5. Setup
Follow these steps for proper installation and initial setup:
- Mounting: Fix a screw securely into a wall or sturdy vertical surface. The unit can be hung using its portable handle or the mounting bracket on the back. Ensure the location is well-ventilated and protected from direct rain if possible.
- Hang Water Heater: Carefully hang the water heater unit onto the fixed screw.
- Battery Installation: Open the battery compartment and install two 'D' cell batteries. Ensure correct polarity.
- Water Connections:
- Connect the water inlet hose (typically cold water supply) to the designated inlet port on the water heater. Use Teflon tape on threads for a watertight seal.
- Connect the shower head hose to the water outlet port.
- Gas Connection: Connect the gas regulator hose to a propane tank. The gas pipe on the unit is pre-connected to the gas inlet. Ensure all gas connections are tight and check for leaks using a soapy water solution.
- Check for Leaks: Before turning on the gas, open the water supply and check all water connections for leaks. Then, with the gas supply open, apply a soapy water solution to all gas connections. Bubbles indicate a leak; tighten connections until no bubbles appear.

6. Operating Instructions
Once the unit is properly set up and all connections are secure:
- Open Water Supply: Turn on the cold water supply to the water heater. Ensure water is flowing through the unit. The water heater requires a minimum of 3 PSI water pressure to activate.
- Open Gas Supply: Slowly open the valve on your propane tank.
- Adjust Controls: Use the control knobs on the front panel to adjust gas flow (heat) and water flow to achieve your desired temperature. The LED display will show the current water temperature.
- Select Season Mode: The unit features a Winter/Summer switch. Select the appropriate mode for optimal performance based on ambient temperature.
- Ignition: The unit will automatically ignite when water flow is detected and the gas supply is open. You should hear a clicking sound followed by the burner igniting.
- Enjoy Hot Water: Hot water will be delivered instantly. Adjust the knobs as needed for comfort.
- Shut Down: To turn off, first close the gas supply valve on the propane tank, then turn off the water supply.

7. Maintenance
Regular maintenance ensures the longevity and safe operation of your water heater.
- Cleaning: Periodically clean the exterior of the unit with a damp cloth. Do not use abrasive cleaners or solvents.
- Check Connections: Regularly inspect all gas and water connections for leaks or wear. Replace any worn hoses or fittings immediately.
- Battery Replacement: Replace the 'D' cell batteries when the ignition becomes weak or fails to ignite consistently.
- Winterization (Anti-Freezing Protection): If using in freezing temperatures, ensure the unit is completely drained of water after each use to prevent damage from freezing. The unit has built-in anti-freezing protection, but manual draining is recommended for prolonged storage in cold conditions.
- Storage: When not in use for extended periods, disconnect the propane tank, drain all water from the unit, remove batteries, and store in a dry, protected area.
8. Troubleshooting
If you encounter issues, refer to the following common troubleshooting steps:
- No Hot Water / Unit Not Igniting:
- Check if the propane tank is open and has sufficient fuel.
- Ensure water supply is open and water pressure meets the minimum 3 PSI requirement.
- Verify batteries are correctly installed and have sufficient charge. Replace if necessary.
- Check all gas and water connections for leaks.
- Water Not Hot Enough:
- Increase the gas flow using the control knob.
- Decrease the water flow using the control knob.
- Ensure the season switch is set appropriately (e.g., Winter mode for colder ambient temperatures).
- Unit Shuts Off During Use:
- This could be due to a safety feature activation (e.g., overheat, low water flow, flame failure). Check for obstructions in water flow, ensure adequate ventilation, and verify gas supply.
- Ensure the unit is not tipping, as anti-tipping protection may activate.
9. User Tips
- For optimal performance, use a consistent water pressure source.
- Always have spare 'D' cell batteries on hand, especially for extended trips.
- Consider using a small bucket or basin to catch initial cold water while waiting for hot water to arrive, conserving water.
- When adjusting temperature, make small changes to the gas and water flow knobs and allow a few seconds for the temperature to stabilize.
