The hot water at the
fixture is too hot.
Are the gas and water supply valves fully open?
[Using the optional remote controller]
Is the water temperature setting appropriate? (page 13)
[Using the optional remote controller]
If the water supply temperature is high, it is possible
for the outlet temperature to be higher than the
temperature set on the remote controller.
[Using the optional remote controller]
If only a low flow of hot water is demanded, it is
possible for the outlet temperature to be higher than the
temperature set on the remote controller.
The hot water at the
fixture is not hot enough.
Are the gas and water supply valves fully open?

Is the water temperature setting appropriate? (page 13)
If the amount of hot water required is very high, it is
possible for the outlet temperature to be lower than the
temperature set on the remote controller.
Decrease the amount of hot water passing through the
unit and the temperature should stabilize.
The actual outlet water temperature is lower than the set
temperature of the unit.
Contact the nearest Noritz agent.
The water is cold when only
a single fixture is open.
The unit will not heat the water if the flow rate is less
than 0.5 gallons (2L) per minute.
Open the fixture more or open other fixtures so that
a greater flow passes through the unit, and the unit
should begin heating again.
The unit does not fire when
water is flowing due to high
supply water temperature.
If you try to supply a low flow of water when the supply
water temperature is too high.
The unit will not fire because it will over heat the outlet water.
Fluctuations in hot water
