Installation Requirement
1. Do not install the water heater in a bedroom, basement, bathroom, or any room with poor
ventilation. In order to keep the room for installation ventilated well, an air-intake (inlet) hole should
be made in the lower area of the room, and the area around the hole should not be less than 100
cm2.
2. The flame observation window of the water heater should be located in a position it can be easily
viewed (approximately 150 cm above the floor).
3. No cords or electric equipment shall be put above the water heater. The water heater should be
kept at least 40 cm away from the electronics horizontally. The water heater should be kept well
away from any flammable substance or liquid.
4. Do not install the water heater where adverse winds may blow, causing flame-out or incomplete
combustion.
Indoor Installation Position
Note:
The positions of the water inlet, water outlet, and gas pipe must be in accordance with the marks
on the water heater body.
Check carefully after the installation has done; make sure that there is no gas or water leak.
The maximum length of the rubber hose is 2 meters.
Cable, hose, and pipe are prohibited to pass the side or the upper of the water heater body.
The installation of the hanger must be horizontal.
Part 2: Installation

Hanger Installation
If the wall is not heat-resistant, it is recommended to coat it
with a heat-resistant board that is 100 mm bigger than the
water heater of every side and 10 mm from the wall.
Water Heater Hanger
The water heater should be hanged vertically. The
standard height of the water heater is adjusted with the
parallel position of the flame observation window
(peeping hole) to the human eyes.
Ventilation Pipe Installation
The water heater must have ventilation pipe. The installation of the ventilation pipe must be in
accordance with follow:
a. The height of the ventilation pipe must be in accordance so
that it can be drained the smoke out.
b. The horizontal part of this ventilation pipe must be less than
3 m, and the pipe must be a bit tilted down (±1°), so that the
water condensation does not flow back.
c. Angle of the ventilation pipe must be 90°, and its quantity
should be no more than 3 pieces.
d. The inside part of the ventilation pipe, above the hole of the
smoke exhaust (flue) duct from the back must be more than
250 mm.
e. 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.
f. Do not install the ventilation pipe in the air replacement part
or smoke ventilation track.
g. Make sure there is no air leak at the pipe connections,
fasten it with strong screws.

7
How to Install Ventilation
a. The air hole must be on the good ventilating position and 1/2 under the height of the room.
b. The pipe hole must be made outside and close from the upper part of the room, far from the
ventilation pipe.

Gas Pipe Installation
The diameter of the threaded bolt that connects the gas inlet pipe to
the water heater is G1/2.
Connecting to the LPG Cylinder
a) 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.
b) 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
a) It must use the gas hose or standard metal pipe.
b) 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.

2. Open the gas 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 throw 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).
Flame can be adjusted by turning the flame controller knob to the ‘max’ or ‘min’ position (refer to the
illustration picture below).
Turning Off the Water Heater
To turn the water heater off, switch off the hot water outlet valve or the water inlet valve. Then, the
flame will automatically extinguish, and the water heater will return to stand-by mode.
Note: The water heater cannot be used continuously for a long time. It will automatically turn off after
20 minutes continuous operation to prevent the accidental carbon monoxide poisoning due to
inadvertent or accidental long period use.

This gas instant water heater must be checked by professionals every 6-12 months, other things
that need to be checked are in the following bellow :
1.Seal of the gas and water track system.
2.Clean the filter at the edge of the water supply line to prevent congestion.
3.Functions of all the operating parts.
4.Burner of the flame.
5.Carbon crust cleaning for the heat exchanger.
6.Air loading and releasing system inside of the room where the water heater is installed.
7.Gas pressure reducer.
Must be checked by professional:
1.Flexibility of the water and gas piping connection.
2.Clean the carbon accumulation on the buckled part of the heat exchanger.
3.Apply the lubricants to the gas valve and on its middle part.
4.The disturbing carbon accumulation and oxidation layer.
Maintenance of the water heater by the user:
1.Clean off the dirt and dust accumulation on the surface of the water heater with the fabric
regularly. Do not use that chemical that can change the color of the surface.
2.Clean off the dust and the carbon accumulation inside of the ventilation pipe and the heat
exchange regularly for making sure the smoke track flow smoothly.
Note: Remove the ventilation pipe; clean the heat exchanger part with a soft brush. During the
process, do not let the dirt and dust enter through the fire hole of the burner and also from the part of
electric tools. Do not eliminate or damage the tools. When re-install the ventilation pipe after cleaning,
make sure to fasten all part of the connector.
Problem
Possible Cause
Recommended Actions
Over-high water pressure.
If the water pressure exceeds 0.5
MPa, the water outlet valve will
release the water and lower the
water pressure.
Increase the limit of the
valve pressure in
accordance with the local
water supply pressure.
The water heater automatically
shut off after 20 minutes
continuous operation.
After it has been used for 20
minutes, the water heater will shut
off automatically
Turn on the water heater
again after 5 seconds.
Over-low Water pressure.
If the water pressure is under
0.015 MPa, the water heater
cannot be turned on.
Use the water heater after
the pressure is higher.
Low battery.
The battery power will reduce after
some time of usage, so that the
water heater cannot be turned on.
Change the battery.
Excessive heat protection.
Water heater will turn off
automatically when the
temperature is above 77o C.
Turn on the water heater
again after the water
becomes cold.
