Possible Causes
Fans are used to move air
through the system. The fan
noise volume will vary as the
water is heated.
Room is not vented
properly or is too small.
Condensate drain hoses are
not connected.
Condensate drain hoses are
kinked or clogged.
Hot/Cold water connections
are not tightened.
Water usage may have
exceeded the capacity
of the water heater.
A fuse is blown or a circuit
breaker tripped.
Electric supply may be off.
Water temperature may
be set too low.
Leaking or open hot water
faucets.
Electric service to your home
may be interrupted.
Improper wiring.
Manual reset limit (TCO).
Cold water inlet temperature
may be colder during the
winter months.
Water temperature is set
too high.
CAUTION:
For your safety, DO NOT attempt repair of electrical wiring, controls,
heating elements or other safety devices. Refer repairs to qualified service personnel.
Electronic control has failed.
Water conditions in your
home caused a buildup of
scale or mineral deposits
on the heating elements.
What To Do
•
Some amount of fan noise is normal (similar to the blower
on a central heating and cooling system). If you hear an
abnormal noise like a knocking or the noise level seems
unusually loud, then contact service.
•
If noise level has been increasing over the last weeks or
months, the filter may be getting dirty, thus making the
fans work harder. Check to see if filter needs to be cleaned.
(See page 13 for instructions.)
•
If the room is smaller than 10' x 10' x 7', then it must have
a louvered door or other means to allow air exchange
with surrounding rooms.
•
Two drain hoses are included with your water heater.
Connect the longer 6' hose to the lower condensate drain
port. Connect the short 3" hose to the upper condensate
drain port.
•
Remove each drain hose and clear any debris from the
line. You can use a small wire like a hanger or a small
screwdriver to clear out any debris in the drain port on
the unit.
•
Tighten the inlet and outlet pipe connections.
•
Wait for the water heater to recover after an abnormal
demand.
•
Replace fuse or reset circuit breaker.
•
Make sure electric supply to water heater and disconnect
switch, if used, are in the ON position.
•
See the Water temperature setting section.
•
Make sure all faucets are closed.
•
Contact the local electric utility.
•
See the Installation Instructions section.
