Duravent PelletVent Stove Pipe PV Flex Trim Collar, 4"

A. The DuraVent 4PVP-FTC Flex Trim Collar connects 4-inch PelletVent Pro rigid pipe to stainless steel flexible relining inside a masonry chimney.

It provides a finished transition where the rigid vent system meets the flexible chimney liner. This helps create a clean, properly aligned connection for an approved pellet, biofuel, oil, or kerosene appliance venting installation.

The collar is intended for masonry-chimney relining applications. It is not a general-purpose wall trim collar or an appliance adapter.

A. The DuraVent 4PVP-FTC is intended for contractors, hearth professionals, and experienced installers connecting a 4-inch PelletVent Pro system to a flexible stainless steel masonry-chimney liner.

It is useful in homes, cabins, recreational properties, and commercial buildings where an existing masonry chimney is being relined for an approved appliance. The component helps the installer transition from rigid pipe to the flexible liner without improvising an unlisted connection.

Because venting affects fire safety and appliance performance, homeowners without chimney-lining experience should work with a qualified professional.

A. Yes, model 4PVP-FTC is the 4-inch Flex Trim Collar made for the DuraVent PelletVent Pro system.

The product is sized to connect compatible 4-inch PelletVent Pro rigid pipe to a stainless steel flexible reliner in a masonry chimney. DuraVent also offers a separate 3-inch version for systems that use 3-inch venting.

Check the appliance outlet, required vent diameter, rigid pipe, and flexible liner before ordering. Every component in the connection must be compatible with the approved vent system.

A. The swiveling female end makes it easier to align and connect the DuraVent 4PVP-FTC with the adjoining PelletVent Pro component.

Masonry-chimney installations do not always provide a perfectly straight or easily accessible connection point. The swiveling design gives the installer additional positioning flexibility while joining the rigid vent pipe to the flexible relining system.

The swivel supports alignment, but it does not correct an improperly sized or unsupported vent layout. The full installation must still follow DuraVent and appliance-manufacturer instructions.

A. No, the DuraVent 4PVP-FTC is designed to connect PelletVent Pro rigid pipe to stainless steel flexible relining installed in a masonry chimney.

The flexible stainless steel reliner forms the approved vent path through the chimney. The trim collar creates the transition between that liner and the rigid PelletVent Pro pipe at the fireplace or chimney opening.

Do not use this component as a substitute for a properly selected chimney liner. The liner size and installation must match the appliance and vent-manufacturer requirements.

A. The DuraVent 4PVP-FTC can be used within an approved PelletVent Pro system serving listed pellet, corn, other biofuel, oil, or kerosene appliances.

PelletVent Pro is a multi-fuel venting system available in 3-inch and 4-inch diameters. Its components are designed for appliances and inserts that use approved pellet fuels, selected biofuels, or liquid fuels identified by DuraVent and the appliance manufacturer.

Fuel compatibility is determined by the complete system and appliance listing, not by the trim collar alone. Always confirm the appliance manual before selecting the vent configuration.

A. The DuraVent 4PVP-FTC should be used with compatible DuraVent PelletVent Pro components rather than mixed with another manufacturer’s vent pipe.

A matching 4-inch diameter does not mean that another brand will have the same locking connection, dimensions, gasket design, or safety listing. Mixing components can create poor joints and may affect the vent system’s approval.

Use authorized components identified in the DuraVent instructions. Contact Rural Energy or a qualified installer when matching this collar to an existing vent system.

A. A typical installation also requires compatible 4-inch PelletVent Pro rigid pipe, stainless steel flexible relining, and the adapters, supports, and termination components specified for the chimney and appliance.

The complete parts list may include a flex liner section, appliance adapter, tee, clean-out components, rigid pipe lengths, elbows, chimney supports, flashing, or a termination cap. Requirements depend on whether the installation enters through a fireplace opening or the side of a masonry chimney.

The 4PVP-FTC listing is for the flex trim collar itself unless the product page specifically states that additional components are included.

A. The swiveling connection simplifies alignment, but installing the DuraVent 4PVP-FTC is only one step in a complete masonry-chimney relining project.

The installer must confirm liner sizing, chimney condition, vent routing, component support, joint engagement, clearances, and access for inspection and cleaning. Improvised parts or damaged components should not be used.

A trained hearth or chimney professional is recommended when the homeowner is not experienced with listed vent systems and stainless steel chimney relining.

A. The DuraVent 4PVP-FTC is both a finishing collar and a functional transition between PelletVent Pro rigid pipe and stainless steel flexible chimney relining.

A standard trim collar may only cover the opening around a pipe for a cleaner appearance. The 4PVP-FTC is specifically designed to complete the connection to a flexible reliner, and its female end swivels to make alignment easier.

Use the 4PVP-FTC when the installation requires the listed rigid-to-flex transition. Do not replace it with a decorative collar that does not provide the required connection.
