the cost depending on the length of your chimney and are easy to install. The only company out there that offers a lifetime warranty to DIY homeowners and carries a UL listed chimney liner is Rockford Chimney Supply. A chimney liner is well worth the investment of time and money.

2009 Winter Heating Tips From Rockford Chimney Supply

We Ship To The World.

Cold weather has finally descended on us, and fire departments are gearing up for what some in the fire service say could be a busy season. The heating season inevitably leads to problems — from chimney fires to malfunctioning furnaces that cause carbon monoxide buildup in the home. Rockford Chimney Supply President Brad White, said because it’s been so mild so far this winter, the fire season has yet to begin. But when it does, he said, many are expecting a jump in the number of calls for chimney and fireplace products, partly because of the downturn in the economy.

“Sometimes it’s a decision whether to eat or clean the chimney or maintenance the furnace,” White said. “Fire calls are way down from last year. We expect a difficult year when the cold weather does come in. Every winter we expect there will be heating system malfunctions. This season we expect more.”

In the two months after Thanksgiving last year, the U.S. Fire Administration reported one of the deadliest seasons in recent memory, with more than 150 residential fires nationwide that resulted in more than 200 deaths.Home heating equipment is among the top causes of fires and carbon monoxide poisonings.From 2003 through 2005, there was an annual average of 57,300 fires and 270 fire deaths associated with portable heaters, central heating systems and fireplaces and chimneys. There alsoare 68 deaths, on average, from carbon monoxide poisoning each year associated with home heating sources, the U.S. Fire Administration
reports.

Chimney fires, the burning of creosote clinging to the sides of a chimney’s liner, sometimes lead to house fires. Brad White, owner of Rockford Chimney Supply, recommends oversized caps for the top of the chimney to prevent water and animals from getting in the flue. A cap also works as a spark arrester. He said annual inspections can turn up everything from squirrels and birds to evidence of an unseen chimney fire. Because of their intense heat, White said chimney fires lead to cracked tile liners and other problems.“The tiles can’t withstand the sudden heat,” White said. “It can get up to 2,000 degrees.” In a fast-burning chimney fire, White said people have compared the sound to a freight train, jet engine or Mack truck.

White said "the risk of carbon monoxide poisoning is greater during the winter." Furnace malfunctions can lead to an increase in carbon monoxide in the home. Hundreds die and thousands of others suffer dizziness and nausea from the odorless gas that can be emitted from furnaces, gas kitchen ranges and kerosene space heaters if they are not properly ventilated. Signs of carbon monoxide poisoning include headaches, mental confusion and extreme tiredness. Whether it’s a wood stove, furnace or space heater, Rockford Chimney Supply recommends inspecting your systems and chimney's annually to alleviate any safety concerns. “Make sure the smoke and CO (carbon monoxide) detectors are up to snuff. It’s dollars versus life safety,” he said. “Most of the time oil companies have service departments that can at least take a look at the furnace.”

“White also recommends if your burning wood, you should especially be diligent an annual inspection,”. The amount of creosote buildup depends on how often a household burns and what type of wood is used. “Wet wood with higher moisture content leads to lower burning temperatures and more creosote. You want to burn good seasoned hardwood — oak, maple, ash. Stay away from things like pine and hemlock,” White said. After many years in the business, White said he finds people scrimp more on the structural issues — the bricks and mortar of a chimney. While it is important to have the liner looked at and cleaned, cracks in the brick or gaps in the mortar can lead to house fires.

Winter fire prevention Inspect each year of all fuel-burning home heating systems, including furnaces, boilers, fireplaces, wood stoves, water heaters, chimneys, flues and vents. Take precautions when using space heaters, fireplaces or other heating sources to help stay warm this winter.Install smoke alarms and carbon monoxide alarms in the home and check that the batteries are fresh and working.

Place space heaters on a level, hard and nonflammable surface (such as a ceramic tile floor), not on rugs or carpets or near bedding or drapes. Keep the heater at least 3 feet from bedding, drapes, furniture and other flammable materials. Keep children and pets away from space heaters.To prevent the risk of fire, never leave a space heater on when you go to sleep or place a space heater close to any sleeping person. Turn the heater off if you leave the area. Never use gasoline in a kerosene space heater. Even small amounts of gasoline mixed with kerosene can increase the risk of a fire.

Use a space heater that has been tested to the latest safety standards and certified by a nationally recognized testing laboratory. These heaters will have the most up-to-date safety features; older space heaters may not meet the newer safety standards. An unvented gas space heater that meets current safety standards will shut off if oxygen levels fall too low.Do not use portable propane space heaters indoors or in any confined space unless they are specifically designed for indoor use. Always follow the manufacturer’s directions for proper use.

Inspect flues and chimneys for leaks and blockage by creosote or debris.Open the fireplace damper before lighting a fire and keep it open until the ashes are cool. An open damper may help prevent buildup of poisonous gases inside the home.Store fireplace ashes in a fire-resistant container and cover it with a lid. Keep the container outdoors and away from combustibles. You need to consider a chimney liner stainless steel if your chimney is oversized.

Never use electric or gas stoves to heat the home. They are not intended for that purpose and can cause fires and carbon monoxide poisoning.
