It takes a long time to
get hot water at the
fixtures.
ͻ
The time it takes to deliver hot water from the water heater to your fixtures
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.
ͻ
If you would like to receive hot water to your fixtures more quickly you
may want to consider a hot water recirculation system. (p. 40)
The water is not hot
enough.
ͻ
Compare the flow and temperature. See the charts on p. 64.
ͻ
Check cross plumbing between the cold water lines and hot water lines.
ͻ
Is the gas supply valve open fully? (p. 42)
ͻ
Is the gas line sized properly? (p. 30)
ͻ
Is the gas supply pressure sufficient? (pp. 29 and 51)
ͻ
Is the set temperature set too low? (p. 47 and 49)
The water is too hot.
ͻ
Is the set temperature set too high? (p. 47 and 49)
The hot water is not
available when a
fixture is opened.
ͻ
Make sure the unit has 120 VAC, 60 Hz power supply.
ͻ
If you are using the remote controller and/or temperature controller, is
the power button turned on?
ͻ
Is the gas supply valve open fully? (p. 42)
ͻ
Is the water supply valve open fully? (p. 42)
ͻ
Is the filter on the cold water inlet clean? (p. 51)
ͻ
Is the hot water fixture sufficiently open to draw at least 0.5 GPM
(1.9 L/min) through the water heater? (p. 46)
ͻ
Is the unit frozen? (p. 50)
ͻ
Is there enough gas in the tank / cylinder? (For Propane models)
The hot water turns
cold and stays cold.
ͻ
Is the flow rate enough to keep the water heater running? (p. 46)
ͻ
If there is a recirculation system installed, does the recirculation line have
enough check valves? (p. 40)
ͻ
Is the gas supply valve open fully? (p. 42)
ͻ
Is the filter on the cold water inlet clean? (p. 51)
ͻ
Are the fixtures clean of debris and obstructions?
ͻ
Check if the flow rate is too low. (p. 46)
Fluctuation in hot
water temperature.
ͻ
Is the filter on the cold water inlet clean? (p. 51)
ͻ
Is the gas line sized properly? (p. 30)
ͻ
Is the supply gas pressure sufficient? (pp. 29 and 51)
ͻ
Check for cross connection between the cold water lines and hot water
lines.

Unit does not ignite
when water goes
through the unit.
ͻ
Is the flow rate over 0.5 GPM (1.9 L/min)? (p. 46)
ͻ
Check for the filter on the cold water inlet. (p. 51)
ͻ
Check for reverse connection and cross connection.
ͻ
If you use the remote controller and/or temperature controller, is the
power button turned on?
ͻ
Check if the inlet temperature is too high. If it is too close to the set
temperature, the water heater will not activate.
The fan motor is
still spinning after
operation has stopped.
ͻ
This is normal. After operation has stopped, the fan motor keeps running
from 15 to 70 seconds in order to re-ignite quickly, as well as purge all the
exhaust gas out of the flue.
Unit sounds abnor-
mal while in opera-
tion
