OPERATION
This instantaneous and continuous gas water heater efficiently supplies domestic or
commercial hot water. It operates on the principle of heating water only on an “on
demand “ basis. Once a hot water faucet is opened, cold water flows through the coils
of the heat exchanger. This same flow opens the gas valve, and the burner is ignited by
the pilot flame, battery spark igniter or the hydro-generator, depending on the model
selected. The coils and body of the heat exchanger absorb the heat generated by the
main burner and transfer the heat to the water. When the hot water faucet is shut off,
the gas valve automatically closes and the burner turns off.
To turn on your water heater, simply open any hot water faucet. Each time you shut off
your hot water faucet, you also shut off the water heater.
PREPARING THE WATER HEATER FOR OPERATION
For your safety, read the instructions thoroughly before operating.
WARNING: If the information in these instructions is not followed exactly, a fire or
explosion may result causing property damage, personal injury or death.
a) Models without a pilot light are equipped with an electronic ignition device, which
automatically lights the burner. Do not try to light the burner on these models
(having an “X” or “H” in their part number) by hand.
b) Before operating, check for any gas vapor accumulation in the areas around the
heater. Pay special attention to areas near the floor as gas vapors are often
heavier than air, and may accumulate near the floor.
c) Do not use this appliance if any part has been under water. Immediately call a
qualified service technician to inspect the heater and to replace any part that may
have been damaged by being under water.
WARNING: IF YOU SMELL GAS:

INITIAL OPERATION
Models: TE80X, TE80H, TE125X, TE125H
1. STOP! Do not operate this water heater without reading the safety information first.
2. If you do not have the TE80X or TE125X battery spark electronic models, proceed to
point 3. The TE80X and TE125X (NG or LP) models are equipped with the D-Cell

battery sparker. Before operating this unit, two D-Cell batteries are to be installed in
the battery compartment.
To accomplish this, first remove the front shield by holding it with both hands at the
bottom edges and pulling it gently toward you. When both prongs come out of the
holes in the front shield, lift the shield about 4 inches until both screws come out of
the heater’s back shield. Take care when doing this so as not to damage the
battery compartment. Now open the battery compartment by depressing the pushbutton as illustrated in Fig.1.
Install two D-Cell batteries in the battery
compartment, aligned as indicated. Close the lid of the battery compartment.
Replacing the front shield can only be done when the temperature selection knob
and gas control knob are removed.
Fig. 1 Opening the battery compartment
3. Open the natural gas line valve running to the heater. For liquid propane models,
open the valve at the gas cylinder or tank.
4. Rotate the gas control knob from position “0” to one out of four gas flow positions

5. Set the desired water temperature and the water flow rate using the temperature
selection knob.
6. After opening the hot water faucet you will hear an electronic clicking sound on
models equipped with an electronic sparker (Models with an “X” or “H” in the part
number.) Standing pilot light models are relatively quiet. Shortly the gas will light
up on the ignition burner, and momentarily later on the main burner. The heater
is now operating and supplying hot water.
If the ignition burner does not light the first time (the gas flow is automatically stopped
after 50 seconds) turn off the how water facet and allow a few seconds for this to reset.
Turn on the water faucet again and repeat the process allowing the ignition burner to
light. Repeat, as many times as necessary, until the ignition burner lights and the then
the main burner on the heater comes on. Be sure the gas line has been purged of air as
describe on page 11 of these instructions
Opening the hot water faucet creates water flow which in turn automatically ignites
the ignition burner which then ignites the gas for the main burner. Water flows
through the heat exchanger and hot pipes and finally out of the faucet.
7. When closing the hot water faucet, the inflow of gas to both the ignition burner and
the main burner is cut off, and the water heater will shut off.
INITIAL OPERATION
Models: TE80P, TE125P
1. STOP! Do not operate this water heater without reading the safety information first.
2. Open the natural gas line valve running to the heater. For liquid propane models,
open the valve at the gas cylinder or tank.
3. Turn the gas control knob left (about 20º), press home and turn left till you hear a click
of piezoelectric lighter (i.e. about 75º from the previous position), with this, a spark
appears which will light up the gas on the pilot burner. Hold the so pressed knob for
about 10 seconds. In case of not lighting up the gas, repeat these steps.

SETTING WATER TEMPERATURE AND WATER FLOW
ThermElite instantaneous gas water heaters are equipped with a highly-engineered
combination gas and water valve which ensures proportional regulation enabling the
water heater to produce a stable water temperature at the hot water faucet. This
gas/water valve, controlled by the temperature control knob, regulates the amount of
water flowing to the heater. If the temperature selection knob (Fig.2) is turned to its
extreme right position, the water heater obtains the least flow of water, for example, 2.1
gallons per minute for the TE125 models. The highest temperature rise is obtained by
setting the gas flow selector knob to its highest position while setting the temperature
(water flow) knob to its lowest position. This “restricts” the flow of water in the heat
exchanger for a longer period of time for additional heating. If the temperature selection
knob (gas/water flow) is turned to the extreme left position, the Model 125 water heaters
obtain their greatest flow of water, 4.2 gallons per minute with the least rise in
temperature. Check the performance specifications for your specific water heater on the
box or at the back of this manual.
Setting the temperature selection knob to the various incremental positions causes the
temperature rise to change inversely proportionately to the amount of water flow. The
flow rate, for example on the TE125 models, can be adjusted between 2.1 and 4.2
gallons with a temperature rise of between 45 and 90 degrees Fahrenheit. The
temperature of water (in any set position of the temperature selection knob) can also be
controlled by means of adjusting the gas control knob.
•
We recommend setting the temperature selection knob between the low and high
positions and the gas control knob between position 3 and 4.
•
If the gas control knob is set to the extreme left position and the temperature
selection knob is set to the extreme right, there is a risk of being scalded.
•
Energy efficiency is the greatest at lower tolerable temperatures.

TURNING THE WATER HEATER OFF
If the water heater will not be used for extended periods of time, it should be shut off and
drained for safety reasons and to prevent possible damage.
To shut the water heater off, turn the gas control knob to the position “0“ and close the
natural gas valve on the gas supply line running to the water heater or the valve on the
cylinder or tank if the water heater uses liquefied propane gas.
Drain the heater entirely if freezing temperatures are anticipated in the area where the
heater is installed. To accomplish this, shut off the main valve controlling the inflow of
cold water to the heater. Open the hot water faucets in the building to drain any
standing water in the pipes. Finally, loosen the nut on the cold water supply line and
capture any draining water in a pan or bucket, around 2-3 cups of water.
INSTALLATION
This section is for the installer. The installer is responsible for the correct installation of your
instantaneous gas water heater.
FOR YOUR SAFETY: Only a certified and trained service technician or qualified plumber
should service or install your product. If installed by the homeowner, a qualified plumber or
certified technician should inspect the installation prior to operation.
Please keep this instruction manual in a safe place for further reference.
The installation of this appliance must conform to local codes, or in the absence of local
codes, the National Fuel Gas Code ANSI Z 223.I / NFPA 54
LOCATING THE TANKLESS WATER HEATER
Carefully select the location of your new water heater. As with all gas appliances, for
your safety and for proper heater operation, you must ensure that there is an abundant
supply of combustible air and the proper installation of the venting.
1. Place your heater as close to a vent or a chimney as possible and in a place not
exposed to possible freezing conditions.
2. Keep the water heater area free and clear of combustible materials, gasoline and
other flammable liquids and vapors. If installed in a garage, mount the water
heater a minimum of 3-feet above the floor where automobile gasoline fumes
might collect.
3. Do not install the water heater directly above a carpeted floor or above any
material which could possibly burn.
4. This appliance should be located where accidental water leakage will not damage
the flooring below.
5. The location where you install the heater must have adequate ventilation.

COMBUSTION AIR SUPPLY
Your tankless gas water heater must be installed in a location where the proper amount
of combustible air will be available to it at all times. Observe the following guidelines
concerning combustion air.
If the water heater is located in a confined space, there must be permanent openings
supplying air to the unit. If the openings will bring air directly from the outdoors, two
openings are required, and they should be sized to give a minimum free area of one
square inch for every 4,000 BTU/H of the maximum input rating of the unit. If the
openings will bring air from an indoor area, they should be sized to give a minimum free
area of one square inch for every 10,000 BTU/H of the maximum input rating of the unit.
One of these openings should be within 12’’ of the ceiling, and the other should be within
12’’ of the floor.
EXHAUST VENTING
The heater should be installed as close as possible to a chimney or vent, and in a place
not exposed to freezing, rain or other inclimate weather conditions.

GAS SUPPLY PIPING
Before connecting the gas supply, check the rating plate on the side of the front cover to
be sure that the heater is designed for the same gas to which it will be connected. You
cannot connect a water heater that has been plumbed for natural gas (NG) to a liquefied
propane (LP) gas source or vise versa. Fuel conversion kits are available but, by law,
may only be installed by a licensed, certified plumber.
In the United States: The installation must conform with local codes or in the absence of
local codes, to the National Fuel Gas Code ANSI Z223.1/NFPA54. It is recommended
that the gas connection to the heater be copper or steel gas supply piping.
Always purge the gas line of any debris before connecting it to the water heater.
Bleed Gas Line– Before starting the heater, the first time, be sure to bleed the Gas Line
as it enters the heater (see figures 11, 12 & 13 at Part number 15). Do this by loosening
the gas line where it is attached to the heater (at the end of the gas flex connection if a
flex is used to connect the gas line). Let a small amount of gas escape ( when you first
smell the gas coming out of the loosened gas line) to bleed the line and then securely
reattach the nut on the line to prevent any gas leakage
WARNING: The tankless gas water heater must be isolated from the gas supply piping
system by closing the manual shutoff valve during any pressure testing of the gas supply
piping system at test pressures equal to or more than 0.5 psi. The appliance must be
isolated from the gas piping system by closing its individual manual shut off valve during
any pressure testing of the gas supply piping system at test pressures equal to or less
than ½ psi (3.5 kpa). When your connections are made, check for gas leaks at all
joints. Apply some soapy water to all gas fittings and gas valves. Soap bubbles are a
sign of a leak. Never test for gas leaks using a match or flame.
Always install an in-line manual shut-off valve on the gas supply line in case of an
emergency, or if service or maintenance is necessary.
A gas
fuel filter should
be installed between the manual shut-off valve and the heater

GAS PRESSURE REGULATOR
NOTE: The tankless water heaters TE125X, TE125H, TE80X and TE80H are supplied
with a gas pressure regulator that must be installed on the heater before attaching the
gas supply line. (See Fig.8)
Failure to install the gas regulator as illustrated will violate the CSA certification of the
unit. The regulator supplied with the heater is pre-set to the correct pressure for the gas
shown on the rating plate to the correct pressure.
The pressure regulator provided with the heater is adjusted to deliver the proper gas (LP
or NG) pressure (as indicated on the rating plate).
Fig.8 Gas Pressure Regulator
NOTE: Models TE80P and TE125P are supplied with a gas pressure regulator that is
built in the gas/water unit.
Note: An embossed arrow on the rear of the Gas Pressure Regulator indicates the flow
direction of the fuel. Always install the regulator with the arrow pointing in the direction
of the heater inlet.
WATER CONNECTIONS
Install a manual in-line water control valve on the inlet water line. Although water piping
throughout your structure may be other than copper, we recommend that copper piping
be used for at least three feet before and after the water heater. Be sure to use a
dielectric union to prevent electrolysis. If the water heater is installed in a closed water
system, means should be provided to control thermal expansion such the installation of
a water expansion tank. Contact the water supplier, a certified plumber or the local
plumbing inspector on how to handle this situation.
Be sure to remove the plastic pipe stops (used for shipping purposes only) at the water
connections before connecting the water pipes to the heater. Connect the cold water
pipe to the right water-in connection, as you face the heater. Connect the hot water pipe
to the left water-out connection, as you face the heater.
11
ISU-217:2004

PRESSURE RELIEF VALVE
NOTE: An approved pressure relief valve must be installed in conjunction with
this unit. The pressure relief valve must be installed on the hot water line out of
the unit with no check valves or control valves between the water heater and the
pressure relief valve. Do not plug the pressure relief valve. The pressure relief
valve should be manually actuated once a year to check for proper operation.
Caution:
When operating the relief valve make sure that the water heater is not operating and the
burner is not lit. Stay as far away from the valve as possible in order to reduce the
possibility of being burned from the release of steam or hot water from the release valve.
There is no necessity to operate the valve unless the system is be purges or the heater
is being removed for replacement or repair.
WARNING:
If a relief valve discharges periodically, this may be due to thermal expansion in a closed
water supply system. Contact the water supplier or local plumbing inspector on how to
correct this situation. Do not plug the relief valve.
MOUNTING THE TANKLESS WATER HEATER ON THE WALL
ThermElite tankless hot water heaters are designed and certified for wall mounting with
no special wall preparation requirements. Select the location for the heater as desired,
following all applicable local codes. Adhere to all indoor clearances that apply to the
installation. Do not install this appliance on a carpeted wall or above any floor covering
which is combustible, such as carpeting or area rugs. The water heater must be
securely attached to a load-bearing wall. Secure the two hooks provided with the heater
to a wall surface. Hollow wall anchors may be used but it is recommended to use
wooden cross pieces secured to the wall studs. Position the cross pieces at the top and
bottom of the water heater. This will keep the water heater level while giving a more
secure fastening. Place the heater on hooks. See Fig.9 for required mounting
clearances to combustible and non-combustible walls.
WARNING:
If a water heater is installed in a closed water supply system, such as one having a
backflow preventor in the cold water supply line, means shall be provided to control
thermal expansion. Contact the water supplier or local plumbing inspector on how to
control this situation.

ADAPTING THE WATER HEATER TO DIFFERENT GAS TYPES (CONVERSION KIT
INSTRUCTIONS)
WARNING: This conversion kit shall be installed by a qualified service agency
in accordance with the manufacturers instructions and all applicable codes and
requirements of the authority having jurisdiction. The information in these
instructions must be followed to minimize the risk of fire or explosion or to
prevent property damage, personal injury or death. The qualified service agency
is responsible for the proper installation of this kit. The installation is not proper
and complete until the operation of the converted appliance is checked as
specified in the manufacturer’s instructions supplied with the kit.
A qualified service agency is any individual, firm, corporation or company which either in
person or through a representative is engaged in and is responsible for the connection,
utilization, repair or servicing of gas utilization equipment or accessories; who is
experienced in such work, familiar with all precautions required, and has complied with
all the requirements of the authority having jurisdiction.
IN CANADA THE CONVERSION SHALL BE CARRIED OUT IN ACCORDANCE WITH THE
REQUIREMENTS OF THE PROVINCIAL AUTHORITIES HAVING JURISDICTION AND IN
ACCORDANCE WITH THE REQUIREMENTS OF THE CAN-B149.1, NATURAL GAS AND
PROPANE INSTALLATION CODE.
The heater delivered by the manufacturer is designed for the gas shown on the rating
plate (Natural Gas or Propane). Check the rating plate on the side of the front cover to
be sure that the heater is designed for the specific gas to which it will be connected. If
gas conversion is required, determine to what type of gas the heater must be converted.
Turn off the gas supply before converting the appliance and leak test the converted
water heater prior to placing it into operation. To leak test all joints and replaced parts
apply some soapy water to the replaced joints and parts. Look for soap bubbles which
are a sign of a leak. Never test for gas leaks using a match or flame. A standard gas
detector can also be used to test for leaks instead of using soapy water. The manifold
pressure after the conversion shall be as outlined in the gas pressure table in the
installation instructions. Instructions on how to measure and adjust the manifold
pressure can be found in the Making Adjustments Section of the installation instructions
manual.
Please follow the minimum and maximum inlet gas pressure as outlined in the gas
pressure table in the installation instructions. To check the inlet pressure the qualified
service agency doing the conversion shall check the inlet gas pressure in the inlet gas
line after it exits the gas pressure regulator just before it enters the heater. The qualified
service agency shall use whatever gas pressure measuring instrument they commonly
use to test gas pressure.
25
ISU-217:2004
część angielska
After converting the water heater, please verify the input rate. The required input rate for
the Natural gas Model is 115,000 BTU/H and for the propane model is 100,000 BTU/H.
The burner flame size and shape can be seen in the instructions manual in the
schematic diagrams. The pilot flame is automatically adjusted when the ignition burner
nozzle is replaced by following the instructions under REPLACEMENT OF THE
NOZZLE IN THE IGNITION BURNER found on page 30 of these instructions.
The input rate is based on sea level operation (i.e., up to 2,000 ft elevation). For the
USA, for operation at elevations above 2,000 ft, the input rating shall be reduced at the
rate of 4% for each 1,000 feet above sea level. The models TE125X, TE125H are not
approved for high altitude in Canada.
Make sure that the following checklist of parts from the conversion kit has been installed.
1. Gas cone replacement part (1 piece) was changed and installed.

PROTECTION SYSTEMS
•
ThermElite tankless gas water heaters feature a protection system preventing an
outflow of dangerous flue gas to the room. The system consists of a built-in
temperature limiter (item 10, see Fig.14) which shuts off the main valve in the
gas/water unit and cuts off the fuel gas inflow to the burner when the chimney
draft is smaller than 0.01 “W.C.” (water column) or there is a back pressure in the
chimney. If there is an emergency shutdown of the water heater, you should
close any open hot water faucets. After 10 minutes, when the temperature limiter
32
ISU-217:2004
część angielska
is cooled down (time depends on the room temperature) the gas water heater will
automatically restart and hot water will flow to the faucets.
If the emergency shut-down process continues, check the chimney draft. Do not
make any modifications to the protection system. Eliminating or modifying the
protection system or damaging it may result in a dangerous or even lifethreatening outflow of flue gas to the room.
•
The Anti-fuel flow protection device is based on an ionization flame control and
eliminates gas inflow to the burner when there is no flame on the burner.
•
The guard against overheating of the heat exchanger, consists of temperature
limiter (item11, see Fig.14) which shuts off the gas inflow to the main burner and
the ignition burner when water temperature in the heat exchanger exceeds the
pre-set factory setting of 200° F.
ROUTINE PREVENTATIVE MAINTENANCE
WARNING: Turn off any electrical power supply, the manual gas control valve and the
manual water control valve before servicing.
The unit should be checked once a year or as often as necessary by a certified and
trained technician or licensed plumber. If repairs or service is required, such repairs
should likewise be done by a trained technician or knowledgeable plumber. The
following systems and parts should be checked at least once a year:
•
Venting system - should be checked annually. Clean and repair as needed.
•
Heat exchanger - in very hard water areas, periodic de-scaling may be
necessary to ensure longer life and higher heat transfer efficiency. To de-scale,
remove the heat exchanger from the heater and flush the heating coils with a descaling solution or acetic acid (concentration 10-20%). Let the de-scaling product
work for 10-15 minutes (if using
acetic acid let sit for 3 hours.)

•
Burner – clean the cover plates
on the burner segments with a soft brush (not a wire brush.) Pay special attention
to check that the cover plates and burner segments have not been damaged.
•
Periodic cleaning of the water filter: Should be done if the water flow rate is
noticeably reduced at the faucets or debris is commonly found in water supply.

Fig. 26 Periodic cleaning of the gas filter in the gas/water unit
If the gas flow rate on the main burner is noticeably reduced and the burner does not
light up, the gas filter should be cleaned.
-
Turn off the cold water and gas supply lines to the heater.
Check and clean the gas filter on the gas supply pipe before the heater.
If there is no gas filter on the gas supply pipe leading to the heater, the inner gas
filter in the gas/water unit may have become plugged.
Remove the gas/water unit, remove the inner gas filter and clean it , then re-install
the gas/water unit to the heater (see Fig. 26)
•
Check-up of protection equipment
-
Check-up of protection system against the outflow of flue gas to the
room
The temperature limiter (item 10, see Fig.14) is a protection device against
outflow of flue gas to room. The temperature limiter is preset for 185±5.4º F
To check the correctness of the setting of the temperature limiter:
-
Insert a thermometer in an empty metal container and fill it with water.
Remove the temperature limiter from its holder by undoing the screws and
place it in the container, immersing only the metal cap.
Heat the water up to 176º F at which point the temperature limiter should
cease to operate.
Continue to heat the water up to 190.4ºF. At this temperature the
temperature limiter should operate.
The properly-operating temperature limiter should disconnect the contacts within the
temperature range of 179.6 ºF – 190.4º F.

set for 185±5.4 º F. To ensure that it is operating properly, follow the steps in
the section above. A properly-operating temperature limiter should disconnect
the contacts within temperature range of 179.6 º F – 190.4º F.
•
A periodic (at least yearly) visual check of the pilot and burner flames should be
made and compared with the pictures on pages 17 & 18 of these instructions.
•
A periodic visual check should be made (at least yearly) of the area around to
heater to make sure it is free from combustible material, gasoline and other flammable
vapors and liquids. Be sure that there is nothing obstructing the flow of combustion and
ventilation air.
GENERAL REPAIR/SERVICE DIAGNOSIS
During production and assembly, all ThermElite tankless gas water heaters undergo
numerous quality assurance tests. However, occasionally during such testing some
disturbances may occur. To make it easier to define an eventual malfunction in the
heater’s operation and to shorten the repair time, helpful information has been listed in
the table below.
Before starting any repairs, please do the following:
•
•
•
•
Check the rating plate on the side of the front cover to ensure that the fuel supply
(NG or LP) matches the model heater (P=Propane, N=Natural Gas.)
Check that the inlet gas pressure meets at least the required minimum.
Check that the sub-atmospheric pressure in the chimney is between 0.01 –0.06
inches water column.
Check for weak batteries on the battery status indicator (on heater TE125X.)

Diagnosis of ignition system
Once a hot water faucet is opened, water flowing through the heater should ignite the
burner as a result of the following process:
-
Joining of contacts in the micro switch.
Sparking between the ignition electrode and the spring located on the ignition
burner pipe.
Electrical current to coil #1 opens valve #1 in the pressure differential valve.
Gas lights-up on the ignition burner an ionization current is being sensed by the
monitoring electrode.
Electrical current to coil #2 causes valve #2 in the pressure differential valve to
shut off.
Opening of the main gas valve as a result of a pressure differential above and
beneath the membrane located in the pressure differential valve.
Ignition of the main burner assembly.
Check-up of the ignition system
If the ignition system does not operate properly, it should be checked according to the
steps below.
1.
2.
3.
4.
5.
Check that there are no loose or broken electrical connections.
Using a voltmeter, connect to the negative (-) end located:
in heaters TE80X and TE125X - the spring in the battery compartment.
in heater TE80H and TE125H – hydro-generator conductor in white
insulation.
Connect the voltmeter to the positive end (+) end located:
in heater TE 80X and TE125X – the sheet in the battery compartment.
In heater TE80H and TE125H – hydro-generator conductor in red
insulation.
Measure the voltage
in heater TE80X and TE125X – the battery voltage is 1.5 VDC.
in heater TE80H and TE125H – hydro-generator voltage at a resistance of
10Ω and water flow of 0.79 gal/min is 1.3 – 1.6 VDC.
Measure the voltage of the ignition system. The system works properly within the
range of 0.9 – 1.5V.
6. Check the voltage at the temperature limiter device which protects against the
outflow of flue gas to the room (voltage like on a battery).
7. Check the voltage at the temperature limiter device which protects against the
heat exchanger overheating by cutting-off fuel to the main burner (voltage like on
the battery).
8. Check the voltage on the spark generator clamp (voltage like on the battery)
9. Join the micro-switch contacts. Joining the contacts should cause sparking
between the ignition electrode and a spring on the ignition burner pipe
10. Check the voltage on the clamps of coil #1 (the system operates properly at a
voltage of 0.9 – 1.5 V).
36
ISU-217:2004

11. After the ionization current is being sensed by the monitoring electrode (after the
flame is lit up), check the voltage on the clamps of coil #2 (the system operates
properly at voltage of 0.9 – 1.5 V).

WARNING:
A water heater that will be used to supply potable water shall not be connected to
any heating system or component(s) previously used with a non-potable water
heating system.
When the system requires water for space heating at temperatures higher than
required for other uses, a means such as a mixing valve shall be installed to
temper the water for those uses in order to reduce scald hazard potential.
