Maintaining Your Product 12
Properly maintained, your water heater will provide years of dependable trouble-free service. It is
recommended that a periodic inspection of the burner, water filter and top exhaust should be
made by service personnel qualified in gas appliance repair.
It is suggested that a routine preventive maintenance program be established and followed by
the user.
Inspect the area around the water heater to ensure a safe operating environment. Keep water
heater area clear and free from combustible materials, gasoline, and other flammable vapors and
liquids. Ensure the unit has not been damaged. If damage or denting is present, contact a service
personnel to verify proper operation.
Check for any abnormal sounds during normal operation of the water heater.
All piping should be checked for gas and/or water leaks. Refer to page 4 of this manual for
instructions on leak testing.
The air intake and cold water supply filters should be cleaned monthly.
DO NOT operate the water heater if you feel something is wrong with the unit.
DO NOT allow children to operate or otherwise handle the unit.
DANGER: Before disconnecting the water supply, make certain no one will be exposed
to the danger of the hot water released by disconnecting. The water may be hot enough to
create a scald hazard. The water should be released into a suitable drain to prevent injury
or property damage.
DANGER: Hotter water increases the potential for hot water scalds.
DANGER: Failure to perform the recommended routine preventative maintenance can
harm the proper operation of this water heater, which can cause carbon monoxide dangers,
excessive hot water temperatures and other potentially hazardous conditions.

Troubleshooting Steps
13
Portable tankless water heater will not start- there are no audible clicks at startup:
a. The first thing to check is to ensure that the incoming water on the “right” side of the
portable tankless water heater. If the incoming and outgoing are reversed, the portable
tankless water heater will not work. The incoming is on the far right and the outgoing is in
the middle.
b. Check to make sure you have fresh batteries and they are installed in the correct position.
c. The top reason that the portable tankless water heater does not ignite is that there is not
enough water pressure. You need a minimum of 3.6 PSI, sustained. Municipal water should
supply enough water pressure.
ADJUSTMENT:
d. It is possible that some debris or epoxy might have entered the water inlet pipe. Check to
see if the filter screen on the water inlet is clear of debris. You can also reverse the hookup by
taking your water source and hooking it up to the water outlet side and back flushing the
system.
e. Propane gas cylinders sometimes are contaminated with air, especially new cylinders upon
their first filling. Cycle the portable tankless water heater turning off and on your output flow
or similar.
Should a portable tankless water heater fail to light or stat lit after 10 cycles, please contact
us via email at [email protected]
Portable tankless water heater starts, then shuts off:
a. The portable tankless water heater requires a minimum if about 0.44 gallons per minute
(1.5 liters ) and a minimum of about 3.6 PSI / 0.25 bar.
Note: Water pressure is at the lower end of operating parameters. You will need a sustained
water pressure of approximately 35-65 PSI / 2.4-4.5 bar for adequate use if you are using a
12/18/120 volt pump.
b. Out of, or low on gas. Propane gas sometimes are contaminated with air, especially new
tanks upon their first filling. Cycle the portable tankless water heater on and off by using the
shower head switch several times to purge the air from the gas. If this doesn’t clear the air
then the tank must be purged.
c. One of the ignition sensors is bent and/ or too close to the burner. Look to ensure that the
ignition pins and the heat sensor are completely vertical and they do a 90 degree to the back
of the box. If they are not straight (i.e. a 45 degree angle) then you can straighten them with
pliers.

14
d. The thermocouple is either too high or too low to complete the circuit. Check to ensure that
the thermocouple is flush with the hold in the heat exchanger.
e. The gas sensor wire (looks like a black ground wire on the gas regulator) flange might have
come loose or is no longer connected.
f. There is a faulty heat sensor. This is usually diagnosed by taking the front case off of the
portable tankless water heater and let it run. If it continues to operate, then one of the sensors
and/or the wire harness needs to be replaced. This may also be caused by insufficient clearance
on the back of the portable tankless water heater where the majority of air intake is.
g. The valve on the propane tank should be all the way “Open”.
h. Fresh batteries are required for ignition spark. Make sure batteries are aligned in the proper
polarity (+/-).
The water does not get hot enough:
a. You are operating the portable tankless water heater above 6,000 feet / 2,000 meters. We only
recommend using it below elevations of 6,000 feet.
b. Look into the viewer panes (middle horizontal windows on the front cover) to see if there is a
blue flame. If the flame is yellow there could be a cracked gas regulator. Do Not Attempt to use
the portable tankless water heater.
Water is flowing, but there is no hot water coming out:
a. Ensure that you have the incoming water supply and the outgoing water supply hooked up
properly. Your water supply should be attached to your incoming connection (located on the far
right) and the shower head should be attached to the outgoing water (located as the middle
connection).
b. Ensure that you have adequate water pressure of at least 3.6 PSI / 0.25 bar, sustained.
c. Ensure that you have adequate gas in your propane bottle and that the LP regulator is thread-
ed all of the way on to the portable tankless water heater.
d. Fresh batteries are required for ignition spark. Make sure batteries are aligned in the proper
polarity (+/-).
The portable tankless water heater does nothing:
a. Ensure that you have your water source hooked up to the water inlet side (far right connec-
tion) and the shower handle is hooked up on the water outlet side (middle connection).
b. Ensure that you have an adequate supply of propane.
c. Ensure that you have fresh batteries.
