Special Advice:
When the water heater is working, gas combustion would consume a large amount of oxygen and exhaust much carbon monoxide. In view of the
great harm to the human health or even death caused by excessive carbon monoxide inhalation, the company sincerely advises all users that:
Do not install the water heater in the bathroom;
Install and use the water heater strictly in accordance with the requirements stipulated in the instructions; install a smoke pipe to exhaust
waste gases to the outdoor;
Make sure the room installed with the water heater has enough fresh air and is well-ventilated.

1. Water Control Automatic Ignition:
Simply open the water valve and
the igniter will ignite automatically with the hot water immediately
available.
2. Water Temperature Regulation:
Regulate the water temperature at
any temperature.
3. Flue-type Exhaust Device:
Exhaust waste gases outside to maintain
the indoor air fresh.
4. Season Change:
The model with a season change knob can
increase the adjustable outlet water temperature range by operating
the season change knob, thus saving gas in summer.
5. Low Water Pressure Start-up:
Low start-up water pressure with a
broad scope of application.
6. Steady Water Volume:
Effectively avoid the impact of water pressure
fluctuation on the water volume and the outlet water temperature; and
prevent the outlet water not hot due to too high water pressure.
7. Flame-out Protection:
The water heater will automatically cut off the
gas to ensure the gas not leaked when it flames out accidentally
during the use.
8. Water-gas Linkage Control:
The water heater will automatically stop
combustion and shut down when the supply of tap water is suspended
or the water valve is shut off.
9. Over-pressure Protection:
When the pressure of the water supply is
too high, the safety valve of the water heater can automatically relieve
pressure to avoid any damage to the water heater.
10. Anti-freezing Protection:
When the water heater is used in cold
areas where the outdoor temperature is below 0 °C, the anti-freezing
drain valve is set to drain the water from the water heater to avoid any
damage to the water heater caused by the water freezing in the water
heater.
11. Thermal Protection:
The water heater will automatically cut off the
gas and stop working when the temperature of the water flowing out
from the water heater exceeds 90 °C or dry burning occurs.
12. 20-minute Timing Protection:
The water heater will automatically
cut off the gas and power off after a 20-minute continuous operation.
The water heater can continue working only after a restart.
*13. Outlet Water Temperature Display:
A specific outlet water
temperature display function.
14. High Energy Efficiency Grade:
The energy efficiency grade conforms
to the requirements of the National Standards on Energy Efficiency
(GB20665-2006). The thermal efficiency of grade2 energy efficiency is
>88% and that of grade 3 >84%. See the energy efficiency label on the
front side of the water heater.
