Temperature and amount of hot water
Possible solutions
The time it takes to deliver hot water from the water heater to your fixtures
depends on the length of piping between the two. The longer the distance or
the bigger the pipes, the longer it will take to get hot water.
If a tempering valve is installed, is it set too low or malfunctioning?
Are the cold water and hot water lines cross connected?
Is the gas supply valve fully open?
Is the gas line sized properly?
Is the gas supply pressure enough?
Is the set temperature set too low?
Is the combustible air inlet or exhaust outlet blocked?
Is the set temperature set too high?
Does the water heater have a 240V 50Hz power supply available?
If you are using the remote controller, is the power button turned on?
Is the gas supply valve fully open?
Is the water supply valve fully open?
Is the filter on cold water inlet clean?
Is the hot water fixture sufficiently open to draw at least 3.0l/min through the
water heater?
Is the water heater frozen?
Is there gas available to the water heater and (if applicable) does the gas
storage tank have enough gas in it?
Is the flow rate enough to keep the water heater running?
Is the gas supply valve fully open?
Is the filter on the cold water inlet clean?
Are the fixtures clean of debris and obstructions?
Is the filter on the cold water inlet clean?
Is the gas line sized properly?
Is the supply gas pressure enough?
Are the cold water and hot water lines cross connected?
Water heater
Possible solutions
Is the flow rate over 3.0l/min?
Is there a 240V 50Hz power supply available to the water heater?
Are the cold water and hot water lines cross connected or reversed?
If you use the remote controller, is the power button turned on?
This is normal. After operation has stopped, the fan motor keeps running for
15 – 75 seconds in order to re-ignite quickly, as well as push all exhaust gas
out of the flue.
It is normal to see water vapour clouds or steam coming from the hot air outlet
of the water heater especially during cold and wet days.
Remote controller (optional)
Possible solutions
Press the ON/OFF button.
If the lamp does not light:
Make sure the water heater has power supply.
Make sure the connection to the water heater is correct.
Call a service technician.
Is priority lamp lit? If it is not, press the priority button after closing all
hot water taps.
