Westinghouse 663714R In-line Drain Assembly Furnace

Product Description

The WESTINGHOUSE 663714R is an in-line drain assembly designed for use with PVC-vented condensing gas furnaces. This component manages condensate drainage within the vent system, collecting and routing moisture produced during the combustion process away from the heat exchanger and flue. It is a direct replacement part intended for licensed HVAC technicians servicing residential gas furnace installations. Proper condensate management is critical to preventing water damage, vent blockages, and equipment faults in high-efficiency furnace systems.

This drain assembly is specified for use on WESTINGHOUSE G6RC and G6RL series furnaces configured in upflow, downflow, and horizontal orientations. It is an OEM-style replacement part suited for residential installations where the original in-line drain component has failed, cracked, or become obstructed. The part supports the condensate handling requirements of PVC-vented high-efficiency gas furnace applications across multiple installation orientations.

Key Features

• Compatible with upflow, downflow, and horizontal furnace orientations
• Designed for PVC vent system condensate drainage applications
• OEM-style replacement for the G6RC and G6RL furnace series
• Supports condensate removal from the flue vent path to protect system components

Compatibility

Designed for use with WESTINGHOUSE G6RC and G6RL series upflow, downflow, and horizontal configuration gas furnaces with PVC vent systems.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut off electrical power and gas supply to the furnace before removing or replacing any vent or drain components. Inspect all PVC vent joints and condensate lines during replacement to confirm proper sealing and slope for drainage. Refer to the furnace manufacturer installation manual and local mechanical codes for condensate disposal requirements.
