Check for any leaks in pipes. Ensure all tools are in good condition. Follow the manufacturer’s instructions carefully. Safety is very important during installation.

Removing The Old Water Heater

First, turn off the main water supply. Open a hot water faucet to release pressure. Locate the drain valve on your water heater. Attach a garden hose to the drain valve. Place the other end of the hose outside or into a drain. Open the drain valve to let the water flow out. Make sure to keep the faucet open to allow air to enter the tank. This will speed up the draining process. Once the water stops flowing, close the valve.

Ensure the power supply is turned off. This step is crucial to avoid any electrical hazards. Disconnect the power lines from the heater. These are usually found at the back of the unit. Use a wrench to loosen the water lines. Carefully detach them from the heater. Be prepared for some water to spill out. Wipe up any water to prevent slipping hazards.

Installing The New Tankless Heater

Find a suitable spot on the wall. The spot should be near the water source. Use a level to make sure it is straight. Mark the drill holes with a pencil. Drill the holes for the mounting screws. Attach the mounting bracket securely. Lift the tankless heater onto the bracket. Double-check that it is secure.

Shut off the main water supply. Connect the cold water line to the inlet. Use a wrench to tighten the connection. Connect the hot water line to the outlet. Make sure there are no leaks. Use Teflon tape to seal the connections. Turn the water supply back on. Check all connections for leaks.

Electrical And Gas Connections

Connect the heater to the power supply. Use proper wiring and connectors. Follow the manufacturer’s instructions. Always turn off the main power before starting. Ensure the heater has a ground wire. Check all connections for safety. Use a voltage tester to confirm no power. Label all wires clearly. Secure the wires to avoid damage.

Attach the gas line to the heater. Use a wrench to tighten the connections. Apply pipe sealant to prevent leaks. Check for any gas leaks with a soapy water solution. Ensure the gas valve is off before starting. Follow local safety codes and regulations. Vent the heater properly to avoid hazards. Ensure the gas line is the correct size.

Testing The Installation

Turn on the water supply to the RV. Look closely at the water connections. Watch for any drips or puddles. If you see any leaks, tighten the connections. Use a wrench carefully. Check the gas connections next. Smell for gas leaks. If you smell gas, turn off the supply. Call a professional for help.

Turn on a hot water tap inside the RV. Wait for the water to heat up. Make sure the water gets hot quickly. Listen for any strange noises from the heater. The water should flow smoothly and steadily. Test different taps in the RV. Ensure they all provide hot water. Adjust the temperature settings as needed. Confirm that the heater maintains a consistent temperature.

Maintenance Tips

Clean the heater every three months. Use a soft cloth for cleaning. This prevents dirt buildup. Check the filters and clean them as well. Dirty filters can cause problems. Rinse the filters with water. Make sure they are dry before putting them back.

Inspect the heater before winter and summer. Look for any leaks or damage. Make sure all connections are tight. Test the heating system to ensure it works. Replace any worn-out parts. Check the ventilation system to avoid blockages. Ensure the exhaust pipe is clear.

Troubleshooting Common Issues

Check if the propane supply is turned on. Ensure the water heater is receiving power. Inspect the water flow rate; it should meet the minimum requirement. If the water flow is too low, the heater won’t activate. Clean any clogged filters or aerators. Examine the temperature settings on the unit. Make sure they are set correctly. Lastly, check for air pockets in the water lines. Bleed the lines if necessary.

Refer to the user manual for specific error codes. Each error code indicates a different issue. Common error codes might include E1, E2, or E3. An E1 error usually means a problem with ignition. Check the propane supply and ignition components. An E2 error often relates to overheating. Ensure there is proper ventilation around the unit. An E3 error might indicate water flow issues. Verify that the water pressure is adequate. Reset the unit after fixing the issue. If problems persist, contact customer support.
