Maintenance Tips    

• Descale every 6–12 months to prevent mineral buildup and maintain consistent hot-water flow
• Clean inlet water filter regularly to avoid low-pressure shutdowns and ignition issues
• Check venting system (4” indoor exhaust) for blockages, leaks, or condensation buildup for safe operation
• Inspect propane connections & regulator for leaks, pressure stability, and secure fittings
• Keep temperature around 120°F to reduce scaling and improve energy efficiency
• Ensure proper indoor clearance & airflow to prevent overheating and error codes
• Flush system before peak usage seasons for stable performance, especially in hard water areas
• Test ignition system & error codes periodically to catch early faults
• Use manufacturer-approved flush kit for safe descaling and longer heat exchanger life
• Schedule annual professional inspection for burner, gas pressure, and safety components
