Setup and Installation
Proper installation is crucial for safe and efficient operation. It is recommended that installation be performed by a qualified RV technician.
Pre-Installation Checks
- Verify that the water heater model matches your RV's requirements.
- Ensure adequate clearance for ventilation and maintenance access.
- Inspect the unit for any shipping damage.
Water Connections
- Connect the cold water inlet and hot water outlet lines to the designated ports on the water heater. Use appropriate plumbing fittings and sealants to prevent leaks.
- Ensure all connections are tight but do not overtighten.
Gas Connections
- Connect the RV's LP gas supply line to the water heater's gas inlet.
- Use gas-rated sealant on threaded connections.
- After connection, perform a leak test using a non-corrosive leak detection solution.
Electrical Connections
- Connect the 12VDC wiring for the Direct Spark Ignition system and the 12VDC relay according to the wiring diagram provided with the unit.
- If utilizing the electric heating element, connect the 120VAC power supply to the designated terminals. Ensure proper grounding.
- All electrical work should comply with local codes and standards.
Filling the Water Heater Tank
- Close the drain valve (anode rod).
- Open all hot water faucets inside the RV.
- Turn on the RV's main water supply.
- Allow water to flow from the hot water faucets until all air is purged and a steady stream of water is present.
- Close the hot water faucets. The tank is now full.
Operating Instructions
Ensure the water heater tank is full before operating on either gas or electric power.
Gas Operation (Direct Spark Ignition)
- Ensure the LP gas supply is turned on at the tank.
- Locate the interior wall switch for the gas water heater.
- Flip the switch to the 'ON' position. The DSI system will attempt to ignite the burner.
- If ignition is successful, the 'FAULT' light (if present) will turn off. If ignition fails after several attempts, the 'FAULT' light will illuminate. Turn the switch 'OFF' for 5 minutes, then try again.
Electric Operation
- Ensure the RV is connected to a 120VAC power source (shore power or generator).
- Locate the exterior switch for the electric heating element, typically behind the water heater access panel.
- Flip the exterior switch to the 'ON' position.
- Some models may also have an interior switch for electric operation. Ensure both are 'ON' if applicable.
Simultaneous Operation
For faster recovery or higher hot water demand, both the gas and electric heating elements can be operated simultaneously.
Safety Precautions
- Never operate the water heater with an empty tank.
- Do not store flammable materials near the water heater.
- Ensure proper ventilation for gas operation.

Maintenance
Regular maintenance ensures optimal performance and extends the life of your water heater.
Anode Rod Inspection and Replacement
The anode rod protects the tank from corrosion. It should be inspected annually and replaced when 75% consumed.
- Turn off all power to the water heater (gas and electric).
- Turn off the RV's main water supply.
- Open a hot water faucet inside the RV to relieve pressure.
- Carefully remove the anode rod (which also serves as the drain plug) using a 1 1/16-inch socket. Be prepared for water to drain.
- Inspect the rod. If it is heavily pitted or less than 1/4 inch in diameter at any point, replace it with a new Suburban anode rod.
- Flush the tank with fresh water to remove sediment.
- Install the new anode rod (or the old one if still good) with plumber's tape on the threads.

Draining the Tank
Drain the tank whenever the RV will be stored or if there is a risk of freezing temperatures.
- Follow steps 1-3 from anode rod removal.
- Remove the anode rod to allow the tank to drain completely.
- Open the pressure relief valve to assist draining.
- Once drained, replace the anode rod (or drain plug) and close the pressure relief valve.
Winterization
To prevent damage from freezing, the water heater must be properly winterized.
- Drain the water heater tank completely as described above.
- Bypass the water heater using the bypass valves (if installed) to prevent antifreeze from entering the tank.
- Pump RV-approved non-toxic antifreeze into the RV's plumbing system.
- Do not put automotive antifreeze into the fresh water system.

Troubleshooting
This section addresses common issues. For complex problems, consult a qualified technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water (Gas) | No LP gas, faulty DSI, thermostat issue, air in gas line. | Check LP gas supply. Turn gas switch OFF for 5 minutes, then ON. Purge air from gas lines by operating other gas appliances. Consult technician if DSI fault persists. |
| No hot water (Electric) | No 120VAC power, electric element switch off, tripped breaker, faulty element. | Check shore power/generator. Ensure exterior and interior electric switches are ON. Reset circuit breaker. Consult technician for element replacement. |
| Water leaks | Loose connections, faulty pressure relief valve, cracked tank. | Tighten connections. Inspect pressure relief valve. A cracked tank requires replacement. |
| Low hot water temperature | Thermostat setting, excessive hot water use, sediment buildup. | Ensure thermostat is set correctly. Allow recovery time. Drain and flush tank to remove sediment. |
