NAME OF PARTS

INSTALLATION

Installation Requirement

• Do not install the water heater in a bedroom, basement, bathroom, or any room with poor ventilation. To keep the installation room wellventilated, an air-intake (inlet) hole should be made in the lower area of the room, and the area around the hole should not be less than 100 cm.
• The flame observation window of the water heater should be in a position where it can be easily viewed (apprOximately 150 cm above the floor).
• No cord or electric equipment should be put above the water heater.
• The water heater should be kept at least 40 cm away from the electronics horizontally. The water heater should be kept away from any flammable substance or liquid.
• Do not install the water heater where adverse winds may blow, causing flame-out or incomplete combustion.

Indoor Installation Position

NOTE

• The positions of the water inlet, water outlet, and gas pipe must be in accordance with the marks on the water heater body.
• Check carefully after the installation has done; make sure that there is no gas or water leak.
• The maximum length of the rubber hose is 2 meters.
• Cable, hose, and pipe are prohibited to pass the side or the upper of the water heater body.
• The installation of the hanger must be horizontal.

Hanger Installation

Water Heater Hanger

The water heater should be hanged vertically. The standard height of the water heater is adjusted with the position flame parallel observation window (peeping hole) to the human eyes.

Ventilation Pipe Installation
The water heater must have ventilation pipe. The installation of the ventilation pipe must be in accordance with follow matters:

• The height of the ventilation pipe must be in accordance so that it can exhaust the smoke out.
• The horizontal part of this ventilation pipe must be les than 3 m, and the pipe must be a bit tilted down (1), so that the water Condensation does not flow back.
• The angle of the ventilation pipe must be 90°, and its quantity should be no more than 3 pieces.
• Inside the ventilation pipe, the upper hole of the smoke exhaust (flue) duct from the back must have more than 250 mm height.
• The upper part of the ventilation pipe must be accompanied with the windproof COver to prevent Wind and rain.
• The distance may not be more than 600 mm from the surrounding buildings.
• Do not install the ventilation pipe in the air replacement part or smoke ventilation track.
• Make sure there is no air leak at the pipe connections; fasten it with strong screws.

How to Install the Ventilation
The air hole must be on the good ventilating position and placed 1/2 under the height of the room.
The pipe hole must be made outside, close from the upper part of the room, and far from the ventilation pipe.

Gas Pipe Installation
The diameter of the threaded bolt that connects the gas inlet pipe to the water heater is G1/2.

Connecting to the LPG Tank

• Install the connector in the package to the gas inlet valve on the water heater (make sure the seal has been installed). Then, connect it to the hose for gas (rubber hose) with
  a diameter of 9.5 mm as shown in the picture.

• Make sure to use the gas regulator with the right pressure (the exact gas pressure standard is 2800 Pa for LPG, 2000 Pa for natural gas).

Connecting to the Gas Pipe

• It must use the gas hose or standard metal pipe.
• Gas valve must be installed at the gas inlet pipe.

Valve Installation
Valve must be installed at the gas inlet pipe, water inlet pipe, and water Outlet pipe. After the installation, checking must be done tO make sure that there is no gas or water leak.

HOW TO USE

Preparation

1. Insert 2 pieces of battery. Make sure the positive and negative poles of the battery are well-installed (not reversed).
2. Open the gas inlet and water inlet valves.

Turning On the Water Heater
When the water pressure is above 0.015 MPa, the water heater will be turned on automatically if the hot water valve is opened. For the water heater that is just installed, the gas pipe perhaps is filled with air and cannot be turned on at the first time. Repeat the on and off process to exhaust the air out until the water heater turns on.

Temperature Control

1. Adjust the water and gas controller knobs until the desired hot water temperature is reached.
2. If the water inlet valve is installed, cold water valve may not be rotated excessively, to prevent the reduction of the pressure (as a cause of the pipe and the valve diameters difference) that affects the normal operation of the water heater
3. At certain places, the water pressure maybe too strong and thus the water cannot be heated. In this case, please turn the water inlet valve down (as shown in the illustration picture below).
4. Flame can be adjusted by turning the flame controller knob to the ‘max’ or ‘min’ position (refer to the illustration picture below).

Turning Off the Water Heater
To turn the water heater off, switch off the hot water outlet valve or the water inlet valve. Then, the flame will automatically extinguish, and the water heater Will return to stand-by mode.

NOTE
The water heater cannot be used continuously for a long time. It will automatically turn off after 20 minutes in continuous operation to prevent the accidental carbon monoxide poisoning due to inadvertent or accidental long- period use.

MAINTENANCE

This gas instant water heater must be checked by professionals every 6-12 months. Parts of the water heater that need to be checked are in the following:

1. Seal of the gas and water track system.
2. Flexibility of the water and gas piping connection.
3. Functions of all the operating parts.
4. Burner of the flame (for combustion)
5. Air loading and releasing/relief system inside of the room where the water heater is installed.
6. Gas pressure reducer.
7. Apply the lubricants to the gas valve and on its middle part.

Parts of water heater that must be cleaned by professional

1. Filter at the edge of the water supply line to prevent congestion.
2. Carbon crust on the buckled part of the heat exchange
3. The disturbing carbon accumulation and oxidation layer in the gniter.

Maintenance of the water heater by user:

1. Clean off the dirt and dust accumulation on the surface of the water heater with the cloth regularly. Do not use chemical that
   can change the color of the surface

2. Clean off the dust and the carbon accumulation inside of the ventilation pipe and the heat exchanger regularly to smooth out the smoke line.

NOTE
Remove the ventilation pipe; and clean the heat exchanger part with a soft brush. During the cleaning, do not let the dirt and dust enter the fire hole of the burner and also into the part of electric tools. Do not eliminate or damage the tools. When re-install ventilation pipe after cleaning, make sure to fasten all parts of connector.
