LOCATION & WATER
HEATER CLEARANCE
Locate the water heater in a clean dry area as near
as practical to the area of greatest heated water
demand. Long uninsulated hot water lines can waste
energy and water.
Place the water heater in such a manner that the
electric junction box, the overflow line cover, the
upper element cover and the lower access panel can
be removed to permit inspection and servicing such
as removal of elements or checking controls.
The water heater and water lines should be protected
from freezing temperatures.
To allow easy access for operation and maintenance,
we recommend leaving the following clearances
around the water heater: At the front and above
the water heater: 25’’. Left and right: 4’’. Back: 2’’
provided that the overflow line can be correctly
installed. In case of any doubt, please check your
local codes.
