How do i get an airtight seal from my insert to chimney without installing pipe all the way up the existing brick chimney?
For an insert to work at optimal efficiency, you would need to run the liner all the way to the top. That is also the only way you can have a sealed collar plate with rain cap at the top of chimney.

I have a Majestic brand wood fireplace insert with an 8 inch prefab pipe chimney. Is it possible to line this with a 7 inch SS flexible liner and attach it to the existing fireplace with a bottom plate?
You can not and still maintain its UL listing. Pre-fab fireplace such as yours are tested along with the chimney to UL 127 and can not utilize a chimney liner (UL1777). Those liners are for general use or for stoves or inserts. In your case, the fireplace and the chimney system are considered all the same unit.

I am looking for double-wall chimney pipe for a 48" Majestic wood burning fireplace. This unit is about 25 years old. The old chimney measures 8" inner SS, 12.5" - 13" outer galvanized, longest pieces possible. I lost the top 12 ft or so of my chimney to a storm. Do you carry this product?
Unfortunately, this chimney system has been discontinued and we do not have any remaining stock.

I have an unlined masonry chimney for our open wood burning fireplace. What stainless steel liner would be recommended so that I do not have to rebuild the chimney to install clay tiles? Thank you.
Please note that proper relining will require removal of any broken flue tile. Once removed, the inner brick measurements would need to be provided in addition to the width and height of the fireplace opening and overall height of the chimney, measured from the hearth floor. You will also need to insulate the flexible chimney liner using a product like TherMix
or one of the other insulation kits

I am looking for a (4) 12" triple wall chimney pipes. The inside dimension of the pipe is 10" and the outside dimension is 15". I also need 4 storm collars and 4 caps.

I have an old brick home. It had a wall opening for a wood stove. My woodstove flue is 8". Can I use a stainless steel flex pipe kit? If not, what is a cheap alternative to vent my woodstove?
You could indeed use stainless steel flex vent for your stove, provided you have a masonry chimney that the liner will be running through. If this is the case, please provide the height from the top of the stove to the top of the chimney, and I will be happy to suggest a liner kit.

What type of pipe is required for a Yulkon Stove? I would like to use a 3" pipe. Your help would be appreciated.
I am unfamiliar with this brand of stove, but I was able to locate a "Yukon" brand of portable camping stoves. If this is the case, I do not see where these stoves can use 3" stovepipe. Additionally, we do not have access to stovepipe smaller than 5" in diameter.

I have a wood burning stove that had a brick chimney. The brick chimney was falling down so I had it demoed. I would like to back with an insulated stove pipe that I can build siding around. I can add pics if need be. However, I think I could just give the measurements to a professional and order the parts I need. Can you help me?
With the brick chimney no longer in place, the use of a prefabricated chimney system would be ideal. In order for us to create a comprehensive list of components, and to build a quote, please fill out our Chimney Pipe Design & Quote Form

Our builder suggests using double walled stainless steel pipes for the direct-vent propane fireplace in our new house. What do you recommend? It is a Green Smart 2, model 864TRV by Fireplacextrordinair.
That is correct, you will indeed need to utilize double wall direct vent pipe. From what I can tell in the manual for your unit, it appears the fireplace can utilize Dura-Vent Direct Vent Pro pipe. Below, please find a form that can be filled out for the request of a custom chimney quote:

I need a 4 inch diameter steel round stove pipe cleaning brush. Do you carry these?
If you have stovepipe that needs cleaning, using a steel brush will scratch the interior walls and damage the pipe. It is recommended to use plastic or poly brushes for manufactured chimney or stovepipe as this will not scratch the steel inner walls. In addition, it is a general rule of thumb to oversize the brush by 1", so the Schaefer Plastic Round Chimney Cleaning Brush
would be a good option as several sizes are available. If you do not see your size, it is recommended to cut the bristles down to the appropriate diameter. If you must have a wire brush, this is available here.

I have a Majestic insert fireplace model MBUC42 that currently has gas logs. Can I remove it and burn wood?
You can indeed. The MBUC42 is a wood burning model with provisions for a gas line. Before beginning to burn wood, I recommend having the chimney inspected by a chimney sweep to ensure it does not need to be cleaned prior to use as a wood burning model again.

I have a Montigo peninsula fireplace that has an exposed 8 inch vent pipe that I would like to cover in a more attractive smooth metal sheath of some sort. What would you suggest?
My best suggestion is to use a larger stovepipe that can be fitted over the existing pipe to conceal it. This would require partial disassembly of the vent pipe in order to slide the larger stovepipe into position.

I need some information about venting a wood burning stove through a wood frame house wall with vinyl siding with 6 inches of outlet from the stove. What do I need to know?
This type of installation will use a combination of single or double wall stovepipe and double or triple wall chimney pipe. Most commonly, black stovepipe will be run at least 12 inches off of the top of the stove before making a 90 degree turn to run horizontally toward the wall. The 12 inch height is the minimum, but additional height is always better. More height in the home will help the stove to establish proper draft and will cut down on the amount of chimney pipe you must use outside. Single wall stovepipe requires 18 inches of clearance to combustibles and is galvanized steel. Double wall stovepipe requires only 6 inches of clearance. While it is more expensive, the double walled pipe has a stainless steel inner wall and usually does not require replacement. As you near the wall, the stovepipe will use an adapter to convert to chimney pipe. A section of chimney pipe will then pass horizontally through the wall, using a thimble. Outside, you will need to install a chimney tee and tee support to direct the chimney pipe vertically along the side of the home. The chimney pipe must extend far enough above the roof to clear any obstructions or adjacent parts of the roof by 10 feet.

I currently have a gas fireplace and want to replace it with a wood burning stove. Do they use the same type of flue pipe?
They do not. Gas fireplaces will usually utilize a galvanized steel and aluminum vent pipe, while wood stoves will use a galvanized steel stovepipe in the room and then convert to double or triple wall stainless steel chimney. The caustic flue gases from a wood burning stove will degrade the aluminum piping used for a gas fireplace.

October 3, 2014
I recently purchased a Harmon Accentra pellet insert. I plan on running a 4 inch SS flexpipe down my existing brick chimney. Do i need to insulate the flex pipe?
Because pellet stoves rely on a combustion blower to initiate positive pressure in the liner, you will not need to use insulation. Unlike a wood insert, the flue gases do not have to be kept warm to maintain draft. The combustion blower will continue to push combustion byproducts, no matter how cold the air around the liner is.

I just purchased a pre-owned LOPI model FL wood burning insert. Do you sell a modification kit to connect a chimney liner kit to it? The opening in the pictures is 8 inches. I need a 6 inch liner for the chimney.
Because this is an older, pre-EPA insert, it was not designed with a direct connection to be made to the flue collar. The design required the insert to be installed into a masonry fireplace with a chimney liner that was already sized to the collar on the insert. The design of the damper and damper control rod makes it effectively impossible to install a collar or insert boot on the top of the appliance.

I have a wood burning stove that I want to put in my masonry fireplace. Do I need a stove pipe or can I just let it burn?
To guarantee that you do not have any drafting issues, I recommend running a short piece of stovepipe or flexible liner up through the damper area of the fireplace and into the smoke chamber. This will help to establish draft and prevent any problems with smoke pooling, especially of the unit is burned on a low setting.

What is the most economical way to vent a top vent wood stove insert up a masonry chimney?
By far the most cost effective solution is a 304 grade stainless steel flex liner. We offer several kits of varying length for this application. An example is the DuraFlex 6 Inch Diameter x 25 Foot Long Kit of 304-Alloy Light Chimney Liner
. This will include the adapter to connect the liner to the stove, as well as the support plate and cap.

I was given a Timberwolf 2100 as a Christmas gift. I am unsure of which chimney product is best for this stove. Can you give me a recommendation?
We recommend the DuraVent stovepipe and chimney pipe system. You can use DuraBlack pipe for a single-wall stovepipe installation in the room with the stove, then transition to double-wall insulated DuraTech class A chimney pipe. Or, if you prefer, you can use double-wall DVL black stovepipe before adapting to the DuraTech pipe. Please fill out our Chimney Pipe Design & Quote Form
for a full estimate with everything needed for installation.

November 16, 2013
When using an oval liner, should the adapter be sized so that the liner fits over the adapter or inside of the adapter?
When using sleeves and adapters, the male end of the liner should always be facing back towards the unit. This allows condensation to run back inside of the appliance as opposed to down the exterior of the liner itself.

How long does a gas liner last?
While longevity will depend on the amount or humidity in the flue gases, the typical liner can last for 20 to 25 years under normal conditions. In extreme circumstances where high humidity is present, the life expectancy can be cut in half.

We have a Comfort Glow B42LI-M wood burning box. First flue liner needs to be offset elbow. Should inner liner go inside outlet on box or should it be outside?
The general rule of thumb is for vent pipe to be installed male end down. So, the liner would go inside the flue outlet. Of course, most factory boxes require specific brands of pipe that feature locking tabs and ensure a proper fit/connection.

We are looking for a chimney pipe for a fireplace in a modular pre-built home: 12” x 8” x 4’ silver .
We live at 5600 feet elevation and our present chimney is 10’ high from fireplace to top, 4’ above roof. We have a problem with smoke in the house.
We want to extend our chimney for better draft.
From these measurements, it appears you may have triple-wall solid-pack chimney pipe. Can you provide the manufacturer of your existing pipe, so we can check availability of a compatible 4-foot piece? We would also recommend adding an extended roof support piece, since your pipe will extend eight feet over your roof; an extended roof support is intended for use when the pipe protrudes further than five feet above the roof.
Please reply with the manufacturer of your current pipe and we will be happy to assist you in finding the appropriate pieces.
I have a modular home too, 2002 model. They use FMI pipe. 8 inch stainless inner pipe and a 12 inch outer pipe. Hope this helps.
