I have a wood-burning stove (photo attached) and recently had the 30-year old chimney inspected. The inspector found significant damage to the chimney's existing clay liner and recommended having a stainless steel liner installed. I'm in agreement but have some questions. The chimney has an exterior clean-out door just above ground-level. The wood-stove exhaust pipe connects with the chimney about 57" above the hearth. My understanding is that the norm is for the chimney liner to stop at the bottom of a "Tee" where the stove pipe meets the flue/liner. This would appear to result in there being about a 50" high dead space in the chimney, from ground level to the bottom of the "Tee". Other than the expense, would there be any harm in extending the liner all the way to the bottom of the chimney, so I could continue to use the existing clean-out door? What are the pros and cons?

Answer:Your assumption about the installation is correct. There is indeed normally a tee at the level of the thimble. In the event that there is not direct access to the base of the tee, you can indeed extend the length of the run with additional liner and a coupler. The only issue that normally needs to be worked around is making sure the extension is as straight as possible so that any creosote or ash that falls closely enough to the clean out door that is can be vacuumed out.

I am converting a 6" wood burning Selkirk stovepipe to gas fireplace stovepipe. Can I put a liner down the pipe to convert it?
By eFireplaceStore on November 4, 2014
Answer:You can indeed reline the existing piping for use with a gas insert. However, there is not an adapter made for a co-linear 3 inch liner setup, if that is what you are doing. A custom enclosure may need to be made to hide the transition from liner to stovepipe.

I have a 12" x 8" brick chimney that goes directly into the basement with a 90 degree turn at the bottom through the basement concrete wall. What do I need to do to install a liner so I can hook up my wood burning boiler?
By Collin C. - NFI Master Hearth Professional on July 2, 2013
Answer:In order to make this conversion, the appropriate length of flexible liner, connection tee, support plate, clamps, and cap will be needed. A short run of single or double wall chimney connector will also be needed to span the gap from the appliance to the chimney thimble. However, you would need to know the distance from the top of the chimney to the existing thimble, before you make any purchases.

How do I convert from square clay tile to the Duraplus 6" triple wall pipe?
By Collin C. - NFI Master Hearth Professional on November 19, 2012
Answer:Making the change to a Duraplus chimney system would require a masonry transition plate, which is designed to be used in conjunction with the appropriate slip connector and flexible liner assembly.

I am getting ready to build a home and will put a wood burning stove in my basement connected to a masonry chimney, without a fireplace. What size of thimble should I install in order to be able to connect the liner to the stove pipe?
By Will M. on August 13, 2015
This will be dependent on the diameter of the stovepipe. The stovepipe and chimney should always remain the same diameter the length of the chimney run all the way to the termination. For passing single wall stovepipe through a masonry chimney to DuraLiner, a thimble is available in 6 inch
and 8 inch
diameter. For a detailed quote for all components that will be required, please answer the questions asked on our Chimney Pipe Design & Quote Form.

I need to line my wood burning masonry fireplace. How do I connect my stainless liner to the damper so there is not air leaking past the new 6" liner up the flue?

Do you have the complete chimney liner kits, including insulation? We need approximately 6" by 13 ft.
By Collin C. - NFI Master Hearth Professional on November 7, 2012
Answer:We do indeed offer complete liners kits for most needs. Will you be venting a wood-burning appliance or a unit that burns coal or oil? The type of alloy needed will depend on the fuel being used.
By Dave from Ottawa, CAN on October 5, 2014
I took out my oil furnace and replaced it with a different type that doesn't require venting. I would like to use the old chimney to vent a wood furnace. What needs to be done to ensure this is safe? Can I simply install a liner or is there more?
By eFireplaceStore on October 6, 2014
Answer:If the old chimney is a masonry chimney, you will indeed have to install a properly sized liner and insulation wrap. If the chimney is a prefabricated metal pipe, it may already be suitably sized for your new furnace.

I have an 8 x 8 clay chimney. I would like a 6" SS liner. Do I have to remove the clay tiles? Can I pour insulation around the SS liner?
By Tyler M. - Fireplace Specialist on February 12, 2013
No, your tiles can indeed stay in place; and yes, if the tiles are not cracked or damaged, you can use pour-down insulation to surround the liner. We recommend the HomeSaver Insulation Mix

Where can I find a flex liner for a 6 inch chimney for my wood stove?
By Kevin E. on December 9, 2014
If your venting is routed through an existing masonry flue, it would be acceptable to utilize flex liner to vent the stove. Depending on the height of your flue, something like our 6" x 25" Homesaver kit
might work fine for you. Of course, you'll likely also need a component kit
to complete installation.

I'm installing an insert in a fireplace where it already has double wall straight steel pipe 12" and 8". Do I need the 6" flex liner pipe?
on November 9, 2012
Yes, you will need 6" stainless steel liner to vent our wood-burning inserts. Please note that you need to make sure that your existing fireplace is listed to accept the particular model that interests you, and that the insert itself is able to be installed in a manufactured fireplace. You can see one example of our 6" stainless steel liner insert kits here:

Can you put a liner in a triple wall metal chimney?
By Collin C. - NFI Master Hearth Professional on August 9, 2013
Answer:Certainly. As long as the triple wall chimney is in good condition, it can house a liner to size down the flue for an insert or stove.

I am installing a pellet stove where a wood-burning stove was, and I need a 3 inch 30 foot chimney liner. What would be recommended? Do I also need a vent kit or does the liner suffice?
