Furrion's FWH09AFA-AM is a propane-fired tankless RV water heater. Its removable inlet filter and drainpipe plug are different service parts, while the water-flow sensor, flue seal and wall controller have separate jobs. This reference connects the letters in Lippert's factory exploded drawing to replacement components listed on UsedRVParts.

Water and drainage
Filter maintenance, water drainage and water-flow detection are separate functions.
Exhaust / service seal
Exhaust sealing must be maintained in its specified position. Work on the combustion side should be handled by a qualified service technician.
User interface
The wall-mounted display/controller is a separate part from the internal freeze-detector control unit shown as callout A.

Model and service checks before ordering
In its service manual, Furrion identifies the inlet filter for periodic cleaning and the filter cover and drain plug as separate openings used in draining the unit. Shut off propane and electrical power, let the unit cool and release water pressure before any service. Never open a hot or pressurized drain. Follow the water-heater and RV manufacturer's winterizing directions.
Gas-system, exhaust, electrical-control and sealed-combustion work should be diagnosed and performed by qualified personnel. A replacement flow sensor is not proof that a water-flow complaint is caused by the sensor.
