Pellet Fuel Venting System

PelletVent Pro is a venting system designed for stoves and inserts that use wood pellets and oil fuels. It is also built to vent biofuel products such as corn, cherry pits, switch grass, soybeans, wheat, walnut shells, ect. (Rated for continuous use flue temperatures up to 570°F.)

Materials and Construction...

Laser-welded, double-wall pipe with a .012" inner wall of 444 Stainless steel and a .018" laser- welded galvalume outer wall. Painted black exterior available. Primary metal-to-metal connection seals joint. Encapsulated o-ring provides a secondary seal.

Clearances...

1" clearance to combustibles in the USA and Canada for appliances using corn and other biofuels, wood pellets or oil.

Planning Your Installation....

1. Refer to diagrams in catalog. (www.duravent.com or www.mheat.net) under catalogs.
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.
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 the 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. IMPORTANT! Check to be sure that the appliance and the venting system are in compliance with all minimum clearance to combustible requirements!

Design Recommendations...

The following design recommendations are a general guideline to assist in the design and selection of venting components for your installation. Always follow Duravent Installation instrutions before installing your chimney system (found with the cap or support box). 

• Size the vent to meet the appliance manufacturer's specifications.
• 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 an Appliance adapter to ensure a proper connection to appliance. Seal adapter to appliance with high temperature sealant.
• Use a Single Tee with Clean-Out Tee Cap to facilitate easy cleaning. It is recommeded to use a tee off the back of the appliance.
• In the United States and Canada, maintain the minimum 1" clearance (air space) from vent pipe to combustibles. Use proper support and bracing. Follow local building codes and have your venting system inspected. Be fire safe!
