DuraVent 9017SSCF DuraPlus 6-inch x 36-inch Pipe Review
By Chimney Insight Editorial Team
Posted on October 23, 2026
1 of 1 — DuraVent 9017SSCF 6-inch by 36-inch DuraPlus stainless steel Class A chimney pipe section
Short verdict: The 9017SSCF is a 6-inch, 36-inch straight section for a DuraPlus Class A chimney system. Its triple-wall construction and twist-lock connection are well documented, but it is a system component—not a complete chimney, not connector stovepipe, and not a universal replacement.
Best for: extending a verified 6-inch DuraPlus installation where the plan specifically calls for a 36-inch stainless-outer straight section.

Pros and limitations
Pros
- Verified model 9017SSCF matches a 6-inch × 36-inch DuraPlus straight pipe section.
- Triple-wall construction combines insulation and a ventilated air space.
- Precision twist-lock joints simplify connection within the matching DuraPlus system.
- DuraPlus is documented for listed wood-, oil-, coal-, and gas-fueled appliances.
- The stainless-outer presentation suits exposed or exterior sections where that exact finish is specified.
Limitations
- Nominal 36-inch length does not equal installed contribution; DuraVent says to subtract 1.5 inches per joint.
- It cannot be mixed casually with unrelated pipe brands, series, diameters, or connector stovepipe.
- The section alone does not provide supports, firestops, flashing, storm collar, cap, adapters, or wall/ceiling protection.
- DuraPlus still requires at least 2 inches of clearance to combustibles.
- Correct installation depends on the appliance listing, route, local code, and the complete DuraVent instructions.
Verified specifications
Evidence note: System specifications and temperature statements come from current DuraVent documentation. Model, size, ASIN, weight, and package contents are confirmed by the exact retail listing. Chimney Insight has not performance-tested this pipe.
What this component is—and is not
DuraPlus is DuraVent’s triple-wall, all-fuel Class A chimney family. The 9017SSCF listing is the 6-inch-diameter, 36-inch-long straight section with the stainless appearance shown in the supplied product image. It extends a compatible DuraPlus chimney between the required support and termination components.
It is not ordinary single-wall or double-wall connector stovepipe. Connector pipe typically runs from an appliance to the point where the listed chimney system begins; Class A chimney continues through protected building penetrations and outdoors according to its listing. Substituting one for the other or joining incompatible series can defeat the tested system.
Construction and features
DuraVent documents a stainless-steel inner liner, aluminized-steel intermediate liner, and an outer wall that varies by finish. A ceramic insulation blanket and ventilated air space separate the walls. The ends use a precision twist-lock connection, so the section must mate with the same approved DuraPlus diameter and system components.
Documented temperature performance
DuraVent states that the DuraPlus system is designed for normal continuous operation at 1,000°F flue-gas temperature. The company also states that the system is subjected to high-temperature requirements including one hour at 1,400°F and three ten-minute chimney-fire tests at 2,100°F. Those are manufacturer-reported system test conditions—not permission to operate an appliance outside its listing or to continue using a chimney after a chimney-fire event.
If a chimney fire is suspected, stop using the system and arrange a qualified inspection. Extreme-temperature test language describes certification performance; it does not mean damage cannot occur in an actual fire or that post-fire inspection is optional.
Compatibility: the decision that matters most
The product is appropriate only when the complete design specifies 6-inch DuraPlus. Confirm the appliance outlet and listing, the required chimney diameter, the existing chimney’s manufacturer and series, and every transition component. A 6-inch nominal inner diameter does not make this pipe compatible with every 6-inch product.
DuraPlus is documented for listed wood stoves, fireplaces, furnaces, boilers, ranges, water heaters, and other appliances fueled by wood, oil, coal, or gas. That broad application describes the system family; the appliance manual and local code determine whether it is correct for a particular installation.
Planning the installed length
A common buying mistake is adding nominal section lengths and assuming that total is the finished chimney height. DuraVent instructs planners to subtract 1.5 inches per joint for 6- to 8-inch DuraPlus sections. A nominal 36-inch section therefore contributes less after it overlaps and locks into adjoining components. Calculate the complete stack rather than treating one section in isolation.
The manufacturer also notes that a straight vertical chimney at sea level may require roughly 10 to 15 feet above the appliance outlet for adequate draft, while elevation, elbows, and tees can require additional height. That is planning guidance, not a substitute for a system-specific draft calculation or code review.
Installation and safety checks
This review is not a substitute for the DuraPlus installation manual. Before ordering, map the entire route and verify the support method, ceiling or wall penetration, attic insulation protection, firestops, offsets, flashing, storm collar, roof bracing, termination cap, and appliance adapter. The straight pipe section cannot correct a missing or wrong system component.
- Verify identity. Confirm model 9017SSCF, 6-inch DuraPlus, 36-inch nominal length, and the specified outer finish.
- Protect clearance. Maintain the manufacturer-required 2-inch airspace to combustibles throughout the route; do not fill it with insulation.
- Calculate effective height. Account for joint overlap and every adapter, tee, elbow, support, and termination component.
- Follow roof rules. DuraVent’s documentation cites the common 3-2-10 termination rule and calls for an extended roof bracket when the chimney rises more than 4 feet above the roof penetration.
- Use qualified help. Penetrations, structural support, fire separation, and code compliance justify professional design and inspection.
Maintenance and inspection
Keep the chimney accessible for periodic inspection and cleaning in accordance with the appliance and chimney manuals. Watch for joint movement, corrosion, discoloration, impact damage, water entry, damaged flashing, missing clearance, and creosote accumulation. The cleaning method must be approved for the liner; aggressive tools can damage a listed system.
After severe overheating, a chimney fire, building work near the chimney, or a roof leak, do not rely on an exterior glance. Have the entire system inspected before further use.
Who should buy it?
Buy this section when a verified plan for a 6-inch DuraPlus chimney specifically needs a 36-inch straight length and the stainless-outer 9017SSCF variant. It is a sensible choice for replacing an identical approved component or completing a system whose model numbers and installed-length calculation have already been checked.
Who should avoid it?
Avoid it if you are identifying pipe only by diameter or appearance, if the existing system label is missing, or if you need connector stovepipe rather than Class A chimney. It is also the wrong purchase when the route needs a kit, support, tee, elbow, flashing, cap, adapter, or another DuraVent series instead of a straight DuraPlus section.
Frequently asked questions
Is the 9017SSCF a complete chimney kit?
No. The listing is for one 6-inch × 36-inch straight DuraPlus pipe section. A complete system requires application-specific supports, transitions, penetrations, weatherproofing, and termination parts.
Does a 36-inch section add exactly 36 inches of installed height?
No. DuraVent says to subtract 1.5 inches per DuraPlus pipe joint when calculating installed length.
Can it connect directly to any 6-inch stove pipe?
No. The transition must use the approved adapter and matching system components specified by DuraVent and the appliance manufacturer.
How much clearance does DuraPlus require?
DuraVent specifies at least 2 inches of clearance to combustible materials. Follow the current manual and local code throughout the entire route.
Can DuraPlus be used for wood, oil, coal, or gas appliances?
The DuraPlus system is documented for listed appliances using those fuels, but suitability still depends on the exact appliance listing and installation design.
Final verdict
The DuraVent 9017SSCF is a clearly documented, system-specific way to add a nominal 36-inch straight section to a 6-inch DuraPlus chimney. Consider it if every identity and layout check matches. Consider another component if you need connector pipe, a different series or diameter, a complete kit, or a part that solves an offset, support, penetration, or termination need.
Three checks before buying: read the existing system label; confirm the effective installed length; verify every required support, clearance, penetration, and termination component.
