Raypak 183A Cast Iron Inlet/Outlet Header is a replacement heater component for compatible Raypak pool and spa heating systems. Heater parts must fit correctly because they operate around heat, combustion, water flow, ignition, and safety controls. This component is intended to help restore the heater assembly when the original part is damaged, corroded, worn, or no longer functioning as intended. Before ordering, compare the existing part and confirm the full heater model, fuel type where applicable, production details, and part number 002433F.Use this part as part of a proper heater diagnosis rather than a guess-based repair. Many heater issues involve more than one component, so inspect adjacent gaskets, fasteners, wiring, refractory material, burners, headers, and water-contact parts during service. Installation should be performed with power and gas shut off where applicable and in accordance with the equipment manual.
