Display Window
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 xture sufciently 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 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.
Frequent water discharge
from the drain pipe.
Condensation forms inside the unit during operation
and is discharged from the drain pipe.
