Gas Furnace Chimney Liner


When thinking about a gas furnace and venting it into your chimney you should really consider relining your chimney with a stainless steel chimney liner. Why? Today’s furnaces know how to break down masonry chimneys. It’s what they do. They find ways to make block crumble and create issues for your home. Some will say to reline the chimney with an aluminum chimney liner. You can, but plan on replacing it within 10-15 years. Aluminum chimney liners simply don’t last. If they don’t last they can break down and even create blockages in your chimney. If this happens, the toxic flue gases that are supposed to go outside your home can end up inside. People have died from this, it’s nothing to play games with. If you want the best and safest chimney, reline your chimney with a Flex King Stainless Steel Chimney Liner.

Rigid Chimney Liner


Rigid chimney liner is the best chimney liner you can use. The only thing is you must have a straight masonry chimney flue. If your chimney flue is not straight and has offsets, installing a rigid chimney liner is not your best bet. Most likely you will not be able to install this type of chimney liner. If your chimney has offsets then you will need to use a flexible chimney liner.

Rigid chimney liner is smooth like glass. This will make it so creosote will not stick to the sides of the chimney liner like traditional corrugated flexible chimney liner. Chimney Liner Depot has the best rigid chimney liner available. Give us a call and we will help you figure out if rigid chimney liner will work for your chimney relining project.

Chimney Repair – Flash Seal


Every chimney is susceptible to water damage. If you have not repaired your chimney yet, the day will come. All chimneys need regular servicing. Chimneys are always outside subject to all the elements. Take a look at this video to see how you can repair the area of the chimney where it goes through the roof.

Chimney Caps


What is a Chimney Cap?
A chimney cap is a protective covering which fits at the top of your chimney enclosure. They are typically fashioned out of stainless steel, copper, or galvanized metals; and come designed with a mesh screen to inhibit airborne hearth sparks, nesting outdoor animals, and damaging precipitation and debris from interfering with the overall safety and longetivity of your fireplace’s necessary venting system.

Why is it so crucial to keep sparks confined to your chimney and these other elements out? While you are toasting marshmallows and sharing intimate discussions by the glow of your fireplace’s hearth, quite a bit more is happening in the venting chamber of your chimney. The sparks produced from burning wood or faux logs will sometimes reach to your chimney’s top, and if not properly stopped, can ignite the flammable material surrounding your chimney wall, such as your roof and house’s construction. And all it takes is one airborne spark. Nesting animals such as squirrels and birds can find a sheltered refuge in your chimney’s top, usually without anyone being the wiser…until it’s too late. A chimney cap prevents them and their detrimental waste from taking up residence, thereby preventing foul odors and the mites that waste brings. Your chimney top is also exposed to rain, snow, hail, and violent gusts of wind; year after year. Without a chimney cap to insulate your chimney from its effects, rain can soak into the mortar joints of your chimney’s construction, thereby loosening the bricks or stone of your masonry chimney. Or if you have a metal chimney, precipitation will lead to damaging rust; thereby rapidly deteriorating your chimney. Violent wind gusts whip leaves and assorted debris into your chimney. These flammable materials can rapidly suffocate your flue from its necessary fire by-product venting, leading to dangerous chimney fires and downdrafting of the trapped smoke into your home. Buying a chimney cap is a priceless and easy solution to preventing a whole Pandora’s Box-full of natural evils, such as: fire, disease, costly repair, and strife from entering the safe harbor of your family’s cozy home.

Types of Chimneys
The first step in finding yourself a chimney cap is determining what type of chimney your house has. This will determine what type of chimney cap will fit best. The most common type of chimney is a masonry chimney, which is constructed of brick, stone, or concrete. Metal Chimneys or factory-built chimneys are mass-produced, typically come with a pre-fit chimney cap, and must be used with one, due to the fact that metal is less resilient in relation to Mother Nature’s elements. Typically, for masonry chimneys, you’ll find that their corresponding chimney caps come in three basic sizes: 8″ x 8″, 8″ x 12″ and 12″ x 12″, though custom styles and fits are available also.

Types of Flues
Whether you have a masonry or factory-made metal chimney, it is also necessary to determine what type of flue it works from. This can be determined by simply looking down into your chimney’s depths.
Masonry chimneys will have either single or multi flues, and these flues will be either extended or not. The most common is the single flue chimney with an extended flue. This flue will simply and visibly extend out the top of your chimney, allowing easy chimney cap installation and fit by screws which tighten to the flue’s construction. Single flue chimneys without extended flues have a recessed interior flue construction and will require what is called a leg kit or bracket to for installation of your chimney cap. The decision about whether you enlist a leg kit or brackets is yours, but brackets are recommended as they provide more resiliency under varying wind and weather conditions. Multi flue chimneys with or without extended flues will, as the type suggests, have more than one flue (typically two) either protruding from your chimney top or recessed in its interior.

Factory-produced Metal Chimney will have one of three basic types of flue construction: double-wall solid-pack insulated chimney pipe, double-wall air-insulated chimney pipe, or triple-wall air-insulated chimney pipe. Looking down into the chimney, you’ll see either two or three layers or walls of metal. If there is a metal cap or insulation material between these layers, you have yourself a solid-pack insulated flue system. If there is nothing but air between your flue walls, it is an air-insulated flue system.

After determining what type of chimney and what type of flue you have, the next step is measurement of the flue system. Whether single or multi, extended or recessed, you will almost always need to know the precise width and length dimensions in order to accurately fit your chimney for a cap. Take the measurements a couple times to ensure accuracy, because being just a fraction of a size off, will negate all the purposes you’ve enlisted your chimney cap to demonstrate.

Masonry Chimneys:·For a single flue with an extended flue: measure the width and length of the outside parameters of the flue, and match these to a specific chimney cap size.·For a single flue without an extended flue: measure the width and length of the inside parameters of the flue, match to a specific chimney cap size, and order the corresponding leg kit or brackets.·For multi flue systems with or without extended flues: measure the total outside width and length of the combined flues. If your multi-flue system has one or more extended flues, you must next measure how far the highest flue extends out the top of the chimney. It is crucial when choosing a cap for these systems that you depend upon the measurements of your total flue system, as well as the flues’ height measurements to see how deep your chimney cap should be.

Factory-made Metal Chimneys:·For a double-wall solid-pack insulated flue system: measure the diameter of the inner pipe. Then, measure the diameter of the outer pipe. The inner dimensions will be used to secure the proper fit, while the outer dimensions will give a wider secondary cap protection for your flue. ·For a double or triple-wall air insulated flue system: measure the diameter of the inner pipe. Then, measure the diameter of the outer pipe. The inner dimensions will be used to secure the proper fit, while the outer dimensions will give a wider secondary cap protection for your flue.

Chimney caps come in a variety of materials depending on your aesthetic, function, and cost preferences. Galvanized metal flue caps are the most cost-effective and simple choice; but provide basic function without regard to aesthetics, will rust, and won’t last past the short-term. Stainless steel chimney cap construction is more middle-of-the-road cost-wise, and subsequently offers a more gratifying visual appeal, and will last much longer through varying elements and time. Copper chimney caps are the most expensive choice, but because of this offer: a hard-enduring quality, can be weathered naturally or coated with a special copper protectant to maintain the original color and shine. Stainless steel and copper constructed chimney caps do, more often than not, come with an extended warranty; and are the best way to go in the way of your chimney’s longetivity and your home and family’s safety.

Chimney Cap Types
Chimney caps also come in a variety of functions according to your cap preferences. There is the standard chimney cap which typically includes a screening material to further ward off elements and critters, is the most cost-effective, comes in a variety of materials, and takes care of your most basic chimney needs as far as insulation and protection is concerned. Draft increasing caps or vacuum chimney caps are more specific to a chimney that has difficulty, for one reason or another, drafting smoke up and out of your home. These chimney caps produce a stronger updraft, and are most often used with metal chimneys, though those with masonry chimneys can employ specific manufacturer adapters. There are two different options to cure this common chimney affliction. You can either employ what is called a flue stretcher which will extend the length of your flue and remove it from the influence of nearby or dual chimneys. This is a great option if you live in a dense city or have multi-floor fireplaces. Another option is a device which will decrease the downdraft by deflecting it within special cap fins, and subsequently suck excessive smoke out of your chimney. You may opt for a cap with an integral damper mechanism to replace a missing or loose-fitting damper system in your chimney. This type of chimney cap, once in place, will cap the previously wasted energy, restore the necessary damper functions, and insulate your home from the elements. Most come complete with a lever you’ll need to install on your fireplace wall, which activates effective use of the damper. Typically, those with older fireplaces will enlist these dual-purpose caps to gently restore an older fireplace.

Chimney Chase Cover


Chimney Chase Cover

Have you noticed over the years a rust colored stain coming from the top of your chimney? This stain is not from your chimney but is in fact from your chase cover.

Where Can I Buy a Chimney Chase Cover?

chimney chase coverOver time almost all pre-fab chimney chase covers rust due to the elements. Snow, ice and rain gets trapped on top of your chase cover and starts the decaying process. Leaves and pine straw also mixed with the moisture creates an acidic condition and breaks down the galvanized coating of your chase cover.

When this breakdown occurs the chase cover begins to pit. This will allow water to drip inside your chimney. Let this rust stain be your sign that it is time to replace your chase cover.

It is recommended when replacing your chase cover to use stainless steel. Stainless steel is more durable, stronger and will look new for a longer period of time. It is also recommended that the chase cover be designed with a cross break which creates a “dome” effect. This will prevent the snow, ice and water from pooling on top of your chase cover. Stainless chase covers come with a lifetime guarantee against rust and corrosion.


Rigid Chimney Liner


If you are considering relining your chimney with a stainless steel chimney liner, you should definitely consider installing a rigid chimney liner.

304L is for venting wood appliances. 316L is for venting wood, coal, oil, and gas burning appliances.Most rigid chimney liner sections are made of nonmagnetic, series 304L or series 316L stainless steel. Unlike the flexible stainless steel liner, rigid pipe comes in sections and is usually round in shape and one to four feet long and five to ten inches or more in diameter. The most common wall thickness is 24-gauge (0.024 in.) or 22-gauge (0.029 in.) stainless steel.


Stainless Chimney Liners Can Save Lives


Here is a video from our local news station in Northeastern PA. An unfortunate event took place a few weeks ago. A problem with a chimney cost some folks their lives. After an investigation it was determined that an aluminum liner had deteriorated and clogged up the family’s chimney. Carbon Dioxide silently killed 3 people.

Is it to early to thinking about your heating system?


It’s only the 15th of July, there is plenty of summer left! This is true, but Fall is just around the corner. If you are thinking about relining your chimney, or are planning to utilize your old fireplace by installing a fireplace insert, now is the time to think about a chimney liner.

For some odd reason as humans we like to procrastinate. If it’s summer we don’t like to think about heating our homes. The problem is, when we wait until the last minute things always get complicated. Right now prices are low on chimney liners. As with everything, when demand goes up, prices go up. Stainless steel prices are on the rise as well.

We can’t stress it enough.  Now is the time to purchase a chimney liner. Give us a call and we will make the process as simple as possible.

An Overlooked Component

chimney exterior

If you’re like most homeowners, you don’t give much thought to your chimney. Unlike other things like your refrigerator, stove, heating system—it doesn’t make noise and doesn’t seem to require any attention. You may be aware that it needs to be cleaned periodically, but do you know how often? What does a proper, thorough cleaning consist of? Why should you be alert to deterioration, and how does it happen?

Home fires caused by malfunctioning chimneys are a reality. Health threats caused by leaking chimneys emitting dangerous gasses are also a danger. Your family’s safety and indeed their lives may be in jeopardy if you neglect this vital part of your home.

A chimney is not just a brick or stone contraption attached to your house. It has several different components and features that make it function properly. By design, it must be a certain height to provide “draw”. It will usually consist of a fascia, or outside structure that is the part you see. It could be brick or stone, and is designed to compliment your home’s exterior. Inside that fascia, is a liner. The liner is generally terracotta. Terracotta is red ceramic clay that will withstand high heat and is a good material for lining a chimney.

Terracotta liner comes in sections, with mortar between the joints. You may already be starting to understand that so many components can also mean increased potential for deterioration, wear, and ultimately failure of this important system. That’s not good.

You might liken your chimney to your car’s exhaust system. The exhaust system in a car is designed to move the byproduct of combustion out of the engine and safely dispel it into the atmosphere. You are probably aware that your exhaust system is subject to corrosion and in time it fails. You must then replace it. Your chimney does the same thing—it moves the byproducts of combustion out of your heating system and expels them into the atmosphere. A leaking, deteriorated chimney can be a real hazard. Why is that?

The by-products of combustion in your heating system produce smoke. This rises in your chimney and cools as it nears the top. What is also occurring near the top 1/3 of your chimney is very hot air colliding with cold air. This causes condensation. Water from condensation mixing with

Deterioration of chimney liner

deposits on your chimney wall called creosote will form an acidic substance that eats away at your terracotta and the mortar between the joints. As crumbling and breakage begins to occur, the same condensation starts collecting in the voids. It may freeze and cause more cracking. You should be getting the picture by now.

You can appreciate the dynamics even more if you think of your house as a breathing creature. It may sound strange, but your house is constantly drawing air in and pushing it out. As hot air rises in your building, cold air is being drawn in from below. It will come in through cracks around doors and windows, from the space behind outlets—just about anywhere there’s an opening. Your chimney is doing the same thing. Hot air rising to the top actually creates a “pull”, drawing cold air from the bottom. This pulling action is called draft. Think of drinking from a straw.

chimney fire

Chimney fire

So, here you have this constant force pumping air up through your chimney. Condensation is forming. Deposits are sticking to the walls of your liner. It’s becoming acidic and eating into the terracotta and the mortar. Don’t think YOUR heating system is immune—it happens with all heat sources.  The end result could be a chimney fire and a house fire.

If you’re using an alternate heat source such as wood, you should be aware that the risk is even greater for creosote build up and deterioration.

Don't let this happen to your home

    *Note: If you have a terra cotta clay chimney
    flue lining, be sure to measure the true length and width of the
    inside of your chimney flue space.

    *If there is a terra cotta clay flue liner, does it protrude out of
    the top of the chimney at least 2 inches? If there are at least 2
    inches and the terra cotta clay is in good condition, you will use
    our stainless steel, terra cotta top plate that has a 1 1⁄2inch edge
    that goes all the way around (like a shoebox lid).

    *If your terra cotta clay flue is in bad shape at the top, you may
    need to just take a hammer and tap all around that terra cotta,
    taking it away to make the surface flat at the top of your chimney.
    In that case, you will simply use the flat top plate that comes with
    our liner kit.

    *Note: If you have a terra cotta clay chimney
    flue lining, be sure to measure the true length and width of the
    inside of your chimney flue space.

    *If it is on the back of the stove, is it parallel with the back of the stove or is it at an angle, like 45 degrees?

    *If it is at an angle you will use an insert stove adaptor (an insert liner kit) rather than a two-part tee with cleanout cap.

    Usually pellet stoves have an exhaust hole id of 3 inches. However, if you are going up more than 15 feet to the top of your chimney you need to use a pipe and/or flex liner that is 4 inches diameter.

    If you are only venting a hot water heater then the exhaust hole diameter is probably 3 inch diameter. If it is 3 inch diameter and you are going up more than 15 feet to the top of your chimney, you must use a 4 inch diameter flexible liner or ridged pipe for proper draft. We also suggest to go ahead and use a 4 inch diameter flexible liner or ridged pipe even if the total length is 15 feet or less.

    Not the depth or any other dimension inside your fireplace.
    Most gas log fireplaces require an 8 inch liner kit or rigid kit. But do not assume that is the case for the gas log fireplace kit you are installing. Obey the requirements for that specific unit that are in your installation/instruction manual.
