To my customers:
DuraVent has a MAP (Minimum Advertised Price), that, as a dealer in good standing, I must follow.  The prices I have published are to the penny, as low as I can PUBLISH.  DuraVent is a complicated product line, with many options.  Please call us at 888.321.5647 so we can help you with the parts you need for your installation.  At that time, we can take a look at your installation and provide you with LOWER PRICES to meet your needs.

Engineered Excellence
Thermal Tech blanket insulation, encased between dual walls of stainless steel, offers the optimum in safety and performance.

Thermal Tech Insulation
Thermal blanket insulation keeps the outer wall of the chimney cool, while ensuring high flue gas temperatures for optimum draft performance.  Encased between dual walls of stainless steel, Thermal blanket insulation is locked into position. This eliminates hot spots common with loose-fill type insulation. No sifting, setting, or dangerous voids.  In the event of a creosote fire, compressible blanket insulation permits the chimney liner to expand outward in a radial direction. The free floating liner design also permits the liner to expand in a longitudinal direction. This eliminates buckling and loss of structural integrity associated with solid-pack type installations.

Ease Of Installation
Sleek one-inch wall design provides for easy installations, such as installation through 16" on center rafters.  Lightweight insulation, combined with twist-lock fittings, provides for a new ease of installation.  Support boxes feature factory installed twist-lock fittings.  Elbows offer 360 swivel.

Stainless Steel Construction
0.016" 430 stainless steel outer wall.  .020" 430 stainless steel inner-liner (25% thicker than competitive chimneys for an extra margin of safety.)  Twist-lock end rings provide for ease of assembly.  Precision tooled end ring design seals the insulation chamber to prevent water and creosote from soaking into the insulation.

Listed by Underwriters Laboratories.  This 2100 Chimney has been tested and listed to the UL 103 HT standard, UL File #MH7399.  Designed for normal continuous operation at 1000 F flue gas temperatures, 6" and 8" diameters have been subjected to rigorous and stringent UL testing including one hour at 1400 F, plus three ten-minute chimney fire tests at 2100 F. 

Warranty
Limited Lifetime Warranty.

Q: How much pipe will the support box hold?
A: The square support and the flat support box will hold up to 60’ of pipe.  The round support box will hold up to 40’ of pipe.

Q: Do I have to frame around the support box?
A: Yes. All 4 sides need to be framed.

Q: Are you required to use a locking band for the joints of DuraTech pipe?
A: No. Locking bands are optional for DuraTech.

Q: Can I put screws in the joints of DuraTech pipe?
A: Yes. Screws are optional.

Q: Do I need to use a wall thimble when going through a concrete wall?
A: Yes. DuraTech requires a wall thimble whenever passing thru a wall.

Q: What is the longest piece of DuraTech pipe I can use through a wall thimble?
A: The maximum length of pipe thru a wall thimble is 2’.

Q: How far into the room does the DuraTech Pipe need to extend when going through a wall thimble?
A: 6” minimum into the room.

Q: Can I attach DuraTech directly to a free standing wood stove?
A: No.  Use stove pipe from the stove then transition to DuraTech.

Q: What seals the pipe as it passes through the wall thimble?
A: RTV, 500 degree F. or higher. Caulk the pipe to the thimble.

Q: How much pipe will a DuraTech tee support hold?
A: The DuraTech tee support will hold up to 60’ of pipe.

Q: Does the tee support go below or above the tee?
A: You can install the tee support above or below the DuraTech tee.

Q: Where would I find the information about framing the thimble or support box?
A: The Framing dimensions are in the DuraTech installation instructions. 

Q: What do I do when coming to an overhang or eave above?
A: There are 3 options to choose from;
        a) Penetrate the overhang.
        b) Box out the overhang.
        c) Offset the pipe with 30 or 15 degree elbows to go around overhang or eave.

Q: Can I add more than one elbow together to make an angle greater than 30?
A: No. You can only use sets of the same elbows. The maximum Offset is 30 degrees.

Q: How many offsets can I have?
A: DuraTech can have 2 offsets.

Q: What is the longest offset allowed with DuraTech pipe?
 A: Not more then 72” 2 sections max.

Q: How many elbow straps do I need for an offset?
A: If the total length of chimney sections between the (2) elbows is greater then 3 Feet, install a second elbow strap around the center of the chimney section.

Q: Can I offset directly on top of a support box?
A: No.  You must use a piece of pipe in the support box. Then you can start your offset.

Q: What adaptor should I use for a zero clearance fireplace?
A: The anchor plate.

Q: Can I offset directly on top of an anchor plate?
A: Yes.

Q: What is used to secure the transition anchor plate to the masonry chimney?

Chimney Design Recommendations

The following design recommendations are intended as only a general guideline to assist in the design and selection of chimney components for your installation. Read and follow the before installing your chimney system.

  • The size of the chimney should match the outlet size of the appliance. Improperly sized chimney results in poor draft and excessive creosote formation.
  • If possible, avoid the use of elbows, tees, and offsets that serve to restrict the natural draft. A straight vertical installation is more efficient and less likely to develop creosote.
  • Install the chimney in the interior of the structure whenever possible. A cold exterior chimney will produce less draft, and will generate more creosote.
  • Be fire safe! Maintain the minimum 2-inch clearance (air space) to combustibles. Use proper support and bracing. Follow local building codes and have your chimney inspected.


How To Plan Your Chimney Installation

Measure the diameter of the appliance flue outlet. Select chimney and black stove pipe with the same size flue dimension as the appliance.

Measure the roof pitch. For example, a 6/12 pitch has a vertical rise of 6" over a horizontal distance of 12". Select the appropriate flashing. See Drawing 1.

Determine the minimum chimney height above the roof line. Building codes require a minimum of three feet above the roof penetration, and at least two feet higher than any portion of a building within ten feet. See Drawing 1.

If an offset is required to avoid rafters or other obstructions, measure the horizontal distance required and the vertical height available. Refer to the offset tables. Use elbow straps to ensure adequate support. See Drawing 2.

Determine the total length of chimney and stove pipe required for the installation. To calculate the installed length, subtract 1 1/4" per joint of chimney pipe. Subtract 1 1/4" per joint for black stovepipe. Minimum chimney height, at sea level for a straight vertical chimney, is 10 to 15 feet above the appliance outlet. Higher elevations, or the use of elbows or a tee will require approximately 30 to 60 % more height to provide for an adequate draft.
