Raypak D-2 331-407 Flue Box (008683F)

The Raypak D-2 331-407 Flue Box is a replacement flue box intended for use with compatible Raypak D-2 331-407 equipment. It is designed for repair situations where the original part is damaged, worn, corroded, cracked, missing, or no longer fitting as it should. This component is used for helping manage combustion airflow, exhaust routing, heat movement, or draft control within the heater cabinet. Because heater and pool equipment parts are often model-specific, matching the manufacturer part number 008683F is the safest way to confirm compatibility before installation.

These parts are typically replaced when the original component is deteriorated, heat damaged, missing, or no longer positioned correctly. This replacement is best suited for service technicians, maintenance teams, and pool owners who are restoring an existing system rather than replacing the full unit. Confirm the heater model, orientation, and exhaust configuration before ordering, since similar Raypak parts can vary by BTU range and series. Review the equipment label, installation manual, exploded parts diagram, and any markings on the original part before purchase.
