Features & Specifications
What is the primary function of the Gas Hot Water System MKII?
The Gas Hot Water System MKII is a portable, tankless water heater designed to provide instant hot water (up to 6 L/min) in outdoor and off-grid environments. It is ideal for camping, caravanning, remote showering, washing dishes, and general cleaning. It is designed for outdoor use only and must not be operated in any enclosed space.
What is the main upgrade in the MKII version of the Gas Hot Water System?
The most significant upgrade is the new tool-free quick-connect gas fitting. This allows you to connect the gas hose to the unit with a simple push-and-click action, eliminating the need for spanners and reducing the risk of over or under-tightening the connection. This makes setup faster, easier, and safer.
What are the key safety features of the Gas Hot Water System MKII?
The system is Gas Safe certified to Australian standards and includes a multi-layer safety system:
- Flame Failure Protection: Automatically cuts the gas supply if the burner flame is extinguished.
- Over-Temperature Cut-Off: Shuts the unit down if the outlet water temperature exceeds 50°C to prevent scalding.
- Anti-Dry-Burn Protection: The burner will not ignite unless sufficient water flow (min. 0.25 MPa pressure) is detected, protecting the heat exchanger from damage.

Installation & Setup
What else do I need to operate the Gas Hot Water System MKII?
The Gas Hot Water System MKII is comprehensive, but you will need to provide:
- An approved LPG gas cylinder with an LCC27 valve.
- A water supply, which can be mains pressure or a 12V water pump (like the KickAss 6L/min Pump) pulling from a water supply.
How and where should I mount the Gas Hot Water System MKII?
WARNING: This appliance is for outdoor use only. Never operate in an enclosed space.
Mount the unit vertically on a sturdy, non-combustible surface using the top and bottom brackets. Ensure the following minimum clearances:
- 1 metre above the top flue exhaust.
- 500mm from all sides.
The area must be well-ventilated and protected from direct rain. Use the included rain deflector on the top flue for weather protection.
How do I perform a gas leak check?
WARNING: This test must be performed before first use and every time you change the gas bottle. Never use an open flame to check for leaks.
- Ensure the unit main power switch is set to OFF.
- Connect the regulator to the gas bottle and the quick-connect hose to the unit.
- Prepare a 50/50 solution of liquid soap and water.
- Slowly open the valve on the gas cylinder.
- Apply the soapy solution to all gas connection points (at the bottle and at the unit).
- Look for growing bubbles. If you see bubbles, immediately turn the gas cylinder valve off, re-check the connection, and re-test. Do not use the unit if a leak persists.
Usage & Operation
How do I start up the Gas Hot Water System MKII?
- Confirm all gas and water lines are securely connected and a leak check has been performed.
- Turn on your water supply (pump or tap).
- Open the gas valve on the cylinder completely.
- Flick the Main Power Switch and the Battery Slot Switch on the bottom of the unit to ON.
- Set the flow switch on the shower head to ON.
- The unit will automatically ignite as soon as it detects sufficient water flow. Then the digital display will show the water temperature and battery life.
How do I adjust the water temperature of the Gas Hot Water System MKII?
Temperature is controlled by the three dials on the front panel:
- Gas Flow Knob: Turn towards MAX for a more intense flame and hotter water.
- Water Flow Knob: Turn towards MIN to slow the water flow, allowing it to heat up more as it passes through the system. A slower flow results in hotter water.
- Burner Regulation Knob: Use "Summer" mode to activate one burner row for milder temperatures, or "Winter" mode to activate all three rows for maximum heating power.
Note: For very cold water sources, you may need to cycle the water into a separate container first to pre-heat it.
How do I safely shut down the Gas Hot Water System MKII?
Follow these steps in order for a safe shutdown:
- Turn off both the main power switch and the battery switch on the unit.
- Completely close the gas supply valve on the LPG cylinder.
- Turn off your water supply source (12V pump or tap).
- Open the shower head switch to release any residual water pressure.
- Disconnect all hoses and allow the unit to drain and cool completely before storing.
Troubleshooting & Maintenance
The Gas Hot Water System MKII isn't igniting. What should I check?
If the igniter of the Gas Hot Water System MKII does not click, check the following:
- Ensure the main power switch on the bottom of the unit is in the ON position.
- Verify the 2 x D-cell batteries are new and installed with the correct polarity.
- Confirm your water source provides at least 0.25 MPa of sustained pressure. A weak pump or low mains pressure will prevent the ignition sensor from activating.
Why does the Gas Hot Water System MKII shut down suddenly during use?
The system may shut down when a safety feature is triggered:
- Over-Temperature Cut-Off: If the water exceeds 50°C, the system may shut down due to insufficient water flow for the selected gas setting. Increase the water flow or reduce the gas flow to help prevent overheating.
- Flame Blow-Out: Strong wind can extinguish the flame, triggering the flame failure sensor to shut off the gas. Reposition the unit out of direct wind.
- Water Pressure Drop: If the pump stops or the water supply runs out, the anti-dry-burn protection cuts off the gas supply to protect the unit.
How do I prepare the Gas Hot Water System MKII for winter storage?
To prevent permanent damage from freezing temperatures, the Gas Hot Water System MKII must be completely drained before storage.
- Disconnect all hoses and allow water to drain out of the water inlet and outlet.
- Store the unit upright in a dry, protected location and for long-term storage, remove the D-cell batteries to prevent corrosion.
Any water left inside the unit may freeze and expand, potentially rupturing internal pipes. Damage caused by freezing is not covered by warranty.
