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.
• The fan may run to prevent freezing.
The fan can be heard when it
is very cold outside.
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.
