- If using a 3 B-Vent, attach the spacer. If using a 4 B-Vent, use another gasket and spacer.
- Insert the polypropylene pipe into the B-Vent, ensuring that the marked point and B-Vent end are approximately in the same position. Apply Centrocerin to the O-ring of the female side of the polypropylene pipe.
- Attach the base junction support to the B-Vent using screws. Make sure the spacer is fixed properly to prevent the polypropylene pipe from falling down.
