4. Safety Measures

General Safety

• Always close the main gas supply to the heater to prevent gas leakage.
• Do not place any cloth or towel on top of the gas water heater.
• If you detect any smell of gas leakage, immediately close the gas cock, open all doors and windows, and do not switch on/off any electrical instrument. Call a qualified service technician immediately.
• Avoid touching the burner viewing window while the heater is operating.
• Check the gas pipe regularly for aging cracks. It is recommended to replace rubber gas tubes every six months to prevent gas leakage.

Freezing Prevention

• In winter, if the water temperature drops below 4°C, completely drain water from the gas water heater through the drain valve to prevent damage due to freezing.
• If the water heater will not be used for a long time:
  1. Drain water from the gas heater drain valve.
  2. Remove the batteries from the battery box.

5. Installation

Important Installation Notes

• Before using the heater, read these instructions carefully.
• Correct installation is crucial for satisfactory performance.
• Installation and inspection must be performed by a qualified and authorized technician.

Location

• It is advisable to install the gas water heater outside the bathroom.
• If installed inside the bathroom, ensure sufficient ventilation. Consult an authorized technician.
• The heater requires a plentiful supply of fresh air. Fixed ventilators or air inlets near the heater should never be obstructed.
• There should be at least one window or door opening directly to the outside or to a well (OTS).
• Air from outside should be able to enter the bathroom/location where the heater is installed through an inlet in a wall, door, or window. The direct air inlet section should be at least 1.5 sq. feet.
• The burner viewing window should be at 1.4 to 1.5 meters height from the ground.
• Maintain a minimum distance of 1 foot between the top of the gas heater and the ceiling for easy removal of flue gases.

Fixing the Unit

1. Drill two holes in the wall and fix the screw nails. Mount the Gas Heater on the nails.
2. Ensure the gas and water connection pipes are free of dirt/waste material and thoroughly clean.
3. Connect the Gas pipe, Inlet, and Outlet water connections.
4. Insert two 1.5V D-type batteries into the battery box, ensuring correct polarities.
5. Before starting, ensure there is no gas leakage from the gas connection.

6. Operating Instructions

1. Starting the Heater: Open the water tap. As water starts flowing, the multiple spark will ignite the main burners. If burners do not ignite, close the tap and repeat the operation. This may happen due to excess air in the gas pipe.
2. Gas Regulator Control Knob: Turn the gas knob clockwise to increase gas supply and anti-clockwise to decrease it.
3. Water Regulator Control Knob:
   • To get more hot water, reduce the flow rate by turning the knob clockwise.
   • To increase water flow rate and reduce hot water temperature, turn the knob anti-clockwise.
   • The hot water temperature can be controlled by adjusting both the gas control knob and/or the water flow control knob.
4. Shutting Off: To shut off the gas water heater, simply close the water tap.
5. Summer and Winter Knob: Regulate the quantity of fire rows using the winter-summer switch device. In summer, shut off 1/4 of the fire rows to save 40% energy.

7. Maintenance

• The heater must be checked annually for safe operation, regardless of frequency of use. This check should focus on the correct combustion of the main burners.
• Maintenance should only be carried out by a qualified and authorized technician.
• If the heater is installed in a hard water area, scale formation may occur over time, leading to a fall in hot water temperature or a reduction in hot water flow.
• To reduce scaling, it is recommended to use the water and gas control knobs to obtain the desired water temperature instead of mixing cold water with hot water.
• Scaling should be removed only by an authorized technician.

10. User Tips

• Initial Setup: Ensure all water and gas connections are firm and correct before attempting to operate the heater. The unit requires 2x 1.5V D-type batteries for ignition, which are not included.
• First Use Venting: Before the very first use, it is crucial to vent any air residue from the pipelines. Failure to do so may lead to poor water flow or potential damage to the machine.
• Continuous Heating: The water heater includes a 20-minute in-built timer. For continuous hot water, you may need to restart the unit after this period.
• Water Pressure: The unit is designed to handle water pressures between 0.02 MPA and 0.8 MPA, with a starting pressure of 0.015 MPA. Ensure your water supply meets these requirements for optimal performance.
