Can this be "ovalized" and re-rounded to get through an existing damper in my fireplace that is 5" wide?
By Chris C. on March 2, 2015
Answer:This can indeed be field ovalized to fit through your damper, and then rounded back out to connect to the top of the appliance.

Which model is better, the 304- alloy, or the 316?
Also, I have a 20' length of 8" stainless steel flex already on hand. Could I put the 6" pipe inside of the 8" pipe which would be inside of a 11-1/4 x 11-1/4" clay tile chimney? If so, could I insulate between the 6" and 8" and between the 8" and existing flue liner?

Answer:The 304 alloy of stainless steel is the standard for wood burning. It offers good corrosion resistance and is lower cost. The 316 grade is a step up and can be used with wood, coal, and oil. It offers excellent corrosion resistance against all of these fuel types.
It is certainly possible to run the 6 inch liner within the 8 inch, but I would not worry with insulating both. Insulating only the 6 inch liner or the 8 inch will be more than sufficient.

Can this liner be used with a fireplace insert?

Is this item rated, or can it be used with a wood burner stove?
By Collin C. - NFI Master Hearth Professional on December 10, 2013
Answer:If you are venting the wood burning stove into a properly built masonry chimney, the liner can be used in the chimney to transition from single wall stovepipe.

I have a 6 and 5/26 inch inner diameter Suma clay chimney flue for my fireplace. Will this DuraFlex 6 inch diameter x 15 foot long kit chimney liner fit through? I am concerned about the sections of the flue that are slightly offset and I'm not sure if there are irregularities in the mortar.
By Will M. on October 12, 2015
The 6 5/16" dimension does not account for the mortar joints that are visible inside of your flue. While these joints should be smooth to prevent the buildup of creosote, they likely would prevent 6" diameter chimney liner from being installed. If this is an exterior chimney, local code may require this to be insulated and the 6" liner would definitely not work. I would consider Small HomeSaver Ovalflex
as the outer (oval) dimension is 4 3/4" x 10 5/8".
