c. Out of, or low on gas. Propane gas cylinders sometimes are contaminated with air, especially
new tanks upon their first filling. Cycle the unit on and off by using the shower head switch
several times (5) to purge the air from the gas.
If this doesn’t clear the air then the tank must be purged.
d. 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.
e. The thermocouple is either too high or too low to complete the circuit. Check to ensure that the
thermocouple is flush with the hole in the heat exchanger.
f. The gas sensor wire (looks like a black ground wire on the gas regulator) flange might have
come loose or is no longer connected.
g. There is a faulty heat sensor. This is usually diagnosed by taking the front case off of the unit
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 unit where the
majority of air intake is.
h. The valve on the propane tank should be all the way “Open”.
i. 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 unit above 3,900 feet / 1,000 meters. We only recommend using it below
elevations of 3,900 feet / 1,000 meters.
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 unit and call Eccotemp directly.
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 center
connection)
b. Ensure that you have adequate water pressure of at least 20 PSI / 1.38 bar, sustained.
c. Ensure that you have adequate gas in your propane bottle and that the LP regulator is threaded
all of the way on to the unit.
d. Fresh batteries are required for ignition spark. Make sure batteries are aligned in the proper
polarity (+/-)
