Maintenance Tips 

• Descale yearly (or every 6–12 months in hard water areas) using a flush kit to prevent mineral buildup and flow issues.
• Clean inlet water filter regularly to maintain strong water flow and avoid ignition errors.
• Inspect venting area & exterior unit every few months—remove dust, debris, insects, and ensure clear airflow.
• Check gas connection & water lines for leaks, corrosion, or loose fittings before peak usage seasons.
• Maintain freeze protection: drain and winterize in freezing conditions if not in use (even with outdoor models).
• Set temperature ~120°F for safer operation and reduced scaling inside the heat exchanger.
• Power cycle & reset if errors occur after maintenance or low-flow conditions.
• Annual professional inspection recommended for burner, sensors, and gas pressure calibration.
