NOTICE: The factory recommended operating temperatures are between 90°F and 140°F.
**DANGER!
NATURAL GAS AND LIQUEFIED PETROLEUM MODELS
** Both LP and natural gas 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 LP or natural gas, 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 LP and natural gas 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 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 natural gas 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 unit data plate; propane for propane units and natural gas for natural gas units. These units are not certified for any other fuel type.
LP 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 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.
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.

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 6.5 FT 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 armaflex or similar 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 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 pressure relief valve cannot face upward, otherwise it will always leave some water inside.
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, but it cannot make 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 out and then gently close, if there is no water out, indicating that the valve is invalid, this time should immediately turn off the water heater water switch and ask the service personnel to deal with.
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.

CONNECTING THE ELECTRIC
The water heater must be electrically grounded. Do not attach the ground wire to either the gas or water piping.
The water heater requires an AC 120V 60Hz.
The weather-proof power point should be no more than 3FT from the base of the water heater for easy access.
Install a power switch so that the electrical power can be switched off if necessary.

PCB ERROR CODES

Troubleshooting :
When the water heater fails, the display will display the fault code, while the buzzer will issue continuously “Beep” alarm sound, please follow the table to deal with accordingly

the gas is correctly connected and then use
E2| False fire fault
E3| Thermostat protection
E4| Water temperature probe fault
ES| Fan fault, before the ignition, fan speed is detected for 8s less than 1000 r/min or when burning fan speed for 6s less than 600 r/min continuously.
E6| Over-heating protection. Please check wether the water pressure is too low, confirm the water pressure is over starting pressure and then use
E7| Solennoid valve fault
E8| Flue jam fault
EN| The set shutdown time has been reached

If any codes appear in the chart above and the water heater is functioning normally, restart the water heater. After restarting and it is not operating normally, please notify the after-sales service staff maintenance.

THE FOLLOWING CONDITIONS ARE NOT A FAULT

encountered the cold air and then is condensing into a white mist.
Flow rate of generated hot water is too small to achieve requested water temperature| Hot water flow is too low to ignite the water heater.
The water heater will not turn on if the flow is too low and then the water will become cold. Raise the flow rate higher to activate the heater.
Can’t supply high enough temperature in winter| The incoming water temperature is very low and the water adjustment knbo is already turned to maximum. The set temperature may be more than the heating capacity allows. Please adjust the flow lower to allow the water to heat to higher temperatures.
Water is too hot during the summer| Incoming water temperature is too high and the incoming flow is too low. It may cause the hot water to be too hot. Please adjust the flow to be more to lower the temperature.
The water heater turns off after 40 minutes| In order to prevent hypoxia, some models have a 40 minute timer protection function. When you continuously use the water heater for 40 minutes, it will turn off. Please turn off the tap and restart.
Close the hot water valve, but the fan does not stop immediately| The fan has a delay in the shutdown fucntion in order to completely clean the water heater exhaust to ensure the safety of users.
Open the hot water valve, but hot water does not flow immediately| There is a distance from the water heater to the outlet, so the cold water in the line must flow out before the hot water reaches your outlet. The farther the distance from the water heater, the more time it takes to receive hot water.
There is always some water from the drain valve| This is because the inlet water pressure is too high and the drain valve will work to release the high pressure. Try to reduce the inlet water pressure by turning down the gate valve or the ball valve until water leakage stops.
