- Cut hole in ceiling and frame to appropriate opening size. Framing material shall be the
same as that of adjacent joist material.
- Install Black Ceiling Support from below joist level and fasten with 4–1.5" (102 mm - 38
mm) spiral nails or screws (Fig. 10). Alternatively, a Support Assembly may be used in place
of the black ceiling support the support assembly fits to ceiling opening from below and is
fastened to joists with 4 -1.5" (102 mm - 38 mm) spiral nails or screws (Fig.10).
- Insert first Vent section through Support and tighten the clamp screw. Additionally fasten
the vent with four screw (max ½" / 12mm long) through the support collar and into the vent
skin.
- Install the vent section(s) atop the first. Twist lock sections together with a clock-wise turn.
Before twisting, push vent sections 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 ceiling. 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 (Fig. 10).
- Elbows may be used to offset the Vent as necessary to jog around joists or rafters. Keep use
of elbows to a minimum as they reduce drafts capacity of a vent.
- Continue the Vent up through the roof line.
- 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 (Fig. 11). If the Vent extends more than 6' above the roof penetration, Roof Brace
Poles and a Roof Brace Band must be used to provide lateral support. In geographical
regions experiencing sustained low ambient temperature 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 (Fig.11).
- Where the vent system penetrates the air/vapor barrier, the barrier must be sealed to the
ceiling support or firestop.
Warning!
Be sure to use approved pellet vent pipe and ceiling pass through fittings to go through
combustible ceilings.
Strictly observe the PL Vent manufacturer's safety specifications when using ceiling pass
through.
Install vent at clearances specified by the vent manufacturer.
Ensure that all installation work is carried out to professional standards.
