M&G DuraVent 3×12 3PVL-12R 3″ x 12″ Pellet Vent Pipe
Best for straightforward pellet stove venting with a standard 3-inch diameter and 12-inch length. The unit is manufactured in the United States and emphasizes durability and ease of use. Ideal for homeowners seeking a reliable, no-fruss solution for a single straight run from stove to vent.
Who it’s best for: Homeowners needing a simple, durable, quick-install vent segment for a single straight run.
Caution: Availability of only a single 12″ length may require multiple sections for longer runs.
DuraVent PelletVent Horizontal Double-Wall Pipe Kit
This complete horizontal vent kit is designed for pellet and multi-fuel stoves, with a stainless steel inner wall and durable outer wall. It includes multiple 12-inch pipes, a 90-degree elbow tee, a cleanout tee with cap, and other components, making it a strong option for through-wall installations that require a robust, horizontal vent path.
Best for: Installers or DIYers needing a turnkey horizontal vent solution with all essential fittings included.
Caution: Horizontal installation requires careful alignment to avoid creosote buildup and ensure proper slope for drainage and cleaning.
M&G DuraVent 3PVL-E45R Elbow Insulated 3 Inch Double Wall 45 Deg
This insulated 3-inch double-wall elbow helps navigate corners or changes in direction. It is designed to maintain consistent venting temperatures and reduce condensation at bends, supporting safer and more efficient vent runs for pellet systems requiring angle transitions.
Best for: Installing around corners or tight spaces where a straight run isn’t possible.
Caution: Elbow fittings can introduce additional pressure drop; ensure compatibility with existing components and clearance requirements.
DuraVent PelletVent Stainless Steel Double Wall Straight Stove Pipe Connector
This double-wall straight pipe connector is designed to vent smoke and exhaust for multi-fuel options, with a robust interior and exterior construction. The PelletPro line emphasizes adjustable lengths and die-formed fittings to simplify installation without cutting or crimping.
Best for: Homes needing a versatile, durable connector that supports multi-fuel exhaust and adjustable lengths.
Caution: Data notes a focus on ease of alignment; verify that the length is sufficient for your run and that fittings nest securely with existing components.
Selkirk 3VP-6, 3″ x 6″ Pellet Stove Pipe
Selkirk’s 3VP-6 is a compact 3-inch by 6-inch pellet stove pipe designed as a Type L vent. It’s tested and listed to UL-641 and UL-103 standards, making it a safe choice for venting pellet appliances in smaller or vertically constrained installations.
Best for: Small footprint or vertical venting needs with UL-listed assurance for pellet venting.
Caution: The 6-inch length may limit certain configurations; plan for adequate vertical clearance and connection points during installation.
Buying Guide
What to consider when choosing a double-wall vent pipe
- Vent type and compatibility: Ensure the pipe matches your stove’s outlet size (commonly 3 inches) and that it is UL-listed for pellet use.
- Through-wall versus vertical installation: Horizontal kits simplify through-wall runs, while straight vertical pipes are straightforward for chimney-like venting.
- Material and durability: Stainless steel inner walls resist corrosion; outer walls should be durable and handle environmental exposure.
- Elbows and fittings: Angles (e.g., 45-degree elbows) help navigate corners but may increase friction and reduce draft if misused.
- Length and number of sections: Plan lengths carefully; multiple short sections may be easier to install than a single long run, but ensure proper slope for drainage and cleaning.
- Installation kit contents: Complete kits with tees, cleanouts, adapters, and wall thimbles save time and reduce fittings sourcing.
- Safety and clearance: Maintain clearances from combustibles and follow local codes for venting installations.
Practical installation tips
- Create a clear path for the vent from stove outlet to exterior termination.
- Use high-quality gaskets and seals to avoid leaks and odors.
- Inspect joints after installation and periodically during use for condensation or buildup.

Frequently asked questions
- What is double-wall vent pipe used for in pellet stoves?
– It provides an inner vent within an insulated outer wall to improve safety, draft, and efficiency by reducing heat transfer and condensation. - Is stainless steel better than galvanized for pellet venting?
– Stainless steel inner walls resist corrosion and provide longer life in venting applications; outer walls vary by product, but stainless inner walls are generally preferred for durability. - Can I install vent piping myself, or should I hire a pro?
– Simple straight runs may be doable for skilled DIYers, but professional installation ensures proper vent sizing, code compliance, and safe clearance. - How do I know the right length for my vent run?
– Measure the distance from the stove outlet to the exterior termination, account for elbows, and include extra for slope and cleaning access. - What maintenance is required for pellet vent piping?
– Regular inspections for soot, condensation, and corrosion are recommended; clean as needed following manufacturer guidelines.
