• Keep eyes away from the flame indicator window at a minimum safety distance of 300mm during ignition. If the first attempt of ignition fails, wait 10-20 seconds before the next attempt.
• Prevent No-Water Burning in The Heater
• After each shower, make sure that the flame is extinguished when the valve is closed. If the flame still exists after the water valve is closed, something must be wrong with the heater. Switch off the gas valve immediately and contact the service center. Otherwise the heater may be damaged by overheating and then may cause a fire hazard.
• Do Not Use The Heater Water for Drinking
• As there is always residue in the heater, the water supplied by the heater is only for general usage, not for drinking.
• Dealing With The Abnormal Conditions
• Stop the heater when there is strong adverse wind blowing. Strong winds can cause igniton failure or sudden flame out.
• In case of abnormal burning ( e.g. flame-back, flameout, yellow flame or black smoke, etc.), unusual smell, noise or other abnormal situations, keep calm and turn off the gas valve and contact the service center or the gas dealer.
• NOTICE

Reduce The Chance of Getting Burned

• After shower, please turn off the gas valve and run the water until cool water is flowing through the heater. Then turn off the water inlet valve.
• Freezing Prevention
• Under the circumstance of low temperature, please drain the water remaining in the heater completely after each use. Otherwise the water may freeze and cause damage the heater.
• The following phenomenon are normal:
• When the water pressure is lower than 3psi, the heater cannot be ignited.
• The drain valve/pressure relief is dripping. When the water pressure is too high, the drain valve will release water so as to reduce the pressure to protect the heater.
•  When the heater is supplying hot water to too many points at the same time, the hot water flow will be reduced, and under exceptional circumstances no hot water will come out at all.
• The gas water heater is for point of use, for temporary water heating and not for connection to a permanent inlet water connection or for connection to a water distribution system to supply multiple outlets.

SAFETY PRECAUTIONS

1. Always check water temperature by hand before entering shower or bath. The temperature may have been changed. Do not touch the unit cover or the flue outlet while in use.
2. Do not insert objects into the flue outlet. On colder days steam may discharge from the flue outlet. This condition is normal for high efficiency appliances.
3. The vent/air intake should be positioned away from flammable materials such as trees, shrubs, etc.

HOT WATER RISK

1. Hot water is dangerous, especially for the young and the elderly or the infirm. The EZ Tankless water heater allows you to precisely control the temperature of your hot water, ensuring safe water temperature. Water temperature over 125°f can cause severe burns instantly or death from scalding.

2. Hot water can cause first degree burns with exposure for as little as:
   3 Seconds at 140°f
   20 Seconds at 130°f
   8 Minutes at 120°f

3. Test the temperature of the water with your elbow to ensure adequate temperature before placing a child in the bath or shower.

4. Do not leave children or an infirm person in the bath unsupervised.

SCALDS-FIRST AID GUIDANCE

1. Remove clothing – remove all wet clothing, quickly, as wet clothing retains the heat.
2. Apply cold water for 30 minutes – immediately submerge the burnt area in cold water for 30 minutes to reduce the heat in the skin, preventing deeper burning. Never use butter, oils, or ointment to cover the burn, as they may retain the heat.
3. Keep the individual warm – place a blanket around the affected indivdual.
4. Seek medical advice – call your medical advice hotline and describe the scalding properties, follow their directions to provide further treatment if necessary.

INITIAL SETUP AND OPERATION

Note: These steps should be followed for every new location or water source

1. DIAL POSITIONING (PRE-FIRST IGNITION)

   • a. Water Flow Dial – The water temperature dial should be first set to the “low” setting.
   • b. Winter/Summer Dial – The winter/summer knob should be first set to the “summer” setting.
   • c. Flame Dial – The flame dial should be first set to the “low” setting.

2. GAS SUPPLY

   • Gas supply to the EZ 101 unit should only be propane (lpg) regulated to a pressure setting of 11”WC. The EZ 202 Natural Gas requires 8” WC. Lower or higher pressures beyond this value will deliver inconsistent ignition and operation and are not recommended.

3. WATER SOURCE

   • Inlet water source should be at least 1 gpm filtered water at a minimum pressure of 8PSI. Water flow or water pressure values less than these recommended may result in unit failing to ignite.

4. ADJUSTMENTS FOLLOWING FIRST IGNITION
   Note: These adjustments should be made with the unit running and heating water.

   • a. To increase water flow, slowly turn water temperature dial counter clockwise. If, while increasing water flow, the EZ 101 flames out, slowly return dial clockwise until unit reignites.
     Stop! At point of reignition you have reached the maximum flow rate as provided by your chosen water inlet source.

   • b. To increase water temperature, slowly turn the “flame” dial clockwise. If you reach the maximum flame level and the water is still not warm enough, return the “flame” dial to the low setting and attempt “step c”. When desired water temperature is set, do not reset the dials until a new water source is provided.

   • c. Turn the winter/summer dial counterclockwise to the next setting. The dial will lock into place when turned to each setting. With the dial at the new setting return to step “b” and continue to find desired temperature setting.

CONTROL DIALS INFORMATION

1. WATER FLOW DIAL
   The water temperature dial provides the greatest level of control over ignition level. This dial controls water flow through the system. The EZ 101 uses a water pressure activated valve to control the electronic ignition and gas flow through to the burners. If the user sets the water flow dial at the “high” setting (highest amount of water flow) but has a water source with less than 2gpm, there will not be a large enough build of pressure in the water/gas diaphragm to engage the pressure valve. This is why it is always recommended to set the water flow dial to “low” during initial setup/first ignition.

2. SEASONAL MODE DIAL
   The seasonal mode dial will provide the largest flucuation in delivered water temperature. This dial regulates the internal burners within the system. Selecting between 1 oe 2 burners, the available options include summer or winter respectively.

3. FLAME DIAL
   The flame dial will provide the greatest level of control in water temperature. When adjusting water temperature to that desired, the flame dial should be used between each burner selection to reach the desired temperature setting.

RECOMMENDED EZ101 MAINTENANCE

1. CHECK THE GAS HOSE AND REGULATOR FOR ANY DEFECTS
   Propane regulators, especially single stage regulators, defect at a high rate predominantly due to age. Most single stage regulators will eventually allow a higher pressure than the required 11”WC by the EZ 101. When this hap-pens the unit will not ignite. This is the most common fault that causes ingnition failure.

2. CHECK THE EXHAUST VENT FOR BLOCKAGE REGULARLY
   Debris, animals, or insects may enter the exhaust vent at anytime. Be sure to regularly check the exhaust vent for any blockage. A blockage of the exhaust vent will cause inconsistent water temperatures as well as potential damage to internal components.

3. CLEAN INLET WATER FILTER SCREEN REGULARLY
   Located just inside of the water inlet fitting on the bottom of the EZ 101 is a filter screen. This screen is used to keep sediment and small debris from entering the heat exchanger. Be sure to regularly check this screen for any debris that it may have caught. Remove the screen from the inlet using a small pick or screwdriver, blow away or rinse away any debris that may have accumulated and reinstall the filter screen into the water inlet before next use.

4. FLUSH UNIT ONCE A YEAR
   With the heating of water through a heat exchanger comes the build up of minerals over time throughout the water heater parts and components. It is recommended to flush your tankless water heater with distilled white vinegar at least once per year when used on a regular basis, to ensure continued use and to avoid parts damage.

5. ALWAYS KEEP COVER OF UNIT CLEAN
   The cover of your water heater will become hot during use. It is not recommended to place any stickers, magnets, or other decorative material on the cover of the EZ 101. Be sure to wipe away any dirt or debris that may be on the cover before each use.

TROUBLESHOOTING

THE WATER HEATER FAILS TO IGNITE/HEAT THE WATER

1. Check that the batteries are installed correctly and hold a positive charge.
2. Detach your gas supply (turning off gas supply will not release built up pressure so you must detach gas supply to perform troubleshooting.)
3. Attempt running water through the unit with the gas supply detached. If your unit sparks the igniter without the gas supply attached you may have a gas regulator with an outlet pressure too high. Recommended outlet pressure is 11”WC.
4. If the unit fails to spark the igniter with the gas supply detached, there may be an issue with the microswitch used to control the electronics.
5. Remove the dials from the front of the unit
6. Remove the cover from the unit – screws are located at bottom rear corners
7. With cover removed, locate red and blue wires running from computer board (bottom left corner) to the micro switch (front and center). The wires are connected with using white connectors.
8. Detach the white connectors from each other, thus separating the computer board and micro switch.
9. Using a “flat-blade” screwdriver, complete the circuit between the two prongs located inside the white connector on the computer board side of the red and blue wires.
10. If a spark is produced when doing so, the unit micro switch has failed. If no spark is produced,
    the unit computer board or battery compartment is faulty.

• To test for a faulty battery compartment With unit cover removed, remove the red and black wires from the top of the battery compartment. Tape two “D” cell batteries in a series (configuration as follows: +[battery#1]- +[battery#2]-). With the batteries taped together securely, hold the red wire to the positive side of the batteries and the black wire to the negative side of the batteries. Again touch the “flat-blade” screwdriver to the two prong located inside the white connector on the computer board side of the red and blue wires. If a spark is produced, a new battery compartment is required. If no spark is produced a new computer board is required.
• Q. DOES THE IGNITER SPARK?
• B. YES:

1. If the igniter sparks but the unit fails to flame up, first check that you are using alkaline batteries. If the batteries are weak they will not open/hold open the gas solenoid – this results in gas being restricted from entering the burners.

2. If the heater contains brand new alkaline batteries and sparks, yet does not ignite, a faulty gas solenoid valve may be present.
   To test the gas solenoid:
   Shut off unit and remove all gas supplies from the water heater. Remove the gas solenoid by removing the 2x philips screws holding it in place on the gas assembly. With the gas solenoid removed, apply a small amount of pressure on the valve (push the valve about 1/4 of the depth and it will drop into the solenoid). Trip the igniter by running water through the system, or lift the pressure plate off of the microswitch. With you finger resting on the solenoid and the igniter engaged, electricity should flow through the solenoid and pull the valve into the solenoid. If this does not happen, a new gas solenoidis required.

3. If the igniter sparks, the unit flames up but extinguishes itself in 5-10 seconds, a faulty limit switch may be present. In order to resolve, bypass the limit switch by completing the circuit between its two wire connections. With that circuit completed before again attempting to run the water heater.

4. If the unit fires and remains lit with the limit switch bypassed, order a new limit switch from our parts page on our website: [ http://www.eztankless.com] For complete and up to date troubleshooting and self help videos please visit: http://www.eztankless.com/support/ez-101-troubleshooting/
