Clearances And Accessibility - Power Flex Power VentedGas Water Heater Manual

Important: The water heater should be located in
an area where leakage of the tank or connections will
not result in damage to the area adjacent to the water
heater or to lower floors of the structure. Due to the
normal corrosive action of the water, the tank will
eventually leak after an extended period of time.
Also any external plumbing leak, including those
from improper installation, may cause early failure
of the water tank due to corrosion if not repaired.
A qualified service technician should be contacted
for repairs. A suitable metal drain pan should be
installed under the water heater as shown below, to
help protect the property from damage which may
occur from condensate formation or leaks in the pip-
ing connections or tank. The pan must limit the water
level to a maximum depth of 1-3/4" and be two inches
wider than the heater and piped to an adequate drain.
The pan must not restrict combustion air flow. Locate
the water heater near a suitable indoor drain. Outside
drains are subject to freezing temperatures which can
obstruct the drain line. The piping should be at least
3/4" ID and pitched for proper drainage.
Under no circumstances will the manufacturer or
seller of this water heater be held liable for any
water damage which is caused by your failure to
follow these instructions.
1-3/4"
max.
At least 2" greater than the
the water heater and the inlet
air pipe.
• The water heater should be located in an area not
subject to freezing temperatures. Water heaters
located in unconditioned spaces (i.e., attics,
basements, etc.) may require insulation of the
water piping and drain piping to protect against
freezing. The drain and controls must be easily
accessible for operation and service. Maintain
proper clearances as specified on the data plate.
• Do not locate the water heater near an air-moving
device. The operation of air-moving devices such as
exhaust fans, ventilation systems, clothes dryers,
fire-places, etc., can affect the proper operation of
the water heater. Special attention must be given to
conditions these devices may create. Flow rever-
sal of flue gases may cause an increase of carbon
monoxide inside of the dwelling.

Clearances and Accessibility

Notice: Minimum clearances from combustible
materials are stated on the data plate located on the
front of the water heater.

Important: If installing over carpeting, the carpeting
must be protected by a metal or wood panel beneath
the water heater. The protective panel must extend
beyond the full width and depth of the water heater by at
least 3 inches (76.2mm) in any direction or if in a alcove
or closet installation, the entire floor must be covered by
the panel.
Figure 1 may be used as a reference guide to locate the
Pipe to an
specific clearance locations. A minimum of 24 inches
adequate drain
of front clearance and 4 inches on each side should be
provided for inspection and service.
