I have a fireplace insert that has an 8" damper - flat against top of insert. Chimney needs to be lined, as it is currently not safe. The chimney will allow for a 6" pipe. I would like to remove the 8" damper and replace it with a collar, that reduces the entire opening to 6" with a 6" damper, what would I need?

Answer:Please note that you should never reduce the intended flue diameter for any wood burning stove or insert. Additionally, the stainless steel flexible liner must be insulated, meaning that you must allow room (1"+) inside the chimney for the insulation. If this is acceptable, please let us know and we will assist you further.

I am installing a HeetBlast 1500 wood burning furnace in my basement, which will utilize the duct work of my house propane furnace. I am going through the concrete basement wall to hook the 1500 up to the chimney which I plan on ordering from you. I will be more than 9" from the flamable floor joices where the thimble is installed. I already have the black single wall flue pipe. I plan on purchasing from you the double wall chimney pipe with a "T" at the bottom of the chimney pipe. I have been told triple wall chimney pipe is overkill, is this correct? Also, is this Security double-wall 6 inch black stovepipe to masonry chimney adaptor intended to be a thimble? I am getting a little caught up on nomenclature.

You will need to install 24 gauge sheet metal, spaced out 1" at the ceiling to reduce the single wall stovepipe clearance of 18" to 9". To answer your question, you will simply need to pass class A chimney through the concrete wall to the required distance (typically 6") into the room and will not need a thimble, if the wall is full masonry.
The product in question is for passing double wall stovepipe into a masonry chimney and would not be correct for your application. Please answer the questions asked on our Chimney Pipe Design & Quote Form
and you will receive a comprehensive list of components required for installation.

Does this Masonry Adaptor connect to the male or female end of stove pipe or is there another adapter required between the Masonry Adaptor and the stove pipe?
By eFireplaceStore on November 3, 2014
Answer:The masonry adapter will connect directly to the section of Security stovepipe before it without any other adapters required.

Will this work with double wall stainless stovepipe?
By Collin C. - NFI Master Hearth Professional on November 10, 2011
This product will only connect a masonry flue to Security brand, double wall black stovepipe. It is not designed to connect to a stainless, class A chimney, as the diameter is different. You can view an example of the Security stovepipe here:
Security Double-Wall 6-Inch Black Stovepipe - For Solid-Fuel Stoves
This type of pipe has a 6" clearance to combustibles and is the best choice for use in a home.

Can I install this adaptor into an existing 8-inch terracotta thimble? I have a VC Encore stove with 6-inch double wall pipe.

Answer:As this has an eight inch outer diameter, it will be a tight fit, but it should work for your application.

My home has an 8 inch masonry chimney and we are replacing the current wood stove with a new one that has a 6 inch vent. Is this Security Double-wall chimney adaptor what I need to go from the 6 inch pipe from the stove to the 8 inch hole in the wall that goes to the chimney?

Will this work? I'm trying to go from a 8 in masonry chimney to a 6in double wall. Does this slide in side or over masonry flue?
By Kevin E. - Fireplace Specialist on November 7, 2011
Answer:This adaptor is designed to be installed horizontally into a masonry flue. The smooth end should insert just enough to be flush with the inside surface of your masonry flue. Your black double wall pipe would then attach to the short side (black end in the picture).
