Pellet Stove Venting

Read manufacturer PDF instructions for installing venting system for pellet, corn oil and biofuel application. Inside you'll learn about clearances, sealants, fuel selection, best practices, installation into masonry fireplaces, installation though the side of masonry chimney, installation in a cathedral ceiling and general cleaning and maintenance.
Read this manual for combustion air system installation. The combustion air system brings in outside air for pellet stoves.
Always use common sense and good construction/installation practices and comply with all local fire codes. If you feel unsure about any installation issues we recommend you consult with a licensed contractor, building official or fire marshall.

  1. Planning the Installation
    • 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).
    • For a vertical termination, you will need a Cathedral Ceiling Support Box or Flat Ceiling Support Box, Attic Insulation Shield (if passing through an attic), Flashing, Storm Collar, and Vertical Cap.
    • 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".
    • 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.
    • For vertical rise of PelletVent Pro on the outside of the house, Wall Straps should be used at 4' intervals to provide proper support.
    • Check to be sure that the appliance and the venting system are in compliance with all minimum clearance to combustible requirements.

Tips

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.
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.
