GENERAL TROUBLESHOOTING
TEMPERATURE and AMOUNT OF HOT WATER
PROBLEM POSSIBLE SOLUTIONS
It takes a long me to get hot
water at the taps.
• The me it takes to deliver hot water from the water heater to your
taps 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.
The water is not hot enough. • Compare the ow rate and temperature. See the chart on p. 28.
• Check cross plumbing between cold water lines and hot water
lines.
• Is the gas supply valve fully open? (p. 17)
• Is the gas line sized properly? (p. 10)
• Is the gas supply pressure enough? (p. 11)
• Is the set temperature set too low? (p. 18,19)
The water is too hot. • Is the set temperature set too high? (p. 18,19)
The hot water is not available
when a xture is opened.
• Make sure the unit has 240V 50Hz power supply.
• If you are using the remote controller, is the power buon turned
on? (p. 18,19)
• Is the gas supply valve fully open? (p. 17)
• Is the water supply valve fully open? (p. 17)
• Is the lter on cold water inlet clean? (p. 21)
• Is the hot water xture suciently open to draw at least 3.0 l/min
through the water heater? (p. 18)
• Is the unit frozen?
• Is there enough gas in the tank? (for propane)
The hot water gets cold and stays
cold.
• Is the ow rate enough to keep the water heater running? (p. 18)
• Is the gas supply valve fully open? (p. 17)
• Is the lter on cold water inlet clean? (p. 21)
• Are the xtures clean of debris and obstrucons?
Fluctuaon in hot water temperature • Is the lter on cold water inlet clean? (p. 21)
• Is the gas line sized properly? (p. 10)
• Is the supply gas pressure enough? (p. 11)
• Check for cross connecon between cold water lines and hot water
lines.
