OPERATING PRECAUTIONS
Propane is heavier than air. If propane leaks from a connection or
fitting, it sinks to the floor, collecting there with the surrounding
air, forming a potentially explosive mixture. During set up check
all connections and fittings for leaks using soapy water. Never use
flame. Bubbles indicate a leak. Check that the connection is not
cross threaded and that it is tight. Perform another leak check. If
there is still a leak, remove the cylinder and contact Mr. Heater
direct for service or repair.
• Use for water heating only. Never alter in anyway or use with
any device or part not expressly approved by Mr. Heater.
• This appliance is designed to be used with a source water
temperature of 60°°F or below
•The maximum temperature rise from the appliances is 35À F
to the shower head and 42À F from the source water
temperature.
• For safety the appliance is designed to shut off the burner
when the water temperature from either of the outlets
reaches 122°F/50°C
• The average run time for the XCW20 from a fully charged
battery is 30 - 40 mins before it will require recharging
• During operation ensure that all air inlets and exhaust
(front,sides and back) are kept free from obstructions and
closure.
SAFETY FEATURES
This appliance is equipped with the following safety
features:
• Over Temperature Sensor – the appliance will not
allow the burner to remain in operation once the outlet
water temperature reaches 122ÀF/50°C.
• Water Flow Sensor – water must be flowing through
the system to allow the burner to ignite. In the case
that the water supply is restricted or ceases, the burner
will be extinguished and will not relight.
• Tilt Switch – in the event that the appliance is tilted past 30°
during operation the appliance will shut down until it is
located on a level surface.

5. Position the Output Temp Control Dial to the central position.
Depress the Pump button,the electronic ignition should be
heard igniting the burner. When the unit is ignited the Burner
icon on the control panel will illuminate and outlet water
temperature readout will increase. (FIG. 5)
6. Take care to measure the temperature of the water from the
shower head, the temperature can be adjusted by turning the
„ Outlet Temperature Control Dial „ until the desired level is
reached.
7. The water flow can be stopped at any time by sliding the
Switch to the „OFF‰ position (upwards). (FIG. 6) The burner
will extinguish and the pump will continue to operate for 5
minutes. To reignite the burner slide the Switch back to the
„OPEN‰ position (downwards), water will flow from shower
head and the burner will reignite within 5 to 10 seconds
IMPORTANT – Water remaining in the heat exchanger while the
flow is stopped may become hot. When the flow is resumed the
user must check the temperature output to ensure that it is
suitable and not too hot. Test water temperature before bathing
children or pets.
8. Once finished with the appliance slide the Switch to the
„OFF‰ position and depress the Pump button to stop the flow
of water to the appliance.
OPERATING FAUCET INSTRUCTIONS
1. Press the power button and once the unit is ON depress the
Shower Head / Faucet button until the Faucet LED„Outlet‰
indicator lights on the LED control panel. (FIG. 7)
2. Swing the faucet away from its storage position and locate
towards the side of the appliance and locate a basin or bucket
beneath and locate the water flow to the central position.
(FIG 8.)
3. Position the „ Outlet Temperature Control Dial „in the Max posi-
tion then press the „Pump‰ button, water will start to flow within a
few moments.
4. The electronic ignition should be heard igniting the burner,
when lit the „Burner‰ icon on the display will illuminate and
the outlet water temperature read out will increase. (FIG. 5)
5. The water temperature can be adjusted by moving the „Output‰
Temp Control Dial knob between „Min & Max‰ or at the „Flow‰
valve at the Faucet. Turning the flow dial counterclockwise will
reduce the flow and cause the water temp to increase. Turning
the flow dial clockwise will increase the flow and cause the water
to decrease.
6. The shower head hose can also be attached to the Faucet by con-
necting the quick connection from hose onto the Faucet outlet.
