3.3. Plumbing Connections
- Connect the cold water inlet to the designated port on the water heater.
- Connect the hot water outlet to your RV's hot water distribution system.
- Ensure all water connections are tight and use appropriate RV-grade plumbing fittings.
- Open all hot water faucets in the RV to purge air from the system once water supply is connected.
3.4. Gas Connections
- Connect the propane gas supply line to the gas inlet on the water heater.
- Use only approved gas fittings and ensure all connections are leak-tested with a suitable leak detection solution.
- Verify that the propane pressure is within the specified operating range for the appliance.
3.5. Electrical Connections
Connect the 12V DC power supply to the water heater's electrical terminals. Ensure correct polarity. The unit requires a stable 12V DC power source for operation of its control board and fan.

3.6. Initial Startup
- After all connections are made and checked, open the propane supply valve.
- Turn on the 12V DC power to the unit.
- Open a hot water faucet in the RV. The water heater should ignite and begin producing hot water.
- Allow water to run for a few minutes to ensure all air is purged from the gas line and water system.
4. Operating Instructions
The CONTOURE Tankless Water Heater operates on demand, meaning it only heats water when a hot water faucet is opened.
4.1. Turning On/Off
The unit is typically controlled by a switch located on the RV's control panel or directly on the water heater's internal control board (if accessible). Ensure the 12V DC power is supplied to the unit for operation.
4.2. Hot Water Delivery
To obtain hot water, simply open any hot water faucet in your RV. The water heater will sense the water flow and automatically ignite to heat the water to the desired temperature. Close the faucet to stop the heating process.
4.3. Dual Outlet Performance
This model supports dual outlet usage, allowing simultaneous hot water delivery to two fixtures. Performance may vary depending on the flow rate and desired temperature at each fixture.
4.4. Cold Weather Operation (Winterization)
During cold weather, it is crucial to properly winterize the water heater to prevent freezing and damage. Refer to the Maintenance section for detailed winterization procedures.
5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your water heater.
5.1. Exterior Cleaning
Clean the exterior access door and vents periodically with a mild detergent and soft cloth. Ensure vents are clear of obstructions.
5.2. Gas Line Inspection
Periodically inspect all gas connections and lines for leaks or damage. Use a leak detection solution to check for gas leaks at connections.
5.3. Water System Descaling
Depending on water hardness, mineral deposits can accumulate in the heat exchanger. Consult a qualified RV technician for periodic descaling to maintain efficiency. The frequency depends on water quality and usage.
5.4. Winterization Procedure
Before storing your RV in freezing temperatures, the water heater must be winterized:
- Turn off the propane supply and disconnect the 12V DC power to the water heater.
- Drain all water from the RV's plumbing system, including the water heater. Open the drain valve on the water heater (if present) or disconnect the cold water inlet to allow drainage.
- Ensure no water remains in the unit's heat exchanger or pipes.
- If using RV antifreeze, ensure it circulates through the hot water lines connected to the water heater.
6. Troubleshooting
This section provides solutions for common issues. If problems persist, contact a qualified service technician.
