Raypak R335A/335B Metal Head Flue Collector (005309F)

Raypak R335A/335B Metal Head Flue Collector (005309F) is a Raypak replacement metal head flue collector for R335A/335B heater applications. This item is best used when the original component is damaged, deteriorated, missing, or no longer performing correctly. Because many Raypak heater parts look similar across model families, the safest ordering approach is to match the complete part number 005309F, the heater model, and any ignition, voltage, fuel, or cabinet details shown on the existing unit.

This component helps replace a worn or damaged original component as part of a larger heater rebuild. Venting and flue components help route exhaust correctly and should be inspected with the surrounding vent system. Always compare the part number, model family, and heater configuration before ordering, especially on older Raypak units with similar model names. For heater repairs, installation should follow the manufacturer service procedure and local code requirements. Before replacing the part, inspect nearby gaskets, fasteners, wiring, headers, combustion components, and venting surfaces so the repair does not leave a related failure point unresolved.
