8.2 GENERAL TROUBLESHOOTING

~ TEMPERATURE and AMOUNT OF HOT WATER ~
PROBLEM
It takes long time to get hot water at
the fixtures.
The water is not hot enough.
The water is too hot.
The hot water is not available when a
fixture is opened.
The hot water gets cold and stays
cold.
Fluctuation in hot water temperature.
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 larger the pipes, the longer it will take to get hot
water.
• Compare the flow and temperature. See the chart
on p. 24.
• Check cross plumbing between cold water lines and
hot water lines.
• Is the gas supply valve fully open? (p. 18)
• Is the gas line sized properly? (p. 12)
• Is the gas supply pressure enough? (p. 13)
• Is the set temperature set too low? (p. 23)
• Is the set temperature set too high? (p. 23)
• Make sure the unit has 240V 50Hz power supply.
• If you are using the remote controller, is the power
button turned on? (p. 19 )

• Is the water supply valve fully open? (p. 18)
• Is the filter on cold water inlet clean? (p. 20)
• Is the hot water fixture sufficiently open to draw at
least 3.0l/min through the water heater? (p. 19)
• Is the unit frozen?
• Is there enough LPG in the bottle? (for propane)
• Is the flow rate enough to keep the water heater
running? (p. 19)
• Is the gas supply valve fully open? (p. 18)
• Is the filter on cold water inlet clean? (p. 20)
• Are the fixtures clean of debris and obstructions?
• Is the filter on cold water inlet clean? (p. 22)
• Is the gas line sized properly? (p. 12)
• Is the supply gas pressure enough? (p. 13)
