Special Advice Read the technical instructions before installing the appliance. Read the user’s instructions before lighting the appliance. The manufacturer or any danger resulted from installation and operations not bear responsibility for any danger resulted from installation and operations not in accordance to this manual. When the outdoors temperature is less than 0℃, the residual water inside the heater must be drained after use. Features & Benefits Micro‐Computer Intelligent Control System The core component of the gas water heater is micro‐computer intelligent control system, which is one of today’s most advanced mechatronic technology. The CPU chipset can analyze automatically and set the optimal working parameter rapidly according to different data such as the flowing water quantity, the pressure situation and the actual inlet water temperature. Digital Control for Automatic Constant Temperature of Outlet Water This function is to monitor the outlet water temperature by a temperature sensor and to transfer the information to the micro‐computer, so that the micro‐computer could adjust the gas and air supply quantity to guarantee the constant outlet water temperature according to the temperature set by the user and the actual inlet water temperature automatically. ... - Page 4 Set Temperature by Touch You could set the required temperature easily by touching the digital display. The setting temperature is from 35℃ to 65℃, which can meet different water temperature requirements with easy operation. Multiple Safety Protection This product has safety protections includes self‐check protection, flame‐out protection, over‐heat protection, accidental power‐cut protection, fan breakdown protection, over electric load ...

- Page 11 • Gas inlet (1) Before connecting the gas supply, check the rating plate on the left 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. (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. ...

Installation of the flue: • Flue Duct Installation of Forced‐Exhausted Gas Water Heater (B type) This product is forced exhaust type gas water heater; it can be used only after the flue duct is installed according to the requirements strictly and can exhaust the waste gas to the outdoor area. It’s not allowed to use the gas water heater without installing the flue duct correctly. Please follow the below requirements during the installation of flue duct: (1) Please use the flue supplied by our company, referring to Fig. 11 about the installation method. If the flue duct is too short, you can extend it aptly. Check the flue duct and see if there ...
- Page 13 (1) Please use the flue supplied by our company, referring to Fig. 11 about the installation method. If the flue duct is too short, you can extend it aptly. Check the flue duct and see if there is any damage or leakage every half a year. 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 2°downward inclination (Fig. 11), otherwise the rain may flow into the heater and damage it. (2) The length of the flue duct should be less than 3m, and the number of elbows should not be more than 3 ( one elbow equivalent 1m straight pipe). (3) The distance between the flue duct and the combustible materials should be more than 150mm. If the flue duct needs to get through the combustible materials or wall, it should use the ...

6. Inquiry the cumulative amount of gas and water In working statement, @ buttons can inquire about the cumulative water consumption and gas consumption. Click the @ key to query cumulative amount of using water information, press @ key again can be inquired accumulated gas consumption information. Press the third time for the @ button or no operation for 20s, can exit the inquiry function. Note: • Real‐time gas consumption show the basic unit of m³/h • Real‐time hot water production show the basic unit of L/min • Cumulative amount of using water and gas consumption show the basic unit of m³, When the display numbers reach 999m³,water record is automatically cleared. For example, when the query information display "Water production 180m³", represents a total cumulative amount of water heater 180m³. When real‐time gas consumption information shows "volume 8.3m³", it indicates the water heater cumulative total gas consumption 8.3m³. ... - Page 18 • Close down the cold water valve sans 3, if a valve is installed on the hot water circuit, open it. • If there is a control valve 4 at the hot water outlet, please open it. • Turn the drain valve 5 and take off, replace it after the residual water is completely discharged. Fig.14 ...
- Page 19 ■ Gas accident prevention • Check if the flame of burner is out after use and do not forget to turn off 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 flame or electric spark can result in explosive accidents. (Fig. 16) • 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. ...
- Page 20 ■ Carbon Monoxide toxicosis prevention • This product must exhaust the waste gas to the outdoor area during working, so the flue 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 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. Therfore, 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. ...

Page 21: Maintenance
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, 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. ... -
