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). Combustible
materials include (but are not limited to)
lumber, plywood,sheetrock, plaster and lath,
furniture, curtains, electrical wiring, and
building insulation except that noted below.
The minimum clearance to combustibles
from PelletVent is 1” for oil, pellet or other
approved fuels. 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 double wall pellet vent be installed
only in accordance with these Instructions.
