1. Refer to the Typical 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.

Helpful Information

The inner pipe diameter should match the outlet size of the appliance. For installations that require 4” vent and the appliance has a 3” outlet, use an Increaser Adapter 3”-4”. Check the appliance manufacturer's installation instructions to confirm which types of vent configurations are permitted (i.e. horizontal, vertical, chimney reline, etc.). 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. Use a Single Tee with Clean-Out Tee Cap to facilitate easy cleaning. It is recommended to use a tee off the back of an appliance. Maintain the minimum 1" clearance (air space) from vent pipe to combustibles. Use proper support and bracing.
