FUNCTION
1. Convenient
This water heater needs two A1 batteries to feed micro-computer(IC) power. You only need to
turn on the power button, open the gas valve, cold water valve and hot water valve; warm water
will be supplied continuously after several seconds. Whichever you turn off cold water valve, hot
water valve or the power button the water heater will stop working.
2. Gas saving
Advanced combustion system is used in the heater; the subsection switch device is designed for
winter & summer type.
3. Dry burning proof protection
It immediately closes the gas valve when there is no water flow.
4. 20 minutes timing protection
After working for 20±3min, the heater will stop for self protection automatically. When user wants
to go on using the heater, restarting it is enough.
5. Over-pressure protection
When water pressure is too high, it will unload automatically to avoid heater damage.
6、Hot water temperature display light(display light model)
While working the display light can shine.
7、Hot water temperature display (LED model)
While working the LED display window can show the hot water temperature.
