condensation does not flow back.
The angle of the ventilation pipe
must be 90°, and its quantity
should be no more than 3 pieces.
Inside the ventilation pipe, the
upper hole of the smoke exhaust
(flue) duct from the back must
have more than 250 mm height.
The upper part of the ventilation
pipe must be accompanied with
the windproof cover to prevent
wind and rain. The distance may
not be more than 600 mm from
the surrounding buildings.
Do not install the ventilation pipe
in the air replacement part or

connects the gas inlet pipe to the water
heater is G1/2.
Connecting to the LPG Tank
Install the connector in the package
to the gas inlet valve on the water
heater (make sure the seal has
been installed). Then, connect it to
the hose for gas (rubber hose) with
a diameter of 9.5 mm as shown in
the picture.
Make sure to use the gas regulator
with the right pressure (the exact
gas pressure standard is 2800 Pa
for LPG, 2000 Pa for natural gas).
Connecting to the Gas Pipe
It must use the gas hose or standard metal pipe.
Gas valve must be installed at the gas inlet pipe.

Valve Installation
Valve must be installed at the gas inlet pipe, water inlet pipe, and
water outlet pipe. After the installation, checking must be done to
make sure that there is no gas or water leak.

Preparation
1. Insert 2 pieces of battery. Make sure the positive and negative poles
of the battery are well-installed (not reversed).
2. Open the gas inlet and water inlet valves.
Turning On the Water Heater
When the water pressure is above 0.015 MPa, the water heater will be
turned on automatically if the hot water valve is opened. For the water
heater that is just installed, the gas pipe perhaps is filled with air and
cannot be turned on at the first time. Repeat the on and off process to
exhaust the air out until the water heater turns on.

Temperature Control
1. Adjust the water and gas controller knobs until the desired hot
water temperature is reached.
2. If the water inlet valve is installed, cold water valve may not be
rotated excessively, to prevent the reduction of the pressure (as a
cause of the pipe and the valve diameters difference) that affects
the normal operation of the water heater.
3. At certain places, the water pressure maybe too strong and thus
the water cannot be heated. In this case, please turn the water
inlet valve down (as shown in the illustration picture below).
4. Flame can be adjusted by turning the flame controller knob to the
‘ max’ or ‘ min’ position (refer to the illustration picture below).
