Venti P4D03VKC Concentric Vent Cap 3 Inches

Product Description

The VENTI P4D03VKC is a 3-inch concentric vent cap designed for sealed combustion and direct-vent heating systems. It serves as the exterior termination point for concentric vent assemblies, combining the combustion air intake and flue exhaust into a single through-wall or through-roof fitting. Licensed HVAC technicians install this cap during new equipment commissioning or as a field replacement when an existing termination is damaged, missing, or non-compliant with current clearance requirements. The 3-inch diameter fits concentric vent pipe systems common in residential and light commercial gas appliance installations.

The P4D03VKC is suited for direct-vent furnaces, boilers, and water heaters that use a concentric venting configuration. This setup draws outdoor combustion air through the outer annular passage while exhausting flue gases through the inner pipe, all through a single penetration in the building envelope. This cap mounts at the exterior wall or roof termination point, providing weather protection and proper airflow separation for both the intake and exhaust streams.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with the appliance manufacturer instructions and applicable mechanical codes, including IFGC requirements for vent termination clearances. Shut down and de-energize the appliance before servicing or replacing any vent components. Ensure the termination location meets all required clearances from windows, doors, gas meters, and electrical equipment as specified by local authority having jurisdiction. Seal all wall or roof penetrations appropriately to prevent air infiltration or moisture intrusion.
