CHECKING FOR GAS LEAKS

• Please use the supplied regulator and hose.
• NEVER check for leaks with a flame or pilot light.
• To safely check for leaks, use the ‘soapy water’ method. Coat the connections with a thin layer of soapy water. If you see bubbles appear, turn the cylinder gas control off and retighten the connection before re-testing.
• Please check connections between the gas bottle and the gas hose and connections between the rubber and brass parts of the gas hose.
• Inspect the appliance regularly for signs of wear, leaks, or incorrect operation. If symptoms such as burner flares, lighting issues, hose or connection damage, or leaks from the seals or gas controls are identified, do not attempt to repair, contact customer service as soon as possible.

CHANGING GAS CYLINDER

• To check if gas remains in the cylinder, disconnect from the appliance and hold the cylinder in a vertical position, then shake from side to side. If there is a sound or feel of liquid movement inside, the cylinder contains gas.
• Gas containers shall be changed in a well-ventilated location, preferably outside away from people and any sources of ignition, such as naked flames, pilot flames, electric heaters/equipment.

CHOOSING LOCATION

This appliance must only be used in an above-ground open-air location with natural ventilation,without stagnant areas, where gas leakage can be rapidly dispersed by wind and natural convection.
The following figures show outdoor areas suitable for use with this appliance. Rectangular areas have been used in these figures – the same principles apply to any other shaped areas.
Any enclosure in which the appliance is used shall comply with one of the following:
a. An enclosure with walls on all sides, but with no overhead cover, such as:

b. Within a partial enclosure that includes an overhead cover and no more than two walls,such as:

c.Within a partial enclosure that includes an overhead cover and more than two walls, the following shall apply:

1. At least 25% of the total wall area is completely open.
2. 30% or more in total of the remaining wall area is open and unrestricted.
3. In the case of balconies, 20% or more of the total wall area shall remain open and unrestricted.
   For example:

PREPARING THE APPLIANCE

1. Find a sturdy, non-combustible vertical surface to hang the appliance with the handle attached to the back cover of the heater. The appliance should be no closer than 1000mm from the sides and 1000mm from above to all combustible surfaces, fabrics, flammable materials & people.

2. Insert two ‘D’ batteries into the battery box (FIG 1). Match the battery polarity as shown inside the battery box lid.

3. Attach the gas hose and gas regulator to the gas inlet (FIG 2). Tighten this connection with a spanner. Do not over tighten.
   

4. Connect the other end of the gas hose and gas regulator to the gas cylinder. Hand-tighten the connection.
   Note: Never place the gas cylinder directly beside or above the appliance.

5. Turn the gas cylinder on (open) in an anti-clockwise direction one full turn, and then check the connections for leaks with soapy water. DO NOT use a flame. If a leak is detected, turn the cylinder valve off (close) and re-tighten all connections and retest.

6. Once you determine that there are no leaks present with the gas valve open, turn the cylinder valve to the off (close) position.

7. Attach the shower head to the shower hose and connect that assembly to the water output (FIG 2). Make sure the switch is set to the ‘off’ position.

8. Connect a water hose with the hose adaptor to the water input (FIG 2), attach the other end of the hose to the water output on the supplied water pump. The flow direction is shown with an arrow.

9. Connect another water hose to the water pump input and place the open end of the hose into your water source.
   Note: Make sure the water pump is protected from any water. The pump is not waterproof.

10. Ensure the ignition switch located on the bottom of the unit is set to the ‘on’ position (FIG 3).
    

11. Connect the positive and negative wires of the water pump to the correct polarity on your car battery or battery box.
    Note: The water will fill the Gas Hot Water System, the system may try to ignite when it senses water flowing through it. The system will not ignite until we turn the gas on in the next step.
    IMPORTANT: It is important that when starting the appliance that the gas control knob is set to the minimum position, fully to the left, indicated by the thin dotted end of the curved line.
    IMPORTANT: It is important that when starting the appliance that the water regulator is set to the maximum position, fully to the left, indicated by the thick dotted end of the curved line.

12. Turn the gas cylinder on in an anticlockwise direction one full turn.

13. When you are ready to shower, simply press the switch on the shower head to the on position. Water will start to flow through the shower head within a few seconds.
    You should hear a series of clicks as the burners ignite. The burner flame can be seen through the viewing window located at the front of the appliance.

OPERATION

It is IMPORTANT that the following steps are followed to ensure that the appliance will start correctly.

1. Turn Season Control to SUMMER.
   

2. Turn GAS Control to LOW.

3. Set WATER to HIGH.

4. Check that the SHOWER HEAD flow control switch to ON.

5. Turn POWER SWITCH ON.
   

6. Water will start to flow from the shower head and the burner will ignite. Allow the Water
   Temperature to stabilize before making any adjustments.

ADJUSTING WATER TEMPERATURE

1. To increase Water Temperature turn GAS Control to HIGH and allow temperature to stabilise.

2. To increase WaterTemperature turn WATER to LOW and allow temperature to stabilise.

If ideal temperature is not achieved with the SUMMER setting the following steps can be followed:

1. Turn GAS Control to LOW.

2. Set WATER FLOW to HIGH.

3. Turn Control to WINTER.
   

4. To increase Water Temperature, turn GAS Control to HIGH and set WATER FLOW to LOW.
   Warning! Take care when testing the temperature of the water flowing from the shower head, as it may be hot enough to cause injury.
   The water flow can be stopped at any time by pressing the switch on the shower head to the off position. The burner will extinguish.
   To reignite the burner, press the switch on the shower head to the on position. The water will begin to flow, and the burner will ignite within 5 seconds.

WATER CYCLING INSTRUCTIONS

To achieve maximum water temperature at higher flow rates you can ‘cycle’ the water. To do
this, pump the water from a source reservoir (such as a bucket) through the heater and back into
the reservoir. You can cycle the water as many times as required to reach your desired
temperature, up to 50°C.

DRAINING THE HEATER WHEN STORING BELOW 0°C

When the ambient temperature is below freezing, it is essential to drain the water after using the heater. Failure to do so will void your warranty.

1. Ensure that the heater is disconnected from the gas supply.
2. Ensure that the heater is disconnected from the water supply.
3. Ensure that the shower hose is disconnected from the heater.
4. Turn the water flow knob to .
5. Loosen the screw in the water drain valve located at the bottom of the appliance, allowing the appliance to drain. Gently re-tighten the water drain screw when all water has drained from the heater.

STORING THE APPLIANCE

1. After use, turn the cylinder gas valve in a clockwise direction to the ‘off’ (close) position. The burner will continue to operate until all gas has been bled from the hose and regulator assembly.
2. Wait for the flame to go out, then press the switch on the shower head to the off position. The pump will automatically switch off.
3. Disconnect the water pump from the battery.
4. Disconnect the water hoses from the water pump and Gas Hot Water System and pack them away.
5. Disconnect the regulator and hose assembly from the appliance and gas cylinder and store away.
6. Disconnect the shower head and hose from the ‘water outlet’, hold the shower head approximately 1 metre from the ground and allow all water to drain out before rolling up and storing away.
