The heater stops burning during operation. 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?)
White smoke comes out of the exhaust vent
(terminal) on a cold day.
This is normal. The white smoke is actually steam.
The hot water is turbid. This is harmless. Small bubbles appear as the air in the water is
heated and depressurized rapidly to atmospheric pressure.
The water appears blue.
The bath tub/wash-basin has turned blue.
Coloration to a blue color may be noticed from small traces of
copper ion contained in the water and fat (furring). However,
there are not problems concerning health. Coloration of the bath
tub/wash-basin can be prevented by cleaning frequently.
