Special Advice Since the combustion of the gas will consume a large amount of air and produce Carbon Monoxide while the heater is working. However, if human inbreathe too much Carbon Monoxide, it will cause danger or even death .Therefore, the users are requested to install and use this heater strictly according to this manual to avoid Carbon Monoxide toxicosis. 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. Features & Benefits 1. Automatic operation Simply turn on the hot water tap or shower, and hot water will arrive. When the tap is turned off, the flame will automatically go out. Independent control of water flow and gas flow makes it easy to adjust the water temperature. 2. Innovative design Sleek shape and convenient to install. ...

Installation ●Before installation ,contact the qualified technicians in local gas dealer or gas management department to do the installation . Any random or improper installation will affect the safety use of the machine or even damage users life. ●If the flue type gas water heater install a flue , it is strictly prohibited to open the mechanical ventilation equipment like the cooker hood and ventilation fan in rooms that are installed or connected through when it is in operation. Installation requirements ●Do not install the water heater in bedroom , basement ,bathroom ,or rooms under bad ventilation condition .The room for installation shall be well ventilated and above 6m² in area .A ventilation hole as well as an exhaust hole must be drilled in the wall ,for venting hole shall be at the level lower than the water heater.(Fig.3) ...
Installation Method 1. Installation Drill holes in the wall according to Fig.6, put an expansion bolt into the upper hole and plastic gasket into the lower hole, mount the water heater vertically on the upper bolt without inclination and tighten the lower holes with expansion bolts. A B MINI 530.5 283.5 12 OF ErP Fig. 6 (Unit:mm) 2. Piping ● L.P.G users are recommended to use 2m³/h pressure –reducer. ● Gas inlet Faucets ⑴ For L.P.G users, connect the gas inlet faucet and the gas pressure‐reducer of the gas cylinder with special Ф9.5mm rubber tube, fasten the joints with clips. ⑵ For Natural Gas users, contact the gas dealer to connect with fit pipe. ⑶ After connecting the pipes, check the connections with soapsuds for gas leak. ● Water Inlet Faucet Remove the drain valve firstly to avoid breaking the anti‐frost pipe. It’s use the tube provided, or you may use rigid pipe as cold‐water connection. A water controller shall be installed before the water inlet faucet (Fig.7). (Note: There is a filter inside the water inlet faucet, do not remove it while installing). ...

● Hot Water Outlet If connect the hot water outlet directly to the shower, you can use tube or rigid pipe. When install control valve or tap to the hot water outlet, or install the shower with control tap, do not use pipes made of materials pressure‐unendurable or temperature‐unendurable, such as plastic pipes, aluminum pipes. 3. Battery Installation Do not confuse the positive and negative ends of the batteries (See Fig.8). 4. Flue Duct Installation As This type B appliances shall only be installed in the open air or in a room which is 11BS separated from inhabited rooms and supplied with appropriate ventilation directly to the outside.( The waste air exhaust pipe must be installed.) ● The main body of the flue duct shall be n=made or rustproof material. ● The horizontal part of the flue duct shall has an 1:100 down inclination, and there shall be a ф10mm hole at the bottom of the vertical part of the duct outside the room, for the purpose of draining water drops ● The outlet of the flue duct shall have a windproof cap, which should not be clogged. Installation method: ● Drill proper holes on the wall according to the right dimensions of the heater (See Fig.9). ...
Operation Method 1. preparation Before Ignition ● Make sure the type of gas used complies with that stipulated in the label. ● Open the ventilation holes. ● Turn on the gas inlet valve. 2. How To Ignite ● Turn on the water valve (make sure there is water flowing out of the shower), the water heater with “clicking” ignition sound. The burner is ignited and hot water flows out instantly. If the water pressure is low, or the power is not connected, the water heater will not operate normally. ● After initial installation or a change of gas cylinder air may remain in the gas pipe and it requires several ignition attempts to push the air out of the pipe before the gas can be ignited. If a problem comes up after normal operation, turn off the water immediately. Try to re‐ignite 10‐20 seconds later to avoid “pop” burning. ● Water Temperature Control ⑴ Turn the water flow control knob (rod) on the cover of (under) the machine to control the water flow and its temperature. Turn the gas regulator knob (rod) on the cover (bottom)to control the flame of the burner thus controlling the hot water temperature. (2) turn the water inlet tap to control water temperature: decreasing the water flow to make the water temperature high (do it slowly, if the flame extinguishes then re‐ignite by increasing the water flow), and increasing the water flow to make the water temperature low. ● Test water temperature with your hand before using to avoid scalding.(Fig.10) ● Turn off the gas valve after each shower.(Fig.11) ● When the outdoor temperature is below 0℃, the water heater must be drained after each shower as follows: ⑴ ...
Cautions For Safety ■ Gas Leakage Prevention ● It’s better to install a gas leakage‐warning device. ● Check whether the flame is extinguished after each shower and do not forget to turn off the gas valve(Fig.11) ● Always check all the gas pipe connections with soapsuds to see whether it has gas leakage. In case of gas leakage, shut off the gas supply and open the windows immediately. Under such condition, ignition, switching on/off the electric power supply are strictly prohibited to avoid explosion and firing.(Fig.12) 9 ...

● Keep on using one type of gas (L.P.G or NG), never mixing using them. ● Check the gas tube regularly as it may age and crack after long period of usage. Replace it if cracked tubes are found. Under normal operation, the gas tube should be replaced yearly. ● For L.P.G user, if the flame of the heater is not stable, it may be caused by the breakdown of the pressure reduction valve connected to the outlet of the gas tank. In that case, stop using the heater immediately and contact a service technician ● For NG users, if the flame of the heater is not stable, it may be caused by the instability of the gas pressure. In that case, stop using the heater, otherwise it may be damaged or even cause accident. ■ Fire Accident Prevention ● Make sure that the flame of the heater has extinguished before leaving the room or go to sleep. ● Turn off the main gas valve and the water inlet valve in case of water shortage. ● Do not place inflammables like towel or cloth onto the water air drain outlet or the air inlet.(Fig.13) ...

● Do not pile inflammables, explosives or volatile materials near the heater. (Fig.14) ● For L.P.G users, do not place the tank titled or inverted, otherwise the liquid in the gas cylinder may flow into the heater, and cause fired accident. Carbon Monoxide Intoxication Prevention The burning of gas consumes large amount of air and produces some amount of poisonous gas like carbon monoxide. Thus, the heater must be fixed in a ventilated location. Keep exhaust fan running and the ventilation hole opened. ...
knobs, especially the parts around the flame check window. The Following Things Are Normal When the water pressure is lower than 0.3bar, 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 too much points at the same time, the hot water flow would be reduced, and at times no hot will issue at all. During shower, if the heater is operated for more than 20 minutes, the flame will automatically turns off due to the 20‐minute timer safety protection function of the heater. Maintenance Check the gas tube/pipe regularly for any defect. Contact service center for any doubt. Clean the water filter regularly. Check the water leakage regularly. When the flame turns from blue to yellow with black smoke, contact the service center ...
