3. Operating Instructions
Your Suburban water heater offers both gas and electric heating options for your convenience.
3.1 Gas Operation (12V DC Ignition)
To operate using gas, ensure your propane supply is open. The 12V DC ignition system will automatically light the burner when hot water is demanded. This system provides rapid heating.
3.2 Electric Operation (120V AC with 12V Relay)
For electric heating, ensure your RV is connected to a 120V AC power source. The 12V relay allows for interior operation of the electric heating element. This option is ideal when shore power is available.
3.3 Temperature Control
The water heater is designed to maintain a maximum temperature of 120 degrees Fahrenheit. Temperature settings can be adjusted via the interior control panel.
4. Maintenance
Regular maintenance ensures the longevity and efficiency of your water heater.
4.1 Anode Rod Inspection and Replacement
The porcelain-lined steel tank is protected by an anode rod, which absorbs corrosive elements in the water. Inspect the anode rod annually and replace it when it has corroded to approximately 1/4 inch in diameter. Always drain the water heater before inspecting or replacing the anode rod.
