The best pellet stove vent pipe kit depends on the stove’s required vent diameter and whether the installation exits through a wall or roof. The DuraVent and Selkirk options are 3-inch venting products; the Comfortbilt kit is another 3-inch piping option. The two remaining products are 2-inch outside-air intake kits, not exhaust vent kits. Compare them only if you also need to bring combustion air into the stove.

DuraVent PelletVent 3-Inch System

The DuraVent PelletVent 3PVL-KHA is identified as a 3-inch pellet stove venting system. It is a relevant option for shoppers looking for a pellet vent product rather than an outside-air intake hose. The listed product information does not specify the included components or installation direction, so confirm the package contents and layout requirements before ordering.
Best for: Buyers whose stove documentation calls for a 3-inch pellet venting system and who are comparing dedicated vent products. It was selected because its name identifies both pellet-stove venting and a 3-inch size.
Limitation: The supplied product details do not establish whether it is a complete kit for a particular wall or roof route. Verify the parts list and stove requirements rather than assuming it contains every fitting.
Selkirk 3-Inch Type L Pellet Kit

The Selkirk Corp 283870 is a 3-inch Type L pellet kit described for pellet stove applications. Its defining installation constraint is that it is designed for horizontal installations only. That makes it a clearer match than a general venting product when the planned route passes through a wall horizontally, provided the stove instructions and the kit instructions also permit the proposed arrangement.
Best for: Buyers planning a horizontal through-the-wall installation who need a 3-inch pellet vent kit. It was selected because its supplied description directly identifies the application, size, and orientation.
Limitation: Do not choose it for a vertical-only route based on the supplied product description. Check the kit’s included parts and installation directions before purchase.
Comfortbilt Black Matte 3-Inch Piping Kit

This Comfortbilt kit is described as double-walled PVP piping with a black matte finish. The product information also calls out two important details: the 90-degree elbow for a downturn is not included, and the 45-degree swivel cap is available only in galvanized color. Those details can affect both the planned route and the appearance of the finished installation.
Best for: Buyers considering a 3-inch piping kit who want a black matte finish and have checked that the listed configuration fits their layout. It was selected because it is specifically described as pellet stove piping and identifies its construction and finish.
Limitation: The missing 90-degree elbow means buyers who need that turn must account for it separately. Do not assume every pictured or desired fitting is included.
2-Inch Pellet Stove Fresh Air Intake Kit

This product is an outside-air intake kit, not an exhaust vent pipe kit. Its listed hose has a 2-inch inner diameter and can stretch up to 60 inches. The description specifies an aluminum flex hose and 304 stainless steel mounting panels, with rust-, corrosion-, and heat-resistance characteristics stated for the panels. It is intended to bring outside air to a pellet stove when the existing room-air supply is insufficient.
Best for: Buyers who need a separate 2-inch outside-air connection and have confirmed the stove’s intake size. It was included because intake is a related part of planning a complete stove installation, though it does not replace exhaust venting.
Limitation: Confirm both the 2-inch size and the required hose length before purchase. Its intake purpose makes it unsuitable as a substitute for a flue or exhaust vent.
2-Inch Pellet Stove Outside Air Kit

This second 2-inch product also supplies outside air rather than carrying exhaust. Its description lists an aluminum hose with a 2-inch inner diameter and a flexible stretch length of up to 60 inches. It also identifies a 304 stainless steel component and describes the materials as resistant to rust, heat, and weather. Check the package details to understand exactly which pieces are included.
Best for: Buyers looking for a flexible outside-air connection and whose stove calls for a 2-inch intake. It was selected as a related accessory option, not as one of the three exhaust-piping choices.
Limitation: It is not a pellet vent. Avoid choosing it to route combustion exhaust, and confirm the size and installation needs for the specific stove before ordering.
Buying Guide: How To Choose Pellet Stove Vent Pipe Kits
Do you need exhaust venting or an outside-air intake?
Start by identifying the function of the part you need. Exhaust venting carries combustion products away from the stove. An outside-air intake supplies air to the appliance. They serve different purposes and are not interchangeable. In this list, the DuraVent, Selkirk, and Comfortbilt products are described as pellet venting or piping options. The two 2-inch products are intake kits.
If you are replacing or adding exhaust pipe, compare products described for pellet-stove venting. If your installation also requires an outside-air connection, assess that intake separately. A product called an air kit should not be treated as a flue simply because it includes flexible pipe.
Which pipe diameter does your stove require?
Use the size specified in the stove manual and the vent system instructions. The products listed here include 3-inch venting options and 2-inch intake options; those numbers describe different product types and should not be compared as if they were alternate sizes of the same component. Do not infer that a 3-inch vent kit or a 2-inch intake kit will fit a particular stove without checking its requirements.
For a replacement, compare the existing installation’s size with the stove documentation and the new product’s exact specifications. If the required size or connection is unclear, seek guidance from the stove manufacturer or a qualified installer before buying.
Is the planned route horizontal or vertical?
Map the route from the stove to the termination point before selecting a kit. The Selkirk description specifically limits the kit to horizontal installations. The supplied information for the DuraVent and Comfortbilt products does not confirm that either is suitable for every route, so check their instructions for the intended orientation and required fittings.
A route that turns, rises, or exits through a wall may require particular parts. Review the product’s parts list rather than assuming a kit includes every elbow, cap, adapter, or support needed. The Comfortbilt listing, for example, explicitly says the 90-degree downturn elbow is not included.
What should you verify in the package contents?
Look for a clear component list and compare it with the planned installation. Check whether the kit includes the pipe sections and termination pieces you need, and identify any separately required components. Product names alone do not confirm that a kit is complete for a specific home or stove configuration.
- Confirm the vent or intake function and the correct diameter.
- Check the permitted installation orientation and the route requirements.
- Review which elbows, caps, adapters, and mounting pieces are included.
- For intake hoses, check the maximum stretch length and the stove connection size.
- Confirm the product instructions and stove manual agree on the proposed setup.
Should you prioritize finish or installation fit?
Appearance can matter, particularly where piping is visible, but fit and the required components come first. The Comfortbilt product is described as black matte, while its 45-degree swivel cap is noted as galvanized. Consider that difference if a consistent visible finish matters. Do not trade a required connection or compatible configuration for appearance.
When should you ask an installer?
Ask a qualified installer when the route, component compatibility, or local installation requirements are uncertain. Follow the stove and vent manufacturers’ instructions and check applicable local requirements before work begins. This is especially important when combining parts from different systems or changing an existing vent layout. The product details provided here are not enough to establish that any kit suits every installation.
Frequently Asked Questions
Are pellet stove vent pipe kits the same as fresh-air intake kits?
No. Vent pipe carries exhaust away from the stove, while a fresh-air intake kit supplies outside air. The two types serve different functions and should not be substituted for one another.
Which listed product is specified for horizontal installation?
The Selkirk Corp 283870 Type L Pellet Kit is described as a 3-inch through-the-wall kit designed for horizontal installations only. Check its instructions and the stove documentation for the proposed setup.
Does the Comfortbilt kit include a 90-degree elbow?
No. Its supplied product details state that the 90-degree elbow for a downturn is not included. Buyers who need that turn should verify the required part separately.
Are the two 2-inch kits exhaust vent kits?
No. Both are described as outside-air intake kits. Their listed 2-inch dimensions refer to the intake hose, not to an exhaust vent specification.
How do I know whether a 3-inch vent kit will fit my stove?
Check the stove manual and the vent kit instructions for the required diameter and connection. The product name alone does not confirm compatibility with a specific stove.
Does a kit necessarily include every fitting for an installation?
No. Included parts vary by product, and the supplied details do not confirm that every listed kit contains all components for every route. Review the package contents and identify any separately required fittings before ordering.
