temperature is around or  below freezing  (32 degrees F, 0 degrees C).  Unhook the 
outgoing  water  line  to  ensure  that  any  water  in  the  heat  exchanger  cause  is 
drained. The lack of proper drainage in your unit may cause damage to the water 
heaterthat will not be repairable. See our warranty policy.

The  temperature  of  the  incoming  water  with  the  amount  of  heat  applied  are 
influential in the temperature of the outgoing water. 

1. 

Set the gas regulator to low, and the water regulator to high, feel the outgoing 

water. This is the lowest setting available.

2.

 To raise the outgoing temperature, turn the gas valve towards maximum. There 

will be a slight delay between increasing the gas supply and the increase in water

3.

 If you wish to use water without it being heated turn the ON/OFF switch at the 

bottom of the unit to “OFF” (“0”). This will disconnect the gas flow and igniters.

 

temperature. If you want the highest setting available then turn water regulator all 
the way to the maximum. Adjust slowly and check the temperature often.

The unit will produce temperatures capable of harming the skin! Make sure 
that you test the water before taking a shower!

The units does not start at all

1. 

Make sure you have new batteries installed in the correct position. Check the cap 

of the battery case for instructions on how they should be installed.

2.

 Usually, the main reason most units does not ignite is that there is not enough 

water pressure.  The unit must have a have a minimum of 5 PSI of sustained water 
pressure to turn on.

3.

 Verify that the water hoses are connected properly, if they are not the unit will not 

work. Check that the incoming is on the far right and the outgoing is in the middle.

4.

 The "On/Off" switch should be with the “—“ sign pushed down.

ADJUSTMENT: 

On the bottom of the unit, you will see 2 oval holes in the case.   

The furthest hole on the right looks up at the water regulator where you will see two 
Philip head screws.  Furthest on the right the is a screw that you must turn about a 
¼ or ½.  The unit will be able to operate on a lower water pressure by restricting the 
flow. 

5. 

During shipping if a wire disconnected, make sure that the gas valve and the 

switch is shut off. The front cover is held by four screws, two at the top and two at the 
bottom.  The  knobs  pull  off.  All  the  wiring  is  done  with  push  together  plastic 
connectors. When a further dismantling of the unit they are all visible. 

6. 

There is a possibility that some epoxy or debris might have entered the water 

regulator.   Check that the water inlet filter screen is clear of debris. To flush the   
system you can reverse the hookup by taking the water source and hooking it up to 
the water outlet side and back.

If the gas cylinder is contaminated by air, cycle the unit on and off several times to 
purge the air from the gas.
