The Purpose and Benefits the L-10
The EccoTemp L-10 is a liquid propane fired water heater capable
of delivering 2 to 2.65 gallons of hot water almost anywhere. The
unit has standard 1/2“NPT pipe fittings and an adapter for using a
standard garden hose for inlet water supply.
The L-10 is not a toy. People around the world use similar units to
heat the water in their homes, safely, and reliably.
Gas is supplied from a standard 20 pound propane cylinder (not
included) such as used with outdoor grills. A regulator with hose is
furnished with the heater.
The unit includes a stainless steel rain cap that is to help venting
of the flue gases as well as protect it for outdoor usage.
Ignition is automatic and powered by 2 “D” cell batteries (not
included). Burners come on when water flows, and off when the
water is shut off. No pilot light!

NATURAL GAS AND LIQUIEFIED PRETROLEUM MODELS
Both LP and natural gas have an odorant added to aid in the
detecting a gas leak. Some people may not physically be able to
smell or recognize this odorant. If you are unsure or unfamiliar
with the smell of LP or NG, ask the gas supplier. Other conditions
such as “odorant fade”, which causes the odorant to diminish in
intensity, can also hide or camouflage a gas leak.
Water heaters utilizing LP gas are different from natural gas
models. A natural gas water heater will not function safely on LP
gas and vice versa
No attempt should ever be made to convert the water heater
from NG to LP gas. To avoid possible equipment damage,
personal injury, or fire, do not connect the water heater to a fuel
type not in accordance with the data plate.
LP gas must be used with great caution. It is heavier than air
and will collect first in lower areas making it hard to detect at
nose level.
Before attempting to light the water heater, make sure to look
and smell for gas leaks. Use a soapy solution to check all gas
fittings and connections. Bubbling at a connection indicates a
leak that must be corrected. When smelling to detect a gas leak,
be sure to sniff near the floor also.
Gas detectors are recommended in LP and NG applications and
their installation should be in accordance with the detector
manufacturer’s recommendations and/or local laws, rules,
regulations or customs.
DANGER!

ADDITIONAL WARNINGS
1. Do not leave unattended
2. The exhaust gas and top of the
unit is HOT! Do not place hands
or any foreign object near the top
of the heater.
3. Do not use in high wind
conditions
4. If the smell of gas is detected,
turn off the gas valve at the tank
immediately! Do not use flame for
leak detection.
5. Use only Liquid Propane
6. Use only outdoors
7. Do not over tighten the gas
regulator connection to the unit
with a wrench. This may cause a
crack in the gas regulator.

The Purpose and Benefits the L10
The EccoTemp L-10 is a liquid propane fired water heater capable
of delivering 2 to 2.65 gallons (up to 10 liters) of hot water almost
anywhere. The unit has standard 1/2“NPT (BSP for European
models) pipe fittings and an adapter for using a standard garden
hose for inlet water supply (North American models).
The L10 is not a toy. People around the world use similar units to
heat the water in their homes, safely, and reliably.
Gas is supplied from a standard propane cylinder (not included)
such as used with outdoor grills. A regulator with hose is furnished
with the heater.
You may also plumb it in to existing water lines and using a low
pressure LP gas regulator. Check local codes for proper
installation.
The unit includes a stainless steel rain cap that is to help venting
of the flue gases as well as protect it for outdoor usage.
Ignition is automatic and powered by 2 “D” cell batteries (not
included). Burners come on when water flows, and off when the

Construction and Name of Parts for the
L10 Flue Duct System

10
Getting Started
1. Check box for damage. Damages caused in shipment
must be reported immediately.
2. Make sure you have all the parts:
a. Water heater
b. LP gas regulator and hose
c. Rain cap
d. ½” NPT to garden hose adapter (North American
models)
e. Hardware pack
3. Install the rain cap to the top of the flue vent. The rain
cap should fit securely. It is recommended that a beaded
layer of high temperature sealant is used around the
perimeter of the seal between the rain cap and the flue
vent.
4. If using a standard garden hose, attach the ½” NPT to
garden hose adapter to the fitting marked with the blue
arrow (far right connection) on North American models
only. For European models, attached your water source
hose to the far right connection. Use “Teflon” tape or
other approved sealing method on the threads for a
secure, water tight fit. Check to make sure the screen
inside the water inlet is in place and clean. Then attach
your water input/garden hose.
5. Install gas supply line and regulator to the unit. DO NOT
OVER TIGHTEN. OVER TIGHTING MAY CRACK THE
GAS REGULATOR CAUSING A GAS LEAK! Check for

11
any gas smell before ignition! Make sure it is screwed all
the way on. For European models, ensure that the black
rubber washer is securely in the gas input connection.
6. Attach your water output apparatus to the fitting marked
“Water Outlet”. Do not over tighten! If installing in an
existing water system, connect the hot water line directly
to the ½” NPT/BSP fitting.
7. Install two “D” cell batteries in the compartment on the
bottom left of the heater. Check that batteries are facing
the correct direction.
8. Use the top tab on the unit to suspend from a screw
adequate to holding 30 pounds/13 KG. Place at a
comfortable height without putting stress on the gas
hose. If the unit is to be permanently mounted, use
screws to attach the bottom tab firmly.
9. Attach gas regulator with hose to the LP tank. Use hand
pressure only on the plastic connector. LEAVE GAS
TANK VALVE IN THE “OFF” POSITION”.

12
Before going to the USE section:
Check around area for flammables, especially
gasoline or other vapors which may ignite. The
exhaust and top of the unit will get HOT! Make sure
there are no foreign objects around the unit or have
fallen into the top.
Use and Starting
1. Turn on incoming water supply. Ensure that you have
adequate water pressure of between 20-80 PSI /1.38-
5.5 bar.
2. Turn your water output device to its “off” position.
3. Turn the gas valve on the cylinder all the way open.
4. IF THE SMELL OF GAS IS DETECTED, TURN OFF THE
GAS VALVE IMMEDIATELY!!!!
5. Set the water regulator knob on the face of the unit to
its highest setting.
6. Set the gas regulator knob on the face of the unit to
its minimum setting.
7. Turn on your water output device to the “on” position
and adjust to the desired water flow.
8. There will be a series of audible clicks and the burner
will ignite. (Should the burner not ignite after 5
seconds, shut off and go to the “Trouble Shooting”
section.

13
9. Upon completion of use or storage, open the drain
valve (ribbed cylindrical stem next to the water input
valve) to ensure draining of water.
10. Turn off your gas supply.
11. WARNING: If the outside temperature is around or
below freezing (32 degrees F, 0 degrees C), ensure
that the drain valve is opened and water drained from
the unit after each use to avoid internal damage to the
water regulator. You will also need to unhook the
outgoing water line to ensure that any water in the
heat exchanger is drained. Failure to properly drain
your unit will cause water damage which may or may
not be reparable. Please check the warranty
information found on our website at
www.eccotemp.com/freeze for more information on
freezing issues.

14
ADJUSTMENT
The temperature of the outgoing water is dependent on the
temperature of the incoming water balanced with the amount of
heat applied. Use extreme caution in setting the outlet water
temperature.
1. With the water regulator set to high, and the gas
regulator set to low, feel the outgoing water. This is
the lowest setting available.
2. To initially raise the outgoing temperature, slowly turn
the gas valve towards maximum. Adjust slowly and
check the temperature often. There will be a slight
delay between increasing the gas supply and the
increase in water temperature.
3. Should the outlet water temperature need to be
higher, slowly reduce the water flow regulator until
desired temperature is reached.
WARNING:
THE UNIT IS CAPABLE OF PRODUCING
SCALDING WATER TEMPERATURES!

DO NOT RETURN TO STORE:
Call Eccotemp or one of its International
Distributors directly found on page 1 if you
encounter a problem!
TROUBLE SHOOTING
Unit 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 unit. If the incoming and outgoing are
reversed, the unit 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. Number one reason that the unit does not ignite is that there is
not enough water pressure. You need a minimum of 20 PSI/1.38
bar, sustained. Municipal water should supply enough water
pressure. Most 12/18/120/240 pumps well as long as they are
capable of delivering pressure of 30 PSI / 2 bar or greater.
ADJUSTMENT: Looking up at the bottom of the unit, you will see
two “slits” in the case where the front and back come together.
Locate the water regulator where you will see two Philip head
screws. Take the screw that is furthest on the right (larger screw)
in about a ¼ or ½ turn. This will enable the unit to operate on a
lower water pressure by restricting flow.

17
NOTE: Before attempting to remove the cover, call technical
support found on page 1
e. A wire has become disconnected inside the unit during
shipping. Make sure the gas is OFF. The front cover is held by six
screws, four on top, two on bottom. The knobs pull off. All the
wiring is done with push together plastic connectors. They are all
visible without further dismantling of the unit. It should be obvious
when a wire has become disconnected.
f. It is possible that some debris or epoxy might have entered the
water regulator. 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.
g. 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.
Should a unit fail to light or stay lit after 10 cycles, Call
technical support found on page 1
Units starts, then shuts off:
a. The unit requires a minimum of about 0.5 gallons per minute (2
liters) and a minimum of about 20 PSI / 1.38 bar* Note, water
pressure is at the lower end of operating parameters. You will
need a sustained water pressure of approximately 40-60 PSI / 2.7-
4.1 bar for adequate use if you are using a 12/18/120/240 volt
pump. See ADJUSTMENT in previous section above.
b. High wind
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.

18
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 or oxygen 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 6,000 feet / 1820 meters.
While it has been field tested up to 7,200 feet / 2195 meters, we
only recommend using it below elevations of 6,000 feet / 1820
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.

19
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 (+/-)
If you are still having troubles or are on a modified water system,
please call technical support at found on page 1
The unit does nothing:
a. Ensure that you have your water source hooked up to the water
inlet side (far right connection) and the shower handle is hooked
up on the water outlet side (far right connection)
b. Ensure that you have an adequate supply of propane
c. Ensure that you have fresh batteries
If you are still having troubles or are on a modified water system,
please call technical support at found on page 1
