The Furrion FWH09AFA-AM is a 2.4 GPM propane tankless RV water heater. Its manufacturer exploded illustration identifies internal service parts by letter, from the water filter and drain plug through the flow sensor, controller and heat exchanger. This reference matches those letters to Lippert's original service numbers and the NewRVParts replacements that can be verified by both numbering systems.

Confirm the correct system or model
Check the complete FWH09AFA-AM label before selecting a service part. The FWH09A and FWH09AFA models share many parts, but the manufacturer's drawing also includes special door or drain components for flangeless variants. Those variant-only items are not presented here as replacements for the standard FWH09AFA-AM.
The filter, drainpipe plug and water-flow sensor are individual service parts; they are not included together with a replacement water heater. The original manual identifies them as Lippert 2021124180, 2021124309 and 2021124288, respectively, and Lippert separately cross-references the matching Furrion C-FWH09A numbers. Retrofit access doors are listed separately and must be selected for the RV's existing opening and the correct heater/door configuration.
