Function
The water heater is used to produce instant hot water. The
removal of hot water can be performed by multiple taps.
By turning on the relative tap, the main burner switches on heating
the water that passes.
1.After adjusting the temperature, the traditional knob control gas
water heater cannot keep the setting temperature constant due to
the fluctuation of water pressure and air pressure.
Due to its digital control valve and more advanced control system,
the controller can control the opening of the proportional valve ac
cording to the increase or decrease of the water temperature dete
cted by the temperature sensor , in case of water pressure or air
pressure fluctuation, so as to control the gas flow rate. Therefore,
the hot water outlet temperature can keep the setting
temperature constant.
2.The traditional knob control gas water heater will have high CO
rate under high pressure due to the unstable air pressure
supplied.
However, for this type of gas water heater with constant
temperature function, because the gas valve has a pressure
stabilizing fun ction, when the gas pressure is too high, the valve
will keep the pr essure at the outlet of the valve stable, then the
CO rate can be c ontrolled in a low range.
Usage
Ensure that the gas tap and all water taps are switched off
-
Turn on the Main gas supply tap or that of the gas tank if using
Liquefied Petroleum Gas (L.P.G.)
-
Open the gas tap,not supplied with the device,placed immediat
ely before the water heater on the gas input pipe
-
Press ON/OFFbutton,the gas water heater will be in standby s
tatus.Press UP or DOWN button to set the temperature of wate
r outlet (Fig 7). Press UP or DOWN button for one time,then t
he setting temperature will increase or decrease 1℃accordingl
y.When long press UP or DOWN button for every 0.3 seconds,
the setting temperature will increase or decrease 1℃.Tempera
ture setting range can be 35-60℃
-
When the gas water heater is connected with water supply,the
ignition pin will start to work and ignite the main burner.
-
If disconnect the water supply (turn off the water tap)or press
ON/OFFbutton to turn off the gas water heater,the burner will
automatically shut down.Then the device awaits another heat
ing request.
If after 60 seconds it does not switch on, the controller detector
interrupts the flow of gas and blocks the device.
To reuse the device after it has been blocked, close the hot
water extraction tap and then reopen it to restart the sequence.
If the main burner accidentally switches off, the device will
attempt to turn it on again.
If within 60 seconds the device does not function it is blocked .
The device is built to function with normal water pressure; in add
ition, a temperature selector B is also supplied.
Rotate the knob completely to the left to obtain the minimum
water output or completely to the right for the maximum water
output.
When the water heater is not used for long periods close the
gas supply tap or the LPG gas valve on the tank.
For the best operational results, it is recommended to have
aqualified technician service the machine at least once a year.
DANGER OF FREEZING
If there is a possibility that the area where the device is stalled
could reach below 0°C, the device must be emptied of all water
contain ed. In case of freezing conditions disconnect the
incoming water pipe to drain the water heatercompletely.
MAINTENANCE
To maintain the machine at maximum efficiency, have qualified
personnel perform a maintenance check at least once a year.
Before cleaning or performing maintenance,
opening or disassembling the panels, switch off the device and
turn off the gas supply. Check the main burner and the pilot
flame, the ignition electrode, the safety valve and that there is
no leakage.
Check that there is nothing obstructing the passages within the
exchanger smoke channel.
To clean the outside of the panels, utilize a cloth with soap and
water.
Do not use solvents, powders, or abrasive sponges.
Do not clean the device and/orits parts with flammable material
s (e.g. petrol, alcohol, diesel etc.).
Troubleshooting: problems and solutions
Fault code
It will immediately shut down all gas channels
and display the fault code on the screen whe
n the controller detects a fault.
Fault Code meaning
E1:Ignition failure (Including ignition failure caused by low voltage).
E2:Ignition failure for the second time. (Including ignition failure
caused by low voltage).
E3:MCU self-check fault or EEPROM fault or wires fault.
E4:Temperature sensor of water outlet has open circuit or short
circuit.
E5:Temperature sensor of water inlet has open circuit or short
circuit(When the temperature sensor of water inlet is include d).
E6:False fire.
E7:The overheating thermostat has open circuit.
E8: Temperature of water outlet is over
85
℃
℃
.
E9:Continuously working time(When this function is available).
Fault Code Solution
1. When the display appears the fault code except for E7, after
solving the problems, there are two methods to remove the fault
co de。
①Press ON/ OFF button to restart for two times, then fault code
can be removed
②Remove and install the battery or turn off and open the water
tap.
2. When the display appears the fault code E7,or the display appe
ars other fault codes for 5 times in 15 minutes, display appear fa
ult code and “nL ,”the only solution is to press DOWN button for
more than 5 seconds. Then the fault code can be removed。
