Special Advice The combustion of the gas will consume a large amount of air and produce Carbon Monoxide while the heater is working. NOTICE: if humans or animals breathe too much Carbon Monoxide, it will cause danger, injury, or even death. Therefore, the users are requested to install and use this heater strictly according to this manual to avoid Carbon Monoxide toxicosis.

Installation Before installation, contact the qualified technicians at your local gas dealer or gas management department to do the installation. Any random or improper installation will affect the safe use of the machine or even endanger the users’ life. If the water heater installation is in a room with other ventilation devices, it is strictly prohibited to operate additional ventilation equipment (like a stove hood or ventilation fan) As this can cause a back draft of the heater.
the floor. Fig.4), and always kept well away from inflammable liquids and materials. (Fig. 5). No electric cables or equipment shall be placed above the water heater. The heater shall be kept at least 400mm (16 inches) away from all electronics on sides and bottom. Do not install the water heater where strong winds blow, or it can cause flameout or incomplete combustion. Installation Method 1. Installation Drill holes in the wall according to Fig.
Hot Water Outlet Remove the drain valve first to avoid breaking the anti-frost screw. If connecting the hot water outlet directly to the shower, you can use tubing or rigid pipe. When installing the control valve or tap to the hot water outlet, or installing the shower with control tap, do not use pipes made of materials pressure-unendurable or temperature-unendurable, such as plastic or, aluminum pipes. 3. Battery Installation Do not confuse the positive and negative ends of the batteries (See Fig. 8).
Operation Method 1. Preparation before Ignition Make sure the type of gas used complies with that stipulated on the label. Natural gas or Propane (LPG) Turn on the gas inlet valve. Turn on the water valve (make sure there is water flowing out, the green indicator light will turn on with a "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.
3) Remove the drain cock. (The drain cock is a bolt connected to the valve. Take it off by turning it counter-clockwise to drain the water completely). Cautions For Safety ■ Gas Leak Prevention It's best to install a gas leakage-warning and carbon monoxide detection device. Do not forget to turn off the gas valve after use (Fig. 11) Always check all the gas pipe connections with soapsuds to see whether it has gas leakage.
Do not place inflammable materials, explosives or volatile materials near the heater. (Fig.14) For L.P.G users, do not place the tank tilted or inverted, otherwise the liquid in the gas cylinder may flow into the heater, and cause a fire or explosion accident. ■ Carbon Monoxide poisoning Prevention The burning of gas consumes large amounts of air and produces some amount of poisonous gases like carbon monoxide. Thus, the heater must be fixed in a very well ventilated location.
● In case of abnormal burning (e.g. flame back, flameout, yellow flame or black smoke, etc.), an unusual smell, noise or other abnormal matters, keep calm and turn off the gas valve and contact EZTANKLESS. ■ Preventing Scalding ● After repeated use, or when the water temperature control knob is still at “high” position, be careful of the temperature of the water at the beginning and ending of each use, as it may remain high and scald your skin.
