Multi-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 and PelletVent for Multi-Fuel is listed by Underwriters Laboratories as 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.
provided it is inside the fireplace, and the fireplace has completely sealed surroundings. 11. Do not connect B-Vent pipe with aluminum liners to pellet appliances. 12. Inspections: Using pelletized fuel does not eliminate the need for inspection and cleaning. During the heating season, inspect monthly, and clean at least once a year.

Connect the Pipe Adapter to back of stove and attach sufficient pipe to penetrate Wall Thimble and extend at least 6” beyond the exterior wall. You may install the optional House Shield as shown in Figure 6. The House Shield is used to protect the exterior wall from vent discharge. Attach a Square or Round Horizontal Cap.

Once all the components are firmly seated and properly aligned, carefully drill three 1/8” diameter holes through the outer sleeve only in the center of the slots located at the bottom of the Adjustable Length pipe. Do not penetrate the inner liner. Use (3) 3/8” length sheet metal screws to secure the Adjustable Length pipe. The completed installation will look like Figure 7.

INSTALLATION IN A CATHEDRAL CEILING 1. Mark a line on the side of the Cathedral Ceiling Support Box to correspond to the line of the roof pitch, as shown in Figure 18. Allow for the Support Box to protrude below the low side of the finished ceiling a minimum of 2". 2. Position the appliance at its proper location on the floor. Pay close attention to the manufacturer’s installation instructions regarding the distances from combustibles, etc.
