DuraVent Pipe Solutions

DuraVent manufactures venting systems for residential, commercial, and hearth applications, with product lines designed for different fuels, appliance types, installation methods, and code requirements. DuraVent products include all-fuel chimney systems, single-wall and double-wall stovepipe, pellet vent, direct vent pipe, Type B gas vent, stainless steel chimney liners, insulated masonry relining systems, concentric venting, polypropylene venting, and special gas vent products.

Because venting components are appliance-specific, it is important to choose the right product series, diameter, fuel rating, clearance, adapter, support, and termination. Chimney pipe, stovepipe, pellet vent, direct vent, Type B gas vent, and special gas vent are not interchangeable. Always confirm the appliance manual, DuraVent installation instructions, and local code before purchasing or installing any venting system.

WoodstovePro can help you identify the correct DuraVent product for your installation.

DuraVent DuraTech Chimney Pipe

DuraVent DuraTech is an all-fuel, double-wall chimney system used with approved wood stoves, fireplaces, furnaces, boilers, ranges, water heaters, and other listed appliances fueled by wood, oil, coal, or gas. DuraTech is also used with select factory-built zero-clearance fireplaces when approved by the appliance manufacturer.

DuraTech is one of DuraVent's most popular chimney systems for wood stove and fireplace installations. It is commonly used where an insulated chimney system is required through walls, ceilings, attics, rooflines, and exterior runs.

DuraTech products may include:

Pipe lengths
Elbows and offset components
Tee kits and tee caps
Ceiling support boxes
Wall thimbles
Roof supports
Attic insulation shields
Flashing and storm collars
Chimney caps
Adapters and finishing collars

If you are replacing an existing DuraTech part, make sure the diameter, series, and connection style match your current chimney system.

DuraVent DuraPlus Chimney Pipe

DuraVent DuraPlus is an all-fuel, triple-wall chimney system used with approved wood stoves, fireplaces, furnaces, boilers, stoves, ranges, water heaters, and other appliances fueled by wood, oil, coal, or gas.

DuraPlus is often selected for residential wood stove and fireplace installations where a listed chimney system is required. Its triple-wall construction uses insulating layers to help maintain proper flue performance while meeting the clearance and installation requirements specified by the manufacturer.

DuraPlus components may include chimney pipe lengths, elbows, tee kits, ceiling supports, wall thimbles, attic insulation shields, roof flashing, storm collars, chimney caps, and adapters.

If your system already uses DuraPlus, replacement parts should be matched to the DuraPlus product line. Do not assume other chimney pipe brands or DuraVent series will connect correctly.

DuraVent DuraChimney II

DuraVent DuraChimney II is a double-wall, air-cooled chimney system commonly used with masonry fireplaces and approved fireplace applications. It is designed as a factory-built chimney option for masonry fireplace projects that require larger chimney diameters and listed system components.

DuraChimney II is often used for fireplace installations, custom fireplace projects, and replacement chimney systems where the appliance or fireplace manufacturer specifies that type of chimney. Available components may include pipe sections, anchor plates, elbows, supports, firestops, chase top flashing, storm collars, and termination caps.

Because DuraChimney II is not the same as standard wood stove chimney pipe, the fireplace, chimney design, diameter, and installation requirements should be confirmed before ordering.

DuraVent DVL Double-Wall Stove Pipe

DuraVent DVL is a double-wall interior stovepipe used to connect an approved wood stove to a manufactured chimney system. DVL is commonly used when reduced clearances or improved connector pipe performance are needed compared with single-wall stovepipe.

DVL is a connector pipe, not a replacement for insulated chimney pipe. It is typically used in the same room as the appliance before transitioning to an approved chimney system at the ceiling support box, wall thimble, or other approved transition point.

DVL products may include straight pipe lengths, telescoping sections, elbows, adapters, trim collars, and damper sections. WoodstovePro can help you determine which DVL parts are needed for your stove-to-chimney connection.

DuraVent DuraBlack Single-Wall Stove Pipe

DuraVent DuraBlack is a single-wall interior stovepipe used to connect an approved wood stove to a manufactured chimney system. It is commonly used in the same room as the appliance when the installation has adequate clearances for single-wall connector pipe.

DuraBlack is a practical option for many wood stove installations, but it must not be used as chimney pipe through walls, ceilings, attics, closets, rooflines, or concealed spaces. Once the venting system reaches a wall, ceiling, or other transition point, it must connect to the proper approved chimney system.

DuraBlack products may include pipe lengths, adjustable lengths, elbows, snap-lock adapters, slip connectors, trim collars, and related stovepipe accessories.

DuraVent PelletVent Pro

DuraVent PelletVent Pro is a venting system for approved stoves and inserts that burn wood pellets, corn, oil, and certain biofuels when the appliance manufacturer allows that venting system. It is commonly used for pellet stove installations, pellet inserts, and other approved biofuel appliances.

PelletVent Pro components may include straight pipe lengths, elbows, tees, cleanout tees, appliance adapters, increasers, wall thimbles, supports, flashing, termination caps, and horizontal or vertical venting components.

Pellet vent systems must be sized and installed according to the appliance manual. The correct diameter, rise, run, termination location, outside air requirements, and clearances should be confirmed before ordering.

DuraVent DuraLiner Masonry Relining

DuraVent DuraLiner is an insulated, double-wall masonry relining system used with approved gas, pellet, oil, wood, or coal appliances. It is designed to help reline masonry chimneys while protecting the chimney from the effects of flue gas condensation and high-temperature appliance venting.

DuraLiner is commonly used for masonry chimney relining projects, fireplace inserts, heating appliances, and applications where an insulated relining system is required. Available products may include rigid liner sections, flex sections, adapters, tees, caps, top plates, insulation-related components, and installation accessories.

A chimney liner should be selected based on the appliance, fuel type, flue size, chimney condition, height, clearance requirements, and local code. WoodstovePro can help you determine whether DuraLiner is appropriate for your project.

DuraVent DuraFlex Stainless Steel Chimney Liners

DuraVent DuraFlex stainless steel liners are flexible chimney relining products for approved masonry chimney applications. DuraFlex products are commonly used with fireplace inserts, furnaces, boilers, water heaters, and other approved appliances fueled by gas, wood pellet, oil, or wood, depending on the liner type and appliance requirements.

DuraFlex may be a good option when a masonry chimney has offsets, tight spaces, or a flue path that requires a flexible liner instead of rigid liner sections. DuraFlex stainless steel liner options include different grades and constructions for different applications.

Before choosing a DuraFlex liner, confirm the fuel type, appliance manual, required liner diameter, chimney height, chimney condition, insulation requirements, and whether a stainless steel or aluminum liner is appropriate.

DuraVent DirectVent Pro

DuraVent DirectVent Pro is a coaxial, direct vent system for approved gas or propane stoves, heaters, and fireplaces. In a direct vent system, the venting system typically brings combustion air to the appliance while exhausting flue gases outside.

DirectVent Pro is commonly used with direct vent gas fireplaces, gas stoves, and gas inserts when the appliance manual lists or approves that venting system. Because direct vent products are highly appliance-specific, the appliance brand, model number, pipe size, termination style, and approved venting configuration must be confirmed before ordering.

DirectVent Pro components may include pipe lengths, elbows, wall thimbles, ceiling firestops, vertical terminations, horizontal terminations, flashing, storm collars, adapters, and decorative black interior components.

DuraVent CVS Concentric Venting System

DuraVent CVS is a concentric venting system used with approved condensing natural gas or propane appliances, certain Category II, III, and IV applications, and select approved direct vent or two-pipe configurations. CVS may also be used with certain approved pellet, oil, corn, and biofuel applications when the appliance manufacturer permits that system.

CVS is not a general-purpose substitute for chimney pipe, stovepipe, Type B gas vent, or DirectVent Pro. It should only be used when the appliance manual specifically approves CVS by name or confirms the correct listing and configuration.

WoodstovePro can help you determine whether CVS is appropriate for your appliance and which components are required.

DuraVent Type B Gas Vent

DuraVent Type B Gas Vent is used with approved natural gas or liquid propane Category I appliances, including certain gas fireplaces, gas-fired furnaces, boilers, water heaters, wall heaters, and space heating appliances.

Type B gas vent is designed for appliances that are tested and listed for Type B venting. It should not be used for wood stoves, pellet appliances, direct vent gas fireplaces, condensing appliances, or special gas vent applications unless the appliance manual specifically allows that product.

DuraVent Type B gas vent products may include round vent pipe, oval vent pipe, elbows, tees, caps, firestops, roof flashing, storm collars, supports, adapters, and related fittings.

If you are replacing existing B-vent, make sure the brand, model, diameter, and connection style match your current system.

DuraVent Special Gas Vent and High-Efficiency Venting

DuraVent also offers special gas vent and high-efficiency venting products for approved gas-fired appliances. Product lines such as FasNSeal, PolyPro, DuraSeal, and related systems are used for certain high-efficiency appliances, condensing boilers, furnaces, water heaters, tankless water heaters, and other approved venting applications.

These products are not interchangeable with Type B gas vent, DirectVent Pro, pellet vent, or all-fuel chimney pipe. Special gas vent and high-efficiency venting systems must be selected according to the appliance listing, operating temperature, pressure rating, fuel type, condensate requirements, and installation instructions.

Call WoodstovePro before ordering if you are not sure whether your appliance requires Type B gas vent, special gas vent, polypropylene venting, stainless steel venting, or another approved system.

DuraVent Chimney Caps, Supports, Flashing, and Accessories

Most DuraVent installations require more than pipe. A complete system may need supports, adapters, caps, flashing, storm collars, elbows, tees, wall thimbles, firestops, trim collars, attic insulation shields, roof braces, cleanout caps, and other accessories.

These components must match the correct DuraVent product series and diameter. Similar-looking parts may not connect correctly if they come from different product families.

WoodstovePro can help you identify:

The correct DuraVent pipe series
The proper diameter and part type
The right cap, support, flashing, elbow, tee, or adapter
Whether you need single-wall or double-wall stovepipe
Whether your project requires chimney pipe, pellet vent, gas vent, direct vent, or liner
