Will this match a Martin Industry 8 inch chimney section LF-3-1? My section has air space with three pipe section in one. Outside pipe measures approximately 13 inches and inside one is 8 inches with locking tabs.
By Collin C. - NFI Master Hearth Professional on February 27, 2012
Answer:While the remainder of Martin industries was purchased by Majestic, their proprietary chimney system was not carried over and is a slightly different diameter. The pipe also uses different locking tabs to attach.
Some installers have modified this Majestic pipe, as it is the closest thing available to the original Martin product, however I only recommend this if you have proper metal working tools to modify the connection. Otherwise, I would highly recommend checking with past dealers of Martin pipe to see if they still have any stock.

Can I replace my Duraplus 9219 triple wall with this chimney section? Will it be an exact match in size?
By Collin C. - NFI Master Hearth Professional on June 13, 2013
Answer:Unfortunately, no. Duraplus is a combination solid pack and air cooled chimney, which has an outer diameter of 12 inches.
This Majestic triple wall pipe would have the same inside diameter, but the middle liner is 11 inches, with the outer measuring slightly over 13. In additional, the Majestic chimney is fully air cooled and will not work the same as the Duraplus.

I have to extend two majestic triple wall chimney pipes for wood burning fireplaces on a home we are remodeling and will need a 3ft. section and a 4ft. section plus two storm collars and two caps. Will the newer pipes fit the 25 year old pipe that is there now? They are 13-1/2in.,11-1/2in. and 8-1/2in. outside diameter.
By Tyler M. - Fireplace Specialist on December 6, 2011
Answer:Unfortunately, this triple-wall pipe will not fit your pipe's dimensions. This pipe has an 8" inner diameter, with 11" and 13 1/8" outer diameters.

How do I separate sections of S type flue pipe once they have been snapped together?
By Chris C. on September 19, 2014
Answer:To disconnect the pipes from one another after installation requires patience so as to not damage the pipe and elbow grease. The snap lock connections are notoriously difficult to disassemble, but it can be done. A flat blade screw driver would assist in separating the pieces, but it is difficult to do without damaging the pipe itself.

Are these pipes flared to insert into each other as they extend up?
By Kevin E. - Fireplace Specialist on April 9, 2012
Answer:These pipes actually feature proprietary twist lock connections at the ends that allow them to attach to one another.

I just purchased a home with what I think is a Majestic wood burning fireplace (the name plate is un-readable), but it has a triple wall flue pipe on it. I need to extend the flue by about 12 feet for an addition I am adding and was wondering how to do this. The triple wall flue I have has the center pipe at about 8 inches in diameter, the middle pipe is about 11 inches and the outer is about 13.25 inches. Can you help?
By eFireplaceStore on September 16, 2014
Answer:The dimensions you provided are exactly correct for the Majestic type S triple wall chimney. As such, you can likely use the system we sell, as Majestic has not changed it in some time.

I have a Preway fireplace and chimney circa 1986, can I use the chimney on a Majestic 42" fireplace?
By Chris on March 10, 2014
Answer:I would ultimately advise against the use of Majestic chimney pipe with your Preway fireplace as the unit and chimney pipe were not tested and listed for use with one another.

I'm trying to find an 8" inner wall, 11" middle wall and 13" outer wall. Does this product have those measurements?
By Collin C. - NFI Master Hearth Professional on October 2, 2012
Answer:This item does indeed have an I.D. of 8". However the middle and outer walls are slightly larger at 11 3/8" and 13 3/8" respectively. Further, this triple-wall pipe is compatible to vent a Majestic or Monessen fireplace.
By Nicky from Las Cruces, NM on November 22, 2013
I have a circa 1979 Martin Industries LF-36 wood fireplace and want to install a QuadraFire Columbia Bay Gas insert into it. However the flu is only about 8 ft high and the Insert instructions (and code I assume) call for a minimum of a 10 foot vent. How hard is it to modify the Majestic pipe to get that last two feet at the top? Any other suggestions would be appreciated.
By Collin C. - NFI Master Hearth Professional on November 22, 2013
Answer:The Majestic vent pipe is generally the same diameter, but the lances are a bit different. The two systems can be made to work together, but I recommend fastening the sections together with sheet metal screws. This would be the only option to pursue, as we can no longer obtain the Martin pipe.
By Louis from Bixby, OK on October 3, 2016
Would this pipe be compatible with an old Preway fireplace with 8A piping?
By Will M. on October 4, 2016
Answer:This would not be compatible. Unfortunately, we will not offer any chimney that will be compatible with Preway fireplaces.
