Try using another electrical appliance.
COLD WATER FROM THE HOT TAP
Is the controller turned on?
Press the on / off button.
Close the hot tap, wait 10 seconds and open the hot tap again.
Is the hot tap open enough?
The burners will not light if the flow rate is less than 2.0 L / min.
Is the water heater plugged in and the power outlet switched on?
Is power available in the premises?
Try using another electrical appliance.
Is the isolation valve in the gas line open?
Is there a gas supply to the rest of the premises?
Try lighting another gas appliance.
Has the gas line been purged of air after installation? Refer to your plumber.
WATER IS TOO HOT OR NOT HOT ENOUGH
Is the preset outlet temperature of the water heater higher than required?
Does the controller you are using have priority?
REDUCED HOT WATER FLOW WHEN HEAT EXCHANGER IS COLD
At a cold start-up, i.e. when the water heater has not operated for some time (which is most often first thing
in the morning), the initial flow of hot water may be reduced for a period of 5-10 seconds while the heat
exchanger warms up. This is both an energy and water saving feature of this water heater. Once the
heat exchanger has warmed up the hot water flow will increase and remain at normal flow levels. This
feature will only occur at a cold start-up and not when the heat exchanger is already warm from a recent use
of hot water.
WATER FLOW FLUCTUATES
More than two or three taps in use at the same time may cause a decrease in the hot water flow from the
taps. This can also be evident if the water heater has been installed as an in-series gas booster to a solar
water heater and the solar heated water is at a low temperature.
Are there more than two or three taps open, or are appliances such as a dishwasher or washing
machine, in use at the same time?
Ensure only two or three taps or appliances are on at the one time.
Check the flow of the water from one tap, e.g., the shower.
The shower should be adjusted so the hot tap is fully open.
