1.1 Outdoor rainproof installation

The tankless gas water heater is installed outdoor, takes the combustion air from outdoors , exhausts the waste gas to outdoor. Users can operate the gas tankless hot water heater with wired controller, improving the safety of use.

1.2 Easy operation

Adopt an advanced smart microcomputer-controlled electronic proportional valve, an electronic gas regulator, a continuously variable DC blower and a high-load burner. To obtain the flow of hot water, switch on the power supply, press the power button and turn on the hot-water tap. The whole process is automatically controlled so that the operation is easy.

1.3 Easy adjustment of water temperature

The microcomputer calculates the required amount of gas and combustion air in accordance with the water flow, water inlet and outlet temperatures and temperature setting detected by sensors. An actuator in the water heater is triggered to increase the water temperature to the temperature setting. Achieve the thermostatic control with electronic proportional valve, provide a wide range and easy adjustment of water temperature and meet the user’s demand for great temperature adjustment around the year.

1.4 Detachable water filter

Considering the water quality in different areas, a detachable water filter is mounted at the water inlet to prevent any foreign matter from the water pipe and guarantee the normal running of water heater.

1.5 Low-pressure start

A low-pressure starter is used. It can detect the super-low water pressure with magnetic flow sensor and is suitable for areas under a low water pressure or high-rise residences.

1.6 Delayed ignition design

The unique delayed ignition function guarantees a higher rate of successful ignition and a lower ignition noise.

1.7 Automatic flow control

For great difference in water temperature between summer and winter, the water heater is configured with an automatic flow control device in order to meet the user’s demand for water temperature.

1.8 Volume setting of water to be filled into a bathtub

If a bathtub is used, a user can set the volume of water to be filled with the volume setting switch. When the water heater detects that the actual flow reaches the setting, a buzzer sounds to prompt the user to turn off the tap and stop the flow.

1.9 Remote controller

An advanced remote control system can be connected with an optional wired bathroom controller. The wired controller can be mounted far away from the location of water heater (connecting at most three wired controllers, length of connecting wire up to 30m). Furthermore, remote controllers can switch over for priority control. And the use of double nonpolar carrier communication design keeps the communication smooth.

1.10 Automatic diagnostics

The microcomputer diagnoses as programmed the operating state of control circuit, various safety devices, fans, proportional valve and other actuators in the running water heater. Stop the water heater and flash the error code on the displayer of wired controller if any error is found.

1.11 Safety protection against sudden power interruption or voltage drop

If the supply voltage drops suddenly or the power supply interrupts, the water heater will continue operating normally or stop safely.

1.12 Multiple safety protections for safer use

• An automatic flame-out safety device will shut off the gas supply in case of accidental flame-out. It prevents the gas leakage and operates safely and reliably.
• Timeout safety device

    Cut off the gas supply automatically and switch off the burner if the water heater has been running for 60±3 minutes. If you want to continue running the water heater, turn off the hot water tap and then turn it on to ignite the burner again.

• The forced-air blast combustion is designed. Adopt a high-quality continuously variable DC blower to exhaust the fume for safety.
• Additionally our water heater is equipped with an overheating protection device, an overpressure relief device, a freezing protection device, a blower cut-off safety device, a water interruption protection device, a flue anti-blocking device and other safety devices to guarantee the running of water heater under normal operating conditions.
