Temperature
Hot water is not available
when a fixture is opened.
• Are the gas and water supply valves fully open?
• Is the water supply cut off?
• Is the hot water fixture sufficiently open?
• Is the gas being cut off by the gas meter?
(Can other gas devices such as stoves be used?)
• (For LP) Is there enough gas in the tank?
(Can other gas devices such as stoves be used?)
• Is the water drain valve filter clogged? (
p.22)
• Is the power button turned on?
• Are the gas and water supply valves fully open?
• Is the water temperature setting appropriate?
( p.12 and p.13)
• If the water supply temperature is high, it is possible
for the temperature to be higher than the temperature
set on the remote controller.
• If only a small amount of hot water is demanded, it is
possible for the temperature to be higher than the
temperature set on the remote controller.
The water is too hot.
• Have you allowed enough time for the cold water in the

Water takes time to become hot
when turning the hot water fixture.
No water is available when

(Continued)
• Are the gas and water supply valves fully open?
• Is the water temperature setting appropriate?
( p.12 and p.13)
• If the amount of hot water required is very high, it is
possible for the temperature to be lower than the temp-
erature set on the remote controller.
Decrease the amount of hot water passing through the unit
and the temperature should stabilize.
The water is not hot enough.
