the connecting lines at the appropriate temperature to prevent damage from freezing.

When you leave your house in the cold seasons, the power plug of the boiler must be

connected to the receptacle and the fuel (gas) valve must be open.

During severe winter weather, set the temperature at around 10-15 to prevent the unit from freezing.

In the situation that falls under any of the instances below, the freeze protection function will not work:

Power failure or boiler power cord is unplugged.

Fuel (gas) supply valve is closed, or fuel supply is cut off.The water feed pipe oran other exposed pipe is not properly heat insulated.

If you plan to use a lot of hot water, press theBath button.

The boiler returns to normal after two andhalf hours after toggling the Bath mode.

The water pressure should be higher than78-147 (0.8-1.5kgf/ ). If your water pres-sure is higher than recommended, install adecompression device.

How to Use the Temperature Customizing Function

Be careful of getting burned when using hot water.Hot water may pour out suddenly when you turn on the hot water faucet after toggling the bath function.Pay attention to children, the elderly, or the disabled.The water is not recommended for drinking.The customized temperature function is available when the valve is completely set to hot water whilethe boiler is operating in its heating modeUsing hot water for an extended period of time in the heating mode may result in lukewarm water.Turning the boiler on/off in the Bath mode reverts the boiler to a normal heating mode.
