Examples and Diagrams of typical DuraVent PelletVent Pro Installations

1. Refer to the Typical DuraVent PelletVent Pro Installations diagram, on this page, to be familiar with some of the standard PelletVent Pro installations and the required component parts.
2. For a horizontal termination, you will need a Wall Thimble and a Horizontal Cap. The cap
must be installed with a 6" clearance to the outside wall (refer to appliance manufacturer’s
installation instructions for other clearances).
3. For a vertical termination, you will need a Cathedral Ceiling Support Box or Flat Ceiling
Support, Attic Insulation Shield (if passing through an attic), Flashing, Storm Collar, and
Vertical Cap.
4. Determine the length of PelletVent Pro pipe required. For a vertical termination, measure the pitch of the roof and select the proper flashing. The required minimum height above the roof is 12".
5. Pellet stove inserts in masonry fireplaces will require a flex pipe to snake the vent past the
smoke shelf. For transition from PelletVent Pro to an existing DuraPlus, DuraPlus HTC, or
DuraTech Chimney, a Chimney Adapter is available.
6. For vertical rise of PelletVent Pro on the outside of the house, Wall Straps should be used at 4' intervals to provide proper support.
7. Check to be sure that the appliance and the venting system are in compliance with all minimum clearance to combustible requirements.
Important: Always use common sense and good construction/installation practices and comply with all local fire codes. Take the time to read the pellet stove/insert manual and the Installation Instructions for Dura-Vent PelletVent Pro. If you feel unsure about any installation issues we recommend you consult with a licensed contractor, building official or fire marshall.

Also, check for any venting restrictions such as maximum horizontal run, minimum and maximum vertical rise, maximum offset, etc.
  • Avoid long runs and excessive use of elbows. Refer to the
    appliance manufacturer for minimum rise and maximum run
    configurations for the venting system.

Please note: For safety considerations and ease of installation follow these guidelines:

1. Download and read the Installation Instructions for Dura-Vent PelletVent Pro. This manual will answer most questions regarding installation. Also consult your pellet stove manual for specific information regarding outside air or other issues specific to your pellet stove or insert.
2. It is your responsibility to comply with all local fire codes regarding installation of the stove, pipe and any options or accessories. Read the stove or insert manual carefully regarding assembly and installation. Always use common sense and good construction/installation practices. If you feel unsure about any installation issues we recommend you consult with a licensed contractor, building official or fire marshall.
3. Never mix and match different brands of pellet stove pipe. The connection will most likely differ from Brand X to Brand Y and may cause leaks.
4. Never use "regular" single wall or double wall stove pipe for pellet stoves or inserts. Burning pellets causes a more corrosive environment and "regular" stove pipe will not last.
5. In the United States the minimum clearance to combustibles from PelletVent Pro is 1” for oil, pellet, corn or other biofuel applications.
6. Sections of pipe are connected to each other by pushing them firmly together and twisting. Screws are not required. However, if screws are desired, use 1/4”-long sheet metal screws. Important! Do not penetrate the inner liner with screws.
