Interior Vent Installation - Piazzetta P963 Instructions For Installation, Use And Maintenance Manual

1.8 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 smoldering pellets
remains in the burn grate.
General vent layout is shown in figure and the procedure is as follows:
- Position the appliance in desired location according to appliance
installation requirements.
- Use a plumb line to determine location of PL Vent penetration of
ceiling.
- 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" spiral nails or screws (Fig. 10). Alternatively, a Support Assembly
may be used in place of the black celing support the support assembly
fits to ceiling opening from below and is fastened to joists with 4 -
1.5" 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" 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" above the roof line and terminate with a
PL listed Rain Cap (Fig. 11). If the Vent extends more than 6' above the
roof penetreation, 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/vapour barrier, the barrier
must be sealed to the ceiling support or firestop.
a
Be sure to use approved pellet vent pipe and ceiling pass-
through fittings to go through combustible ceilings.
a
Strictly observe the PL Vent manufacturer's safety
specifications when using ceiling pass through.
