    Pellet Vent Pipe

    For stoves that use pellet fuel or corn pellets, pellet vent pipe is exactly what you need. Pellet vent pipe is specifically designed to remove the exhaust gases and fine ash that pellet fuel creates when burnt, even though it is often not visible. Choose the pipe to fit your corn or pellet stove from our extensive selection to make sure that your stove works cleanly and efficiently for years to come.

    What is the procedure for installing pellet vent piping?
    By Tyler M. - Fireplace Specialist on January 3, 2013

    Answer:
    Because pellet stoves operate using a combustion fan system, their venting systems share many similarities to direct vent gas appliances. Like direct vent fireplaces, pellet venting can be routed horizontally to an outside wall and terminated or it can be routed vertically for a short run before terminating. It is recommended to employ a short vertical run externally before terminating, as this will prevent the appliance from leaking smoke into the room if a power outage is experienced. Having the short vertical run allows negative pressure to pull residual smoke from the appliance after shutdown. For cleaning purposes, it is recommended to keep the vent run free of any unneccessary bends or turns. This will allow you to complete the cleaning procedure more effectively and prevent the build up of ash in the vent system. Of course, each pellet stove manufacturer will differ and it is important to employ an installation that will meet their standards. Local codes should also be consulted. With this information in hand, our NFI trained technicians will be happy to put a materials quote together for you, via our vent quote form.

    I am looking to Install a Breckwell P23FSL Pellet stove. Can it be directly vented into my existing masonry chimney or do I have to put in a chimney liner? Will it vent correctly if it is direct vented?
    By eFireplaceStore on December 19, 2014

    Answer:
    This unit is able to be vented into a masonry chimney, but a liner must be installed in order for the unit to vent directly. The relatively large cross section of a masonry chimney flue will cause flue gases to stagnate otherwise, which can lead to spillage of combustion gases back into the room and generally poor operation.

    What type of chimney flex liner can I use for the exhaust on a pellet stove? It will be going in an existing masonry chimney.

    I have a Whitfield Advantage II WP2 Insert pellet stove and 25' Masonry chimney.
    By Collin C. - NFI Master Hearth Professional on October 29, 2013

    Answer:
    According to the manual for your stove, the cutoff to switch from 3 inch to 4 inch occurs at approximately 23 feet. As such, a 4 inch stainless steel flex liner should be used.

    I have a new pellet stove and I want to run the piping through the existing wood-burning fireplace chimney flue. Is there a special plate/adapter that I put in the flue to allow the pipe to pass through but keep the rest of the air space closed?

    By Will M. on December 22, 2015

    Answer:
    This is typically done by cutting sheet metal to fill the void between the damper opening and pellet vent.

    How far from a window must the pellet vent pipe be from windows?
    on November 9, 2012

    Answer:
    Per national code, the termination for a conventional pellet vent appliance cannot be closer than 4 feet to a door or window. Please be sure to check with your local code office, as they may have a different requirement. Local jurisdiction has final authority. Please let me know if I can assist you further.

    i am purchasing a pellet stove and from what I have read, living at 7500 feet, I need a 4" horizontal kit. I like the Selkirk product but do not see 4" pipe kit.
    Do you carry something like this?
    By eFireplaceStore on November 23, 2015

    Answer:
    For horizontal venting, Selkirk makes a direct vent style of product. An example is the Selkirk Direct-Temp Straight-Out Horizontal Direct Vent Termination Kit. The kit can be used with the applicable length of pipe to vent through the wall.

    I have a Paragon by US Stoves model 5440,5440Q. All my vent pipe is the 3 inch DuraVent twist lock pipe. I am looking for an adapter to go from the stove to the 3" pipe. The pipe coming out of the stove is 3 inch and the 3 in pipe will not fit over it to connect to the stove. Do you carry an appliance adapter for this stove?
    By Collin C. - NFI Master Hearth Professional on December 4, 2013

    Answer:
    The part you are referring to is the appliance adapter. The item is available in unpainted galvalume, which is the Dura-Vent PelletVent Pro Galvalume Appliance Adaptor - 3-Inch Inner Diameter - 3PVP-AD or it can be had in a painted black version, which is the Dura-Vent PelletVent Pro Black Appliance Adaptor - 3-Inch Inner Diameter - 3PVP-ADB. The adaptors use a tapered inner wall that pushes into the flue collar of the appliance, allowing the venting system to twist and attach to the other end.

    Can a Harmon XXV pellet stove be vented directly into a 12 x 8 lined masonry chimney? Is there sufficient draft?
    By Collin C. - NFI Master Hearth Professional on November 26, 2012

    Answer:
    Per the published information for this stove, it is indeed possible to vent this model into a clay lined masonry chimney, as long as the clay tiles are proven to be in good condition. The combustion fan will provide adequate positive pressure for the unit to draft in this way.

    Lining the chimney with a 4 inch stainless steel liner is recommended if the condition of the chimney is questionable in any way.
