• Flush the Tank Regularly: Drain and flush the water heater at least once a year to remove sediment buildup and improve heating efficiency.

• Check for Leaks: Periodically inspect all water and LP gas connections for tightness and any signs of leaking; tighten or repair as needed.

• Clear Vents & Combustion Areas: Keep the exterior vent and combustion chamber free of debris, insect nests, or blockages to ensure proper airflow and safe operation.

• Pressure Relief Valve: Verify the pressure-temperature (P&T) relief valve operates correctly; replace if it leaks excessively or binds.

• Professional Inspection: Have a qualified RV technician service the unit annually to check ignition, controls, and gas system safety.
