INSTALLATION NOTES
Proper planning for your PelletVent Pro
installation will result in greater safety,
efficiency, and convenience, saving both time
and money. Use only authorized Dura-Vent
PelletVent, CornVent, and PelletVent Pro
biofuel listed parts. Do not install damaged
parts.
1. WARNING: When passing through ceilings
and walls, make sure all combustible materials
and building insulation products are a
minimum of 1” from the vent pipe
2. For horizontal terminations, make sure
NFPA 211 rules are followed for minimum
distance from windows and openings.
3. Do not mix and match with other
manufacturer’s products or improvised
solutions.
4. Practice good workmanship. Sloppy
work could jeopardize your PelletVent Pro
installation.
5. Never use a vent with an inside diameter
that is smaller than the appliance flue outlet.
6. Multistory: Where PelletVent Pro passes
through the ceiling, use Dura-Vent Firestop/
Support assembly.
7. PelletVent Pro 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. However, if
screws are desired, use 1/4”-long sheet metal
screws. Important! Do not penetrate the inner
liner with screws.
9. Never install single-wall pipe to freestanding
pellet stoves. Single-wall pipe may be
connected to a fireplace insert, provided it
is inside the fireplace, and the fireplace has
completely sealed surroundings.
10. Do not connect Type B Gas Vent pipe with
aluminum liners to pellet appliances.
LUBRICANTS & GASKETS
PelletVent Pro utilizes an internal O-ring
gasket on the outside of the inner liner in the
female end of the Pipe Section. These gaskets
are lubricated and help seal Pipe Sections as
they are connected together. If your O-ring
gasket is missing or it becomes unseated
during connection, you must replace and
