Round Stainless Steel Insert Boot
A round stainless steel insert boot is designed to make the connection from an insert between a square or rectangle flue outlet and a round chimney liner. Many old style fireplace inserts have a rectangle flue outlet. This is because at one time they believed it to be OK just to set the stove inside the fireplace and call it good. This is no longer the case. Now we know of the dangers caused by this type of install.
What size Insert Boot do I need?
Every stove needs a proper size chimney liner for proper draft. The square inches of the outlet on the stove needs to be as close as possible to the amount of square inches of the chimney liner. First, you measure the length and the width of the flue outlet on the stove (as seen in pic). Once you have your total square inches, you now know what size of insert boot you need.
Insert Boot Measurements
A round chimney liner is designed to be mechanically mounted to the insert boot. The insert boot will also need to be screwed to the top of the insert. You need to install an insert boot that will accept a chimney liner that can handle the same amount of square inches as the outlet on the stove. This means for example, if your measurements are 4″ x 9.5″, your total square inches are 38″. Now it is as simple as finding a chimney liner that will handle 38″ square inches.
- 6″ chimney liner is 28.3 sq. inches
- 7″ chimney liner is 38.5 sq. inches
- 8″ chimney liner is 50.3 sq. inches
In conclusion, you will simply use the above chart to discover what size chimney liner you need and what size round insert boot you may need also. One possibility that you may encounter is, on some stoves, the flue outlet is extra large. The average insert boot may not cover the flue outlet. Do not worry. Give us a call and we can make one to any size you need.

Why do you need a chimney liner?
You may ask, “Why do you need a chimney liner?”. You may think that your chimney has been there for almost a hundred years and as far as you know it is safe. So why is my chimney sweep telling me I need to install a chimney liner now?
Chimney liners are designed to keep the harmful gases of your furnace or creosote from the stove inside the chimney and keep them from entering your home. Many homes have a chimney with very old technology. They have terra cotta (clay) flue liners. They were designed to work with coal, they still do work for coal. But now very few people burn coal as a main heating source.
Why do you need a chimney liner if you are burning gas, oil or wood?
Today many people burn natural gas and home heating oil. The terra cotta flues were not designed to withstand the acids inside the exhaust. Wood burning stoves create creosote, that when hot, is a flammable liquid. This creosote can be seen in the picture leaking into the home. This is an extremely dangerous chimney. As you can see the flammable creosote is now entering into the home and can easily ignite, catching the home on fire. With gas and oil burning appliances, eventually the terra cotta deteriorates, creating he possibility of the chimney flues falling over inside the chimney. This will creat a blocked chimney, a very dangerous situation for your family.
You need a stainless steel chimney liner, it is what will stand up to the harsh exhaust from a modern furnace and the dangerous creosote from a wood stove.
