Maintenance Tips    
  • Install indoors with proper 3" venting (horizontal/vertical kit) and ensure all joints are fully sealed to prevent CO leakage and performance loss.
  • Perform annual descaling/flush (EZ-Flush kit recommended) to prevent mineral buildup and maintain stable 4.5 GPM flow and heat exchanger efficiency.
  • Keep inlet water pressure steady at 50–80 PSI for consistent ignition and temperature control.
  • Clean the inlet water filter regularly to avoid flow restriction, error codes, and ignition delays.
  • Ensure stable natural gas supply (15,000–80,000 BTU range) to prevent shutdowns or temperature fluctuations.
  • Inspect venting system yearly for blockages, condensation buildup, or loose connections, especially in dusty environments.
  • Use the Smart App (WiFi/Alexa/Google integration) to monitor temperature, error codes, and maintenance alerts in real time.
  • Flush immediately if you notice temperature swings or reduced flow, as scale buildup is the most common issue.
  • Keep unit exterior clean and dust-free around air intake and control panel to maintain proper airflow and combustion stability.
  • Because this is a scratch & dent unit, inspect casing, seals, and mounting points more frequently for hidden damage that could affect safety or sealing integrity.
