5. Setup and Installation

The VEVOR 18L LPG Gas Water Heater is designed for wall-mounted installation, making it space-saving and suitable for various environments. It is crucial to follow all safety guidelines and local regulations during installation.

5.1. Choosing an Installation Location

• Install the unit in a well-ventilated area, preferably outdoors or in a location where toxic gas leakage during bathing is not a risk (e.g., machine in kitchen, shower in bathroom).
• Ensure the mounting surface is sturdy enough to support the weight of the water heater.
• Keep the unit away from flammable materials and direct sunlight.
• Ensure easy access for maintenance and operation.

5.2. Mounting the Unit

• Use the back screw holes and mounting brackets provided on the unit to securely attach it to the wall.
• Ensure the unit is level and firmly fixed to prevent movement.

5.3. Connecting Water and Gas

• Water Connections: Connect the water inlet and outlet using standard G1/2" copper pipe connectors. Ensure all connections are tight and leak-free. The connectors include a filtration mesh to prevent impurities from entering the system.
• Gas Connection: Connect the LPG gas supply to the unit using a φ 0.79" rubber gas hose. Verify that the gas type is LPG (Propane/Butane) and not methane. Perform a leak test on all gas connections using soapy water.
• Exhaust Pipe: Connect a φ 4.5" smoke exhaust pipe (not included) to the top outlet of the water heater. Ensure proper sealing and ventilation.

5.4. Battery Installation

• Locate the battery compartment at the bottom of the unit.
• Insert two (2) 1.5V D-Type batteries (not included) into the compartment, ensuring correct polarity. These batteries power the automatic ignition system.

6. Operating Instructions

The VEVOR LPG Gas Water Heater features an intuitive control panel for easy temperature adjustment and mode selection.

6.1. Control Panel Overview

• LED Display: Shows the real-time water temperature.
• Gas Regulator Knob: Rotate clockwise to increase gas supply and heat output.
• Water Regulator Knob: Rotate clockwise to increase water flow.
• Winter/Summer Mode Switch: Select the appropriate mode to optimize gas consumption based on ambient temperature. Winter mode provides higher heat output, while Summer mode uses lower fire power to save gas.

6.2. Starting the Water Heater

1. Ensure the gas supply is open and water connections are secure.
2. Open a hot water tap. The water heater will automatically ignite.
3. The LED display will show the current water temperature.

6.3. Adjusting Water Temperature

• Use the Gas Regulator Knob to adjust the flame intensity, which directly affects the water temperature.
• Use the Water Regulator Knob to control the water flow rate. A lower flow rate generally results in hotter water, and vice versa.
• Select Winter Mode for higher heat output in colder conditions or when higher temperatures are desired.
• Select Summer Mode for lower heat output in warmer conditions or to save gas.

6.4. Low Water Pressure Start

The water heater is designed to operate even with low water pressure, requiring only 0.015 MPA to initiate ignition.

7. Maintenance

Regular maintenance ensures the longevity and safe operation of your water heater.

• Cleaning: Periodically wipe the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners.
• Connection Checks: Regularly inspect all water and gas connections for leaks or corrosion. Tighten any loose connections.
• Battery Replacement: Replace the D-type batteries when the ignition becomes weak or fails.
• Anti-Frozen Protection: In cold climates, ensure the anti-frozen protection system is functioning correctly or take measures to drain the unit if it will be exposed to freezing temperatures for extended periods.
• Exhaust System: Ensure the exhaust pipe is clear of obstructions and properly sealed.

8. Troubleshooting

If you encounter issues with your water heater, refer to the following common problems and solutions:

• No Hot Water:
  • Check if the gas supply is open and the gas tank has sufficient fuel.
  • Verify that the D-type batteries are installed correctly and have enough power.
  • Ensure water pressure is within the suitable range (0.02 MPA - 0.8 MPA).
  • Check for any obstructions in the water inlet filter.
• Water Not Hot Enough:
  • Adjust the Gas Regulator Knob to increase gas flow.
  • Reduce the Water Regulator Knob to decrease water flow, allowing more time for heating.
  • Ensure the unit is in Winter Mode if operating in cold conditions.
• Unit Shuts Off Unexpectedly:
  • This could be due to safety features activating. Check for overheating (water temperature exceeding 75℃), low water flow, or flame failure.
  • Ensure proper ventilation to prevent carbon monoxide buildup.
  • If the 20-minute timer activates, the unit will shut off. Restart if needed.
• Gas Leak Smell:
  • Immediately turn off the gas supply.
  • Open windows and doors for ventilation.
  • Do not operate any electrical switches or create sparks.
  • Contact a qualified professional for inspection and repair.

9. User Tips

• Outdoor Use: This tankless water heater is excellent for outdoor activities like camping, RV showering, or pet washing. Always ensure it's placed on a stable surface and protected from direct weather elements.
• Water Flow vs. Temperature: For hotter water, slightly reduce the water flow using the water regulator knob. For cooler water, increase the flow.
• Gas Efficiency: Utilize the Summer/Winter mode switch to optimize gas consumption. Use Summer mode when ambient temperatures are higher to save LPG.
• Pre-check: Before each use, especially after periods of inactivity, quickly check gas and water connections for any signs of leakage or damage.
