Chimney Liner FAQ

Answers to all your questions regarding Liner Installations, Liner Types and so much more.

#1 Are your Champion Chimney Liners UL tested?

Absolutely! While there are many companies that sell liners, only a handful have gone through the process of being tested and passing the strict UL Listing codes. Champion Liners are UL/ULC Listed and meet all UL1777 and ULC-S640 code specifications. These professional-grade liners are guaranteed to last a lifetime. The warranty is also transferable to the next homeowner. Champion Liner's UL/ULC status is why we offer them today. These liners have proved to be the very best available.

#2 Why would someone reline their chimney?

Chimney liners are used in most new masonry applications, as well as in remodels. Two of the most common uses for relining a chimney are to bypass older, damaged or irreparable chimneys, or to vent a new heating appliance such as a pellet or wood burning stove through an existing chimney. Chimneys without a clay liner can be made safer by installing a stainless steel liner.

#3 Are chimney liners better than traditional masonry chimneys?

Typically yes. Chimney liners offer three major advantages. First, they last considerably longer. Champion Liners boast a lifetime warranty. Secondly, they are typically easier to clean. The smooth-walled liners make it difficult for creosote to adhere to the inside of the chimney. Lastly, chimney liners maintain a hotter core, boosting your operating draft. In other words, there is less smoke backing up into your home.

#4 Can I reline my chimney myself?

Absolutely. If you are a handy individual, and if you allow us to help you along the way, you should have no problem relining your chimney.

#5 Are some liners easier to install than others?

There are three types of liners: Easy-Flex, Heavy-Flex and Rigid. More than 85% of all relines are completed using an Easy-Flex liner because it is light weight and requires no special lifting tools. The Champion Easy-Flex Liner carries the same lifetime warranty as the other liners available. Although the Champion liners are designed with ease of installation in mind, it is always recommended to have help when installing flexible liners. When installing a Heavy-Flex liner, more than one person is mandatory for installation.

#6 Are any special tools required when installing the chimney liner?

Not usually. The basic installation tools vary depending on which liner is being installed. For example, liner gloves, an extension nut driver, crimper, caulk gun, pop-rivet gun (for rigid pipe), liner snips, etc.

#7 Why is the “Heavy-Flex” liner more difficult to install than the “Easy-Flex” liner?

The Easy-Flex liner is light weight where one person could lift a 30-foot roll with one hand. The Heavy-Flex liner is heavier where a 30-foot roll could weigh 100 lbs. There are two ways to install the Heavy-Flex liner:

  • Top-Down, through the chimney opening. What makes this difficult is getting the large heavy unit up on the roof. Using a lift could make the process significantly easier.
  • Bottom-Up, through the fireplace opening. For this method, a chimney mount winch would be rented. The cable would be dropped through the chimney opening down to the inside of the fireplace. The cable would be attached to the liner and the winch would be cranked, pulling the liner up the chimney. This process is more common; however, we would recommend using one of our pulling-nose cones for ease of installation. The pulling-nose cone is tapered in the front to lessen the possibility of the liner getting caught on anything inside the chimney.

#8 How should I measure for my liner length?

The best way to measure for chimney liner is to measure from the top of the chimney to either the center of your firebox or to the tee or thimble area where your appliance or stove will connect to the chimney. It is suggested to add an additional foot or two so your liner doesn't run short.

#9 How do I measure for the chimney liner diameter?

Measuring for your chimney liner diameter is more important than most people realize. If the liner diameter is too small, it will not draft properly and will lead to a smoky room. If the liner diameter is too large, the fireplace or heating appliance will lose its efficiency and must of your heat will go up and out of the chimney. We understand the functional importance of a properly measured chimney liner diameter. Woodland Direct, has gone to great lengths to help you accurately size your liner. There are two ways to accurately size your chimney liner:

  • Call one of our experienced chimney experts at 800-919-1904.
  • Examine your chimney to make sure the recommended liner size will fit inside the flue. If it will not, you may need an equivalent oval or rectangular size to keep the same amount of draft without choking off the flow.

#10 Do I need to insulate my chimney liner?

Absolutely. You should insulate your chimney liner for the following reasons:

  • In most states, insulating your chimney liner is required by code.
  • Keeping the chimney warm will greatly enhance its draft ability.
  • Insulated chimneys greatly reduce condensation, which ages metal chimneys and must be drained.
  • A warm, less condensing chimney would create less creosote built-up and/or corrosive material build-up. With less build-up, the chimney is significantly easier to clean, maintain and last a lifetime.
