Installation
Contact your local gas dealers or gas management department for a qualified engineer to install the gas
water heater (users are recommended not to install by themselves).
■Installation place
●The flue of the gas water heater should be installed through an external wall, the heater cannot be
installed in outdoors. (Fig.3)
The flue of the heater cannot be connected to a common flue (Fig. 4).
●Please don’t install the heater in places where special chemicals are used, such as the laundries or
factories etc., otherwise it may cause rusting, shorten the lifetime of the heater, or prevent normal
working.(Fig. 5)
●Do not to install the flue of the heater through the wall whose window can be opened because the
waste gases may flow back into indoors if the window is opened during using operation.(Fig. 6)
●Don’t install the heater above the gas stoves or other heat sources. (Fig. 7.)
●The power of the heater is 230V, 50Hz/AC, the power socket must have a reliable ground wire,
preferably with a switch. If there is a water leakage near the power cord, move it to a suitable place.
(Fig. 8)
■Installation methods
Drill holes in the wall according to the dimension of Fig.2, fix with expansion bolts in the upper hole and
fit the lower hole with plastic cock, hang up the heater and use a self-tapping screw fix for the lower
hole of the heater.

- 7 -
The height is suitable when the flame check window is at eye level (1.5～1.65m above the ground) (Fig.
10)
No visible electric wires or electric appliances are permissible above the heater, the horizontal distance
between the heater and the electric appliance should be more than 400mm. The distance between the
heater and the wall should not be less than 150mm, and the flameproof board should be 100mm bigger
than the heater. (Fig. 11.)
■Installation of the flue:
●This product is a Forced Exhaust and supply gas water heater, it can be used before exhausting the waste
gas to the outdoor according to the strictest requirements. It’s not allowed to use the gas water heater
without operating the flue correctly.
Installation position of flue terminal protruding through wall. The minimum flue length is 650mm, and
the maximum flue length is 3000mm with one elbow. (Fig. 12)
Install the flue after the heater body is fixed. First, put the fixed flue through the hole in the wall, then
insert the elbow into the exhaust outlet of the heater smoothly, the flue end should have a 20 downward
inclination (Fig. 11), otherwise the rain may flow into the heater and damage it.
Use concrete to seal the gap between the flue and the wall. If the flue is installed through the glass, use
the glass glue to seal the gap tightly.
Cautions for flue installation

- 8 -
Please use the flue supplied by our company, Other flues with different specifications are strictly
prohibited. Do not change the specification of the flue.
The installation of the flue must be correct, otherwise the waste gases will flow back and be
dangerous.( Fig. 14)
■Installation of water and gas pipes (Fig. 15)
●It can be used when the flue system can ensure that the provided gas pressure can reach the lowest
requirement. If gas water heater reaches the rated heat input, the gas pressure must reach the rated
heat input in the technologic parameter form.
●Gas inlet
(1) Before connecting the gas supply, check the rating plate on the right side of the right front cover to be sure
that the heater is rated for the same gas to which it will be connected.
(2) All such pipe shall be either new or previously used for no other purpose than conveying gas; and must be in
good condition and free from internal obstructions. Burred ends shall be reamed to the full bore of the pipe. All
fittings used shall be of malleable iron, yellow brass, or approved plastic fittings. And flexible tube is not
allowed.
(3) When your connections are made, check for gas leaks at all joints (this includes all existing piping). Apply
soapy water to all gas fittings and gas valve. Soap bubbles are a sign of a leak.
NOTE: No substance other than air, carbon dioxide or nitrogen can be introduced into the gas piping.
NOTE: If you have a leak, shut off the gas. After verifying the leak, tighten appropriate fittings to stop leak. Turn
the gas on and check again with a soapy solution. Never test for gas leaks using a match or flame.
●Cold water inlet
When facing the heater, the cold water inlet is on your right and the hot water outlet is on your left. Although
water piping throughout your structure may be other than copper, we recommend that copper piping be used for at
least 0.92 m before and after the heater (follow local codes). Keep water inlet pipe to no less than 1/2” diameter to
allow the full flow capacity.
Remember that water pressure must be sufficient to activate the heater when drawing hot water from the top floor.
If the hot and cold connections to the heater are reversed, the heater will not function. 1/2’’Copper or brass fittings
work best when connected to the connectors. The flexible type connectors will make instillation easier and seals to
the water valve by means of a union connection with a washer type gasket at the joint. No pipe dope or thread tape
is to be used at this joint. Be certain there are no loose particles or dirt in the piping. (Fig. 15)
Water pressure must be sufficient to activate the water heater, the maximum pressure for the appliance is 10bar,
even with the effects of water dilation, the water pressure in the appliance shall not exceed this value.

- 9 -
●Hot water outlet
Use a flexible or rigid pipe to connect with the sprayer without valve. If a valve or switch is connected to
the sprayer, the outlet pipe shall not use heat and pressure unendurable material such as plastics,
aluminum pipes, so as to avoid the pipe from breaking and scalding the user.

Using methods
FOR YOUR SAFETY READ BEFORE OPERATINGYOUR HOT WATER HEATER
WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing
property damage, personal injury or loss of life.
For type C
1. Preparation before ignition
●Make sure that the gas used is in accordance with the gas stipulated in the label.
●Insert the plug, and then switch on the power.
●Open the water valve, turn the water valve to get suitable water volume if necessary.

- 10 -
●Turn on the gas valve.
●Press the “on/off” key on the control panel, the screen display and the designed hot water temperature.
Press Up ▲or Down▼to set the hot water temperature as desired. The lowest hot water
temperature of this product is 35℃, highest is 65℃, minimum adjusting range is 1℃, the normal
shower water temperature is 40℃around.(Fig.16/ Fig.17)
2. Ignition and water outlet
●Open the water valve, the screen display the sprayer with water flowing out and running fan, then the
heater is ignited, a flame indicates on the screen, the water becomes hot, the screen indicates the hot
water temperature.
●If the heater has some trouble, the screen will display the trouble code, please close down the water
valve, then reopen it, or press the “on/off” key to “off”, then press it to “on”, if the heater still has
trouble, please close down the gas valve, switch off the power, ignites again after a while.
●Adjust the water volume and temperature according to need during the using process, as described
above.
●It might take several trial ignitions after installation or the first use after recharging the gas tank to
push out all the air remained in the gas pipe.
●When the valve is open, while the switch is in “off” position, the heater doesn’t work, only cold water
flows out, if hot water is needed, press the switch to “on” position.
●Close down the water valve, the heater stops working, but the fan will continue blowing the chamber
for several seconds. If you don’t turn off the power, then next time when you open the water valve,
the heater will work according to the water temperature set up previously.
●Every time when using, observe the temperature on the screen, use after the temperature is near the
setup value to avoid scalding.
●Turn off the gas valve and power after each use.
Prevention of freezing water
Drain the residual water inside the heater to prevent freezing water after every use when the environment
temperature is near or under 0℃, do as instructed (Fig. 18)
Close down the cold water valve ①, if a valve is installed on the hot water circuit, open it.
Turn the water temperature knob ②to “low” position, or turn the water volume button knob to “large”
position (level).
Turn the drain valve and take off, replace it after the residual water is completely discharged.
It’s not good to use the water heater for over 15 minutes in every continual use. If you would like to
continuing use for a long time, you must close it for 5 minutes after 15 minutes use, and then restart in
order to prolong the product’s life.

- 11 -
■CAUTIONS:
▲If you open the water valve first, and then open the power, the water heater will not start automatically.
▲When you shower, avoid immediately putting the water on your head and body in case of scalding. You
should use your hand to detect the water temperature before showering.
▲After using the high temperature water, because hot water is still in the pipe, please use your hand to
detect the temperature before your shower in case of scalding.
Cautions for safety
■Gas accident prevention
●Check if the flame of burner is out after use and do not forget to turn off the gas valve (Fig 19) and
power.
●Always check the gas connectors for gas leakage with soapsuds. If any gas leakage is detected, open
the room windows and doors. At that moment, do not ignite or operate the switch of electric
appliances or plugs because the flame or electric spark can result in explosive accidents. (Fig. 20)
●Heaters must use the gas type which the heater is designed to use, different type of gas or the same
gas in different place must not be used.
●Always check the gas pipe and change the pipe every year to avoid gas leakage due to cracking.
●If the flame goes unsteadily, stop using the water heater and contact the qualified service facility for
repair or adjustment.

- 12 -
■Fire prevention
●Do not leave the water heater unattended whilst still in operation.
●In case of power failure or water failure, turn off the gas valve and water inlet valve.
●Do not place towels or clothes on top of the water heater.(Fig. 21)
●Do not store inflammables, explosives or volatiles near the water heater. (Fig. 22)
●Never incline the gas tank or turn it upside down, the fluid gas is easy to flow into the heater and cause
fires.
■Carbon Monoxide toxicosis prevention
●This product is forcebly exhausts combustion and intakes the air needed for combustion through the
flue, so a flue must be installed in the outlet of the heater to completely discharge the combustion
bi-products to the outdoors and intake the combustion air from outdoors so as to keep the indoors air
fresh and prevent incomplete combustion. Otherwise, it will cause danger or even death.
●Too low or too high gas pressure leads to abnormal combustion. At that moment, stop using the water
heater and get in contact with a service engineer.
●Dust and accelerated carbon would block the heat exchanger due to long time use, and affect the
combustion performance, causing the Carbon monoxide to increase. Therefore, contact a qualified
person to clean and clear the dust and accelerated carbon every half year to ensure the combustion
product discharges smoothly.
●The heater must be installed vertically, if inclined it will make the flame touch the heat exchanger and
cause the monoxide to increase.
■Don’t drink the heater water

- 13 -
The water in the heater is not suitable for drinking.
WARNING: Forbid any interference with a sealed component, a fire or explosion may result causing
property damage, personal injury or loss of life.
■Handle with abnormal conditions
If there is abnormal burning (flame light-back, flame lift, yellow tip or black smoke, etc), smell or noise,
or other emergent situations, keep calm and shut off the gas supply valve and power switch, and contact
the service facility or gas dealers for repair or adjustment.
▲Scald prevention
●Do not look closely at the flame check window when igniting so as to avoid burning eyes. Keep 300mm
away.
When using the heater discontinuously, be careful not to be scalded by the over high temperature hot
water at the start and stop times.
During use and immediately after, do not touch any places especially the surround of the flame check
window or the front cover except for the knob and control panel in order to avoid scalding.
Maintenance
▲Always check the gas pipe for cracks.
▲Clean the filter in the water inlet faucet monthly.
▲Always check for leaking water.
▲Ask qualified technicians to examine the burner, flue and fan once a year.
▲Always check the flame inside the water heater for any abnormal conditions.
▲Keep the cover of the water heater clean.
▲This product uses water pressure to open the channels. When the water pressure is lower than 0.2bar, the
heater cannot be ignited.
▲The drain valve is dripping. When the water pressure is too high, the drain valve will release the water so
as to reduce the pressure to protect the heater.
▲When the heater is supplying hot water to several points at the same time, the hot water flow would be
reduced, or no hot water will issue at all.
▲When the temperature outside is too low and the exhausted gas meets the cold air, it will be condense as
white fog. This is normal.
▲When the water temperature is too high, set to a lower temperature and reduce the water tap. If the water
temperature outlet is too high, please open the tap to reduce the temperature.
▲When the water temperature is too low, and the hot water volume is so high so that it exceeds the
heater’s heating power, the outlet water will be not hot enough, please reduce the water volume.
▲In order to ignite immediately, the fan in the appliance will delay running for a long time and then stop
automatically. This is normal.
▲When you use the multi-function shower, the resistance may be too large, and the water inlet pressure
will be too low or the water inlet volume will be too little (below the starting –up water volume), there
may be flameout or can not be ignited, please choose the suitable shower function.

- 14 -
▲The residual water in the heater may be frozen in the winter, this is bad for the heater, so you must drain
the water after use. (Please refer to the drain methods.).
▲In order not to create scaling, please close the gas valve after using the heater, let the hot water out of the
appliance. When the outlet of the hot water is cold, close the cold water valve.
Cleaning: The water heater should be cleaned annually, keep the dust away from flue gas passageway. See
the Cleaning Instructions below.(Only for service engineer)
1).Turn off power, shutoff gas supply;
2).Wait one hour to cool down water heater;
3).Remove the front cover, by taking out Cover Screw;
4).Using compressed air or equivalent to clean the area between the fins and the heat exchanger;
5).Do not unscrew or move any other parts of water heater;
6).After Cleaning, put the front cover back.
