• 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. Finda 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.
   Locate a solid, non-combustible vertical surface where you can securely install the shower head holder using the provided mounting hardware.
   Ensure that the distance from the water outlet to the installation site does not exceed the length of the shower hose.

2. Insert two ‘D’ batteries into the battery box (FIG 1). Make sure the battery polarity is correct.

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. Divide the water pipe into two segments, taking into account the distance to the water source. One segment will run from the water source to the pump, while the other will connect the pump to the gas water heater.

9. Install the water inlet filter on the segment running from the water source to the pump. And attach the female quick connectors to the other three ends of the water pipes. Place male quick connectors on the water pump (2 pieces) and the water inlet of the gas water heater (1 piece). Now, proceed to connect the male and female quick connectors, forming three sets in total. Submerge the water pipe with the water inlet filter into the water source.
   Note: Make sure the water pump is protected from any water. The pump is not waterproof (FIG 3).

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

11. Connect the water pump to the cable with cig socket, and then to the cable with alligator clips to power it using your battery. Alternatively, you can simply connect the pump to the cable with the cig socket to power it from your vehicle.
    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.

   lf 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 45+3°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.

Check for sufficient water pressure. The unit must have a minimum of 0.03 MPa of sustained water pressure to activate the burners.
There may be debris in the water inlet. Check that the water inlet filter screen is clean. To flush the system, you can reverse the flow by taking the water inlet pipe and connecting it to the water outlet.
The gas line may need purging. Turn gas to maximum and burners to High on the unit and turn the water on/off a few times.
Check that the shower flow water regulator is in the open position.
Check that water is flowing through correctly. Make sure “Water In” and ‘Water Our are in the correct position.
Make sure the On/Off switch is turned on. do this by having the red dot pushed in.
If the unit fails to ignite when LED display lights and ignition is clicking:
1. Disconnect all gas attachments from the unit and gas bottle.
2. Re-connect your gas line to the unit including all tapes (do not turn the gas on).
3. Turn your water supply on.
Once the unit starts to click, turn you r gas bottle on slowly and watch for ignition through the window.
Water flows through the unit, but is not hot| New batteries may be required for the ignition switch. Check the cap of the battery case for instructions on how they should be installed. In high humidity conditions it may be necessary to clean and dry the battery box prior to operation.
Check for sufficient water pressure. The unit must have a minimum of 0.03 MPa of sustained water pressure to activate the burners.
Ensure that the liquid propane regulator is threaded all the way to the unit and that you have an adequate amount of gas in your propane bottle.
Check that water is flowing through correctly. Make sure “Water In” and ‘Water Our are in the correct position.
Try the unit on mains water if possible, if this works, there is an issue with the pump.
Water is not hot enough| Adjust the gas regulator and water regulator to meet your desired temperature. To increase temperature, turn the
gas regulator control from minimum to maximum and turn the water regulator control from maximum to minimum.
Turn the burner control knob, in the centre of the unit, to the Winter setting. This will activate more burners.
Check source water temperature. If the source water temperature is too cold then you can ‘cycle’ the water (see WATER CYCLING INSTRUCTIONS on page 11).
Check the flame in the ‘viewing window’. If you see a yellow flame it could mean a breakdown in the gas regulator. Please call us directly if this happens: do not attempt to use the heater.
Check your Gas Cylinder to ensure it is not empty. If using a new cylinder, turn gas to maximum and burners to High on the unit and turn the water on/off a few times to purge the air from the gas lines.
