When an error code appears, the display and the operation light
will flash together.

(If the alarm doesn't sound)
• Open a door or window to let air in.
• Close the hot water fixtures.
• Press the power button to turn the unit off.
If the error code does not return when the unit is

turn it down.

Check whether the gas valve is open. Press the power
