INTERIOR VENT INSTALLATION
This kind of installation provides the natural draft that results
from a vertical rise avoiding smoke being released into the house
when electricity to the unit is interrupted while burning or smold-
ering pellets remains in the burn grate.
General vent layout is shown in figure and the procedure is as fol-
lows:
- General vent layout is shown in figure and the procedure is as
follows: !da duplicazione!
- use a plumb line to determine location of PL Vent penetration
of ceiling
- cut hole in ceiling and frame to appropriate opening size. Fram-
ing material shall be the same as that of adjacent joist material
- install a black ceiling support from under the level of the beam
and fix using 4 twisted nails or screws, 1.5" (40 mm). Alternative-
ly, use a support attachment instead of a black ceiling support.
The attachment is suitable for openings in the ceiling from be-
low and is fixed to the beams with 4 twisted nails or screws, 1.5"
(40 mm)
- insert first vent section through support and tighten the clamp
screw. Additionally fasten the vent with four screw (max 1/2"
(13 mm) long) through the support collar and into the vent skin
- install the vent section(s) atop the first. Twist lock sections to-
gether with a clock-wise turn. Before twisting, push vent sec-
tions firmly together for proper lock barb engagement. Enough
twisting force must be applied to ensure that the collars will
compress gasket material
- firestops are required where the vent penetrates a floor or ceil-
ing. Cut a hole of the appropriate size in the ceiling/floor and
install the firestop from above or below the joist. Fasten the
firestop with nails through the corners
- continue the vent up through the roof line
- extend the vent up to the roof pitch
- slide the Flashing over the Vent until it sits on the roof line. Slip
the upper side of the Flashing base under the roof shingles. Nail
the flashing to the roof with a minimum of 8 roofing nails. Seals
the Flashing base with appropriate roofing mastic
- slide the Storm Collar down the Vent until it sits on the flashing.
Apply a bead of silicone around the top of the Storm Collar

- extend the PL Vent at least 12" (30 cm) above the roof line and
terminate with a PL listed Rain Cap. If the Vent extends more
than 6' (2 m) above the roof penetration, Roof Brace Poles and a
Roof Brace Band must be used to provide lateral support. In ge-
ographical regions experiencing sustained low ambient tem-
perature is recommended to enclose exterior vents below the
roof line. This help reduce condensation, soot accumulation,
and poor drafting
- set the Rain Cap onto the top Vent section and twist lock it to
the top Vent section
- where the vent system penetrates the air/vapor barrier, the bar-
rier must be sealed to the ceiling support or firestop.
