Maintenance Tips
-
Annual Flush & Drain: Drain and flush the tank every 6–12 months to remove sediment and maintain heating efficiency.
-
Inspect Anode Rod: Check the anode rod regularly and replace it when significantly corroded to prevent tank rust and extend service life; it also doubles as the drain plug.
-
Clean Burner & Vent: Keep the burner area, vent openings, and combustion chamber clear of dirt, debris, and insect nests to ensure proper airflow and safe flame operation.
-
Check Electrical Components: Inspect the electric heating element, wiring, and thermostat for signs of wear or damage; tighten connections and replace faulty parts.
-
Test Pressure Relief Valve: Lift and release the pressure‑temperature relief valve annually to confirm it opens freely and reseals properly, preventing overpressure issues.
-
Gas & Power Safety: Always turn off LP gas and electric power before performing any maintenance; use soapy water to test gas connections for leaks.
-
Professional Service: Schedule a yearly inspection by a qualified RV technician to check direct spark ignition, controls, and gas safety systems.
