Remote Controller
The water temperature changes
after a power failure or when the
power is disconnected.
The light on the power button
does not come on.
• Has there been a power failure?
• Is the power connected properly?
• The temperature setting and the flow meter alarm setting
may both need to be reset after a power outage.
Sounds
The fan can be heard after
operation is stopped.
A motor can be heard when turning
the unit ON or OFF, when opening
or closing a fixture, or after the unit
has been running for a while.
• These noises indicate the proper operation of devices
which are designed to let the unit reignite more quickly,
and ensure the water temperature is stable.
Other
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?)
• This is normal. The white smoke is actually steam.
White smoke comes out of the
exhaust vent on a cold day.
The hot water is turbid.
• This is harmless. Small air bubbles appear as the
water is heated and depressurized rapidly to
atmospheric pressure.
Water leaks from the drain plugs
on the outlet.
• When the unit is under very high pressure, water will leak
from the drain plugs as a safety so that the unit is not
damaged by the high pressure.
