In most cases, you will need to install a chimney liner if your chimney has an over-sized or deteriorated terra cotta (clay) liner. You must always install a liner if you have an unlined masonry chimney. Both the National Fuel Gas Code (NFPA 54) and the national Installation of Oil-Burning Equipment code (NFPA 31) compel installations of the chimney liner in these circumstances. boilers have increased in efficiency, the temperature of the flues gases has declined.

After you have properly pitch your tipi, you have a tent open at the top and all around the bottom. Since the cover is a few inches off the ground, as it should be, a considerable draft is possible making the tipi nothing more than a temporary shelter, not really fit for living in. Winds blow across the bottom of the tipi making the tipi drafty and cold and raindrops run down the poles and soak everything inside. See similar questions...

The National Fire Protection Association (NFPA) Standard 211 requires that chimney liners be replaced if they are cracked, broken, or missing. Cracked clay liner tiles and the deterioration of mortar joints between liner tiles can lead to the leakage of flue gasses into the interior of the house. Those flue gasses contain Carbon Monoxide, a deadly, odorless, colorless gas. Cracks in your chimney liner can also cause dangerous heat transfer to combustible material surrounding your chimney.

It is strongly advised that you do insulate. When you install your liner with the proper insulation we carry, your reline job achieves the UL Listing of 1777 Standard, which your insurance company will love. Besides, an insulated chimney has a better draft and stays cleaner longer. See similar questions...

Currently, most masonry chimneys are built with terra-cotta clay tiles stacked and mortared inside the brick structure. These tiles serve as a gas-tight and heat-resistant insulator against the masonry structure. Without a liner, or with cracked and damaged liners, there would be heat transfer or actual seepage through the brick and mortar. A liner is a stainless steel tube inserted into a chimney to draft an furnace, woodstove or fireplace. See similar questions...

The chimney flue should be the same size as the appliance flue collar. In the past, many chimneys were too large for the appliance they served. But bigger is not better when it comes to chimney size. Flue gas flows faster and has less time to lose heat in a smaller chimney flue. In planning wood-heating systems, some experienced installers even choose a chimney that has a smaller inside diameter than the appliance flue collar. See similar questions...

You can have it inspected by a chimney professional; or, if you're able, you can go up on the roof and check it out yourself. If you look down into your chimney and see only bricks and no clay tile, it is not lined. Some chimney professionals who inspect your chimney can actually lower a video camera into the flue and either show you their findings on a monitor as they are inspecting your flue, or make a video tape and play it back for you later.

If you are relining a fireplace chimney, you will most likely be able to pull the liner up the chimney with a "Nose Cone" and a rope, but it is usually much easier to let gravity help you and install the liner from above. When installing a liner in a standard chimney that has a thimble in the wall; you cannot install the liner from below because it would not make the 90 degree bend to go up the chimney.

Depending on the type of chimney you have your chimney sweep may recommend either a rigid or flexible pipe. There are many scenarios and options in relining a chimney depending on your situation.

There are many online chimney liner stores who will tell you that installing a chimney liner is easy. They tell you that anyone with common sense can do it. They are right.

That requires a thorough inspection. This is a case where a chimney professional would most likely use a video inspection system of some kind so he could systematically inspect every tile in your chimney's flue. Such an inspection will be able to show any cracks, even small ones, in your chimney tiles and/or any damage to the mortar between the clay chimney tiles. Once again, you could then view the results of that video inspection yourself. See similar questions...

Yes they do! But as a matter of fact, we encourage you to download the installation instructions from our website before you buy any reline product. Look on the page of the liner you are interested in and you will find a link to the instructions for that product. See similar questions...

The purpose of the chimney structure is to prevent the warm buoyant air inside the chimney from mixing with the surrounding cooler ambient air outside the chimney via entrainment. Without the chimney, the warm rising air from the solar collector would quickly mix with the ambient air which would rapidly reduce its buoyancy. The maximum efficiency of a solar chimney is proportional to its height; the taller the chimney, the more work can be captured by the turbine. See similar questions...

Chimney caps provide protection from water intrusion damage, animal entry, spark escape (spark arrester), down drafts, etc. Much like the sidewalk & street, water intrusion with expansion & contraction causes cracks. This is undesirable in the firewalls of your chimney. See similar questions...
