Safety and energy conservation are factors to be considered when selecting the water temperature setting. Water temperatures above 125°F can cause severe burns or death from scalding. The thermostat is adjusted to its lowest temperature position when shipped from the factory. Be sure to read and follow the warnings outlined on the label pictured below.

Water temperature over 125°F can cause severe burns instantly or death from scalds. Children, disabled and elderly are at highest risk of being scalded. See instruction manual before setting temperature at water heater. Feel water before bathing or showering. Temperature limiting valves are available, see manual.

Time/Temperature Relationship in Scalds

• The chart shown above may be used as a guide in determining the proper water temperature for your home
• DANGER! Households with small children, disabled, or elderly persons may require a 120°F. or lower temperature setting to prevent contact with”HOT” water.
• Maximum water temperature occurs while burner is on. To find water temperature being delivered, turn on a hot water faucet and place a thermometer in the water stream and read the thermometer.
• The temperature of the water at the outlet of the water heater can be regulated by setting the temperature on Remote Control. The remote control was set at 110°F before it was shipped from the factory.
• The illustration to the bottom left illustrates the Remote Control and how to adjust the water temperature.
• NOTICE: When this water heater is supplying general purpose hot water requirements for use by individuals, a thermostatically controlled mixing valve for reducing point of use water temperature is recommended to reduce the risk of scald injury. Contact a
• licensed plumber or the local plumbing authority for further information.
• NOTICE: The factory recommended operating temperatures are between 90°F and 140°F.

DANGER!
NATURAL GAS AND LIQUEFIED PETROLEUM MODELS

Both liquid propane gas (LPG) and natural gas (NG) have an odorant added to aid in 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 LPG 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. Always check with commercial leak detector or soapy water.

• Gas detectors are recommended in LPG and NG applications and their installation should be in accordance with the detector manufacturer’s recommendations and/or local laws, rules, regulations or customs.
• Water heaters utilizing LPG are different from NG models. A NG water heater will not function safely on LPG and vice versa.
• No attempt should ever be made to convert the water heater from NG to LPG. To avoid possible equipment damage, personal injury or fire, do not connect the water heater to a fuel type not in accordance with the unit data plate; propane for propane units and natural gas for natural gas units. These units are not certified for any other fuel type.
• LPG water heaters should not be installed· below grade (for example, in a basement) if such installation is prohibited by federal, state and/or local laws, rules, regulations or customs.
• Propane or LPG 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.
• It is recommended that more than one method, such as soapy solution, gas detectors, etc., be used to detect leaks in gas applications.

Notice: If a gas leak is present or suspected:

• DO NOT attempt to find the cause yourself.
• DO NOT try to light any appliances.
• DO NOT touch any electrical switch.
• DO NOT use any phone in your building.
• Leave the house immediately and make sure your family and pets leave also.
• Leave the doors open for ventilation and contact the gas supplier, a qualified service agency or the fire department.
• Stay away from the house (or building) until the service call has been made, the leak is corrected and a qualified agency has determined the area to be safe.

WARNING!
For your safety, the information in this manual must be followed to minimize the risk of fire or explosion, electric shock, or to prevent property damage, personal injury, or loss of life.

TECHNICAL DATA AND DIMENSIONS

WATER HEATER INSTALLATION

Mark the wall with a dark mark, then drill three holes with a diameter of 8mm and a depth of 2 3/4 inch, then insert three 1/4 x 2 inch expansion screws into the hole and tighten the screws with a wrench.
Hang up the water heater, screw on the 1/4 inch nut and fix the heater to the wall.
Incorrect installation of the heater will affect the normal use of the water heater.

PLUMBING NOTES

• When connecting the hot water supply to the fixtures of the property a minimum of 6.5ft of pipe work must be used between the outlet of the water heater and first outlet (shown below).
• The hot water line should be insulated with pipe insulation.
• When the installation is completed the temperature is to be tested at the outlet to confirm the water temperature does not exceed the required 122°F (50°C) setting.
• Water pipe size is nominal 1/2 inch from hot water outlet to the first outlet.
• Gas pipe size in nominal 3/4 inch.

CONNECTING THE WATER

• All pipes, pipe fittings, valves and other components, including soldering materials, must be suitable for potable water systems.
• A manual shut off valve must be installed on the cold water inlet to the water heater between the main water supply line and the water heater.
• Only a gate valve or a ball valve is to be used on the cold water supply.
• Check the cold water pressure. If above 145 psi an approved limiting valve must be fitted.
• Before installing the water heater, flush the water line to remove all debris, and after installation complete, purge the air from the line. Failure to do so may cause damage to the heater.
• To prevent water heater water system damage caused by excessive pressure. At the water outlet of the water heater, it is necessary to install an appropriate pressure relief valve to protect the water system and user safety. The pressure relief valve complies with ANSIZ21.22/CSA 4.4
• In the hot water system, the temperature rises continuously, and the volume of water expands.
• If the system is equipped with an expansion tank or a flexible connection bellows can absorb a part of the expansion amount, the expansion tank or the soft connection bellows cannot absorb the pressure relief valve needed to protect the pressure relief valve to protect The entire system prevents breakage of pipes and other components, so the relief valve pressure setting is generally selected to be slightly less than the maximum pressure (Pmax) that the entire system can withstand.
• In addition, the pressure cannot be the same as the normal operating pressure, too close to the normal operation of the pressure relief valve will frequently pressure relief, lower temperature and pressure relief valve service life.
• In order to prevent the damage of the temperature probe or control system and cause the continuous heating of hot water to reach 212°F (100°C) vaporization, it is necessary to install a temperature and pressure safety valve, and the temperature and pressure
• valve temperature reaches 210°F (99°C) to relieve the pressure, thereby protecting the entire system. So the safety valve temperature is generally set to 210°F (99°C).
• There is a wire mesh filter to discourage debris from entering your heater. Clean filter after initial installation to ensure no debris from the pipe work has clogged it.

CONNECTING THE GAS

SIZING AND CONNECTION SUITABILITY

• Check the gas type label to make sure that the unit was built for the type of gas you will be using, and that the gas inlet pressure is within the appropriate range.
• Gas pressure below the specified range for the water heater and/or insufficient gas volume will adversely affect performance.
• Inlet gas pressure must not exceed the maximum values, gas pressure above the specified range will cause dangerous operating conditions and damage the unit.
• Until testing of the main gas line supply pressure is completed, ensure the gas line to the water heater is disconnected to avoid any damage to the water heater. Always use approved connectors to connect the unit to the gas line. Always purge the gas line of any debris before connecting to the water heater.
• Install a manual gas shut-off valve between the water heater and the gas supply line.
• The regulator is preset to factory standards. It is computer controlled and is not to be adjusted by any person other than a licensed professional.
• When the gas connections are completed, perform a gas leak test either by applying soapy water to all gas fittings and observing for bubbles or by using a gas leak detection device.

PRESSURE AND GAS LEAK TESTING

• Shut off the manual gas valve on the supply gas line.
• Open a tap/outlet. The unit should turn on and the air in the gas pipeline should be purged.
• Leave the tap/outlet running until the unit shuts down due to lack of gas supply. Then turn off the tap/outlet.
• Remove the screw on the pressure port located on the gas inlet of the water heater shown in the diagram to the right.
• Connect the manometer to the pressure port.
• Re-open the manual gas valve. Check to see that there are no gas leaks.
• Open some of the fixtures that use a high flow rate to turn on the water heater.
• Check the inlet gas pressure in the postiton shown in the circle above. When the heater is at maximum capacity, the gas pressure point must be within the appropriate range.

PRESSURE RELIEF VALVE

• Please use sealant tape to seal the thread of pressure relief valve, then install it into Tee valve G3/4 outlet (as shown above).
• Please use sealant tape to seal the thread of the water outlet, then install pressure relief valve, tee valve and water outlet together. Please select a suitable position to install (as shown above).
• Please note that the outlet of the pressure relief valve cannot face upward, otherwise it will never fully drain.
• Anti-fouling and anti-scaling, dirt will directly affect the normal function of the safety valve function. The drain pipe must match the drain port to ensure that the valve does not interfere with the normal operation of the valve.
• The pressure relief valve outlet can be installed horizontally or vertically, do not install the pressure outlet facing upwards, otherwise it cannot work normally. It is forbidden to block its outlet.
• The dirt will directly affect the normal function of the safety valve function. It requires hot water system maintenance of anti-fouling and anti-scaling cleaning.
• The user must check the relief valve at least once a year. When checking, turn off the water heater’s power supply and gas. Turn on the water inlet switch to create pressure in the water system. Then gently open relief valve handle until there is water coming out and then gently close it, if there is no water coming out, this indicates that the valve is invalid, immediately turn off the water heater switch and contact support at support@eccotemp.com
• Before operating the handle, check the discharge line connecting the valve to ensure that the water drained from the valve can be drained to a suitable place.
