What to Do
• Some amount of fan noise is normal (similar
to the blower on a central heating and cool-
ing system). If you hear an abnormal noise like
a knocking of the noise level seems unusually
loud, then contact service.
• If noise level has been increasing over
several 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 wa-
ter 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.
• 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 sections.
• See the water temperature setting section.
• This is normal. The colder inlet water takes
longer to heat.
• See the water temperature setting section.
• Call for service.
• Remove and clean the heating elements.
