NOTICE
Reduce The Chance of Getting Furred
After shower, please turn off the gas valve and drain out the hot water in the water heater
until cool water is out. Then turn off the water inlet valve.
Freezing Prevention
Under the circumstance of low temperature, please drain the water remaining in the
heater completely after each use. Otherwise the water may freeze and cause damage the
heater.
The following phenomenon are normal:
When the water pressure is lower than 3psi, the heater cannot be ignited.
The drain valve is dripping. When the water pressure is too high, the drain valve will
release water so as to reduce the pressure to protect the heater.
When the heater is supplying hot water to too many points at the same time, the hot
water flow would be reduced, and under exceptional circumstances no hot water will
come out at all.
The gas water is for point of use, for temporary water heating and not for connection to a
permanent inlet water connection or for connection to a water distribution system to
supply multiple outlets.

Turn on the gas inlet valve.
Turn on the water valve (make sure there is water flowing out of the shower), and
then the water heater with “clicking” ignition sound. The burner is ignited and hot
water flows out instantly. If the water pressure is too low, or the power is not
connected, the water heater will not operate normally.
Check whether there is anything on the exhaust port. If yes, clean it.
After initial installation or change of gas cylinder, air may remain in the gas pipe
and it requires several ignition attempts to push the air out before the gas can be
ignited. If a problem comes up after normal operation, turn off the water
immediately. Try to re-ignite 10-20 seconds later to avoid blast burning.
Water Temperature Control
⑴Turn the water temperature regulator knob to control the water flow and its
temperature. Turn the gas regulator knob to control the flame of the burner thus
controlling the hot water temperature. (Fig. 16)

flow to make the water temperature higher (Please adjust it slowly, if the flame
extinguished then re-ignite before increasing the water flow), and increasing the water
flow to make the water temperature lower.
Turn off the hot-water outlet valve and the water heater will stop working
automatically, re-start hot water valve, heater will be re-ignite automatically and
start working.
Test water temperature with your hand before shower, so as to avoid
scalding.(Fig.17)
When the water pressure is too low, it’s suggest to turn the water flow control
