Maintenance Tips
-
Balance water chemistry: Keep pH and sanitizer within recommended ranges to protect the copper heat exchanger from corrosion and leaks (poor chemistry is a common cause of heat exchanger failure).
-
Maintain proper flow: Ensure filters are clean and the pump is set for correct GPM; low flow can trigger faults and stress internal components.
-
Inspect burners & combustion area: Remove debris and check ignition components regularly to ensure efficient combustion and prevent service faults.
-
Monitor digital controls & Wi-Fi: Use the integrated Raymote app to track performance, error codes, and schedule heating for efficient operation.
-
Protect from moisture intrusion: Keep the cabinet dry and clear of standing water to prevent corrosion of electronics and internal parts.
-
Check gas connections & pressure: Confirm secure propane fittings and correct pressure for safe, reliable ignition.
-
Annual professional service: Have a qualified technician inspect heat exchanger, valves, sensors, and safety switches before the heating season.
