Maintenance Tips        

• Flush the unit every 6–12 months to remove mineral scale and maintain heating efficiency
• Clean the inlet water filter regularly to prevent flow restriction and ignition issues
• Check gas line connections for leaks, corrosion, or looseness before operation
• Ensure outdoor installation area stays clear of debris for proper airflow and safe exhaust discharge
• Inspect vent-free exhaust outlet and freeze protection system for proper function
• Descale heat exchanger in hard water areas to maintain stable temperature output
• Maintain proper water pressure (avoid low flow or unstable temperature swings)
• Keep exterior casing clean and free from dust, insects, and moisture buildup
• Inspect temperature sensors and digital display for error codes and address early
• Do not use for hydronic heating, floor heating, or recirculating systems
• Shut off gas and water supply before performing any maintenance
• Schedule professional servicing every 12 months for safety and long-term reliability
