Trouble Possible Cause Remedy
Hot water is not
the right
temperature
(too hot or too
cold).
Temperature set
point was reset due
to power outage.
Temperature set
point incorrect.
Flow is beyond
capacity.
Incoming water is
too warm.
Power outage restores default
settings and custom set points
must be re-entered to unit
A remote wired controller is
controlling temperature set
point. Release override control
of this remote (see “Remote
Control Panel Functions”) or
change set point to desired
temperature with that remote.
Desired water flow is above
maximum capacity of unit.
Reduce user flows to re-
establish control of temperature
If incoming water to unit is very
warm and the flow is just above
minimum requirements, the heat
generated by the burner while
operating at minimum capacity
can make the water hotter than
desired. Increase the hot water
user flow so that the burner
system can control the
temperature.
Hot water flow
produced is lower
than expected.
Water source is
restricted.
Heat exchanger in
unit is scaled.
Incoming water
temperature is
colder than
expected.
Check and fully open water inlet
valve(s)
Check and clean inlet water filter
Clean heat exchanger by flushing
per maintenance procedure.
Colder than normal incoming
supply water will reduce the
amount of hot water than can be
produced.
Trouble Possible Cause Remedy
Although the amount of heat
output from the unit is still at full

manner.
Check air intake and exhaust
ducts to ensure they are not
damaged, corroded, blocked,
