Multi-fuel venting system. UL 641, ULC S609, and ULC/ORD C441.
A MAJOR CAUSE OF VENT RELATED FIRES IS FAILURE TO MAINTAIN REQUIRED CLEARANCES (AIR SPACES) TO COMBUSTIBLE MATERIALS. IT IS OF THE UTMOST IMPORTANCE THAT PELLETVENT BE INSTALLED ONLY IN ACCORDANCE WITH THESE INSTRUCTIONS. NOTE: Read through all of these instructions before beginning your installation. Failure to install as described in this instruction will void the manufacturer’s warranty, and may have an effect on your homeowner’s insurance and UL listing status.

CLEARANCES AND APPLICATIONS DuraVent’s PelletVent and PelletVent for multifuels is listed by Underwriters Laboratories as vent for listed oil-, pellet-, and corn-burning (multi-fuel) appliances. PelletVent is also listed as a masonry reliner, in which case the minimum clearance is 0” from vent to masonry, and 0” clearance from the masonry to nearby combustibles. Never fill any required clearance space with insulation or any other materials.
improvised solutions. 4. Practice good workmanship. Sloppy work could jeopardize your PelletVent installation. 5. Never use a vent with an inside diameter that is smaller than the appliance flue outlet. 6. Multistory: Where PelletVent passes through the ceiling, use DuraVent Firestop/Support assembly. 7. PelletVent placement: When deciding the location of your stove and vent, try to minimize the alteration and reframing of structural components of the building. 8.

Place the appliance according to manufacturer’s instructions. B. Cut a square opening in the wall in accordance with the dimensions in Table 1. The black portion of the Wall Thimble is to be attached to the interior wall, and the galvanized portion (stainless steel on CornVent) is to be attached to the exterior wall.

Use dimension “A” to determine total pipe requirements. Add 12 additional inches to 10 insure the termination is an adequate distance above the roofline. 5. The gross pipe required will be “A” dimension plus 12 inches. Five feet of this will be Flex Pipe. The remainder will be rigid pipe. For each joint, subtract 1-1/ 2 inches to allow for the overlap.

Once the horizontal pipe section is in place, the space between the pipe and the masonry may be filled with high temperature grout, as shown in Figure 17, if desired. 8. Install the Reduction Collar or Trim Collar, the 90° Elbow, and the vertical pipe section going to the appliance. An Adjustable Pipe length will probably be needed, as well as a Pipe Adapter. 9.

CLEANING AND MAINTENANCE 1. Have your system cleaned by a certified chimney sweep if you have doubts about your ability to clean it. Use a plastic or flexible steel brush. Do not use a stiff brush that will scratch the stainless steel liner of your system. 2. PelletVent systems must be installed so that access is provided for inspection and cleaning. 3. The pellet vent should be inspected at least once every month during the heating season. 4. Do not use chemical cleaners. They can damage the vent pipe. 5.
