The Fogatti Tankless Water Heater # LSB44FR maintenance section lists that you should drain the RV regularly flush the heat exchanger with an RV rated descaling solvent. They're very loose on their verbiage on "regularly" so at minimum you should do it once a season. to get the solvent through the water heater you would need to dump it into your gravity fill tank and run your water pump to pressurize the system and then run your hot water to pull it through the water heater.
