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. Combustible
materials include (but are not limited to)
lumber, plywood,sheetrock, plaster and
lath, furniture, curtains, electrical wiring,
and building insulation of any kind. In the
United States the minimum clearance to
combustibles from PelletVent is 3" for oil,
pellet or other biofuel applications. 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.
For other components not listed
(components not in contact with exhaust
gases), use a regular PelletVent component
(examples: Support Boxes, Tee Support
Bracket, Flashing).

INSTALLATION NOTES
For the purpose of these instructions,
PelletVent will collectively include PelletVent
and PelletVent for Multi-Fuel, unless
PelletVent for Multi-Fuel is specifically called
out. Proper planning for your PelletVent
installation will result in greater safety,
efficiency, and convenience,saving both time
and money. Use only authorized DuraVent
PelletVent listed parts. Do not install
damaged parts. When installing multi-fuel
appliance or an appliance that can burn
pellets, use PelletVent for multi-fuel parts as
specified above.
1. WARNINg: When passing through
ceilings and walls, make sure all combustible
materials and building insulation products
are a minimum of 3" from the vent pipe.
2. When exiting through walls, make sure
NFPA rules are followed for distance from
windows and openings.
3. Do not mix and match with other products
or 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. Sections of pipe are connected to each
other by pushing them firmly together and
twisting. Screws are not required. If however,
screws are desired, use 1/4"-long sheet metal
screws. Under no circumstances penetrate
the inner liner with screws.
9. RTV Sealant may be required at all vent
joints. Refer to Appliance manufacturer.
10. Never install single-wall pipe to
freestanding pellet stoves. Single-wall pipe
may be connected to a fireplace insert,
