Maintenance & Service
To keep the RU199iN running efficiently and protect its warranty, regular maintenance is crucial:
-
Flush/descale the heat exchanger every 3–5 years (more often if water is hard)
-
Annually check vents and filters, inspect condensate drain, verify gas pressure and ignition system
-
Only professional installers (like 4Most Energy) ensure proper venting, gas pressure and installation quality — incorrect install is the most common cause of early failure.
