water inlet

1. 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.
2. 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. 10)
3. 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.

■ 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.

3. Installation of the flue:

■ Flue Duct Installation of Forced-Exhausted Gas Water Heater (B23, B53 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. Refer 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.
2. The length of the flue duct should be less than 8m,
3. The horizontal distance of the flue duct is the shorter the better. The flue duct end should have a 2^ downward inclination (Fig. 11), so as to let the condensing water flows out.
4. 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 heat shield material to pack the flue duct with the thickness over20mm. (Refer to Fig.8)
5. No cement between the flue duct and wall for the convenience of maintenance.
6. The flue duct should be fixed tightly. The connection part could use self-adhesive foil to avoid the waste gas going back into the room.

■ 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.

■ 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. 17)
• Do not store inflammables, explosives or volatiles near the water heater. (Fig. 18)
• Never incline the gas tank or turn it upside down, the fluid gas is easy to flow into the heater and cause fires (G30).

■ 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. 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
• The water in the heater is not suitable for drinking.

■ 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

• 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.

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, 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 to reduce the pressure and 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 condensed 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 cannot be ignited, please choose the suitable shower function.
• 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. Seethe 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.
