water heater will be turned off automatically after 20 minutes operating continuously. In this case,
close the hot water valve, and open it
again.
When the water pressure is above
0.025Mpa, the valve will be executed
automatically when opening the hot
water valve. For the water heater that is
just installed, the gas pipe perhaps is
filled with air and can not be turned on
at the first time. Repeat the on and off
to throw the air until the water heater
turns on.
