to select qualified gas pipe, pressure regulating valve, steel
cylinder, clamp, smoke exhaust pipe and so on. You must
entrust a qualified and specialized technician to install the
gas water heater. (Note: The user cannot install the gas
water heater himself/herself, since an improper installation
can bring a great impact on the safety performance, or even
threaten the user’s life.) Prior to the installation, please
reconfirm whether the type of gas you are using agrees with
the type of gas specified on the rating plate of the water
heater.
This water heater is a flue gas water heater, which can be
used only after all exhaust gases vented to the outdoors in
strict accordance with the requirements. It is forbidden to
use this water heater if the smoke exhaust pipe fails to be
correctly installed according to the requirements in this
manual.
Since each user has his/her own building structure, this
company cannot provide a uniform smoke exhaust pipe. The
user can purchase his/her proper smoke exhaust pipe based
on his/her own building structure.
Installation Requirements
1. Do not install the water heater in bathrooms;
2. Do not install the water heater in a place where there is
strong wind, otherwise the flame of the water heater will
be blown out or an incomplete combustion will occur.
3. Do not install the water heater in the outdoors.
4. Do not install the water heater in a confined room. Install
it in a well-ventilated room with a volume more than
7.5 m³. There should be an air inlet with an area more
than 0.06㎡connected to the outdoors. A smoke exhaust
pipe must be also installed.
5. Install the water heater in a place where the line of sight
and the viewport are at the same level, that is,
1.55~1.65m above the ground, and where the water
heater is distant from combustibles.
6. Do not place any electric open wire, electric appliance or
gas pipeline above the installation site of the water
heater. Keep a horizontal distance more than 40cm
between the water heater and electric appliances. Do
not install any gas appliance such as the gas oven and
the gas range underneath the water heater.
7. Keep a distance greater than 150mm between the water
heater and the surrounding walls and the ceiling. Build
the installation site with noncombustible materials.
Otherwise, insulate the water heater with a heat
insulating panel. The distance between the insulating
panel and the surrounding walls should be greater than
10mm.
8. Install an inlet valve in the water inlet pipe of the water
heater.
9. Place the vent of the smoke exhaust pipe in the outdoors.
10. For liquefied petroleum gas users, select qualified gas
pressure regulating valves and hoses to ensure the
water heater a proper operation and security use; for
pipeline gas users, ask the gas company or the relevant
management authority to connect gas pipes.
After the flue gas water heater is installed with a smoke
exhaust pipe, during the use, do not turn on any

Installation Modes
1. Keep the water heater vertical and not inclined during
the installation. As shown in the right diagram, drill
installation holes on the wall. Knock the expansion
screws into the installation holes on the top for fixing,
and insert the plastic plugs into the installation holes at
the bottom. After mounting the water heater, place the
gaskets and nuts into the expansion screws and screw
up the nuts. Screw on the tapping screw at the bottom.
The user can choose any installation mode from A and B
installation modes according to the actual situation of
each model.
2. Cautions for the Installation of the Smoke Exhaust Pipe:
a. The water heater must be installed with a smoke exhaust
pipe during the use. For the dimensions of the smoke
exhaust pipe, see the Technical Performance Parameter
List. The pipe should be installed according to the
requirements in this manual.
b. Determine the length of the corrugated tube as needed,
but the total height of the tube should be greater than
2m, the horizontal length no more than 3m, the elbows
no more than 2 and the angles no less than 90° so as to
reduce the smoke exhaust resistance.
c. Fasten the corrugated tube and the smoke vent of the
water heater with clamps to prevent exhaust gases
being vented to the indoors.
d. Make the flue pipe inclined 3° outward and downward to
facilitate the outflow of condensate water.
e. Blanket the flue pipe with heat-insulating and fire
retardant materials whose thickness must be greater
than 20mm when the flue pipe passes through the wall
made up of combustible materials.
f. Try not to hide the flue pipe inside the ceiling. Wrap up
the flue pipe with heat-insulating materials whose
thickness is greater than 20mm if it is inevitable. Keep a
distance greater than 150mm between the flue pipe and
the combustibles such as the ceiling and the furniture.
g. For maintenance, do not use cement to fill the clearance
between the flue pipe and the round hole on the wall
through which the flue pipe threads.
3. Installation of the Smoke Exhaust Pipe
a. Open a hole with its diameter slightly greater than that of
the smoke exhaust pipe in place near the water heater to
easily put the horizontal smoke exhaust pipe through the
hole. Extend the smoke exhaust pipe outside the room
and make the outdoor terminal slightly inclined
downward.
b. Set the air vent at a higher position with its minimum
height no less than the height of the water heater.
c. Set the air intake at a lower position to prevent the
outdoor air from directly entering the combustion
chamber.
d. Install a wind resistant cap firmly.
Note: It is absolutely forbidden to use this water heater
with no smoke exhaust pipe installed.

4. Installation of the Gas Pipe
a. Select specified rubber hoses or qualified rigid pipes
and gas pressure relief valve. (GB10546 and GB12244
compliant).
b. Select the dimensions of the pipe according to the
Connector Specifications in the Technical Performance
Parameter List.
c. The length of the rubber hoses cannot be greater than
2m when the liquefied gas is used.
d. Install a rubber seal ring between the gas intake of the
water heater and the hose connector. The rubber hose
must be connected to the red line of the hose
connector and must be fastened with a clamp.
e. Connect with a rigid pipe when the pipeline gas is used.
Install a gas valve, the passage of which has an
effective area greater than 45mm2, that is, the inner
diameter is more than Φ7.5mm.
f. After the installation, use the soapy water to check
whether there is a gas leak.
Using Methods
Preparations before Ignition
1. During the initial use of the water heater, open the
battery case and put in two D batteries according to the
correct battery polarity.
2. Switch the water inlet valve to the maximum and switch
on the hot water outlet valve to check whether there is
water flowing out.
3. Then, switch off the hot water outlet valve and fully
open the main gas valve.
Ignition/Operation
1. Ignition: After the preparation work, open the hot water
outlet valve, and the water heater will make a “poop”
sound, and then the hot water will immediately flow out.
If the water heater cannot be ignited for one time,
switch off the hot water outlet valve at once and restart
it after 10-20 seconds. (Note: For some models, adjust
the Hot/Cold Water switch to the hot water mode
before ignition.)
2. Outlet water temperature regulation: Switch the
firepower regulation knob to “Max” or switch the water
temperature regulation knob to “High”, the outlet water
temperature can be increased; switch the firepower
regulation knob to “Min” or switch the water
temperature regulation knob to “Low”, the outlet water
temperature can be decreased.
3. When the firepower regulation knob is switched to
“Min” and the water temperature regulation knob is
switched to “Low”, if the outlet temperature is still high,
then switch the season change knob to the
“Summer-Autumn” position. On the contrary, when the
firepower regulation knob is switched to “Max” and the
water temperature regulation knob is switched to
“High”, if the outlet temperature is still low, then switch
the season change knob to the “Winter-Spring”
position.

Discontinuing
1. Switch off the hot water outlet valve and the water
heater will automatically shut down.
2. Switch off the water inlet valve.
3. Switch off the main gas valve.
Replacing Batteries
1. If the time interval of the “poop” sound during ignition
is a little long (twice a second), or the fire is soon
extinguished after ignition, change the batteries
immediately.
2. Use sealed damp-proof iron clad batteries. Normally,
change the batteries every half a year.
Caution:
Prevention of Gas Accident
1. Determine the type of gas. Make sure the type of gas
you are using agrees with the type of gas specified in
the rating plate of the water heater. Do not
disassemble the water heater without authorization
and use a different type of gas by force.
2. Check whether the combustor is extinguished after
the use and remember to shut off the main gas valve.
3. Frequently check whether there is a gas leak in the
connectors and the gas line. Normally, change the
rubber hoses once a year.
4. For LP gas users, if the flame of the water heater is
detected floating, the pressure relief valve connected
to the vent of the gas cylinder may fail to work
properly. Then stop using the pressure relief valve
and replace a qualified one instead.
5. For pipeline gas users or natural gas users, if the gas
flame is detected abnormal (caused by unstable
pipeline gas pressure), suspend using the water
heater. The forced use may damage the water heater
or even cause an accident.
6. If a gas leak is detected, do not ignite the water heater
or switch on any electrical appliance. Open all doors
and windows to automatically vent the gas to the
outdoors. Stop using the water heater and contact the
maintenance department or the gas company.
7. It is forbidden to operate the water heater with any
failure. Contact our maintenance department timely
once any failure occurs.
8. This water heater is only used for the hot water supply
and shower. Do not use it for any other purpose.
Warning: This Company will be not liable for any
accidents caused by unauthorized dismantling of this
water heater or failure to comply with the installation
and operating instructions outlined in this manual.
Special Attention: When the hot water is used again
after suspended for a while, do not wash your body
with the hot water at the very beginning. That is
because when the hot water is suspended for a while,
the water temperature of the water heater will become
very high. The hot water can be used only a few
seconds after the hot water flows out to avoid scalding.

Prevention of Fire
1. Absolutely do not go out or go to bed with the water
heater on.
2. Do not place any combustibles near the draft hood of
the water heater. Do not use towel, clothes and other
things to cover the vent.
Prevention of Carbon Monoxide Poison
1. A large amount of oxygen is needed when the water
heater is used. Therefore, the site where the water
heater is installed must have enough air for
supplement and be well-ventilated. The room where
the water heater is installed must have a fixed open
air intake. The closed doors and windows cannot be
classified as effective air intakes.
2. A large amount of exhaust gases will be vented when
the water heater is used. Therefore, the water heater
must be installed with a smoke exhaust pipe to vent
the exhaust gases produced during burning to the
outdoors.
3. When the manufactured gases or natural gases are
used, if the gas supply pressure is too low, there may
result in tempering, hence affecting the normal
operation of the water heater. At this point, the flame
will turn from blue to yellow and the discharge of
Carbon Monoxide will increase significantly. Stop
using the water heater at once.
Other cautions:
1. Non-potable: Since there is water stored in the water
heater for a long time, the hot water provided by the
water heater is not potable, just used as non-potable
water.
2. Freezing prevention: When the water heater is used
in cold areas where the ambient temperature is below
0
°C , the water stored in the water heater must be
drained to prevent the water heater is damaged,
since the water will expand when it freezes. The
water can be drained as follows:
a. Switch the water temperature regulation knob to
“Low” after shutting off the water inlet valve.
b. Switch on the hot water outlet valve.
c. Screw off the drain valve. After draining the water,
screw on it and shut off the hot water outlet valve.
Since there is a rubber gasket in the drain valve,
screw it with great force.
3. During ignition, it is strictly forbidden to observe the
ignition with the eyes closely near the viewport. The
distance between the eyes and the viewport should
be at least 300mm.
4. When the water heater is not used for a long period of
time, take the dry batteries out from the battery case
to prevent the battery case from corrosion due to the
damage to the batteries, hence leading to poor
contact and affecting the use of the water heater.
There must be a
fixed open air intake.

Treatment of Abnormalities
When abnormalities are detected such as a gas leak,
abnormal combustion (such as tempering, flame lifting,
yellow smoke or black smoke emission), peculiar smell and
abnormal sound, or other emergent situations, immediately
shut off the gas valve and contact the maintenance
department or the gas company for treatment.
Maintenance
1. Frequently check whether the Gas Intake Pipe (rubber
hose) is in good condition and whether there is aging or
any flaw. Regularly change the rubber hose and
frequently use the soapy water to determine whether
there is a gas leak by checking whether there are
bubbles at the pipeline connectors.
2. After the water heater is used for a period of time
(generally about half a year), it is necessary to check
and clean the water heater to ensure it operating
normally. Frequently observe the burning conditions of
the flame. When the flame turns form blue to yellow
and there arises black smoke, contact the technician in
time for cleaning.
3. Frequently use soft cleaning cloth to wipe the hull of the
water heater with clean water or neutral detergent
rather than chemical detergent or volatile solvent.
Otherwise, the color of the hull will fade away and
tarnish.
4. Regularly clean the water intake filter of the water
heater.
5. When the water heater is not used for a long period of
time, screw off the drain valve and drain the excess
water in the water heater to avoid any damage to the
water heater according to the Other Cautions.
Repairing Services
1. The water heater must be regularly checked and
cleaned by the professional personnel.
2. Non-professional personnel cannot open the front
cover of the water heater.

Troubleshooting
The following phenomena are not failures:
The vent gives off
white smoke
The hot water becomes cold
because of low flow.
In winter, the
high-temperature water
cannot flow out.
In summer, the
low-temperature water
cannot flow out.
The water heater flames out
suddenly after being used for
20min.
Problem Root Causes and Corrective Actions
Problem Root Causes and Corrective Actions
The room temperature is too low, so the exhaust gas is condensed into white fog when
meeting the outdoor cold air.
When the hot water is in low flow (below the start-up water pressure), the water heater
blows out and hot water becomes cold. Therefore, do not leave the hot water in low flow.
When the supply water temperature is too low and the water volume control knob is
switched to the large mode, the heating capacity of the water heater may be insufficient.
At this point, please switch the season change knob to the “Winter-Spring” mode or lower
the water flow appropriately.
When the supply water temperature is too high, the temperature is set low and the hot
water faucet is turned down, the outlet hot water temperature may be too high. At this
point, please switch the season change knob to the “Summer-Autumn” mode or increase
the water flow appropriately.
In case of the lack of oxygen, some models have the 20-minute timing protection function, that
is, after a 20-minute continuous use of the water heater, the water heater will automatically
extinguish. Please turn off the hot water faucet and use the water heater after a while.
