SAFETY PRECAUTIONS

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.
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.
The vent/air intake should be positioned away from flammable materials such as trees, shrubs, etc.

HOT WATER RISK

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.
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

Test the temperature of the water with your elbow to ensure adequate temperature before placing a child in the bath or shower.
Do not leave children or an infirm person in the bath unsupervised.

SCALDS-FIRST AID GUIDANCE

Remove clothing - remove all wet clothing, quickly, as wet clothing retains the heat.
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.
Keep the individual warm - place a blanket around the affected individual.
Seek medical advice - call your medical advice hotline and describe the scalding properties, follow their directions to provide further treatment if necessary.

INITIAL TEMPERATURE SETTING: BETWEEN 40-50°C
WATER SOURCE
Inlet water source should be at least 1 GPM filtered water at a minimum of 8PSI. Lower water flow or a lower water pressure may result in the unit failing to ignite.
AFTER FIRST IGNITION ADJUSTMENTS
If you use mixing valves anywhere in the home we do recommend setting the heater with a lower water temp setting in combination with using more hot water in the mixture. This will guarantee that there is at least 1GPM running through the heater.

SPECIAL NOTES INSTALLATIONS

WELL WATER INSTALLATIONS
Due to the fluctuation in water pressure when using a well water system, users may experience fluctuations in water temperature. Fluctuations can be rectified with use of a water pressure regulator. When using a well system with a pump switch set to 40-60PSI, it is best to set your water pressure regulator at 45PSI. Alternatively, if using a pump switch set to 30-50PSI, it is recommended to set your water pressure regulator at 35PSI.

BASEMENT INSTALLATIONS IN COLD WEATHER CLIMATES
The EZ Deluxe does not come provided with freeze protection. If exposed to freezing temperatures, the water in the heat exchanger can freeze and can damage the pipework within the heat exchanger. When performing a basement wall installation, it is recommended to install on a sub-frame (e.g 2x4) to create an air buffer between the wall and the back of the unit. This is to reduce the risk of freezing through direct contact with basement walls. Typically basement walls are poorly insulated & thus surface temperatures can be much colder than the ambient room air.

MIXING VALVES
Modern mixing valves use a thermostatic temperature valve to control hot and cold water to faucets, showerheads, and tub fixtures. These devices can often cause an issue when used in conjunction with a tankless water heater set at a high temperature. When the water temp is set above 110-120°F, these valves will add cold water to adjust the temperature to keep from scalding. An unwanted effect of this is that the hot water flow may drop below required levels to keep the heater running. There are a number of recommendations to reduce the risk: a. Lower the water temperature setting on the water heater. Suggested settings of approx. 42°C are ideal in many scenarios. b. Adjust the temperature setting on the mixing valve. (See manual for each individual fixture.) c. Replace showerhead with a high flow rate showerhead. It is common for a mixing valve fixture used in conjunction with a water-saving showerhead to cause ignition issues with most tankless water heaters. Be sure to use a showerhead with at least a 2GPM flow rate in conjunction with a mixing valve fixture to limit issues.

USE A SURGE PROTECTOR
The EZ Deluxe uses many sensors that are based on resistors. It is important to protect the electronics of the EZ Deluxe system by plugging the unit's power cord into a surge protector.

This drawing is not intended to portray a complete installation system. The project engineer and/or installation contractor should determine the necessary components for the configuration of the system being installed.

This drawing does not imply compliance with local building code requirements. It is the responsibility of the project engineer and/or contractor to ensure that the installation is fully in accordance with the applicable building code through the authority having jurisdiction. Obtain approval with local building code officials prior to installation.

RECOMMENDED EZ DELUXE MAINTENANCE

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 Deluxe. When this happens the unit will not ignite. This is the most common fault that causes ignition failure.
CHECK THE EXHAUST VENT FOR BLOCKAGE REGULARLY
Debris, animals, or insects may enter the exhaust vent at any time. 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.
CLEAN INLET WATER FILTER SCREEN REGULARLY
Located just inside of the water inlet fitting on the bottom of the EZ Deluxe 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.
FLUSH UNIT ONCE A YEAR
With the heating of water through a heat exchanger comes the buildup 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.
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 Deluxe. Be sure to wipe away any dirt or debris that may be on the cover before each use.

TROUBLESHOOTING

WHEN THE HOT WATER TAP IS OPENED, AND THE EZ DELUXE IS NOT RESPONDING.
If you are running water through the system, but do not see a showerhead image on the display, the heater is failing to sense the water flow. This will require one of the following to resolve the issue:

Flush the unit. Flushing the unit with Distilled White Vinegar will help to clean the magnetic turbine located inside of the flow sensor housing.
Disassemble and clean the flow sensor housing by hand. Please call our tech support department for access to our tech support videos (Note: Tech support videos are intended for advanced technicians only).
Replace the flow sensor housing. If after cleaning the flow sensor housing by hand the system still fails to sense water flow, the flow sensor housing may need to be replaced.

THE DISPLAY SHOWS AN ‘E0’ ERROR CODE WHEN TRYING TO IGNITE.
This is an error on the inlet water temperature probe. We recommend trying to clean it before replacing it. It is located on the flow sensor housing located on the bottom right of the unit where the water first enters. It will have a set of two black wires coming off of it and held in by one or two screws. Turn the water off to the unit then remove the two screws holding the temperature probe in place. Once removed, clean the probe with white vinegar and reinstall it. If the unit continues to show an E0 after cleaning the probe then it will need to be replaced.

THE DISPLAY SHOWS AN ‘E1’ ERROR CODE WHEN TRYING TO IGNITE.
Does the unit show an ‘E1’ error code every time the unit tries to ignite or sporadically?

Should the unit be showing the ‘E1’ error code only occasionally, we recommend flushing the system with distilled white vinegar.
Should the unit be showing ‘E1’ every single time it tries to fire: A. Check to make sure that only EZ Tankless vent is being used. Be sure that the vent is installed in a horizontal manner, through an exterior wall and vented outdoors. Check that there is nothing blocking the proper flow of air through the intake or exhaust. B. After verifying proper flow of air through the vent system, remove the front cover of the unit (Be careful as the display should remain attached for this test.) Once the front cover is removed, while viewing into the combustion chamber windows, open a water source to allow the heater to try to fire. If the unit fires on the right side of the burners, but only the right side before going to the ‘E1’ error code, your unit will need a motherboard replacement.
If your unit is showing ‘E1’ error code and the above steps have been taken to address the issue without resolution, please call EZ Tankless Tech Support for further assistance.

THE DISPLAY SHOWS AN ‘E2’ ERROR CODE WHEN TRYING TO IGNITE.
Please call EZ Tankless support for assistance.

THE DISPLAY SHOWS AN ‘E4’ ERROR CODE WHEN TRYING TO IGNITE.
This is an error in the fan sensor, fan motor, or motherboard. Remove the front cover of the EZ Deluxe, keeping the display wires attached. Locate the fan in the bottom left corner of the unit. Run a hot water tap. Watch the fan blades and observe how they are spinning. If the fan increases to high speed when the unit senses water flow, but the unit shows an ‘E4’ error code, the fan sensor is faulty and requires replacement. If the fan spins very slowly and the unit goes to E4, the motherboard needs to be replaced. If the fan does not spin at all, the fan motor is faulty and requires replacement.

THE DISPLAY SHOWS AN ‘E5’ ERROR CODE WHEN TRYING TO IGNITE.
This is an error of the limit switch or limit switch wire. Remove the front cover of the EZ Deluxe, keeping the display wires attached. Locate the limit switch in the top left corner. Remove the wires from the limit switch. Complete the circuit between the two wires using a piece of wire, or by sliding the two tabs together (A video of this test can be found on our website). Run water through a hot water tap connected to your EZ Tankless Deluxe unit kit. If the unit fires and runs while the wires are “jumped”, a new limit switch is required. If, after jumping the limit switch wires, the unit still returns an ‘E5’ error code, the thermal fuse in the wire may have been blown.

To Diagnose: Follow the wire back to the motherboard. Remove the wire from the motherboard, and using a flathead screwdriver, complete the circuit between the two prongs inside of the socket from which the limit switch wire had been removed. If the unit runs as it should, a new limit switch is required.

THE DISPLAY SHOWS AN ‘E6’ ERROR CODE WHEN TRYING TO IGNITE.
This is an error on the outlet water temperature probe. We recommend trying to clean it before replacing it. It is located to the left of the fan on the outgoing water line. It will have a set of two white wires coming off of it and held in by one bolt. Turn the water off to the unit then remove the bolt holding the temperature probe in place. Once removed, clean the probe with white vinegar and reinstall it. If the unit continues to show an ‘E6’ after cleaning the probe then it will need to be replaced.
