Pellet-fuel venting system.
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 is listed by Underwriters Laboratories as a vent for listed oil-, pellet-, (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 (except insulation explicitly approved by DuraVent as noted below).
not eliminate the need for inspection and cleaning. During the heating season, inspect monthly, and clean at least once a year. PERMITS Contact your local building department or fire officials regarding any needed permits, restrictions, and installation inspection requirements in your area. GENERAL INSTALLATION INSTRUCTIONS PelletVent is listed with a minimum 1” clearance to combustibles. Refer to Table 1 for framing requirements needed for these components. 1.

Cap can be swiveled to be directed away from nearby objects (fence, plants, etc.), but must still be pointing in a generally downward direction. Important: Horizontal Caps must be pointed in a generally downward direction to insure rain and snow do not enter the cap, and cause potential damage to the appliance. Either vent Cap should be at least 6” from the wall. C. Follow the appropriate code for proper distance of exit terminal from windows and openingsNFPA 211 (2010 ed.) Section 10.4 Termination: 10.4.

determine it’s structural condition. 2. Carefully read the pellet stove or insert installation instructions. 3. Measure and record the dimensions as shown in Figure 8. 4. Use dimension “A” to determine total pipe requirements. Add 12 additional inches to insure the termination is an adequate distance above the roofline. 5. The gross pipe required will be “A” dimension plus 12". Five feet of this will be Flex Pipe. The remainder will be rigid pipe. For each joint, subtract 1-1/ 2" to allow for the overlap.
C B TOP VIEW 12 INCHES TO END OF PIPE A through the flashing to the desired height. Mark where the Storm Collar will go. Slip the Storm Collar down over the pipe, and affix it to the pipe with a 1/4”long stainless steel sheet metal screw. (Figures 13 & 14). The Storm Collar will then support the entire vent system. Install the Cap. Seal the joint at the Storm Collar, and any other joints or seams which may appear suspect.

Drill a small hole through the ceiling at this point, so it can be located from the top of the roof. 4. From the roof, locate and mark the outline of the Support Box. 5. Remove shingles or other roof covering as necessary to cut the rectangular hole for the Support Box. Cut the hole 1/8" larger than the dimensions of the Support Box. (Figure 19).

point, moisture in the exhaust condenses in the vent, which can lead to accelerated vent corrosion. Maintain hot flue gas temperatures. It is recommended that the vent run inside the building envelope or inside a chase enclosure to minimize the vent’s exposure to cold temperatures. Be sure to follow all-applicable building codes and the requirements of the vent and appliance manufacturers. Appliance Operation: Always operate your appliance in accordance with the appliance manufacturer’s recommendations.
