- Gas inlet

(1) Before connecng the gas supply, check the rang 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 obstrucons. Burred ends shall be reamed to the full bore of the pipe. All ngs used shall be of malleable iron, yellow brass, or approved plasc ngs. And exible tube is not allowed.
(3) When your conncons are made, check for gas leaks at all joints (this includes all existing piping). Apply soapy water to all gas tngs 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. Aer verifying the leak, ghten appropriate ngs to stop leak. Turn the gas on and check again with a soapy soluon. Never test for gas leaks using a match or ame.

- Cold water inlet

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 aer the heater (follow local codes). Keep water inlet pipe to no less than 1/2" diameter to allow the full ow capacity.
(2) Remember that water pressure must be sucient to acvate the heater when drawing hot water from the top oor. If the hot and cold connexons to the heater are reversed, the heater will not funcon. 1/2" Copper or brass ngs work best when connected to the connectors. The exible type connectors will make insllaon easier and seals to the water valve by means of a union connexon 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 parcles or dirt in the piping. (Fig. 10)
(3) Water pressure must be sucient to acvate the water heater, the maximum pressure for the appliance is 10bar, even with the eects of water dilaon, the water pressure in the appliance shall not exceed this value.

- Hot water outlet

Use a exible 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 plascs, aluminum pipes, so as to avoid the pipe from breaking and scalding the user.

■Gas accident prevenon
- Check if the ame of burner is out aer use and do not forget to turn o the gas valve (Fig. 15) 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 ame or electric spark can result in explosive accidents. (Fig. 16)
- Heaters must use the gas type which the heater is designed to use, dierent type of gas or the same gas in dierent 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 ame goes unsteadily, stop using the water heater and contact the qualified service facility for repair or adjustment.

off Turn off gas after use.

Acid Alkali flammable liquid

■ Carbon Monoxide toxicosis prevenon

• This product must exhaust the waste gas to the outdoor area during working, so the ue duct must be connected to the joint on the top of the water heater to exhaust the waste gas out to the outdoor area, keep the air fresh indoor and avoid incomplete combustor. Otherwise, it will cause danger or even death.
• Too low or too high gas pressure leads to abnormal combustor. 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 me use, and aect the combuston 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 combuston product discharges smoothly.
• The heater must be installed vertically, if inclined it will make the ame touch the heat exchanger and cause the monoxide to increase.
  ■Don't drink the heater water

The water in the heater is not suitable for drinking.

1. Handle with abnormal conditions

If there is abnormal burning (ame light-back, ame li, yellow p or black smoke, etc), smell or noise, or other emergent situaons, keep calm and shut o the gas supply valve and power switch, and contact the service facility or gas dealers for repair or adjustment.

■Scald prevenon

• When using the heater disconnuously, be careful not to be scalded by the over high temperature hot water at the start and stop mes.
• During use and immediately aer, do not touch any places especially the surround of the ame Check window or the front cover except for the knob and control panel in order to avoid scalding.

WARNING: Forbid any interference with a sealed component, a fire or explosion may result causing property damage, personal injury or loss of life.

Maintenance

▲ The appliances should be checked and maintained periodically by a competent person
▲Check the gas tube/pipe regularly for any defect. Contact service center for any doubt. Always check the gas pipe for cracks.

▲ Always check for leaking water.
▲ Ask qualified technicians to examine the burner, ue and fan once a year.
▲ Always check the ame 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 me, the hot water ow 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 heang 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 me and then stop automacally. This is normal.
When you use the mul-funcon 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 starng-up water volume), theremay be amout or can not be ignited, please choose the suitable shower funcon.
▲ The residual water in the heater may be frozen in the winter, this is bad for the heater, so you must drain the water aer use. (Please refer to the drain methods.).
▲ In order not to create scaling, please close the gas valve aer 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 ue gas passageway. See the Cleaning Instrucons below.(Only for service engineer)

1). Turn o power, shuto 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 ns and the heat exchanger;
5). Do not unscrew or move any other parts of water heater;
6). Aer Cleaning, put the front cover back.
