THE FOLLOWING CONDITIONS 

ARE NOT A FAULT

Phenomenon

Reason and Handling Method

Exhaust white Smoke

INDOOR 

temperature is too low. The exhausted 

smoke encountered the cold air and then is 

condensing into a white mist.

Flow rate of generated 

hot water is too small to 

achieve requested water 

temperature

Hot water flow is too low to ignite the water heater. 

The water heater will not turn on if the flow is too 

low and then the water will become cold. Raise the 

flow rate higher to activate the heater.

Can’t supply high 

enough temperature in 

winter

The incoming water temperature is very low and 

the water adjustment knob is already turned to 

maximum. The set temperature may be more 

than the heating capacity allows. Please adjust 

the flow lower to allow the water to heat to higher 

temperatures.

Water is too hot during 

the summer

Incoming water temperature is too high and the 

incoming flow is too low. It may cause the hot 

water to be too hot. Please adjust the flow to be 

more to lower the temperature.

The water heater turns 

off after 40 minutes

In order to prevent hypoxia, some models have a 

40 minute timer protection function. When you 

continuously use the water heater for 40 minutes, 

it will turn off. Please turn off the tap and restart.

Close the hot water 

valve, but the fan does 

not stop immediately

The fan has a delay in the shutdown function in 

order to completely clean the water heater exhaust 

to ensure the safety of users.

Open the hot water 

valve, but hot 

water does not flow 

immediately

There is a distance from the water heater to the 

outlet, so the cold water in the line must flow out 

before the hot water reaches your outlet. The 

farther the distance from the water heater, the 

more time it takes to receive hot water.

There is always some 

water from the drain 

valve

This is because the inlet water pressure is too high 

and the drain valve will work to release the high 

pressure. Try to reduce the inlet water pressure by 

turning down the gate valve or the ball valve until 

water leakage stops.
