Stovepipe Oval to Round Boot Stove Connector
December 1, 2014
This product arrived promptly in the mail. I took the product to my cabin and installed it on my antique wood stove. The oval to 6" round connector fit perfectly. Now I can heat my cabin with wood instead of propane.
Great quality at a fair price!

By Bob from Kingsley, MI on October 9, 2014
What is the width of this adapter at the oval?
By eFireplaceStore on October 9, 2014

The oval end of this adapter is 8 1/4 inches in width by 6 3/16 inches in depth.

Does this item come in 8 inch oval to round?
By Tyler M. - Fireplace Specialist on November 7, 2011

No, unfortunately it only comes in the 6" inner diameter.

By "Mary" from "Astor, FL" on December 3, 2011
What is the size of the oval?
By Kevin E. - Fireplace Specialist on December 5, 2011

This adaptor features an oval measurement of 7" x 6".

By Catherine Ragonese from Ft. Pierce, FL on July 15, 2012
Will this work for a wood stove?
By Tyler M. - Fireplace Specialist on July 16, 2012

Yes, but please note that the oval end of this piece measures 6" x 7" and compare that to the dimensions of your oval opening. If it will not work, you will probably need to call a local sheet metal shop or fabricator to customize a piece for your stove.

Will this fit Vermont castings Defiant model 1910?
By Collin C. - NFI Master Hearth Professional on April 2, 2012

Unfortunately, this boot will be a bit too small for your needs. Vermont castings uses a 5 3/8" by 9 3/4" oval opening on most of their stoves and manufacturers their own boot adapters.

We do carry a couple of boot adapters for single wall piping made by Heat-Fab. Please verify the size of the oval on your stove and I will be happy to assist you further.

By Terry Zinn from Lewisberry Pa. on August 25, 2012
The oval outlet on my stove is 8" X 4.25". Will this 6" X 7" boot connector fit this application?
By Tyler M. - Fireplace Specialist on August 27, 2012

Unfortunately no. This adaptor will not be wide enough on your oval's long side. In cases like yours, we recommend having a custom adaptor fabricated for you by a local machine shop or a sheet metal expert.

By Mark from Blairsville, GA on March 2, 2013
I'm looking for a oval to round connector with a oval diameter of 3 1/2 x 7 3/4. Do you make one in this size?
By Collin C. - NFI Master Hearth Professional on March 4, 2013

Currently, we do not offer an oval to round adapter with these dimensions. Many older stoves simply depended on ovalizing the end of a piece of round stovepipe. Upon checking the math, the circumference of your oval and a 6 inch stovepipe match. As such, your stove likely used a piece of ovalized 6 inch stovepipe to vent. If you do not want to proceed that route, a custom adapter would likely need to be fabricated by a sheet metal shop.

By Veralynne from Rockglen Saskatchewan, CAN on September 19, 2014
I have an old wood stove that I want to hook up. I would like to use 6 inch pipe and the stove has an oval outlet that is 8 and 3/4 inches long on the outside and 8 1/2 inches on the inside and 4 inches wide. Do you have something that would adapt that to a 6 inch stovepipe end. Would the 6 inch black steel stovepipe oval to round boot connector work for this? If not, do you have anything that would work?
By eFireplaceStore on September 19, 2014

Unfortunately, this adapter is a bit too large for your application. However, a custom oval to round adapter to fit your stove could be manufactured by a local sheet metal company.

By Brian from Richmond, VA on March 4, 2014
I have a warm morning model 521 wood stove with a top oval outlet length of oval measures about 8 7/8s in length and width 4 inches. Do you have a oval piece to 6 inch stove pipe to fit this? I will try and attach pics.
By Collin C. - NFI Master Hearth Professional on March 4, 2014

Based on the dimensions you have supplied for the outlet of the stove, the circumference of the opening is the same as a 6 inch circle. In these cases, there was usually not an oval adapter used. Instead, a 6 inch circular stovepipe would be ovalized at the male end, then pushed into the collar of the stove. Unfortunately, we do not carry an oval to round adapter that is a perfect fit. If you choose to use an adapter, you would have to work with a sheet metal fabricator to have one produced.

By Dale from TX on January 16, 2014
I bought an old wood cook stove that has a 9'' by 4'' hole on top. Does it need to connect to 6'' stove pipe? Is the snap-lock 6'' black steel stovepipe what I need?
By Collin C. - NFI Master Hearth Professional on January 16, 2014

This adapter could be further ovalized so that it would narrow the 6 3/16 inch end and slightly lengthen the 8 1/4 inch end. Even so, you may need to use a gasket to get a good seal.

It is worth noting that your 9 by 4 inch oval is the exact same circumference as a 6 inch circular pipe. Stoves that are an exact match where usually intended to work with a 6 inch pipe that has simply been ovalized on one end. As such, you could purchase the 6 inch pipe brand of your choosing, then ovalize the first piece to connect to your stove.

By Roy Bratt from Coopersburg, Pa 18036 on December 21, 2011
I have a portland foundry wood stove has embossed letter on the front of the wood stove that says ATLANTIC unit was included with my purchase of the home but does not have piping to connect the unit to the chimney. It has an oval outlet on the rear back facing side that measures 10 inches wide by 4 1/2 wide and is tapered wider at the base. This fixture also has 2 cuts to secure piping one top and one bottom. I have checked with all local suppliers nobody has piping to connect the unit. Chimney inlet would take standard 6" piping . From center of oval outlet to center of chimney piping is 20" high and the unit sets 16 inches off the wall. Would it be possible for you to tell me if you have anything that could adapt this unit? I cannot find any pictures of this unit on the web but here is a general description: has door on left side of unit, measures 10" wide by 15" long, has damper control on bottom half, and single handle open to front center of door. 2 doors front measures 10" wide by 15" high for a 20" by 30" opening total that you can insert a screen. Has a grey marble top plate 20" long by 11 1/2 wide and like I said has raised letters that say ATLANTIC above 2 front doors.
By Collin C. - NFI Master Hearth Professional on December 21, 2011

While we have all the 6" components to complete the installation, the oval boot will be an issue.

Many of these older stoves used an oval shaped outlet and almost every manufacturer has discontinued the production of them. Only a few products for Vermont Castings stoves exist. It is usually standard practice to have an oval adapter made out of 24 or 22 gauge sheetmetal, by a local fabricator.

We can then complete the rest of the stovepipe quote to finish the installation.

By Ken Reidy from Albuquerque, NM on June 21, 2012
I have an antique cast iron stove that has an oval outlet. The outside dimensions, circumference is 22 5/8". Will this boot fit? I am looking for a oval of this size to an 8" round.
By Collin C. - NFI Master Hearth Professional on June 22, 2012

Because of the fact that the oval may change in shape, I will need to know the width of the oval, as well as the height. This will guarantee that I have the proper information for your needs.

By Jo from Warwick, NY on December 2, 2013
I need a 3 inch by 6 inch stove pipe (oval) connector for a small pot belly stove (Montgomery Ward vintage 1950).
By Collin C. - NFI Master Hearth Professional on December 3, 2013

The outlet on your stove is roughly equivalent to a 4 inch round stovepipe. This is much smaller than any oval to round adapter outlet that we carry. As such, you will likely need to have an adapter fabricated by a metal shop.

By Christi from Dalton Gardens, ID on September 29, 2014
I need this adapter for my antique stove but I don't think I have snap lock pipe. Does it go OK with regular 6" stove pipe?
By eFireplaceStore on September 30, 2014

This adapter does not have to be used with Snap Lock pipe in particular. It is able to work with any 22 or 24 gauge single wall 6 inch black or stainless steel stovepipe.
By Nick from Windsor, CAN on October 1, 2014

I did not install my adapter yet but you will be just fine: the oval chute coming out from your stove doesn't have a snap-on as well this adapter.
The snap on is only for the round end which can work well with either snap-on or regular stovepipe.

By Andrew from USA on November 13, 2012
I have an old stove with a 73/8"x 4" oval opening for 8" single wall stovepipe. Do you have an oval connector that will fit this size?
By Collin C. - NFI Master Hearth Professional on November 14, 2012

Unfortunately, we do not carry an oval stove connector in this particular size. The oval opening you have is 2 inches narrower than the smallest adapter we stock. It is likely that you will need to have a local sheet metal shop fabricate an oval adapter for your installation, as the sizing is not standard. An adapter can be manufactured out of 24 or 22 gauge steel and can be welded or riveted at the seam, using stainless steel rivets.

By Craig Hall from Salinas Ca on January 27, 2014
I have old wood burning stove with the oval collar measuring 6.5 long ( could push it to 7") by 3" wide. Would this collar fit?
By Collin C. - NFI Master Hearth Professional on January 28, 2014

Unfortunately, the oval end of this adapter is too large for your application. The oval opening of your stove roughly corresponds to the area of a 5 inch circle. As such, you will likely need to have a custom adapter made by a metal shop, if you wish to vent to a 6 inch round chimney connector.

By Mike from Ontario, CAN on February 2, 2015
I have an antique Guelph wood stove that was built in Ontario, Canada that has an oval discharge. What is the standard size for oval discharges? I currently have a six inch pipe on my unit now.
By Tyler M. on February 2, 2015

This oval-to-round adaptor has an oval end measuring 8 1/4" x 6 3/16".

By bill elyasir from chicago, il on August 5, 2012
We have a pot belly stove. Its a kalmazoo longwood, The chimney pipe is 6 inches and we need an oval connection to the stove.The stove opening for the connection is oval and the connecting pipe is 6 inches and it goes into an oval opening. Is your part number cpf 73675 one that would work for this situation.
By Collin C. - NFI Master Hearth Professional on August 6, 2012

It is indeed possible that this adapter would work for your application. I am unable to find any detailed information regarding the dimensions of the opening on your stove. If you will, please provide the inside dimensions, long side and short side, of the oval.

By Dan Tanczos from Danielsville, PA on January 31, 2012
I have an old potbelly stove with a 7" x 4" oval opening for the pipe. Do you have an oval connector that will fit this size? What size round pipe do you recommend transitioning to?
By Kevin E. - Fireplace Specialist on February 1, 2012

Per your flue outlet dimension, we would recommend 6" diameter chimney system. We unfortunately do not have an oval-to-round adapter that will fit your 7"x4" opening. You have two options for connecting stove pipe to this appliance. You can either purchase single wall 6" stove pipe and compress the bottom end into an egg shape to fit your flue outlet. Or we can have a stove pipe adapter custom made for you. A custom adapter can be produced in 3-5 business days and ranges in price from $125 - $150. For a custom adaptor, you would supply a template depicting the exact dimensions required and we would have it produced exactly to your specifications.

By Phil from Michigan on November 26, 2013
My oval is 8 1/2" x 4 3/4". The circumference of the oval at the top is 22 1/4" which is very close to a 7" diameter. Would a 7" to 6" adapter work, and do you have one?
By Collin C. - NFI Master Hearth Professional on November 26, 2013

Unfortunately, we do not carry a 7 to 6 inch adapter that will have enough height to allow you to ovalize the 7 inch end without the 6 inch side partially ovalizing as well. If you are able to ovalize a section of 6 inch pipe to match, this may work. Otherwise, a custom adapter would need to be made.

By Ken from Idaho on November 4, 2011
I have an old wood stove I plan to install in my shop. It has oval opening for stovepipe.

I put string around it and measured it as if round and it was 6" round.

How do I measure to make sure the 6" black steel stovepipe oval to round boot stove connector will work for me?

By Collin C. on November 4, 2011

In order to make sure this adaptor would work for you, it will be necessary to measure the long and short sides of the oval. The long side needs to be 7" across and the short side 6" across for this adaptor to fit. On many older stoves, the stove adaptor was simply an ovalized piece of 6" round pipe. Since your oval is exactly 6" around, this is most likely the case, and you should be able to ovalize a standard 6" pipe to make the connection.

By ANDREW KUTZ from ORLANDO FLORIDA on January 16, 2012
What are the dimensions of the 6" oval pipe. My need is for a 2 1/2 x 6 1/2 oval pipe.
By Tyler M. - Fireplace Specialist on January 17, 2012

This piece has an oval end of 7" x 6". We recommend visiting a machine shop or a sheet metal fabricator to get a piece for your requirements.

By Cal from 57262 on March 22, 2012
How big is the oval? Mine is 9X4 in and the round is standard 6in single wall black pipe.
By Tyler M. - Fireplace Specialist on March 23, 2012

The oval end on this piece measures 7" x 6". For your application, we recommend having an oval-to-round adaptor fabricated by a local sheet metal or machine shop. Many older stoves had oval flue outlets, but, by and large, those are a thing of the past. As a result, there are only a few oval-to-round pieces still manufactured.

By Robin from United States on November 5, 2013
Our oval is 9" x 6" on the stove and I want to translate to 8 inch pipe. Which of your products will do the job? Also, is it OK to use double wall insulated pipe from the stove out through the roof, or do I need single wall for that part?
By Collin C. - NFI Master Hearth Professional on November 6, 2013

Unfortunately, your oval opening on your stove does not directly translate to the area of an 8 inch circle. This does not mean that 8 inch pipe should not be used, as the area is indeed close and the stove will operate fine. However, we do not have an adapter that will connect the stove to our 8 inch piping. As such, as custom adapter will need to be fabricated by a metal shop. This is often the case, as many older stoves used oval flue collars and they did not always follow a standard sizing pattern.

Once the adapter is made, it can be connected directly to single or double wall stovepipe. The double wall system allows for greater longevity and closer clearances to combustibles. This type of piping would be routed to the first combustible wall or ceiling. You would then convert to double or triple wall Class A chimney pipe for the remainder of the run.

By Loretta Smith from Roggen, CO on November 4, 2012
We have been restoring an antique Estate Oak Parlor stove that has an oval flue. We are looking for the oval-to-round boot, but how to you measure for this? Our oval measures 4-1/4" across and 9" in length.
By Tyler M. - Fireplace Specialist on November 5, 2012

Unfortunately, this oval-to-round adaptor will not fit on your flue collar. In cases such as yours, we recommend having an oval-to-round adaptor fabricated by a sheet metal expert or a local machine shop.
